Kommander in an Air-gapped Environment

Follow these steps to install the Kommander component of DKP Essential in an air-gapped environment with basic setup.

Installation

1. Create the configuration file by running dkp install kommander --init --airgapped > kommander.yaml for the air-gapped deployment.

2. In the same file, if you are installing Kommander in an AWS VPC, set the Traefik annotation to create an internal facing ELB by setting the following:

   apps:
     traefik:
       enabled: true
       values: |
         service:
           annotations:
             service.beta.kubernetes.io/aws-load-balancer-internal: "true"

   CODE

3. To install Kommander in your air-gapped environment using the above configuration file, enter the following command:

   dkp install kommander --installer-config kommander.yaml --kubeconfig=${CLUSTER_NAME}.conf \
   --kommander-applications-repository ./application-repositories/kommander-applications-v2.5.0.tar.gz \
   --charts-bundle ./application-charts/dkp-kommander-charts-bundle-v2.5.0.tar.gz 

   CODE

   In the previous command, the --kubeconfig=${CLUSTER_NAME}.conf flag ensures that you set the context to install Kommander on the right cluster. For alternatives and recommendations around setting your context, refer to Provide Context for Commands with a kubeconfig File.
   

   

   TIP: Sometimes, applications require a longer period of time to deploy, which causes the installation to time out. Add the --wait-timeout <time to wait> flag and specify a period of time (for example, 1h) to allocate more time to the deployment of applications.

Next Steps:
