[0:00] I'm willing to bet that you've probably seen
something like this.
[0:03] Someone walking around with their laptop screen
half open,
[0:06] and you know that if they're a programmer,
they're waiting for their agent to finish running.
[0:10] I know that this has been me many times.
[0:12] Even the other day at the airport,
[0:13] I was walking around with my laptop screen open,
looking like a complete idiot
[0:17] because I needed my Claude code or codex
agent to finish running.
[0:21] Now, this is a problem that doesn't need to exist
[0:24] because you can actually run agents in the cloud
if you configure them correctly.
[0:28] And that's
what I'm going to show you how to do in this video.
[0:30] I'm going to show you how we can set up Codex
that's running 24 over seven in the cloud.
[0:34] So we never need to have our laptop screen half open
walking around looking like a complete idiot.
[0:40] So effectively, what I'm going to show you in
this video is how you can run long running
[0:44] agent decoding tasks in the cloud, self-hosted
using your existing subscriptions.
[0:50] This means that you can be on the go, and then you
can actually trigger a task to run from your phone.
[0:54] You can reconnect to it from your laptop,
but the important part is
[0:57] that if that screen closes,
your task is going to keep running.
[1:01] Which means if you're sleeping
or if your Wi-Fi goes out, or if you're in an area
[1:05] where you just can't open your laptop,
you can still trigger these agenetic tasks to run,
[1:09] and you can actually run them on a schedule,
which we'll look at a little bit later.
[1:12] Now for this video, we're going to use Codex.
[1:13] The reason for this is the Codex.
[1:15] In my opinion, is currently the best agent out there.
[1:18] Specifically, we're going to be using Codex CLI.
[1:20] This is something that can run
in a headless environment
[1:23] and that we can execute from our phone,
which I'll show you later.
[1:26] Now, Codex is currently leading
in many of the different benchmarks out there.
[1:29] It can actually run faster than cloud code
and more importantly,
[1:32] is significantly cheaper to use,
especially on a subscription basis.
[1:36] In terms of the usage that you get, it's
practically unlimited if you're not running it,
[1:40] you know, in 20 different sessions, 24 seven.
[1:43] So I promise we'll get into the set up.
[1:44] But I just want to emphasize why this is worth doing.
[1:47] Now, if you're going to run a coding agent
on your own computer, you're going to run,
[1:50] you know, like cloud code or codex CLI
or just Codex or whatever.
[1:54] You do need your computer to be open, and that's
because it's using your local execution environment
[1:59] or your compute to actually run a terminal command
or modify a file or whatever it is that's going on,
[2:04] then this is fine in many situations
when you're actually going to be actively
[2:07] on the computer, you're working on something,
you're working with it kind of turn by turn,
[2:11] and every prompt you give is taking,
you know, maximum a few minutes.
[2:14] However, if you want to do a task
that's going to take eight hours,
[2:17] or you want to run a task every day
at a certain time, or you just want something to run
[2:21] for a super long period of time,
but you're not able to actually
[2:24] have your computer open,
or it needs to be in your backpack or whatever.
[2:27] Obviously, this doesn't work,
and even if you could run it on your laptop,
[2:31] if you lose internet, if you do this battery,
if you close it,
[2:34] if for some reason it turns off or restarts
or goes to sleep or whatever,
[2:37] you're going to lose all of that progress,
which obviously is very inconvenient.
[2:41] So the solution here is to have a VPN or virtual
[2:45] private server
where you can delegate long running tasks.
[2:48] It doesn't mean you're not going to run stuff
locally on your own computer
[2:51] when you want to do something,
and you need to close the lid of your laptop,
[2:53] or you know that it's not going to be available
for the next eight, ten, 24 hours.
[2:57] Whatever you delegated to the VP.
[2:59] So the basic idea is, in this video,
I'm going to show you how to spin up a VPNs,
[3:03] how to install codecs, CLI on it and authenticate
with your existing subscription,
[3:07] and then how you can control it from your phone
or from your laptop however you want to do it.
[3:11] You can delegate those long running tasks
and have everything
[3:15] handled securely,
privately on that virtual private server.
[3:18] This way, any time you need something
that's going to take a few hours,
[3:21] you want to run something on a schedule,
[3:22] do it all the VPNs and then the active work
you do on your own computers.
[3:25] You separate things out.
