@ebocchi thanks for starting this! I can deploy and test this but we need the image to be built first.
If merged I guess this will currently overwrite the image used in production gitlab-registry.cern.ch/sciencebox/docker-images/frontier-squid:4.17-2.1.

Do you think it would make sense to merge with BASE_TAG updated to 'gitlab-registry.cern.ch/sciencebox/docker-images/frontier-squid-el9' to make a separate EL9 image for testing purposes?

As a separate/independent next step I started sciencebox/charts#124 to prepare the chart for a squid update to v5.

Thanks @ebocchi , I tried it on a dev cluster, and ran cvmfs_config chksetup and ALRB db-fnget tests on the squids.
I did not see any problems. I think it should be okay to use in production.

Do you think it makes sense to merge with the same 4.17-2.1 tag so that it will start to be used transparently? I'm okay with whatever would be easiest.

[rptaylor]

@ebocchi any further thoughts on this? I think it's okay to merge, however you want to handle the tag version is fine with me.

I built and pushed a new image to gitlab-registry.cern.ch/sciencebox/docker-images/frontier-squid:4.17-2.1.el9

[rptaylor]

I deployed this image using chart frontier-squid-0.1.7 on our dev cluster, and run the ALRB db-fnget test and cvmfs_config chksetup on a node, all looked fine.

Squid pod logs and squidclient mgr:info also look fine.
