Minimum Requirements
Confirm container runtime
After running scripts/install_prerequisites.sh, verify the runtime for your OS. The quickstart writes .stingar-runtime in your install directory.
Docker (Ubuntu / Debian)
docker ps
docker compose version
Expected: Docker lists containers (possibly empty); Compose V2 reports a version.
Podman (RHEL / Rocky / AlmaLinux)
podman ps
podman compose version
Expected: Podman responds without errors; podman compose version reports Compose V2.
If Docker shows permission denied on /var/run/docker.sock:
Ensure your user is in the docker group and log out/in, or on RHEL use the Podman install path instead.
Python
python3 --version
STINGAR quickstart requires Python 3 for configure_stingar.py.
If all checks pass, proceed to Run Installation Script.
See Container Runtime for the full Docker vs Podman matrix.
