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.
dkp-air-gapped-bundle_v2.6.0_linux_amd64.tar.gz, and extract the tarball to a local directory:CODE
tar -xzvf dkp-air-gapped-bundle_v2.6.0_linux_amd64.tar.gz && cd dkp-v2.6.0
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>
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-v2.6.0.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.
To increase Docker Hub's rate limit use your Docker Hub credentials when creating the cluster, by setting the following flag
--registry-mirror-url=https://registry-1.docker.io --registry-mirror-username= --registry-mirror-password= on the
dkp create cluster command.
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-v2.6.0.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-v2.6.0.tar --to-registry $REGISTRY_ADDRESS
