  1. Challenge

    Create a GitHub Personal Access Token

    To bootstrap the repository, you can use a GitHub Personal Access Token (PAT) to authenticate with GitHub. The PAT will need repo permissions.

    Hint: You can create a PAT on github.com. Select the account dropdown at the top right, then Settings > Developer settings > ((Personal access tokens** > Generate new token. Check the repo scope to provide the appropriate permissions.

    When you are done, copy the PAT. You will need it for the next objective!

  2. Challenge

    Bootstrap the Git Repository

    Bootstrap the GitHub repository with Flux. You will need to supply your GitHub username and the personal access token (PAT). You can use a repository name such as acg-flux-lab, but this can really be any name you want. Flux is already installed, so you do not need to install it.

    This process will create the repository in GitHub, so you may need to use a different name if you already have a repository by that name (such as if you go through this lab more than once).

    Hint: The command looks like this:

    flux bootstrap github --owner=<GitHub Username> --repository=acg-flux-lab --branch=main --path=./clusters/my-cluster --personal

  3. Challenge

    Create a Deployment via the GitHub Repository Using Flux

    Create a YAML file in the GitHub repository under clusters/my-cluster. Name this file turtle-deployment.yaml. Within the file, put a YAML manifest for a Deployment called turtle-deployment. Use the Deployment to run 3 replicas with the nginx:stable image.

    You can put the Deployment in the default namespace, but you will need to specify the namespace in the manifest with metadata.namespace.

    Commit the file, and after a few moments the Deployment should appear in your cluster!
