If you want to connect to an **external database server**, you can use either the IP address or the DNS as `POSTGRES_DB_HOST`. For instance, if the server is running on `mydns.net`, on port `5434`, the username is `postgres` and the password is `mysecretpassword`:
```console
$ docker run --name geonetwork -d -p 8080:8080 -e POSTGRES_DB_HOST=mydns.net -e POSTGRES_DB_PORT=5434 -e POSTGRES_DB_USERNAME=postgres -e POSTGRES_DB_PASSWORD=mysecretpassword geonetwork:postgres
$ docker run --name geonetwork -d -p 8080:8080 -e POSTGRES_DB_HOST=mydns.net -e POSTGRES_DB_PORT=5434 -e POSTGRES_DB_USERNAME=postgres -e POSTGRES_DB_PASSWORD=mysecretpassword -e POSTGRES_DB_NAME=mydbname geonetwork:postgres
```
If are want to **run postgres on a container**, you can use the container name as `POSTGRES_DB_HOST`: just make sure that containers can discover each other, by **running them in the same user-defined network**. For instance, you can create a bridge network:

And then you could launch geonetwork, making sure you join the same network, and setting the required environment variables, including the `POSTGRES_DB_HOST`:
```console
$ docker run --name geonetwork -d -p 8080:8080 --network=mynet -e POSTGRES_DB_HOST=some-postgres -e POSTGRES_DB_PORT=5432 -e POSTGRES_DB_USERNAME=postgres -e POSTGRES_DB_PASSWORD=mysecretpassword geonetwork:postgres
$ docker run --name geonetwork -d -p 8080:8080 --network=mynet -e POSTGRES_DB_HOST=some-postgres -e POSTGRES_DB_PORT=5432 -e POSTGRES_DB_USERNAME=postgres -e POSTGRES_DB_PASSWORD=mysecretpassword -e POSTGRES_DB_NAME=mydbname geonetwork:postgres
```
#### Configuration environment variables
These are some environments variables that can be set to configure the database connection:
- `POSTGRES_DB_HOST`: database host name.
- `POSTGRES_DB_PORT`: port where database server is listening (by default `5432`).
- `POSTGRES_DB_NAME`: name of the database. If it doesn't exist the container will try to create it.
- `POSTGRES_DB_USERNAME`: username.
- `POSTGRES_DB_PASSWORD`: password.
