Use the docker build and docker push commands in your .gitlab-ci.yml file to automate this process.

Warning: For production environments, it’s crucial to secure your Kubernetes cluster. Restrict service account access to only push Docker images and create a separate account with the container-registry.images.pusher role for deployment.

Once your images are ready, configure kubectl to interact with your Kubernetes cluster. Here’s a basic script snippet for your CI pipeline:

deploy:
  image: gcr.io/cloud-builders/kubectl:latest
  stage: deploy
  script:
    - kubectl config set-cluster k8s --server="$KUBE_URL" --insecure-skip-tls-verify=true
    - kubectl config set-credentials admin --token="$KUBE_TOKEN"
    - kubectl config set-context default --cluster=k8s --user=admin

Remember to replace the placeholders with your actual cluster information. Automate deployments with GitLab to save time, ensure consistency, and streamline your DevOps workflow.

Running Scripts After Each Commit

Automating tasks after each commit can significantly streamline your development workflow. By configuring your .gitlab-ci.yml file, you can ensure that scripts are executed automatically, providing immediate feedback on the changes made. This automation is a cornerstone of the CI/CD process, allowing for continuous integration and deployment without manual intervention.

To set up scripts to run after each commit, follow these steps:

  1. Define the stages in your .gitlab-ci.yml file, such as build, test, and deploy.
  2. Under each stage, specify the script keyword followed by the commands you want to execute.
  3. Use conditional statements within the script to perform actions based on the commit message or other variables.

For example, to apply Kubernetes configurations:

stage: deploy
script:
  - kubectl config use-context ${CI_PROJECT_PATH}:<GitLab_Agent_name>
  - cat k8s.yaml | sed -e "s,__VERSION__,${CI_REGISTRY}/${CI_PROJECT_PATH}:${CI_COMMIT_SHORT_SHA}," | kubectl apply -f -

Remember to replace <GitLab_Agent_name> with the actual name of your GitLab agent in Managed Service for GitLab.

By leveraging the power of GitLab’s CI/CD features, you can create a robust pipeline that reacts to every commit, ensuring that your application is always in a deployable state.
