Hi JB,

thanks for your detailed answer. I will try to create a static docker 
installation soon. I was searching for a documentation a half year ago. Looks 
like I should try it once more. The requirement is that I will have a lot of 
SNAPSHOT bundles to install I'm using docker currently for local development 
and rapid deployment (bundle:watch). Thanks for docker I can switch between 
different projects very fast. In production I have to rollout the development 
on a non-docker environment (yet ....) but release versions.

Looking around with features now I found some strange behaviour in karaf and 
want to check If I'm right ...

1) Can't remove repo

karaf@root()> feature:repo-list
Repository                        │ URL
──────────────────────────────────┼──────────────────────────────────────────────────────────────────────────────────────────────
[...]
cxf-3.3.1                         │ 
mvn:org.apache.cxf.karaf/apache-cxf/3.3.1/xml/features
[...]
karaf@root()> feature:repo-list
Repository                        │ URL
──────────────────────────────────┼──────────────────────────────────────────────────────────────────────────────────────────────
[...]
cxf-3.3.1                         │ 
mvn:org.apache.cxf.karaf/apache-cxf/3.3.1/xml/features
[...]

Is this a bug or a feature?



2) Found out that cxf 3.3.1 install both jetty 9.4.12.v20180830 and 
9.4.18.v20190429 bundles ... the bundles will not work together and the http 
system is not working (depends on the start order, I have a 50/50 change to 
bring http to work)

karaf@root()> feature:install cxf/3.3.1

3) for cxf 3.3.0 It's the same ...

Looks like I was lucky yesterday and had the correct start order. In 3.3.0 I 
found the same problem. And I found it will install 3.3.1 features also (maybe 
that's the problem)

karaf@root()> feature:install cxf/3.3.0

4) hmm - even after blacklisting cxf/3.3.1 two jetty versions will be installed 
also ...

I'm sure this was not happen before end fo April (v20190429)

I also found this to blacklist features

but ...


5) I blacklisted         
<repository>mvn:org.ops4j.pax.web/pax-web-features/7.2.10/xml/features</repository>

and now it's working *YES*

Ok, forget all the text before but from finding the problem (thuesday) to now 
(saturday) I was investigating a lot of time for ... hmm



6) Therefore .... How to avoid bad surprises (is that english?) in the future ?

I wan't to have a stable feature and repo list. Is it possible to disable 
'automatic update' of the repo-list and/or set a static list of repositories?

So it will not be possible a 'new' repository will bring me to wonder why the 
formerly working development is now in a critical state.

As I understand the problem this will also not be solved by a static karaf 
distribution. If I create a new distribution the same mechanism will provide 
'new' repos and the created karaf distribution is buggy too.



Thx & Regards
Mike
