Configure Docker 19.03+ on your workstation

Anthos clusters on bare metal helps you install Docker on your bare metal machines in the following scenarios:

  • If your bare metal machines don't have Docker installed, bmctl installs 19.03.13 or later.
  • If your bare metal machines have Docker 19.03.5 or earlier installed, bmctl upgrades Docker to version 19.03.13 or later.

Follow these steps to manually install Docker:

  1. Remove any previous Docker version:

    sudo apt-get remove docker docker-engine containerd runc
  2. Update your package manager:

    sudo apt-get update
  3. Install Docker 19.03+:

    sudo apt-get install \
      apt-transport-https \
      ca-certificates \
      curl \
      gnupg-agent \
      software-properties-common \
  4. Verify you are now running version 19.03+:

    sudo docker version
  5. Compare your output with the following example to ensure the Client and Server versions are 19.03+ :

     Client: Docker Engine - Community
     Version:           19.03.13
     Server: Docker Engine - Community
      Version:          19.03.13
