I followed the README instructions and ran webcenter/activemq in Kubernetes with the following variables: ``` ACTIVEMQ_ADMIN_PASSWORD=foo ACTIVEMQ_ACTIVEMQ_USERS_user1=bar ``` However all attempts to access ActiveMQ with these credentials fail with 401 Not Authorized (REST API). I have shelled into the container and verified the variables are set. How is this supposed to work? Do you have a script which should update `conf/jetty-realm.properties`? If so, it's not working.
