Using Multiple Containers in a Kubernetes Pod

Multi-container Pods in Kubernetes use additional containers within the same Pod to solve technical challenges. This lab will allow you to get hands-on with multi-container Pods. You will build expertise as you design your own multi-container Pod in order to address a real-world issue.

  1. Challenge

    Update the Service to Use the New Port

    There is a Service called hive-svc located in the default Namespace. Modify this service so that it listens on port 9076.

  2. Challenge

    Add an init Container to Delay Startup

    The app is managed by the app-gateway Deployment located in the default Namespace. Add an init container to the Pod template so that startup will be delayed by 10 seconds. You can do this by using the busybox:stable image and running the command sh -c sleep 10.

  3. Challenge

    Add an Ambassador Container to Make the App Use the New Service Port

    Find the app-gateway Deployment located in the default Namespace. Add an ambassador container to the Deployment's Pod template using the haproxy:2.4 image.

    Supply the ambassador container with an haproxy configuration file at /usr/local/etc/haproxy/haproxy.cfg. There is already a ConfigMap called haproxy-config in the default Namespace with a pre-configured haproxy.cfg file.

    You will need to edit the command of the main container so that it points to localhost instead of hive-svc.
