pgadmin connection error about postgres

[renzok]

Another variant to the recommended version of @yosifkit

sudo docker run --name pt -t -p 0.0.0.0:5555:5432 -d postgres

to expose the container internal port 5432 to port 5555 on your host machine.

Could you attach the logs from your pgadmin and postgres containers? docker logs [id | name]

WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run initdb.

Success. You can now start the database server using:

postgres -D /var/lib/postgresql/data

or
pg_ctl -D /var/lib/postgresql/data -l logfile start

It looks like your pgadmin is trying to connect to localhost, if that is being run in a container you will need to tell it to connect to the IP address of the postgres container. Here is how I connect with psql in a separate container:

docker run -it --rm --link some-postgres:postgres postgres psql -h postgres -U postgres
# can use the host "postgres" since container links will populate /etc/hosts

What are the docker run lines that you are doing?

renzok, your advice is helped. i did change port to 5555 and pgadmin start connect to database. thank you!
