Hi, I'm tried this,

kmw@caltek$ sudo docker run -it postgres:10-alpine /bin/bash
bash-5.0# whoami
root
bash-5.0# su - postgres
b030bcb67163:~$ psql -c "show data_directory"
psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
b030bcb67163:~$

but nothing happen here

Dear Binaca,

since nobody else answered so far: i have never used the docker image, so i have to do some guessing here. To me, this looks as if in the docker image, the postgres server was not started and/or it was not initialized (via initdb) yet.

i would expect that the docker script would do so for you, but maybe something went wrong on this...
