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

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

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.

There's no Python 3.6 UBI 8 image... at least looking at the charts in the blog post. Why would they do a UBI 7 with Python 3.6 but not UBI 8?

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 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:

        $ docker pull registry.access.redhat.com/ubi8/python-36
Now I need to read up on S2I and podman.

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.

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.

Download Firefox Focus from the AppStore and enable it as an ad blocker for Safari. Works perfectly for me

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.

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 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.

Red Hat is commited to "maintain" the UB images, that means, basically, they will only provide critical updates to the ubi-8-appstream repo. For paying customers, this is the bridge to move workloads from centos to rhel and vice versa.

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.

Yes that's kind of strange. That's why I've created one for OpenJDK 8 and 11 yesterday https://hub.docker.com/r/ubi8/openjdk

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.

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".

IBM have their own JVM implementation - they could ship that. Or ship their own build of the OpenJDK like many people do.

Red Hat already distributes Java in the form of openjdk. Surely the packaging format is irrelevant?
