Essential: For Air-gapped Environments Only

If you are operating in an air-gapped environment, a local container registry containing all the necessary installation images, including the Kommander images is required. See below for how to push the necessary images to this registry.

  • Download the Complete DKP Air-gapped Bundle for this release (i.e. dkp-air-gapped-bundle_v2.6.0_linux_amd64.tar.gz)

  • Connectivity:

    • Your Essential cluster must be able to connect to the local registry.

Extract Air-gapped Images and Set Variables

Follow these steps to extract the air-gapped image bundles into your private registry:

  1. Assuming you have downloaded dkp-air-gapped-bundle_v2.6.1_linux_amd64.tar.gz , extract the tarball to a local directory:

    tar -xzvf dkp-air-gapped-bundle_v2.6.1_linux_amd64.tar.gz && cd dkp-v2.6.1
  2. Set an environment variable with your registry address:

    export REGISTRY_ADDRESS=<registry-address>:<registry-port>
    export REGISTRY_USERNAME=<username>
    export REGISTRY_PASSWORD=<password>

Load Images to your Private Registry - Kommander

Load Kommander images to your Private Registry

For the air-gapped kommander image bundle, run the command below:

Run the following command to load the image bundle:

dkp push bundle --bundle ./container-images/kommander-image-bundle-v2.6.1.tar --to-registry $REGISTRY_ADDRESS

Load Images to your Private Registry - Konvoy

Before creating or upgrading a Kubernetes cluster, you need to load the required images in a local registry if operating in an air-gapped environment. This registry must be accessible from both the bastion machine and either the AWS EC2 instances or other machines that will be created for the Kubernetes cluster.

If you do not already have a local registry set up, refer to Local Registry Tools page for more information.

Execute the following command to load the air-gapped image bundle into your private registry:

dkp push bundle --bundle ./container-images/konvoy-image-bundle-v2.6.1.tar --to-registry $REGISTRY_ADDRESS --to-registry-username $REGISTRY_USERNAME --to-registry-password $REGISTRY_PASSWORD

It may take some time 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 registry.
