Helm chart for dCache deployments in Kubernetes

TL;DR

helm repo add dcache https://gitlab.desy.de/api/v4/projects/7648/packages/helm/test
helm repo update
helm install my-release dcache/dcache

Run special version

helm  install --set image.tag=10.0.3  my-release dcache/dcache

Run only pools

Start pools d and f

helm  install --set image.tag=10.0.3 \
    --set dcache.door.enabled=false  \
    --set "dcache.pools={d,f}"  my-release dcache/dcache

Add extra onfiguraton to dcache.conf of layout.conf files

The configuration properties dcache.configExtraPre, dcache.configExtra, dcache.layoutExtraPre and dcache.layoutExtra allow adding an extra configurations at the begging and at the end of the generated dcache.conf and layout.conf files.

dcache:
  configExtra: |
    custom.property = value

  layoutExtra: |
    [customDomain]
    [customDomain/cell]

helm  install --values custom-config.yaml my-release dcache/dcache

Zookeeper

dCache requires a Zookeeper instance to operate. You can either use an external Zookeeper or deploy an embedded Zookeeper instance together with dCache. By default, the chart is configured to use an external Zookeeper instance running at cells-zookeeper:2181. To deploy an embedded Zookeeper instance, set the following value:

zookeeper:
  embedded: true

or use the command line:

helm  install --set zookeeper.embedded=true my-release dcache/dcache

The list of Zookeeper servers can be configured via the zookeeper.servers value.

zookeeper:
  servers: zookeeper1:2181,zookeeper2:2181,zookeeper3:2181

or via command line:

helm  install --set zookeeper.servers="zookeeper1:2181,zookeeper2:2181,zookeeper3:2181" my-release dcache/dcache

Enable CTA plugin

helm  install --set dcache.plugins.cta.enabled=true  my-release dcache/dcache
