Install Dependencies

By default, the Docker container engine will be used as the Kas container engine, but Podman can also be used.

DockerPodman

To install the Docker container engine on the Linux Host PC:

1. Add Docker's GPG Key.

   sudo apt-get update
   sudo apt-get install ca-certificates curl
   sudo install -m 0755 -d /etc/apt/keyrings
   sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
   sudo chmod a+r /etc/apt/keyrings/docker.asc
   

2. Add official Docker repository to the APT sources.

   echo \
   "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
   $(. /etc/os-release && echo "${UBUNTU_CODENAME:-$VERSION_CODENAME}") stable" | \
   sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
   sudo apt-get update
   

3. Install Docker container engine packages.

   sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
   

4. Add user to the Docker container engines user group.

   sudo groupadd docker
   sudo usermod -aG docker $USER
   

5. Log out and log back in for the changes to take effect.

To install Podman on the Linux Host PC:

1. Install Podman.

   sudo apt update
   sudo apt-get install podman
   

2. Set Podman as the Kas container engine.

   export KAS_CONTAINER_ENGINE=podman
