  At the beginning we tried to avoid making any custom changes to the images in question (XWiki and Bitnami's MySQL). But XWiki running as root, didn't fly. So we had to create a custom image with minor changes to enable it to run as a unprivileged uid/gid: 30001.

  We're going to deploy XWiki as a [[statefulset>>https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/]] using [[Helm>>https://helm.sh/]], the Database (MySQL) and the App, each will have a volume to store their information. As I mentioned, in our case, we need to perform several additional steps.

  This will create 2 PVs that we'll use later. Notice //nodeAffinity//, linking the deployment to a specific node (the pods can run only at that location, as the PV is defined only there).
--Download the Charts and Values file:
++Now we can install XWiki's charts (repo) and download it's //values.yaml// file:
++{{code language="sh" layout="LINENUMBERS" title="# Charts and Values"}}
++helm repo add xwiki-helm https://xwiki-contrib.github.io/xwiki-helm
++helm repo update xwiki-helm
--
++curl -LO https://raw.githubusercontent.com/xwiki-contrib/xwiki-helm/master/charts/xwiki/values.yaml
++{{/code}}
++
++Modify the values.yaml file, our example has:
++
++* Using custom image (so it won't run as //root//).
++* Increased memory/core usage allowance.
++* Running as UID/GID 30001.
++* Dropping all capabilities.
++* Using MySQL.
++* Enabling persistence.
++* Ingress (Nginx).
++* TLS (Cert manager)
++
++You can download our example from the attachment area.
++
++Once you have your custom [[//values.yaml//>>attach:values.yaml]] file, deploy the app with Helm:
++
++{{code language="sh" layout="LINENUMBERS" title="# Helm install"}}
++helm install --namespace behemoth-wiki --create-namespace \
++  --values values.yaml \
++  behemoth-xwiki xwiki-helm/xwiki
++{{/code}}
++
++=== Upgrade ===
++
++To upgrade XWiki, you should read the content in [[XWiki official Helm pages regarding upgrades>>https://extensions.xwiki.org/xwiki/bin/view/Extension/XWikiHelm/#HUpgrading]].
++
++Theoretically, if there aren't any breaking changes or prerequisites, you can run:
++
++{{code language="sh" layout="LINENUMBERS" title="# Helm upgrade"}}
++helm upgrade --namespace behemoth-wiki \
++  --values values.yaml \
++  behemoth-xwiki xwiki-helm/xwiki
++
++{{/code}}
++
++=== Uninstall ===
++
++To fully remove XWiki, use the following commands:
++
++{{code language="sh" layout="LINENUMBERS" title="# Uninstalling"}}
++helm uninstall --namespace behemoth-wiki behemoth-xwiki
++kubectl -n behemoth-wiki delete pvc/data-behemoth-xwiki-mysql-0
++kubectl -n behemoth-wiki delete pvc/xwiki-data-behemoth-xwiki-0
++kubectl delete -f pv_storage.yaml
++kubectl delete namespace behemoth-wiki
++{{/code}}
++
++This will uninstall the chart, delete the PVCs, delete the PVs and lastly, delete the namespace.
