87 87  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.

145 145  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).

147 -Download the Charts and Values file:
147 +Now we can install XWiki's charts (repo) and download it's //values.yaml// file:
148 148  
149 +{{code language="sh" layout="LINENUMBERS" title="# Charts and Values"}}
150 +helm repo add xwiki-helm https://xwiki-contrib.github.io/xwiki-helm

153 +curl -LO https://raw.githubusercontent.com/xwiki-contrib/xwiki-helm/master/charts/xwiki/values.yaml
154 +{{/code}}
155 +
156 +Modify the values.yaml file, our example has:
157 +
158 +* Using custom image (so it won't run as //root//).
159 +* Increased memory/core usage allowance.
160 +* Running as UID/GID 30001.
161 +* Dropping all capabilities.
162 +* Using MySQL.
163 +* Enabling persistence.
164 +* Ingress (Nginx).
165 +* TLS (Cert manager)
166 +
167 +You can download our example from the attachment area.

169 +Once you have your custom //values.yaml// file, deploy the app with Helm:
170 +
171 +{{code language="sh" layout="LINENUMBERS" title="# Helm install"}}
172 +helm install --namespace behemoth-wiki --create-namespace \
