Upgrade Notices

Big Bang does not support Vault and SSO out of the box. If you have enabled SSO by following some of the options documented in https://repo1.dso.mil/big-bang/product/packages/vault/-/blob/main/docs/keycloak.md , you may need to add a route for bb-common to allow the sso.

This can be done with:

addons:
  vault:
    values:
      networkPolicies:
        egress:
          from:
            vault:
              to:
                definition:
                  sso: true
