Using kubectl and helm with Rockoon AIO#

To configure and manage Rockoon AIO, you need the kubectl and helm command-line tools. These tools are already installed on your Rockoon AIO instance, but you can also install them locally on your computer.

  1. Install kubectl and helm locally. Follow the official installation instructions:

  2. Retrieve the configuration file from the Rockoon AIO instance.
    The kubeconfig file for Rockoon AIO is located on the instance at /root/.kube/config. You can retrieve it over SSH. For Linux/macOS, run: 

    ssh -l ubuntu 18.218.29.107 sudo cat /root/.kube/config > ~/aio_kube_config.yaml
    In this example:

    • 18.218.29.107 is the public IPv4 address of your Rockoon AIO instance.
    • The file is saved locally as aio_kube_config.yaml in your home directory.

  3. Use kubectl and helm with the configuration file
    When connected to the Rockoon AIO instance via sshuttle or OpenVPN, you can run commands like: 

    kubectl --kubeconfig ~/aio_kube_config.yaml ...
helm --kubeconfig ~/aio_kube_config.yaml ...

    Note: If you want to avoid specifying --kubeconfig each time, move the configuration file to ~/.kube/config.
    Warning: This will overwrite existing Kubernetes configuration file at that location.

  4. Handling self-signed SSL certificates for TryMOSK installation
    TryMOSK uses a self-signed SSL certificate for its proxy-server. If running helm commands from your local computer, you must add --insecure-skip-tls-verify flag to skip TLS verification.
