I am trying to use the docker create simple postgres server. I use the official postgres image as the basis of my container. My Dockerfile consists of the following commands:

The FROM postgres
The USER postgres
The RUN/etc/init. D/postgresql start & amp; & \
PSQL command to "CREATE USER USER WITH SUPERUSER PASSWORD 'USER'." & & \
Createdb -o user app

When I try to run it, I have an error:


PSQL: could not connect to server: No to the file or directory
Is the server running locally and has
Connections on the Unix domain socket "/var/run/postgresql/. Supachai panitchpakdi GSQL. 5432"?

What did I do wrong?