[3:27] Now there's three main reasons why this works.
[3:29] First, a virtual private server doesn't go to sleep.
[3:31] It's available 24 over seven in a secure environment
with a hard wired connection to the internet.
[3:36] Just doesn't go out.
[3:37] You keep all of the data
because you're self-hosting everything,
[3:40] and you can keep everything in a secure environment.
[3:42] And importantly, you also have data center speeds.
[3:44] So if you're going to be in a low
internet environment, which I know I am a lot
[3:48] when I'm traveling,
you can just use the virtual private server
[3:51] and get significantly faster speeds
for downloading something, uploading something,
[3:54] getting a data set, training a model,
whatever it is that you need to do.
[3:57] So anyways, that is kind of the quick brief here
and why this is worth setting up.
[4:01] Now let me show you exactly how to do it.
[4:04] Now, the first thing we're going to need
here is a virtual private server or VPN.
[4:07] But you can get any that you want.
[4:09] But for this video, I'm going to be using Hostinger
because they have some of the best virtual private
[4:13] servers on the market.
[4:14] They're the most reliable
and they're a long term partner of this channel.
[4:17] Meaning I can give you guys an additional discount.
[4:19] So I would recommend going with the KVM two plan
if you want to follow along with me.
[4:23] Here you can see all of the options they have.
[4:25] I'll leave a link to this in the description.
[4:27] I'm going to go with KVM two.
[4:29] And then from here what I'm going to do
is deploy and provision my virtual private server.
[4:32] Now because I have a partnership with Hostinger.
[4:34] If you go here and apply to code tech with Tim,
you'll get an additional 10% off as long as you're
[4:38] using a 12 month or 24 month subscription plan here,
which gives you a massive discount.
[4:42] So regardless, pick your plan, pick the duration
of what you want, apply the discount code.
[4:46] You can choose the region
that you want to have this applied
[4:48] in my case, Indonesia,
because that's where I'm located right now.
[4:51] And then you can choose OpenAI Codex,
where it's automatically going to deploy this
[4:55] and install some of the dependencies for you,
which will save you a lot of time.
[4:58] Hostinger also has a lot of other one
click deployments if you want to have a look at them.
[5:02] But of course for this video we need Codex,
so we'll apply that and then go ahead and press on.
[5:06] Continue.
[5:07] Now if you're following along with me here, it may
ask you to generate a root password for the server.
[5:11] If it does that you can just generate a random one
and then copy it.
[5:14] Obviously save it
and make sure you don't leak any anyone else.
[5:17] I will delete this server afterwards.
[5:18] So I'm going to go ahead and press on.
[5:20] Next I'm going to add the malware scanner
because it's free and obviously just a good idea
[5:24] to have on the VPNs and then press finish.
[5:26] And it's going to take a minute
or two here to provision the VPNs.
[5:29] Once it's done, I'll be right back.
[5:30] I'll show you how we can connect to it,
and then we can proceed to the next step.
[5:33] Okay.
[5:34] So MVP's is now deployed,
[5:36] and what I can do is go to the dashboard here
to view all of the different controls.
[5:40] And you can see that I have Codex deployed.
[5:42] Now at this point I'm going to assume
that you have some virtual private server.
[5:45] Whether you're using hosting or not,
it doesn't really matter.
[5:47] What we're going to need to do,
though, is find the IP address of our server
[5:51] so we can SSH into it and start configuring
a few things before we connect it to our phone.
[5:55] And before we start setting up scheduled tasks,
all of that kind of stuff.
[5:59] So what I'm going to do is just copy this right here,
the SSH command under root access.
[6:03] And also
make sure you have your root password from before.
[6:06] If you forgot it you can change it right here.
[6:08] And what I'm going to do is open up a terminal.
[6:10] So you can see
I've got a terminal open on my computer.
[6:12] Here.
[6:12] Let me just clear this
and make it a little bit larger.
[6:15] So you guys can see it.
[6:16] And we're going to paste the command ssh root at.
[6:19] And then the IP address of our server.
[6:21] Again if you're using a different provider
make sure you get the IP address.
[6:25] You get the username which is typically root.
[6:27] And then you know the password for signing it.
[6:29] So let's go ahead and press on enter.
[6:31] We're going to go yes.
[6:32] And just say okay we can connect to this host.
