Controller Helm Chart

Azure Key Vault Controller reference


This chart will install a Kubernetes controller and a Custom Resource Definition (AzureKeyVaultSecret), that together enable secrets from Azure Key Vault to be stored as Kubernetes native Secret resources.

For more information see the main GitHub repository at https://github.com/SparebankenVest/azure-key-vault-to-kubernetes.

Note about installing both Azure Key Vault Controller AND Azure Key Vault Env Injector

If installing both the Controller and the Env Injector, they share the same Custom Resource Definition (CRD), so only one of them can install it. Set installCrd to false for either this Chart or the Env Injector Chart.

Installing the Chart

helm repo add spv-charts http://charts.spvapi.no
helm repo update
helm install spv-charts/azure-key-vault-controller \
  --namespace akv2k8s

Installation of both Controller and env-injector

helm install spv-charts/azure-key-vault-controller \
  --namespace akv2k8s
helm install spv-charts/azure-key-vault-env-injector \
  --set installCrd=false  --namespace akv2k8s

We set installCrd=false on the last helm chart we install, or else the second install (injector in this case) will fail when the CRD already exists.

Using custom authentication

helm install spv-charts/azure-key-vault-env-injector \
  --set keyVault.customAuth.enabled=true \
  --set env.AZURE_TENANT_ID=... \
  --set env.AZURE_CLIENT_ID=... \
  --set env.AZURE_CLIENT_SECRET=...
