Zora Helm Chart¶
A multi-plugin solution that reports misconfigurations and vulnerabilities by scanning your cluster at scheduled times.
Installing the Chart¶
To install the chart with the release name zora in zora-system namespace:
helm repo add undistro https://charts.undistro.io --force-update
helm repo update undistro
helm upgrade --install zora undistro/zora \
-n zora-system \
--version 0.8.4 \
--create-namespace \
--wait \
--set clusterName="$(kubectl config current-context)"
These commands deploy Zora on the Kubernetes cluster with the default configuration.
The Parameters section lists the available parameters that can be configured during installation.
Tips:
List all charts available in
undistrorepo usinghelm search repo undistroUpdate
undistrochart repository usinghelm repo update undistroList all versions available of
undistro/zorachart usinghelm search repo undistro/zora --versionsList all releases in a specific namespace using
helm list -n zora-systemGet the notes provided by
zorarelease usinghelm get notes zora -n zora-system
Uninstalling the Chart¶
To uninstall/delete the zora release:
helm uninstall zora -n zora-system
The command removes all the Kubernetes components associated with the chart and deletes the release.