[6:34] And then we're going to paste in our password.
[6:37] When you paste the password
you won't see anything here.
[6:39] It will be invisible.
[6:40] So just paste it and then press enter okay.
[6:42] So you can see that
are now signed into my virtual private server.
[6:45] You'll see that if you see root add
and then some name here.
[6:48] In this case it's SRB that just would host or name.
[6:51] So now what we need to do is just verify
the codex is installed.
[6:54] If it's not I'll show you how to install it.
[6:55] In case you didn't use the one click
to play from Hostinger, we're then going to need
[6:58] to sign in with our accounts
that we can start using our existing subscription,
[7:03] or we can use an API key if we want,
but that's going to be quite expensive.
[7:06] Then after that, I'm going to show you a few quick
setup steps just to make this work really well.
[7:11] Then we're going to connect it
so we can trigger it from our phone.
[7:13] And I'll show you overall how this works.
[7:15] Automations all of that kind of fun stuff okay.
[7:17] So first things first
you can attempt to run the Codex command.
[7:21] Now again, if you use the one click
install option from Hostinger,
[7:24] it should automatically be installed for you.
[7:26] But if it's not, what you're going to want to do
is the following.
[7:28] I'll leave this link in the description.
[7:30] It's just the docs from Codex,
and you'll see that there is a setup command here.
[7:34] So there's a curl.
[7:35] You can just copy this, paste this
as the command and run it.
[7:39] And that will install the Codex CLI for you.
[7:42] Once it's installed you may need to just reconnect
to the server again so that your path updates,
[7:47] because sometimes the path variable
needs a second to refresh.
[7:50] I'm not going to talk about that too much in depth,
[7:52] but if you install it in the codex
command doesn't work, then just refresh the terminal.
[7:55] So just close it and re ssh back in
and it should work.
[7:58] So from here
we should be able to trigger the codex command.
[8:01] From here
we're going to go to sign in with device code.
[8:04] Or if you have your own API key you can use this.
[8:06] But it's probably going to be better
to use your existing ChatGPT subscription.
[8:10] So I'm gonna go sign in with device code.
[8:11] And what it's going to say is go to this link okay.
[8:14] So we're going to copy this
and just paste it in our browser.
[8:17] And then we're going to paste this code
right here from the terminal.
[8:20] So let's copy this.
[8:21] Go back okay.
[8:22] We're use my email here
and we're going to paste this device code.
[8:26] And that should allow us to be signed in case
what to paste this and press on continue okay.
[8:31] So from here it says that we're signed in now
and we can go ahead and press on.
[8:35] Enter from here. We're just going to go.
[8:37] Yes. Continue. That's fine.
[8:38] And you'll see that we've now opened up Codex
and we're able to start triggering something
[8:42] so we can say, you know, hello world
and it will start giving us some input.
[8:46] Now I'm not going to give you a full tutorial
on how Codex works here.
[8:48] There's a lot of different slash commands
that you can use.
[8:51] I'd recommend triggering the fast mode here.
[8:53] Even though it's going to use more usage.
[8:55] It's going to run a lot faster,
and if we keep going, you can see
[8:58] there's a lot of other stuff that you can run
and that you can do.
[9:02] Okay, so Codex is now working.
[9:03] We have it running on our computer if we want to exit
out of this, we can hit control C on our keyboard.
[9:09] That should quit out of Codex.
[9:11] And we can type clear just to clear
whatever is in the terminal.
[9:13] So we can have kind of a fresh screen.
[9:15] Now what I want to do next is I want to show
you just how to connect to GitHub,
[9:19] because it's going to be very useful
to have Codex connected to GitHub
[9:22] so that it can create repositories
for us, do pull requests, trigger automations, etc..
[9:27] So if you don't already, I would suggest
that you create a free GitHub account.
[9:32] You can do that just by going to GitHub.com.
[9:33] You don't need to pay for anything.
[9:35] And then what we're going to do is the following.
[9:37] So first we're going to go to our little avatar here.
[9:40] And we're going to go to settings.
[9:41] Now from settings we're going to scroll
all the way down to our developer settings.
[9:45] And we're going to create an API key that we can use
[9:48] in our virtual private server
to connect to our GitHub account.
[9:52] You can actually even give Codex
its own GitHub account
[9:54] if you want, but I like to connect it to mine
and just restrict the access that it has.
