It is bit surprising that they do not offer Java UBI image, considering that RH is one of the biggest Java vendors. Instead they are offering dotnet images of all things.

We are working on it. We provide the openjdk package in UBI now, you can build a container image from the base. I plan on publishing a blog entry soon, explaining how. Also, we are working on releasing a pre-built image.

I think it should be straightforward to install CentOS packages instead.

Sure, but then why stop there and not just go > FROM centos:8

Because "FROM centos:8" can't exist until after "FROM ubi8" exists. UBI will offer betas for RHEL 9, 10, 11, etc. It solves a chicken and egg problem for partners who need early access.

Presumably because Red Hat is a business and is trying to make money. You only get updates if you have a subscription. If you aren't a subscriber, these images probably aren't what you want. Get the CentOS equivalents instead. If CentOS doesn't meet your needs but RHEL would, I can only think that you should be a paying customer then.

You get updates with UBI, free of charge.

So the complaint is that this Red Hat product is best for Red Hat's paying customers, and that if you want to use Red Hat's products without being a paying customer, you not only have to use the community edition's packages, but you may as well start with the community edition's base image? Am I understanding that right?

You are fully correct, and it is only a complaint in regard to the submission originally titling UBE as an "Alpine alternative".

UBI lives in between community and product. It's a community thing if run without a subscription and a product if run on RHEL/OpenShift.

Because Red Hat 8 by default ships without an explicit default python version. See the discussion for the Red Hat 8 release a few days back. It was extensively debated and covered there: https://news.ycombinator.com/item?id=19848965

This doesn't have anything to do with the discussion of Python application streams. The linked blog post contains a table of UBI 7 images that includes python-27 and python-36, and a table of UBI 8 images that only includes python-27. I think the table is misleadingly presented as comprehensive ("the set of container images"). If you follow the "RHEL 8 How To" link at the bottom of the page, you'll find a larger tabl…

The exclusion of python36 from the UBI8 table is a mistake. I am working on getting it updated.

Unless you consider ancillary information like, IBM owns Redhat and hates Oracle, and Oracle has decided to extract money for anything Java + Enterprise, and UBI is targeted for Enterprise customers. When you consider that you realize that adding a Java UBI image would just set them up for a fight with Oracle and delay their ability to get moving with UBI.

IBM does not yet own RedHat, the deal will close in another couple of months. IBM cannot influence anything RedHat does yet.

What a sham. Very few packages are available in the yum repos from the UBI unless one is a RH customer. This will be a nonstarter unless anyone can install any package from the RHEL collection by default.

If there is a particular package you need in UBI, we would be happy to evaluate it. Please file a BZ under RHEL 7 or 8 under the ubi-* Product Component at http://bugzilla.redhat.com

Yeah, I think they'll struggle with adoption over the existing docker ecosystem and they should not be introducing such barriers just yet.

Red Hat doesn't necessarily care about adoption unless it leads to subscription revenue. It's easy enough to switch between CentOS and Red Hat. At some point I care enough about enterprise support and Red Hat's add-ons to make that switch and pay for it. And if I don't, Red Hat doesn't care. I really don't understand this pressure for companies to just literally give stuff away. It's hard enough convincing corporate…

TallGuyShort1, you are awesome :-) Thank you for the defense. We will evaluate adding packages to UBI as necessary, but you are right, we can't give all of RHEL away for free...

I tried to read this from my iPhone. I had to fight some sort of pop-up multiple times till I gave up. I did get to some page that were full of corporate speak. I got the sense that there is an interesting concept in there but can't be bothered fighting to find it.

Sorry about that. It's my corporate speak :-)

What are the differences between this and the previous rhel and rhel-minimal images? Distribution terms (and some subset of packages with different licensing) only? That's no small thing, but I want to make sure I'm not missing something.
