Container Engine

We recommend using Podman as your container engine. Podman is rootless by design, which makes it a more secure solution. Its daemonless design removes the single point of failure created by Docker’s central daemon.

Installation (Podman Desktop)

brew install podman

Setup Podman container engine

On macOS and Windows, running the Podman container engine requires running a Linux virtual machine.

By default, Podman Desktop initializes a Podman machine with a standard configuration.

Consider creating a custom Podman machine to:

  • Control the assigned resources: CPUs, memory, and disk size.
  • Use a custom boot image.
  • Use the rootful connection by default, for example to run Kind.
  • (On Windows) Route the traffic through the network connection from your Windows session.

Prerequisites​

  • The Podman executable is installed.

Procedure​

  • Go to Settings > Resources.
  • In the Podman tile, click Create new.
  • In the Create a Podman machine screen:
  • Name: Enter a name, such as podman-machine-default.
  • CPU(s): Select the number of CPUs, e.g. 2.
  • Memory: Select the memory size, e.g. 2048 MiB
  • Disk size: Select the disk size, e.g. 20 GiB.
  • Image path (Optional): Select a bootable image containing a virtual machine with Podman.
  • Machine with root privileges: Enable to use the rootful connection by default. Required to use Kind on Windows.
  • (On Windows) User mode networking (traffic relayed by a user process): - Enable to route the traffic through the network connection from your - Windows session. Required to access resources behind your VPN connection.
  • Click Create

Docker compose

Docker compose has more features than Podman compose and therefor the recommended tool for running compose files.

Install docker compose by executing the following:

brew install docker-compose

Podman compose will now using /opt/homebrew/bin/docker-compose instead.

Linking Docker

Some test frameworks call the docker command. Becaus To resolve this we have to make a static link to the podman command. Find the path to your podman binary:

which podman

and then replace the below with your path and run the command:

sudo ln -s <path-to-your-podman-binary> /usr/local/bin/docker
