Installation

Most easily, the installation can be performed by 23kectl, a configuration wizard for a basic setup. It is recommended to start with a basic setup and tweak it afterwards to the desired behavior.

Basic Install Command​

Once your environment fulfills the prerequisites and you have 23kectl installed, you can start the installation:

export KUBECONFIG=KUBECONFIG_FOR_BASE_CLUSTER
23kectl install

This command will create a config.yaml file in the current directory which stores the configuration options collected by the wizard. If you do not want to export the KUBECONFIG variable and/or use another configuration file name you can also run 23kectl like so

23kectl install --kubeconfig KUBECONFIG_FOR_BASE_CLUSTER --config=another-config.yaml

After completing the wizard, you can watch the installation process in the cluster. Using kubectl, you can watch flux resources like helmreleases or kustomizations

kubectl get -n flux-system helmrelease --watch

or

kubectl get -n flux-system kustomization --watch

Once all helmreleases are in the "reconcile succeeded" state, the installation is complete.

tip

For further configuration, see the architecture and configuration. If you are interested in more sophisticated setups, have a look at the guides provided in this documentation.

Help Commands​

If you like to get some help on the command line you can invoke

23kectl install -h

However, you will find more comprehensive information in this documentation.

Troubleshooting​

If the installation process fails, i.e. helmreleases and/or kustomizations do not get into a healthy state, you should

  • Check the credentials in your config file. If you have a typo somewhere, correct it and run the install command again.
  • Check whether your cloud credentials such as the DNS provider credentials are allowed to perform the required actions. Also consult the Gardener documentation in that case.
  • Check which helmrelease fails and check the resources deployed by this helmrelease for events showing errors.

If none of these help, there could be an issue in your base infrastructure. In that case, contact us or file an issue. We're always happy to help.
