Upgrade Vault¶

Pre-requisites¶

Vault >= 1.15 is deployed
In the case of upgrading vault-k8s, it is recommended to have at least 5 units deployed and active to ensure minimal to no downtime.

Create a backup of your Vault data following this guide (in case anything goes wrong during the upgrade).
Make sure to save your unseal key(s), as this operation will seal all units.
Run juju refresh vault --channel=$VAULT_HIGHER_VERSION, where VAULT_HIGHER_VERSION is any 1.x version higher than the one you currently have deployed.
