Setup docker engine

-p 127.0.0.1:5432:5432 instead of -p 5432:5432. If you don’t explicitly tell it to run on localhost, it’ll run on0.0.0.0 which means other folks on the same network will be able to reach it. https://hub.docker.com/_/postgres => Gives a lot of info regarding docker secrets which should be the way forward.

docker pull postgres

OR for a specifig version

docker pull postgres:10

reference docker pull [OPTIONS] NAME[:TAG|@DIGEST]

mkdir -p $HOME/docker/volumes/postgres

NOTE -

1. use --rm flag if the docker of the same name already exists.
2. mount the /var/lib/docker to an external volume using the same -v flag. documentation

docker run --rm --name pg-docker -e POSTGRES_PASSWORD=[PASSWORD] -d -p 0.0.0.0:5432:5432 -v $HOME/docker/volumes/postgres:/var/lib/postgresql/data  postgres

If you are doing a fresh install using external volume then do the following:

example for external volumes

docker run --name pg-docker -e POSTGRES_PASSWORD=[PASSWORD] -d -p 0.0.0.0:5432:5432 -v /mnt/volume_nyc1_03/postgres:/var/lib/postgresql/data  postgres
