Add glibc version 2.28+ limitation for using opm

[bysnupy]

• Version: v4.6+

• Description:
  If the linux has not glibc more than v2.28, you can face error /lib/x86_64-linux-gnu/libc.so.6: version 'GLIBC_2.28' not found (required by ./opm), when you run the opm.

• Reference: https://bugzilla.redhat.com/show_bug.cgi?id=1892004#c3

At this time our proposed solution is to update the official openshift 4.6 docs to describe these limitations for the opm build on linux.

@jianzhangbjz, will you PTAL and confirm that this change is valid for versions 4.6+?

This doc looks great but I'm a little concerned it's written explicitly for linux users.

opm does not have a hard requirement on podman, users can use docker as a container tool instead. podman is also linux only.

For mac/windows the glibc requirement is not required, since the binary is statically linked on those platforms.

My suggestion would be to put Prerequisites (linux) or something like that to express that these prerequisites are for linux users only. Also there are bugs in podman 1.x that currently affect opm, maybe we could recommend using podman 2.x as well.

@exdx, which specific version of podman is better to list as the minimum?

We (OLM) haven't documented a specific version to recommend for users, so I couldn't say for sure. But here is an example of a recent bug in opm that was due to an underlying podman issue that was fixed in v2.0.0+

https://bugzilla.redhat.com/show_bug.cgi?id=1894167

That being said older versions of podman will work fine for general use cases but can run into edge cases like the one above.

So I think something like podman version 1.4.4+ (version 2.0+ recommended) is fair

@kalexand-rh What about changing it as follows ? Or if you have any suggestion, let me know that please. I can modify our best result. I remember the podman version is written on the multiple sections in the docs. It has potential issue due to the bug. So I think we had better change all places related with those places either.

Prerequisites for Linux
* `podman` version 1.4.4+ (version 2.0+ recommended)
* `glibc` version 2.28+

I've changed as I previously mentioned. I think we need another PR to change additional the podman recommend version in the related other places. It's different topic with this PR.

@kalexand-rh Could you PTAL ?

[kalexand-rh]

@jianzhangbjz, will you PTAL?

[kalexand-rh]

I think this change looks good, and I'll merge it as soon as @jianzhangbjz approves it.

[jianzhangbjz]

Sorry for the late reply! Looks good to me, thanks all!

@kalexand-rh Would you PTAL if you have time ? Thank you for your review.

I still get same error in WSL ( which is ubuntu 18.04). I am using opm downloaded from https://mirror.openshift.com/pub/openshift-v4/x86_64/clients/ocp/latest-4.9/?extIdCarryOver=true&sc_cid=7013a00000316d9AAA .

Is it it the right binary?
