Installing packages on top of UBI Minimal image in AWS ROSA environment

[hrishikeshvattoli]

Hi,

I have deployed a container from the image provided by Stackable's Airflow image based on UBI minimal in our ROSA cluster. I can list the repos inside the container., but it can't find the packages I am looking for. As I understand it, RHEL only makes a subset of packages available through minimal UBI images. So my question is, how can I install additional packages we want to install that are available in full version of repos. We have redhat subscription and I can install the same package from the CRB repo in our EC2 machines.

Hi,

that is a good question that has not come up before.

According to the RedHat docs it is possible to pass through entitlements from the host system to a container. But I'm not sure if this also applies to OpenShift/ROSA.

You said you tried and it failed. In that case I'd suggest one of us opens a support case with Red Hat to ask about best practices here. Shall we or do you want to?

Out of curiosity: Can you tell me what you're trying to install?

I tried installing the package libsmbclient-devel which is a dependency for pysmbc package. In our EC2 based deployments, this package is coming from CRB repos. This repo is present in the stackable UBI image but the package is not available.

sh-4.4$ yum provides libsmbclient-devel
Repository packages-microsoft-com-prod is listed more than once in the configuration

Could you check with RedHat as well? I'll try from my end as well.