[9:58] So what I'm going to do is go to personal access
tokens here
[10:01] and go to fine
grained tokens from fine grained tokens.
[10:04] I'm going to go create new token.
[10:06] And what I'm going to do here is just name this.
[10:08] What are we doing here? You know, Codex.
[10:11] Okay.
[10:12] For the exploration, I'm just going to go.
[10:13] No exploration, so we don't need to change it.
[10:15] I'm going to go all repositories
so it can access all of my repositories.
[10:19] And I'm going to start setting the permissions
that I want Codex to have.
[10:22] Now, if I want this to have the ability
[10:24] to create and delete repositories,
I need to trigger administration.
[10:27] And if I want it to be able to edit
contents of the repository.
[10:30] So make a commit or view it.
[10:32] I need to add contents.
[10:34] Also, I want it to be able to make pull requests.
[10:35] I need to add pull request.
[10:37] So there's a lot of things here.
[10:37] But for most of you, you're
probably just going to need these. Now.
[10:41] For all of these,
I would suggest you go read and write again.
[10:44] Be careful.
[10:45] But what this is going to do
[10:45] is allow it to create a read delete
whatever repositories contents same thing.
[10:50] This will allow it to create content,
make branches, etc.
[10:54] and then for pull requests this will allow it to pull
related comments, assign it, etc..
[10:58] Now this is one you might want to be careful with
because if you put it to read and write,
[11:01] it can delete repos.
[11:02] So if you just want to test it to start,
make this read only, which I will do right now.
[11:06] But if you want it to be able
[11:07] to make new repos for you and stuff,
then you would have to go to read and write.
[11:11] Okay, so from here we're going to generate token,
but we're going to do that in one second
[11:15] after we install a tool called
g h in our virtual private server.
[11:19] This is essentially a GitHub tool that Codex
will be able to use to do GitHub related commands.
[11:25] Let me show you how it works.
[11:26] Okay, so from our terminal we're going
to run the command API to install g h dash y.
[11:31] Okay. So exactly like I have on screen.
[11:33] And go ahead and press on enter.
[11:35] It's going to install g h which is GitHub effectively
which will take a second.
[11:39] If we want to test if this is working we can run g h.
[11:42] Now after that we're going to type g h.
[11:44] And then I believe the command is not log in.
[11:46] It might be like okay, so start
[11:49] off and then log in okay.
[11:52] And then what we're going to do
is authenticate with GitHub.
[11:54] So to do this we're going to press GitHub.com https.
[11:58] And then we're going to use our git credentials okay.
[12:00] And we're going to paste in authentication token.
[12:02] So then what we're going to do is go back here.
[12:04] We're going to generate this token.
[12:06] Make sure you don't share it with anyone.
[12:07] And we're just going to paste it inside of here okay.
[12:09] So we're going to paste our authentication token
that we just generated from the previous step.
[12:13] Now you'll see it's logged in.
[12:14] You can see I'm logged in as tech with Tim.
[12:16] So now that I'm logged in my Codex should have
the ability to actually do things related to GitHub.
[12:21] And if we just want to test
that we can type code like this.
[12:25] And we can just tell it,
we can say, hey, you have access to the g
[12:28] h command
and you want to use the username tech with Tim.
[12:32] Can you just tell me a few repos
that you have access to?
[12:34] Just to verify that the GitHub command is working?
[12:38] And by the way,
[12:38] if you're wondering what I'm using to dictate here,
I'm using a really cool tool called Whisper Flow.
[12:42] It's free to use.
[12:43] I have a long term partnership with them,
so I'll leave a link to it.
[12:45] In the description
you can see I am an absolute power user
[12:48] and is the best voice dictation
or AI voice dictation.
[12:51] It actually has some really cool insights now
where you could see exactly where you're using it.
[12:54] The streaks. Very cool, very good.
[12:56] And you can see that I can speak at 260 words
per minute
[13:00] as opposed to my normal typing speed,
which is a lot slower than that.
[13:03] So anyways, I'm going to go ahead and press
[13:04] on, enter here, and it's just going to go
and try to use this command.
[13:08] And let's make sure that it works okay.
[13:10] So you can see that it's giving me
a whole list of repos here that it has access
[13:14] to private and public, which means this is working
and GitHub is now installed active.
