Podman - Publish UDP Port to host

If not explicit stated, Podman will publish a TCP port by default. To publish an UDP port, simply add the suffix /udp to the container port part like this:

Syntax:

--publish, -p=[[ip:][hostPort]:]containerPort[/protocol]

Example:

-p 5053:5053/udp

For compose files:

ports:
  - "5053:5053/udp"

Quick check:

$ ss -tupln | grep 5053
udp   UNCONN 0      0                  *:5053             *:*   user[...]

It is enough to add the suffix to the container port.
