Canary Deployments with Kubernetes and Jenkins

Canary deployments are a great way to achieve greater stability when doing continuous deployments. By testing changes in a live environment with real users, you can deploy with greater confidence while minimizing the impact of bugs and issues on your users. In this learning activity, you will implement a simple canary deployment to a Kubernetes Cluster as part of a Jenkins Pipeline.

  1. Challenge

    Set up the project and Jenkins and run an initial deployment.

    To this, you will need to perform the following steps:

    1. Fork the sample source code repo:
    2. Change the DOCKER_IMAGE_NAME at the top of the Jenkinsfile to use your docker hub username instead of willbla.
    3. Log in to the Jenkins server.
    4. Set up the credentials in Jenkins (GitHub access token, Docker Hub, and Kubeconfig).
    5. Create a project and build it from your fork.
  2. Challenge

    Add a canary stage to the pipeline and run a successful deployment.

    To complete this, you will need to do the following:

    1. Create a deployment template for the canary deployment with a "canary" track.
    2. Add a canary stage to the Jenkinsfile to perform the canary deployment.
    3. Modify the production deploy stage to clean up the canary deployment after production deployment is approved.
    4. Execute the deployment in Jenkins.

    Don't hesitate to Refer to the example-solution branch of the sample source code repo for an example of how to do this!
