Hi community,
I use Podman on CentOS 7.9 based distro. I use ClearOS 7.9 for my needs. Now I’m dabbling
with Podman and have the following question when I used Docker I could use the hostname to
call for another container instead of the IP address. How is this done with Podman? I must
admit I’m not very experienced with using Docker or Podman on the CLI. I know some basic
stuff but enjoy learning.
Regards,

Hi Marcel,
It might be end of day brain on my part, but I'm not sure which command
you're using with an ip? Could you reply with an example Docker command
that worked for you? In theory, you should be able to just replace
'docker' in your command with 'podman', and it will work.

Marcel,
Depending on your version, this should be the same as docker. I do not
recall offhand what version is in RHEL7. One thing that catches people is
that the default network does not have this feature enabled (just like
docker). To resolve containers by their name with DNS as sudo:
1. sudo podman network create foobar
2. sudo podman run ... --net foobar --name mycontainer ...
...
