Install DKP in an Air-gapped Environment

How to run DKP using an Air-gapped installation

The following explains how to run DKP on top of an air-gapped DKP cluster installation.


Before installing, ensure you have:

  • A Docker registry containing all the necessary Docker installation images, including the Kommander images. The kommander-image-bundle.tar tarball has the required artifacts.

  • A charts bundle file containing all Helm charts that Kommander installation needs.

  • Connectivity with clusters attaching to the management cluster:

    • Both management and attached clusters must be able to connect to the Docker registry.

    • The management cluster must be able to connect to all attached cluster’s API servers.

    • The management cluster must be able to connect to any load balancers created for platform services on the management cluster.

  • A configuration file that you can adapt to your needs using the steps outlined in this topic. Make sure to create that file using the following command:

dkp install kommander --init --airgapped > install.yaml

Kommander Charts Bundle

The charts bundle is a gzipped Tar archive containing Helm charts, which are required during Kommander installation. Create the charts bundle with the DKP CLI or downloaded along with the DKP CLI. Execute this command to create the charts bundle:

dkp create chart-bundle

Kommander creates charts-bundle.tar.gz. Optionally, specify the output using the -o parameter:

dkp create chart-bundle -o [name of the output file]

Kommander Internal Helm Repository

The Kommander charts bundle is pushed to Kommander’s internal Helm repository. To inspect the contents:

dkp get charts

Individual charts can be removed using:

dkp delete chart [chartName] [chartVersion]

It is possible to push new charts as well:

dkp push chart [chartTarball]

Or push a new bundle:

dkp push chart-bundle [chartsTarball]

Check the built-in help text for each command for more information.

Load the Docker images into your Docker registry

  1. See the NOTICES.txt file for 3rd party software attributions and place the kommander-image-bundle-v2.3.3.tar bundle within a location where you can load and push the images to your private Docker registry.

  2. Run the following command to load the air-gapped image bundle into your private Docker registry:

    dkp push image-bundle --image-bundle kommander-image-bundle-v2.3.3.tar --to-registry <REGISTRY_URL>

It may take a while to push all the images to your image registry, depending on the performance of the network between the machine you are running the script on and the Docker registry.

  1. Create the configuration file by running dkp install kommander --init --airgapped > install.yaml for the air-gapped deployment. Open the install.yaml file and review that it looks like the following:

    kind: Installation
      enabled: true
  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:

        values: |
  3. Download the Kommander application definitions:

    wget ""
  4. Download the Kommander charts bundle:

    wget "" && tar -xvf dkp-kommander-charts-bundle-v2.3.3.tar.gz
  5. To install Kommander in your air-gapped environment using the above configuration file, enter the following command:

    dkp install kommander --installer-config ./install.yaml \
    --kommander-applications-repository kommander-applications-v2.3.3.tar.gz \
    --charts-bundle dkp-kommander-charts-bundle-v2.3.3.tar.gz
  6. When completed, you can verify your installation.
