Create an AMI

Create an AMI using the DKP image builder

Create an AMI to be used in an air-gapped cluster

Using the Konvoy Image Builder, you can build an AMI without requiring access to the internet by providing an additional --override flag.

  1. Create the directories where you will place the air-gapped bundles:

    mkdir artifacts
    mkdir artifacts/images
  2. Define an environment variable for the Kubernetes version that corresponds with Konvoy release you are installing. You can find the correct Kubernetes version by checking the release notes for the release you are installing.

    export VERSION=1.22.8
  3. Set an environment variable for the AMI’s OS you are will be using. The OS packages bundles will contain the RPMs for Containerd, Kubernetes and all of their dependencies required to install these packages without access to any external RPM repositories. The available options are:

    • centos_7_x86_64
    • centos_7_x86_64_fips
    • redhat_7_x86_64
    • redhat_7_x86_64_fips
    • redhat_8_x86_64
    • redhat_8_x86_64_fips
    export BUNDLE_OS=centos_7_x86_64
  4. Download the OS packages bundle:

    curl --output artifacts/"$VERSION"_"$BUNDLE_OS".tar.gz --location"$VERSION"_"$BUNDLE_OS".tar.gz
  5. Download the Kubernetes images bundle. This bundle includes the necessary images for kubeadm to bootstrap a Kubernetes Node.

    The available options for each Kubernetes version are:

    • <version>_images.tar.gz
    • <version>_images_fips.tar.gz
    curl --output artifacts/images/"$VERSION"_images.tar.gz --location"$VERSION"_images.tar.gz
  6. Download the PIP packages. This bundle includes a few packages required by DKP to bootstrap machines.

    curl --output artifacts/pip-packages.tar.gz --location

    NOTE: If you’re installing V2.2.0 or V2.2.1, skip to step 9, as those releases did not have separate containerd packages.

  7. Set a variable that indicates which os-specific containerd bundle to download:

    export CONTAINERD_OS=centos-7.9-x86_64

    Note: available packages are:

    • centos-7.9-x86_64
    • rhel-7.9-x86_64
    • rhel-8.2-x86_64
    • ubuntu-20.04-x86_64
    • ubuntu-18.04-x86_64
  8. Download the containerd bundle.

    curl --output artifacts/containerd-1.4.13-d2iq.1-"$CONTAINERD_OS".tar.gz --location"$CONTAINERD_OS".tar.gz
  9. Follow the instructions to build an AMI in the setting an additional --overrides overrides/offline.yaml flag.

Then, you can seed your docker registry.
