This image gives support for using PostgreSQL as database engine for geonetwork. When you start the container, a database is created, and it is populated by geonetwork, once it starts.
Please note that this image does not ship the postgres database server itself, but it gives you the option to link to a container running postgres, or to connect to a postgres instance using its ip address. If you are looking for a self-contained installation of geonetwork, including the database engine, please have a look at the default image variant.
In order to setup the connection from geonetwork, you must inject the following variables into the container: - POSTGRES_DB_USERNAME: postgres user on your database server (must have permission to create databases) - POSTGRES_DB_PASSWORD: postgres password on your database server
If your postgres instance is listening on a non-standard port, you must also set that variable: - POSTGRES_DB_PORT: postgres port on your database server (defaults to 5432)
Connecting to a postgres database
If you want to connect to a postgres server, you need to pass an extra environment variable, containing the IP address for this server (which could be localhost, if you are running it locally). - POSTGRES_DB_HOST: IP address of your database server
For instance, if the server is running on 192.168.1.10, on port 5434, the username is postgres and the password is mysecretpassword:
$ docker run --name geonetwork -d -p 8080:8080 -e POSTGRES_DB_HOST=192.168.1.10 -e POSTGRES_DB_PORT=5434 -e POSTGRES_DB_USERNAME=postgres -e POSTGRES_DB_PASSWORD=mysecretpassword geonetwork:postgres
If you want to 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:
$ docker network create --driver bridge mynet
Then if you want to run the official image of postgres, using $POSTGRES_DB_HOST as container name, you could launch it like this:
$ docker run --name $POSTGRES_DB_HOST --network=mynet -d postgres
And then you could launch geonetwork, making sure you join the same network, and setting the required environment variables, including the POSTGRES_DB_HOST:
$ docker run --name geonetwork -d -p 8080:8080 --network=mynet -e POSTGRES_DB_HOST=$POSTGRES_DB_HOST -e POSTGRES_DB_PORT=5432 -e POSTGRES_DB_USERNAME=postgres -e POSTGRES_DB_PASSWORD=mysecretpassword geonetwork:postgres
