k8s/helm/secrets - secure secrets with encryption in helm git repo

Install plugin to helm

$ helm plugin install https://github.com/futuresimple/helm-secrets
##>> install package sops

Notes: I missed the fact that helm secrets expect the secret files to be names secrets.yaml (or secrets<xxx>.yaml)

Using keys in Azure Key vaults

Create key

AZ_AKV_RG="akv-infra"
AZ_AKV_LOCATION="Australia Southeast"
AZ_AKV_SUBSCRIPTION="Infrastructure"

az account set --subscription "$AZ_AKV_SUBSCRIPTION"
## Create multiple key vaults and keys each in a vault e.g.  keya in helm-comp-dev,  keyb in helm-comp-prd
ch="fdnb"
for en in prd; do
  AZ_AKV_NAME="helm-$ch-$en"
  echo "AZ_AKV_NAME=$AZ_AKV_NAME  ,  AZ_AKV_LOCATION=$AZ_AKV_LOCATION  ,  AZ_AKV_RG=$AZ_AKV_RG"
  if ! az keyvault create --name $AZ_AKV_NAME --location "$AZ_AKV_LOCATION" --resource-group $AZ_AKV_RG
    then
    echo "ERROR" ; exit 1
    fi
  #now check for kv in dns, it takes a couple of seconds, dont want to polute global dns beore it exists.
  i=0
  
  while [[ i -le 45 ]] ;
  do
    i=$((i+1))
    sleep 1 ; echo "i=$i dns for key vault does not exist yet sleep some more ..."
    done
  echo " Now create key --name $AZ_AKV_NAME in --vault-name $AZ_AKV_NAME "
  az keyvault key create --name $AZ_AKV_NAME --vault-name $AZ_AKV_NAME --protection software --ops encrypt decrypt
done