[13:19] And we can move on to the next step. Okay.
[13:21] So the next thing we're going to do is trigger
this from our phone, which means we'll essentially
[13:25] just be able to control the virtual private server
and use Codex CLI from our mobile device.
[13:30] And I'm going to walk you through how to do that.
[13:32] Now the first thing we need to do here is install
a tool called tmux or tmux.
[13:37] What this is going to allow us to do
is persist in SSH session,
[13:41] even when we're not connected
to the virtual private server.
[13:44] The reason why we're going to need this tool,
we need to run this command that I have right here
[13:48] is because if we connect
to the virtual private server and we do something,
[13:51] so we say, hey Codex, go do this thing, run CLI,
and then we close the terminal by default,
[13:57] whatever was happening is going to be kind of quit
out of or it's going to be, you know, stopped.
[14:01] Right.
[14:01] So what tmux will allow us to do is run
what's called a persistent session.
[14:05] So even if we disconnect and we're not currently
on the virtual private server,
[14:09] whatever we're doing
will keep running in the background,
[14:12] which is super important
and kind of the whole point of this video.
[14:14] So we're just going to install tmux like this
apt install tmux dash one.
[14:18] I'm going to quickly show you 2 or 3 commands
that you need to be aware of.
[14:21] And then I'm going to show you how we can set this up
from our phone, which is really easy.
[14:25] So once you have tmux installed
you should be able to run tmux like this.
[14:28] Okay.
[14:29] Now when you just run tmux,
let me just exit out of this by typing exit.
[14:34] What it's going to do
is bring you into one of those persistent shells.
[14:37] Now, if we want to view all of the shells that are
currently active with tmux, we can type tmux ls.
[14:42] We can see nothing is running right now
because I had started a shell.
[14:45] But then I exit out of it,
which by default is going to close it.
[14:48] Now what we can do instead though is we can run tmux
new dash s, and then we can give this shell a name.
[14:54] So in this case I'm going to call it codecs.
[14:56] Then when we do this is going to bring us again
into a new team shell.
[15:00] Here we can run anything that we want
so we can run for example, codecs like this.
[15:04] And let's just say hello world.
[15:06] And now what I'm going to show you
is that if I close this
[15:08] virtual private server session
and then try to re kind of enter into it,
[15:12] I can get back into the shell
without having any of this information lost.
[15:16] So let me show you what I mean.
I'm just going to quit out of my terminal.
[15:19] Let's reopen the terminal and re ssh back in.
[15:22] Okay. Let me just get the password.
[15:24] Okay.
And from here, what I can do now is type tmux ls.
[15:27] You can see the codecs is still running.
[15:30] And then what I can do is type tmux attach.
[15:32] If I just type tmux attach by default it's
going to attach
[15:35] to the most recent shell which is going to be codecs.
[15:39] Now if I want to attach to a particular shell
[15:40] because you can have multiple running
that I can do dash t sorry.
[15:44] And then codecs.
[15:45] And what this is going to do
now is bring me back into that shell.
[15:48] Now again, if you're not super familiar
with virtual private servers,
[15:51] you may not know why this is important, but
this again allows us to have this persistent shell
[15:55] so that it can be stored
and running in the background no matter what.
[15:58] Okay, so for now, we're going to leave this shell
[16:00] running on my computer
and we're going to move over to our mobile device.
[16:03] So I'm going to show you how we can
now connect to the virtual private server.
[16:06] So we can trigger
tasks on the go from our phone. Okay.
[16:09] So from our phone here,
[16:10] what we're going to do is go to the App Store
and we need to download what's called an SSH client.
[16:14] Now you can use anything that you want.
[16:15] But the app that I'm going to recommend
here is called terminus okay says modern SSH client.
[16:21] It's free.
[16:21] You don't need to pay for anything,
but you need some kind of SSH client.
[16:25] You can do this on Android.
Maybe they have the same app.
[16:27] If not, you're just looking for any SSH client.
[16:30] Okay, so what we're going to do is just open up
this application.
[16:33] And effectively what we're going to do
is just go and sign in to our virtual private server
[16:38] from our phone.
[16:39] So what I can do here is press on the plus button,
I can go new host
[16:43] and I can start putting in this information.
[16:45] Now for the label I'm just going to call this codecs
[16:48] okay CLI
[16:49] for the IP or hostname, I'm going to use the same one
that I was using on my computer.
