Setup Podman on macOS
Podman is a utility that can be used to create and maintain containers. This post will teach you how to set up Podman on macOS and perform some basic commands.
Preparation
Homebrew
Install Homebrew:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
bash 5
Install via Homebrew:
brew install bash
Podman
Install via Homebrew:
brew install podman
Podman Machine
Create and start your first Podman machine (2 CPUs, 100GB disk, 4GB memory). Podman machines are backed by QEMU. This will become the default Podman machine:
podman machine init --cpus 2 --disk-size 100 --memory 4096
List all machines:
podman machine ls
NAME VM TYPE CREATED LAST UP CPUS MEMORY DISK SIZE
podman-machine-default* qemu About a minute ago About a minute ago 2 4.295GB 107.4GB
Start the default machine:
podman machine start
Verify the installation:
podman info
The machine will be configured in rootless mode. If your containers require root permissions (e.g. ports < 1024), or if you run into compatibility issues with non-podman clients, you can switch using the following command:
podman machine set --rootful
Test
Run the Hello World container:
podman run hello-world
Podman Desktop
To start a podman machine automatically at login, also install the Podman Desktop:
brew install --cask podman-desktop
