vSphere Air-gapped: Load the Registry

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

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

1. Download dkp-air-gapped-bundle_v2.6.2_linux_amd64.tar.gz , and extract the tarball to a local directory:

   CODE

   tar -xzvf dkp-air-gapped-bundle_v2.6.2_linux_amd64.tar.gz && cd dkp-v2.6.2

2. Set an environment variable with your registry address using this command:

   CODE

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

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

   CODE

   dkp push bundle --bundle ./container-images/konvoy-image-bundle-v2.6.2.tar --to-registry $REGISTRY_ADDRESS --to-registry-username $REGISTRY_USERNAME --to-registry-password $REGISTRY_PASSWORD

   NOTE: To use ECR, set an environment variable with your registry address for ECR:

   CODE

   export REGISTRY_URL=<ecr-registry-URI>

   • REGISTRY_URL: the address of an existing local registry accessible in the VPC that the new cluster nodes will be configured to use a mirror registry when pulling images.

   • The environment where you are running the dkp push command must be authenticated with AWS in order to load your images into ECR.

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.

Kommander Load Images

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.

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-v2.6.2.tar --to-registry $REGISTRY_ADDRESS

Load Images to your Private Registry - DKP Catalog Applications

Optional: This step is required only if you have an Enterprise license.

For DKP Catalog Applications, also perform this image load:

Run the following command to load the dkp-catalog-applications image bundle into your private registry:

dkp push bundle --bundle ./container-images/dkp-catalog-applications-image-bundle-v2.6.2.tar --to-registry $REGISTRY_ADDRESS
