vSphere Air-gapped Seed Docker Registry

Seed your docker registry

Before creating a Kubernetes cluster, you need the required images in a local docker registry. This registry must be accessible from both the bastion machine and the other machines that will be created for the Kubernetes cluster.

1. Assuming you have downloaded dkp-air-gapped-bundle_v2.4.1_linux_amd64.tar.gz , extract the tarball to a local directory:

   CODE

   tar -xzvf dkp-air-gapped-bundle_v2.4.1_linux_amd64.tar.gz && cd dkp-v2.4.1

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

   CODE

   export DOCKER_REGISTRY_ADDRESS=<registry-address>:<registry-port>
   export DOCKER_REGISTRY_USERNAME=<username>
   export DOCKER_REGISTRY_PASSWORD=<password>

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

   CODE

   dkp push image-bundle --image-bundle ./container-images/konvoy-image-bundle-v2.4.1.tar --to-registry $DOCKER_REGISTRY_ADDRESS --to-registry-username $DOCKER_REGISTRY_USERNAME --to-registry-password $DOCKER_REGISTRY_PASSWORD

Next Step:

Once you have seeded your registry, you begin the cluster building process by Creating the Bootstrap cluster.
