Regarding workspaces - workspaces aren't supported in the self hosted version. I think that's feature on http://app.clear.ml
so you should be able to pass additional stuff in this field directly during Helm apply
additionaConfigs is a section under apiserver
additionalConfigs: auth.conf: | auth { # Fixed users login credentials # No other user will be able to login fixed_users { enabled: true pass_hashed: false users: [ { username: "jane" password: "12345678" name: "Jane Doe" }, { username: "john" password: "12345678" name: "John Doe" }, ] } }
