+the docker containers in 10.11 branch don't contain any unix programs. That
+means there's no sh or bash, no cat etc etc. We need to have a shell to run
+our entrypoint and export the postgres URL as an env variable. To overcome
+this we insert a busybox binary as a config into the container. There's no
+action required on the side of the operator but it's important to note.
