Hi Paolo,

As far as I know, swarm clusters are unmaintained since 3 or 4 years. So it
won't work as expected.

Most of the magnum users are using kubernetes therefore its maintained.

For kubernetes clusters you can use fedora CoreOS 32. It works perfectly

You can use below link for installation.
