vSphere Air-gapped: Load the Registry

Before creating an air-gapped Kubernetes cluster, you need to load the required images in a local registry for the Konvoy component. 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. If not already done in prerequisites, download the air-gapped bundle dkp-air-gapped-bundle_v2.8.1_linux_amd64.tar.gz , and extract the tarball to a local directory:

   CODE

   tar -xzvf dkp-air-gapped-bundle_v2.8.1_linux_amd64.tar.gz

2. The directory structure after extraction can be accessed in subsequent steps using commands to access files from different directories. EX: For the bootstrap cluster, change your directory to the dkp-<version> directory similar to example below depending on your current location:

   CODE

   cd dkp-v2.8.1

3. Set an environment variable with your registry address and any other needed variables using this command:

   CODE

   export REGISTRY_URL="<https/http>://<registry-address>:<registry-port>"
   export REGISTRY_USERNAME=<username>
   export REGISTRY_PASSWORD=<password>
   export REGISTRY_CA=<path to the cacert file on the bastion>

4. Execute the following command to load the air-gapped image bundle into your private registry using any of the relevant flags to apply variables above:

   CODE

   dkp push bundle --bundle ./container-images/konvoy-image-bundle-v2.8.1.tar --to-registry=${REGISTRY_URL} --to-registry-username=${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.

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-v2.8.2.tar --to-registry=${REGISTRY_URL} --to-registry-username=${REGISTRY_USERNAME} --to-registry-password=${REGISTRY_PASSWORD}

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-v2.8.2.tar --to-registry=${REGISTRY_URL} --to-registry-username=${REGISTRY_USERNAME} --to-registry-password=${REGISTRY_PASSWORD}
