To upgrade Vault using the Bank-Vaults operator, complete the following steps.
- Check the release notes of Vault for any special upgrade instructions. Usually there are no instructions, but it’s better to be safe than sorry.
- Adjust the spec.image in field in the Vault custom resource.
- The Bank-Vaults operator updates the statefulset. (It does not take the HA leader into account in HA scenarios, but this has never caused any issues so far.)
