node-red command not found

[micma42]

Hi,
I am trying to add password protection to the Node-Red-Backend as described in c't FAQ Node-Red. According to the Node-Red Doku, node-red-admin does not have to be installed separately, but is included in the node-red command since version 1.1.0. My recently cloned ct-Smart-Home has version 1.2.9.

I cannot get these commands to run, though. This is what I did:
pi@raspberrypi:~ $ docker exec -it ct-smart-home_nodered_1 /bin/bash
bash-5.0# node-red admin hash-pw
bash: node-red: command not found

I also tried to install node-red-admin with npm in the docker bash. This did execute with lots of warnings and errors, but then also yielded a
bash-5.0# node-red-admin hash-pw
bash: node-red-admin: command not found

Hints on what I missed are highly appreciated.
