Passing Configuration Data to a Kubernetes Container

Kubernetes has multiple options for storing and managing configuration data. This lab will focus on the process of passing that configuration data to your containers in order to configure applications. You will have the opportunity to work with application configuration in Kubernetes hands-on by passing some existing configuration data stored in Secrets and ConfigMaps to a container.

  1. Challenge

    Generate an `htpasswd` File and Store It as a Secret

    Use htpasswd to generate an htpasswd file.

    Create a secret called nginx-htpasswd, and store the contents of the htpasswd file in that Secret. Delete the htpasswd file once the Secret is created.

  2. Challenge

    Create the Nginx Pod

    Create a pod with a single container using the nginx:1.19.1 image.

    The Nginx configuration is stored in an existing ConfigMap called nginx-config. Mount the ConfigMap to /etc/nginx in your pod.

    Mount your htpasswd secret to /etc/nginx/conf within your pod. The htpasswd data should be in a file in the container at /etc/nginx/conf/.htpasswd.

    Expose containerPort 80 on the Nginx container so you can communicate with it to test your setup.
