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.
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.
I actually see this as another reason to stay below the 'lawsuit radar.' A quick search doesn't seem to turn up anything that looks like a showstopper for the acquisition so presumably while it isn't "done" it is likely to complete, would you agree?
Ah, I understand that former Sun employees have a sword to fight with Oracle, but no one else, besides a timid IBM offer, was that interested into buying Sun assets.
Additionally IBM, Red-Hat and Oracle, collaborate on OpenJDK development and are the few set of companies that actually contribute new language features, with Oracle still having like 90% of contributions.
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.
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 table that indeed includes python-36. It doesn't seem to be usable out of the box, but I was able to pull it with Docker:
Edit: not sure what I did wrong the first time, but it does work fine in Docker:
$ docker run --rm -it registry.access.redhat.com/ubi8/python-36 python
Python 3.6.8 (default, Apr 3 2019, 17:26:03)
[GCC 8.2.1 20180905 (Red Hat 8.2.1-3)] on linux
Type "help", "copyright", "credits" or "license" for more information.

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.
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.
But isn't that the point? This is intended for RHEL users who previously had trouble shipping Docker images based on RHEL that Red Hat would provide support for. Not so much for non-RHEL users.
It will also be attractive for ISVs who want to partner with Red Hat.
Disclosure: I work for Pivotal, we compete with Red Hat in a number of areas.
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
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 leadership that free-as-in-libre software is a good thing. If people just complain when it's also not free-as-in-gratis, the community is shooting itself in the foot.
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...
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.
Thanks for the info, that's good to know. I was speaking form ignorance on that point, obviously (since I was wrong). The point still stands though, Red Hat needs to make money, so we shouldn't expect them to eliminate all their options for monetizing something (which I assume you agree with given your other comments :) )
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?
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.
