Install Docker Prerequisites (Ubuntu 22.04/24.04)

These steps install Docker Engine, the Compose plugin, and supporting packages for PyPNM’s container workflow. For broader Linux/macOS installation guidance, see the official Docker Engine docs.

Install flow (script-only, recommended)

Use the helper script on Ubuntu 22.04/24.04 without cloning the repo:

curl -fsSL https://raw.githubusercontent.com/PyPNMApps/PyPNM/main/tools/docker/install-docker-ubuntu.sh \\
  -o /tmp/install-docker-ubuntu.sh
bash /tmp/install-docker-ubuntu.sh

Repo clone path (if you cloned the repo):

tools/docker/install-docker-ubuntu.sh

Optional (non-production): allow your user to run docker without sudo.

sudo groupadd docker || true
sudo usermod -aG docker "$USER"
echo "Log out and back in for group changes to apply."

Uninstall (optional):

bash /tmp/install-docker-ubuntu.sh --uninstall

Once Docker is available, return to the PyPNM Docker install guide or run the helper script from the README.