[16:53] So that's 187.77.121.81.
[16:59] If you're wondering how do you find this hostname?
[17:01] You can see it up here on my computer.
[17:02] I'll hopefully have this on the screen as well.
[17:04] It's the same thing
that we're ssh ING into from our computer.
[17:07] And if you go back to hostinger,
you can actually see it right here
[17:10] or from wherever you deployed
your virtual private server.
[17:13] If we keep going, what we'll be able to do
is use credentials so we can set our username.
[17:17] This is going to be root.
[17:19] And then the password is going to be
[17:20] the same password that you used previously
as the root password for the server.
[17:23] Okay. So I've got all of those details in.
[17:25] There's not really anything else
that we need to do here.
[17:28] We can just go ahead and press on enter
and then wait a second here.
[17:32] And it should start connecting
to this server foreign.
[17:34] So if I press on it now it's going to say
hey do you want to trust this device I'm going to go
[17:38] yes I do want to trust this.
[17:40] And then it's going to bring me right
in to my server.
[17:43] Now from here,
if we want to change what this looks like,
[17:45] you can see in this app
there's a little button so I can change.
[17:48] Like, do I want it to be light.
[17:49] Do I want it to be dark?
[17:50] I think it's going to be easier for you guys
to read it in kind of this light mode here, this
[17:54] yellow color theme.
[17:55] And we can make the text size larger as well.
[17:59] One second.
[18:00] Let me move this here. Okay.
So that's pretty much it.
[18:03] You can set, you know, how you want it to look.
[18:05] And then from here you can type anything
just like you would if you were on your computer.
[18:09] So what we want to do now is
we want to attach to that tmux
[18:12] session that we were running here
so that we can start using codecs.
[18:15] And if we don't have an existing session,
we should just make a new one.
[18:18] So that again, if we disconnect and reconnect,
we're not going to lose that task.
[18:22] So what we can do is type tmux.
[18:23] And then same thing. Last,
[18:25] if we want to view what we have running we can see
that we have codecs and it's currently attached.
[18:29] So I can do tmux okay.
[18:30] And then I'm going to go attach like that
[18:33] dash t and then codecs like so.
[18:37] And you'll see that I'm now inside of here.
[18:38] It's kind of glitching out on my computer
because we call it I'm connected on my phone.
[18:43] But you can see that if I type hello or something,
it's appearing on my computer as well as on my phone.
[18:48] Now, I know it looks a little bit weird,
[18:49] and that's just because we're attached
from two sessions at the same time.
[18:52] But you can see now that I can trigger a task,
I can ask it to write code.
[18:55] I can get it to do something from my mobile device.
[18:58] And then again, importantly,
if I like closed the session here on my computer
[19:02] and I go back to my phone, you can see
[19:04] it's still running and it's still going to be able
to execute the various tasks.
[19:08] And then again, if we quit out of this.
[19:09] So let's get out of our session and let's go back in.
[19:11] You can see that it will bring us back here.
[19:13] And then if I want to just completely close
out of this, I can press on it, press close.
[19:18] And then if I reconnect here.
[19:20] So give this a second to reconnect.
[19:21] Same thing we can do tmux
[19:24] and then attach.
[19:25] And then we'll be back in the codec session where
we can start asking you to do anything that we want.
[19:30] And I'm going to change the color theme here.
[19:31] So it's a little bit easier to read 
because it looks like it's like messing up here okay.
[19:35] So this one looks good.
[19:36] And then we can start triggering various tasks.
[19:39] So just give you an example of something we can do
here.
[19:41] I'm just going to paste in a URL.
[19:43] This is one of the GitHub repos I have access to.
[19:46] And I'm just going to say
hey can you review all paths in this repo?
[19:53] And I know I'm kind of spelling some of this wrong,
but that should be fine.
[19:55] And let's go ahead and press on, enter and let's
see if I can go and review this for us okay.
[20:00] So you can see that
it's reviewing all of the PR right now.
[20:02] It's giving me all of the responses and saying which
one should be approved, should it be approved, etc..
[20:07] And now we're good to go.
[20:08] And the same thing.
[20:08] We could close it, reopen it, go on our laptop,
you get the idea.
[20:11] Now where this is going to become super
useful is actually when we start running automation.
