Description Christian Kellner 2020-09-10 16:00:55 UTC

In the osbuild-composer and koji-osbuild CI, we use a set of containers (a database one, a kerberos kdc one, one that is running koji hub and one for the builder). The use a custom network "org.osbuild.koji" and the containers want to talk to each other over network, addressing each other via their hostnames. This works fine on Fedora, but does not on RHEL, because the dnsname plugin is not shipped.

Assigning to Jindrich to start.  We might need Lokesh or Matt to stir the pot on this one too.  Discussed during scrum meeting today.

Comment 9 Joy Pu 2020-11-11 15:20:37 UTC

Thanks Jindrich for the information. Test with podman-plugins-2.1.1-3.module+el8.3.1+8686+2a59bca3.x86_64 and podman-2.1.1-3.module+el8.3.1+8686+2a59bca3.x86_64. It works as expect. Update the configure file and start two containers, try to ping one container from another. It works as expect. So set this to verified. Details:
# podman  ps
