The tag of vault-k8s image is different with the chart version at 0.7.0 which confused me

I’m running hashicorp/vault 0.4.0 in my cluster, and i want to upgrade to the latest version.

I’ve set the image tag as a variables in my values.yaml file at the beggining, so when i trying to upgrade vault with the values.yaml it got failed as there’s’ no k8s-vault with tag 0.7.0. hashicorp/vault-k8s. so i have some questions here:

  1. The tag of image is different with chart version, does it as expected?
  2. whtat’s the differnet with vault and k8s-vault?
  3. Is there some best-practices for the use case of integrate vault-k8s with terraform?
