Add Kaptain to DKP Catalog Applications

Add Kaptain to DKP Catalog Applications in networked environments before deploying to clusters

Ensure that your kubectl configuration references the cluster on which you must execute the commands.

Ensure the cluster that you want to use to deploy Kaptain is the only cluster in its workspace. Kaptain is meant to be deployed on workspaces with a single cluster.

Requirements

For reference values of the required number of worker nodes, CPU, RAM, and storage resources, refer to the requirements section.

Prerequisites

Ensure you have reviewed and executed all steps in the prerequisites section.

Create a Git repository for Kaptain

Make Kaptain available for deployment by creating a Git Repository. Use the CLI to create the GitRepository resource and add a new repository.

Refer to air-gapped for DKP 2.2 and later installation instructions, if you are deploying in an air-gapped environment.

1. Ensure your clusterKubeconfig.conf is set to your Essential or Management cluster, depending on your license.

2. Add the Flux GitRepository to your Kommander install:

   CODE

   cat <<EOF | kubectl apply -f -
   apiVersion: source.toolkit.fluxcd.io/v1beta1
   kind: GitRepository
   metadata:
     name: kaptain-catalog-applications
     namespace: kommander
     labels:
       kommander.d2iq.io/gitrepository-type: catalog
       kommander.d2iq.io/gitapps-gitrepository-type: dkp
       kommander.d2iq.io/workspace-default-catalog-repository: "true"
   spec:
     interval: 1m0s
     ref:
       tag: v2.2.0
     timeout: 20s
     url: https://github.com/mesosphere/kaptain-catalog-applications
   EOF

3. Ensure the status of the GitRepository signals a ready state:

   CODE

   kubectl get gitrepository kaptain-catalog-applications -n kommander

   The repository commit displays the ready state:

   CODE

   NAME         URL                                                        READY   STATUS                                                              AGE
