I am trying to install a rpm from a url using the 8-slim image. Microdnf apparently doesn't support this. I am able to install yum, but then all yum commands fail.

I would recommend using the oraclelinux:8 image if you want to install a third-party RPM (as it includes the full DNF client). However, this should work, so let's debug. Do you perhaps need to set a proxy to access yum.oracle.com from this machine? If so, you should pass a build-time environment variable to set https_proxy to the right value.

I don't think that's it because I can run the 8 image without the https_proxy.

Can you check the content of /etc/yum/vars/ociregion on the 8-slim image (after installing the full yum client)? It should either be empty (if you're not on OCI) or contain a valid OCI region, e.g. -phx or -syd.

The file doesn't even exist.

touching this file makes it work! Is this a bug or a necessary step?

from container-images.

It's half a bug. :) Let me review this with engineering and get back to you. Glad we have a workaround for now though.

Also out of curiosity is there a way to get this to work with dnf? Based on the docs I've read, dnf relies on either a [repository] section in /etc/dnf/dnf.conf or uses /etc/yum.repos.d. The latter isn't present if I don't install yum, and I can't figure out what I need to do to add ol8_baseos_latest as a repo to dnf.

from container-images.

Sure, you can add something like this to /etc/dnf/dnf.conf:

[ol8_baseos_latest]
name=BaseOS
baseurl=http://yum.oracle.com/repo/OracleLinux/OL8/baseos/latest/x86_64

[ol8_appstream_latest]
name=AppStream
baseurl=http://yum.oracle.com/repo/OracleLinux/OL8/appstream/x86_64

Essentially, it's identical to the layout of the /etc/yum.repos.d/oracle-linux-ol8.repo file, though you'd still need to move that one out of the way.
