Build

make podman.raw

Use

Copy podman.raw to /var/lib/extensions.

Copy configs from /usr/etc/ into the appropriate directories in /etc. Remove the .example extensions.

If you want an example containers.conf, you can retrieve it from here Or simply curl -O /etc/containers/containers.conf https://raw.githubusercontent.com/containers/common/main/pkg/config/containers.conf

Optional: If you want rootless containers to work, disable selinux in /etc/selinux/config - must be disabled not permissive. Default file is a symlink so make a copy (cp /etc/selinux/config{,-}; mv /etc/selinux/config{-,})

Optional: If you want remote podman services, run systemctl enable --now podman.socket

If you want to remove docker entirely, visit here
