offline

Offline installation is divided into the following four files, Download the corresponding files for your needs.

  1. kubeasy-v${KUBEASY_VERSION}.tar.gz
    • software packages and Pod images will be downloaded from the Internet
  2. kubeasy-binary-v${KUBEASY_VERSION}.tar.gz
    • software packages required to deploy kubernetes
  3. kubeasy-registry-v${KUBEASY_VERSION}.tar.gz
    • Pod images required to deploy kubernetes
  4. kubeasy-offline-v${KUBEASY_VERSION}.tar.gz
    • Using Docker to run kubeasy, kubernetes can be installed completely offline

If use the kubeasy-offline-v${KUBEASY_VERSION}.tar.gz, you need a deployment server. docker restarts and the deployment container is aborted because the installed docker and kubeasy methods are different.
