Hey Ashish, Thanks for the update. Adding our chart to incubator section of helm community charts repository sounds great. Although (unlike Dockerhub) this repo is for community charts and not really official charts of the respective installations, but supporting this chart in the community chart repo should help with the visibility. Lets also work on adding tests to the helm chart to ensure things are going fine. Best, Shubham.

Hi everyone,
Update on HELM project:-
We have added some features to the chart that includes:- * Making chart configurable with both mysql and postgres database * We are now using configmaps and secrets for storing database credentials * We use helm dependency to manage the dependencies of the chart
I think our chart is ready to be deployed in the incubator section of helm community repo. <https://github.com/helm/charts> If you guys agree I would make the necessary changes required to deploy it there.
Thanks - Ashish

Hi everyone,
The first week update of helm chart xwiki project. We currently have a chart that would deploy xwiki mysql stateful service with a persistent volume. The link to the repo:-
Thanks for the update.
Would be great if you could update the README file to explain who to use it.
Thanks -Vincent
Thank You Ashish

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?
Yes we can test using minikube one
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/DatabaseSuppo...
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 repository. Helm charts are hosted there. Organizations like mysql, wordpress uses it. https://github.com/helm/charts 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
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.
