charts are hosted there. Organizations like mysql,
wordpress uses it.

But in addition to that, we can build our own charts repository locally,
and host it. Similar to docker run command, we have helm update command
Hi Ashish,
Yes we can test using minikube one

I will be presenting my project "Helm Chart for XWiki" to all of you.
Following
are the relevant details.
Helm Chart for XWiki
Mentors: Shubham Jain, Neha Gupta
Technologies: Kubernetes, Docker, other if required
Overview
The proposed project is a helm chart that would deploy xwiki as highly
available and reliable. It should be configurable with different
databases(either a standalone database or a clustered one) that are
configurable with xwiki. It would give the option to either configure
solr
externally (standalone or clustered) or managed
within the container.
It also needs to be deployed on various Servlet Containers and with a
LibreOffice server configured.
In short, it should support all the configurations supported by the
official XWiki Docker images :)
It
should deploy the app on a shared file system like a rook. It should
support Istio virtual services, istio matrix, and istio distributed
tracing
and should be a secured system with RBAC and
security credential
rotation.
Ok I have no knowledge about this… The shared file system sounds good to
support clustering XWiki for the permanent directory sharing.
The chart should be easily deployed on GKE and
amazon EKS.
On locally on minikube for testing I guess?
Features
-> Support for different Databases
-> Choice between using an external database, a single node DB or a
multi-cluster DB setup
-> Support for shared file system
-> Support for istio and it's services
-> RBAC, SSL and other security methods
If you have any features in mind that should be added please feel free to
reply to this mail.
Some Design Questions?
-> Which Databases should be supported?
See
https://dev.xwiki.org/xwiki/bin/view/Community/SupportStrategy/DatabaseSupp…
More generally see the XWiki Docker image documentation and
https://dev.xwiki.org/xwiki/bin/view/Community/SupportStrategy
-> As we have to detach solr out of the docker
container(run it in an
independent container) would be there a requirement for a code change,
and
we should approach it?
See the doc for Solr which explains how to configure an external SOLR.
There are some XWiki code/config to deploy in the external SOLR AFAIR.
comunity controls chart
-> Apart from solr is there any other stateful
service that could or
should
be detached from the docker container?
Which docker container are you referring to? The Servlet Container one?
xwiki:lts-mysql-tomcat Here is my
current repository which deploys XWiki for MySQL database
using
official XWiki docker container:-
https://github.com/ashish932/xwiki-helm-chart/
Will need to have a look. Some additional questions:
1) Is there an official place for publishing helm charts, similar to
dockerhub for docker images? How do you provide the helm charts to XWiki
users in term of packaging? In other words, what will we/you document on
https://www.xwiki.org/xwiki/bin/view/Documentation/AdminGuide/Installation/
?
Yes, There is a centralized community control chart management 2) How do you plan to have smoke tests for the XWiki
Helm charts, as part
of the build, to verify that they work fine? How can we execute XWik’s
functional tests based on TestContainers using Helm Charts?
There are some tools available
chart-testing(started by helm) -98 commits
terratest - 1039 commits (It looks a good tool to use)
3) Do the helm charts for XWiki need to be built? If
so, can it be done
with Maven? Since we’ll be offering several I guess, how do you avoid code
duplication and make maintenance of them as simple as possible?
No, the charts don’t need to be built externally, though it gets compressed
when pushed f we build to chart repository(this is an automatic step in
case of official chart repo and we can automate using ci our own chart repo)
4) Could you provide a roadmap with various milestones and dates? See the
last roadmap email I sent on the devs list and please
reply to it.
Okay I would work on that and update the progress on the mail thread
5) It seems you missed the bonding period so you’ll
need to catch up on
that. Could you pick some jira issue and work on them quickly? This is to
make sure you use the proper xwiki communication channels, learn to work
with the xwiki team and start understanding the xwiki architecture, and how
extensions are developed for XWiki. Since you’re a bit late, you’ll need to
catch up and achieve this very quickly now and be present full time on the
xwiki chat :)
I would start doing that
6) Idea: please review the issues on the XWiki Docker project’s jira.
Maybe you can help with those too as part of onboarding/bonding. It should
also give you additional use cases for the XWiki Helm Charts IMO.
Thanks! I’m eager to follow your work and see xwiki helm charts in action.
