Podman is the supported drop-in replacement for RHEL 8+.
To install Podman, run the following commands:
dnf install -y podman /usr/local/apnscp/bin/scripts/yum-post.php install -d podman siteinfo systemctl reload fsmount
In order for containers to keep running, you need to tell systemd to linger your user:
loginctl show-user <user> --property Linger loginctl enable-linger <user>
