How to Deploy From Github Actions to Digitalocean Kubernetes?

3 minutes read

To deploy from GitHub Actions to DigitalOcean Kubernetes, you first need to set up your Kubernetes cluster on DigitalOcean. Once your cluster is up and running, you can configure your GitHub repository to trigger a workflow when changes are made to the code.


In your GitHub repository, you can create a workflow file that defines the build and deployment process. This file will specify the steps to build and push the container image to a container registry, and then deploy the image to your Kubernetes cluster on DigitalOcean.


You will need to set up any necessary secrets or environment variables in your GitHub repository to securely access your Kubernetes cluster. These variables will include the Kubernetes cluster URL, authentication token, and any other credentials needed to deploy to your cluster.


Once your workflow file is configured and your secrets are set up, you can push your changes to your GitHub repository to trigger the workflow. The GitHub Actions pipeline will automatically build and deploy your application to your DigitalOcean Kubernetes cluster whenever changes are made to your codebase.


What is a Kubernetes ingress controller?

A Kubernetes Ingress controller is a Kubernetes resource that manages access to services within the cluster from outside the cluster. It acts as a traffic manager and routes incoming traffic to the appropriate services based on defined rules. Ingress controllers typically support features such as SSL termination, load balancing, and path-based routing.


How to set up a self-hosted GitHub Actions runner?

Setting up a self-hosted GitHub Actions runner involves the following steps:

  1. Create a new personal access token on GitHub: Go to your GitHub account settings Click on "Developer settings" from the left sidebar Click on "Personal access tokens" Click on "Generate new token" Select the appropriate permissions for the token (e.g. repo access) Click on "Generate token" and copy the token to a safe place
  2. Create a new repository for your self-hosted runner: Create a new GitHub repository where you will store the necessary files for your self-hosted runner
  3. Download the GitHub Actions self-hosted runner package: Go to the Actions tab in your GitHub repository Click on "New self-hosted runner" and follow the instructions to download the runner package for your operating system
  4. Configure the self-hosted runner: Unzip the downloaded runner package on your machine Run the configuration script and follow the instructions to register your runner with GitHub Use the personal access token generated in step 1 when prompted
  5. Start the self-hosted runner service: Once the runner is configured, start the runner service on your machine The runner should now be available to run workflows in your GitHub repository
  6. Test the self-hosted runner: Create a new workflow file in your GitHub repository that specifies the self-hosted runner Push the workflow file to trigger a workflow run using your self-hosted runner Check the Actions tab in your GitHub repository to see the status of the workflow run


That's it! You have now successfully set up and configured a self-hosted GitHub Actions runner.


What is a GitHub Actions runner?

A GitHub Actions runner is a virtual machine that can run workflows in response to GitHub events. It is responsible for carrying out the tasks defined in the workflow file, such as building and testing code, deploying applications, and running automated tasks. Runners can be hosted by GitHub (GitHub hosted runners) or can be self-hosted on your own infrastructure (self-hosted runners).
