Docker

• pushed by Docker Inc. (duh..)
• de-facto standard
• daemon running as root
• will never work on HPC machines
• neat for orchestration

Install

• Fedora: sudo dnf install docker
• Ubuntu: bit more complicated
• macOS: good luck!

podman

• pushed by RedHat
• allegedly a drop-in replacement for docker
• service running as user
• might work on HPC machines in the future
• used to be pre-installed on Fedora

Install

• Fedora: sudo dnf install podman
• Ubuntu: sudo apt install podman
• macOS: sudo brew install podman
