Getting Started on Okteto Cloud with PHP

Okteto Cloud gives instant access to secure Kubernetes namespaces to enable developers to code, build, and run Kubernetes applications entirely in the cloud.

This tutorial will show you how to create an account in Okteto Cloud and how to develop a PHP sample application.


Step 1: Deploy the PHP Sample App#

Get a local version of the PHP Sample App by executing the following commands:

$ git clone
$ cd php-getting-started

The k8s.yml file contains the Kubernetes manifests of the PHP Sample App. Deploy a dev version of the application by executing:

$ kubectl apply -f k8s.yml
deployment.apps "hello-world" created
service "hello-world" created

Open your browser and go to the URL of the application. You can get the URL by logging into Okteto Cloud and clicking on the application's endpoint:

Did you notice that you're accessing your application through an HTTPS endpoint? This is because Okteto Cloud will automatically create them for you when you deploy your application. Cool no ๐Ÿ˜Ž?

Step 2: Create your okteto manifest#

To start developing on the PHP Sample App you first need to create an okteto manifest. With the PHP Sample App deployed, run the following command to create your okteto manifest:

$ okteto init
This command walks you through creating an okteto manifest.
It only covers the most common items, and tries to guess sensible defaults.
See for the official documentation about the okteto manifest.
Use the arrow keys to navigate: โ†“ โ†‘ โ†’ โ†
Select the deployment you want to develop:
โ–ธ hello-world
Use default values

The okteto init command will scan the available deployments in your Kubernetes namespace and ask you to pick one. Select the hello-world deployment. It's the one we deployed on the previous step.

โœ“ hello-world
โœ“ Deployment 'hello-world' successfully analyzed
โœ“ okteto manifest (okteto.yml) created
i Run 'okteto up' to activate your development container

The okteto init command creates the following okteto.yml file:

name: hello-world
command: bash
- /root/.composer/cache
- .:/app
- 8080:8080
- 9000:9000

This file defines how to activate a development container for the PHP Sample App:

  • name: the name of the Kubernetes deployment you want to put on development mode.
  • command: the start command of the development container.
  • volumes: a list of paths in your development container to be mounted as persistent volumes. For example, this is useful to persist the Composer cache.
  • sync: the folders that will be synchronized between your local machine and the development container.
  • forward: a list of ports to forward from your development container.
  • reverse: a list of ports to reverse forward from your development container to your local machine

Also, the okteto init command creates a .stignore file to indicate which files shouldn't be synchronized to your development container. This is useful to avoid synchronizing binaries, build artifacts, or git metadata.

Step 3: Activate your development container#

Next, execute the following command to activate your development container:

$ okteto up
โœ“ Persistent volume successfully attached
โœ“ Images successfully pulled
โœ“ Files synchronized
Namespace: cindy
Name: hello-world
Name: hello-world
Forward: 8080 -> 8080
Reverse: 9000 <- 9000
Welcome to your development container. Happy coding!
cindy:hello-world app>

Working in your development container is the same as working on your local machine. Start the application by running the following command:

cindy:hello-world app> php -S
[Tue Jan 7 01:54:59 2020] PHP 7.4.1 Development Server ( started

Go back to the browser, and reload the page to test that your application is running.

Step 4: Develop directly in Okteto Cloud#

Open the index.php file in your favorite local IDE and modify the response message on line 2 to be Hello world from the cluster!. Save your changes.

$message = "Hello World from the cluster!";

Go back to the browser and reload the page. Your code changes were instantly applied. No commit, build or push required ๐Ÿ˜Ž!

Step 4: Debug directly in Okteto Cloud#

Okteto enables you to debug your applications directly from your favorite IDE. Let's take a look at how that works with PHPStorm, one of the most popular IDEs for PHP development.

If you haven't already, fire up PHP Storm and load this project there. Once the project is loaded, open index.php and set a breakpoint in line 2. Click on the Start Listen PHP Debug Connections button on the PhpStorm toolbar.

Go back to your browser and reload the page. The execution will automatically halt at the breakpoint.

If this is the first time you debug this application, the IDE will ask you to confirm the source mapping configuration. Verify the values and click ok to continue.

At this point, you're able to inspect the request object, the current values of everything, the contents of $_SERVER variable, etc.

debugging in Okteto Cloud with PHP

Your code is executing in Okteto Cloud, but you can debug it from your local machine without any extra services or tools. Pretty cool no? ๐Ÿ˜‰

Next steps#

Congratulations, you just developed your first application in Okteto Cloud ๐Ÿš€.

Okteto lets you develop your applications directly in Kubernetes. This way you can:

  • Eliminate integration issues by developing in a realistic environment
  • Test your application end to end as fast as you type code
  • No more CPU cycles wasted in your machine. Develop at the speed of the cloud!

Okteto uses the okteto.yml file to determine the name of your development container, the docker image to use, and where to upload your code. Check the Okteto manifest docs to customize your development containers with your own dev tools, images, and dependencies to adapt Okteto to your own application.
