Kubernetes simple demo failing with OpenShift 3.7.2 and latest FMP
by Galder Zamarreno
Hey Sebastian,
I'm trying to update simple tutorials to Infinispan 9.2.2.Final but
Kubernetes demo does not seem to be working.
I've started OpenShift 3.7.2 and have updated FMP to 3.5.33 and build
fails. Error is:
> error: build error: image "java:8-jre-alpine" must specify a user that is
numeric and within the range of allowed users
Cheers,

by Sebastian Laskawiec
Ok, so how about doing the same thing you suggested, but just more
explicitly - adding node-identifier="${jboss.node.name*:1*}". This way the
bare metal deployment should be happy (since the default is still 1) and we
wouldn't need to override it in Infinispan.

Hi Sebastian,
Did you mention something about x-site not working on master?
The reason I ask is cos I was trying to create a state transfer test for
[1] and there are some odds happening.
In my test, I start LON site configured with NYC but NYC is not up yet.

Infinispan chat moves to Zulip
by Tristan Tarrant
For over 9 years Infinispan has used IRC for real-time interaction
between the development team, contributors and users. While IRC has
served us well over the years, we decided that the time has come to
start using something better. After trying out a few "candidates" we
have settled on Zulip.
Zulip gives us many improvements over IRC and over many of the other
alternatives out there. In particular:
* multiple conversation streams
* further filtered with the use of topics
* organization management to organize users into groups
* it's open source
So, if you want to chat with us, join us on the Infinispan Zulip
Organization [1]

Re: [infinispan-dev] [wildfly-dev] WFLYTX0013 in the Infinispan Openshift Template
by Sebastian Laskawiec
Fair enough Tom. Thanks for explanation.
One more request - would you guys be OK with me adding a node-identifier="${
jboss.node.name}" to the transaction subsystem template [1]? This way we
wouldn't need to copy it into Infinispan (since we need to set it).
