[Hawkular-dev] https://hub.docker.com/r/hawkular/*

[Jiri Kremser]

Hi,
  the Dockerhub is the image registry that is enabled by default for
dockerd. IMO, we can't support only our internal RH registries and ignore
the dockerhub. This is what we deliver to the community. Less and less
people are downloading zip files and installing stuff these days (or even
using package managers). If I want to try tool/product/project X (where X
can be prometheus, ) First thing that comes to my mind is to google for the
docker image and some short code (like `docker run -e foo=bar org/image`)
that I can copy&paste to the terminal and have everything set up correctly.
We have nothing like that today and that was 1 of the reasons, why I
started the hawkinit cli/tui tool.

Currently we have dozens of images there that are obsolete or that were
used for 1 particular use-case/demo. For instance the hawkular-metrics
https://hub.docker.com/r/hawkular/hawkular-metrics/tags/ has the latest
change before 2 years and contains bunch of images that have snapshot in
the tag. If I am a newcomer trying to play with hawkular-metrics, I would
run away quickly.

The very first image is the https://hub.docker.com/r/hawkular/hawkular/
which should be the "Hawkular", right? Last change is 1 year old and again,
for the newcomers it's hard to explain the fact that it's the old version
containing the old components, but it has the rich UI, while the new ones
have no UI, but new components.

Could you guys look and reply to this email if you want to preserve certain
image?
Currently these are 'maintained' and quite ok (I didn't go through all of
them):
* hawkular-services
* hawkular-openshift-agent
* wildfly-hawkular-javaagent
* wildfly-hawkular-agent-domain
* wildfly-hawkular-agent
* hawkular-website
* hawkular-grafana-datasource
* hawkular-openshift-agent-example-jolokia-wildfly (despite the name, (name
!= description))
... the rest seems to be abbandoned or was created for some demo and it's a
question if those images should be under the hawkular org, or if we
shouldn't move them to something like hawkular-labs or hawkular-examples,
or similar. I don't know.

One note to the naming: we have quite a lot of different agents without any
description or metadata in the image itself, what should I use and when? I
know that, mazz knows that and probably couple of other guys know that, but
people out there would have no idea.

Perhaps it would be good to have also some thoughts from people that are
relatively new in the team or work a lot with the d. images. Like Caina,
Paul, Josejulio.

wdyt, guys?