[20:16] So I want to show you that
now I'm going to go back to the computer.
[20:19] But keep in mind
everything that I do on the computer,
[20:21] you could do it from your phone as well.
[20:22] It's just easier for
you guys to see on a bigger screen.
[20:24] Okay, so I'm back on the computer.
[20:26] You can see I've reattached to the team like session
[20:28] where we are running from our phone,
and now we can continue working.
[20:31] Now, like I mentioned,
I want to talk about automations.
[20:33] Automations are just things
that can run on a particular schedule.
[20:36] Now, unlike Cloud Code, Codex doesn't have any built
[20:40] in kind of scheduling feature, although I'm sure
they're probably going to add that in the future.
[20:43] But if we want to set that up to run on our VPS, it's
very easy and we can create something
[20:48] called a cron job, which is a huge advantage
of having this virtual private server.
[20:52] Now, effectively,
all we have to do is just tell Codex
[20:55] to do this for us and say, hey, every day
I want you to do X, y, z.
[21:00] Maybe
[21:00] I want you to review all of the code in my code base
and tell me if there's any security vulnerabilities.
[21:05] Maybe I want you to review all of the PR
and automatically reject or approve.
[21:08] Maybe I want you to write a change log of anything
that's occurred in this repo.
[21:12] Maybe I want you to update all of the Readme files.
[21:14] Whatever. Okay.
[21:15] So what I'm going to do is just define
I'm going to say
[21:18] I want to set up a simple automation
that runs every single day using the Codex clock.
[21:23] I need you to create a cron job.
[21:25] This is the key term that you want to keep in mind
by the way.
[21:27] Cron job
because that's what you want it to ask it to do.
[21:30] That runs correctly on the repo
[21:33] that I just sent you above and reviews all of the PR
and then creates a markdown file that's uploaded
[21:39] to the repository that includes the status of this PR
and if they should be approved or not.
[21:45] This is a silly automation.
[21:46] Like it doesn't really make sense to run this,
but I'm just giving you an example of something
[21:49] you could do.
[21:50] I'm saying, hey, set up an automation to use Codex
cli way to create this cron job and execute this.
[21:55] Now the way that this is going to work
is there's this command called Codex exac.
[22:00] And if you run this, it's
going to not bring you into a codex session,
[22:04] but it will just execute whatever you ask it to do.
[22:07] So I can say Codex Exec and then like do this thing
and it will just execute it and do it
[22:12] so we can set up a cron job that will do that for us.
[22:15] And I'm just going to go, yes.
[22:16] And don't ask for these commands
because it's asking us to approve this.
[22:19] So effectively what it's going to do is say hey
on this schedule, it's going to be set up on
[22:23] what's called a cron job,
which can run on kind of an automated timing run,
[22:27] Codex Exec, which is going to trigger
this thing to happen right where Codex CLI
[22:32] is going to go and run this task and then complete
whatever it is that we asked it to do.
[22:36] So you can see that it's currently creating this cron
job which is putting under a crontab.
[22:40] It asks me just to approve the command, which I did.
[22:42] And you can see now that the entry is installed
and it's going to start running this process.
[22:46] So we're just going to tell it okay, run this.
[22:48] And again the advantage of the VP is
you're in an isolated environment.
[22:51] So it's not going to mess up your own computer.
[22:53] If it actually makes a mistake
you can always shut it down.
[22:55] It's not a huge deal.
[22:56] So just running all of these cron the
terminal commands for us and it should set this up.
[23:01] And then we will have that automation
running every single day okay.
[23:05] So just doing a dry run now
to make sure this is going to work.
[23:08] I'm not going to bore
you guys and go through this whole process.
[23:10] I just wanted to show you that setting up
these automations is a good way to really
[23:14] utilize this service
and have it running in the background,
[23:17] even when you're not manually triggering
tasks to execute.
[23:20] And again, the reason
[23:21] why you want something like this is that if you want
something that's going to take a long time to run,
[23:25] you just delegated to the VPCs
and you don't rely on you having a computer open.
[23:29] Again. You could set up all these automations.
[23:31] You can have a trigger, you can set up, you know,
MCP servers, and you can do really cool stuff using
[23:35] Codex CLI, which is currently kind of the leading
agent and harness for coding related tasks.
[23:41] So that's it guys.
I'm going to wrap up the video here.
