Following the instructions at https://docs.ploneintranet.org/installation/system-setup.html, I cannot run the docker container after building it under "appadmin" user with the command:
docker build -t gaia .
when I issue this command:
docker run -i -t \
-e LC_ALL=en_US.UTF-8 \
-e LANG=en_US.UTF-8 \
-v /home/appadmin:/app -w /app -u app gaia
and it hits this error:
docker: Error response from daemon: linux spec user: unable to find user app: no matching entries in passwd file.
There is no "app" user inside /etc/passwd file when I enter into the container in a simpler way:
docker run -it gaia
What could have gone wrong with the docker build or run? Does it require a specific docker version to build the container (mine is 18.06.1-ce)?
