docker-compose file to share for geonetwork version 3?

[d3netxer]

Does somebody have a docker-compose file to share for geonetwork version 3?

I would like to have it running along with NGINX and POSTGRES. I am only seeing docker files in the repo for geonetwork version 3.

You can use one of the files for version 4 and customise it.

Basically you will need to use the geonetwork:3-postgres image and define the POSTGRES_DB_USERNAME, POSTGRES_DB_PASSWORD, POSTGRES_DB_PORT, POSTGRES_DB_NAME and POSTGRES_DB_HOST environment variables in the GeoNetwork container to connect to the postgres database.

Thank you, this is the route I was thinking, and your comment is making me more confident. I will proceed.

I'm not really sure why I'm having problems, but it wasn't working for me today. I think the piece that wasn't working is routing to the public IP address...

However, I was able to successfully deploy using the H2 database. Here is my docker-compose.yml:

version: '3.1'
services:

 www:
    image: nginx
    ports:
      - 80:80
    volumes:
       - ./dev-env/nginx/nginx.conf:/etc/nginx/nginx.conf

 geonetwork:
    image: 'geonetwork:3.12.6'
    restart: always
    ports:
      - 8080:8080
    environment:
      DATA_DIR: /var/lib/geonetwork_data
    volumes:
      - geonetwork:/var/lib/geonetwork_data

volumes:
  geonetwork:

and here is my nginx.conf:

events {}
http {
server {
    listen       80;

    location / {
        proxy_pass   http://172.17.0.1:8080;
    }

}
}

I'm not really sure how in the 4x example GeoNetwork is able to host the application without doing the reverse-proxy I did, but I suspect it has something to do with the different services all being on the same network on the docker-compose file.

This works for me: docker-compose.yml

version: '3.1'
services:

 www:
    image: nginx
    ports:
      - 80:80
    volumes:
       - ./dev-env/nginx/nginx.conf:/etc/nginx/nginx.conf

 geonetwork:
    image: 'geonetwork:3.12.6'
    restart: always
    environment:
      DATA_DIR: /var/lib/geonetwork_data
    volumes:
      - geonetwork:/var/lib/geonetwork_data

volumes:
  geonetwork:

With this nginx.conf file:

events {
  worker_connections  4096;  ## Default: 1024
}

http {
  server {
    listen 80;

    access_log /var/log/nginx/gn-access.log;
    error_log /var/log/nginx/gn-error.log;

    location / {
      server_name_in_redirect off;
      return 301 /geonetwork;
    }

    location /geonetwork {
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header Host $http_host;
      proxy_set_header X-Forwarded-Proto https;
      proxy_redirect off;
      proxy_pass http://geonetwork:8080/geonetwork;
    }
  }
}

Thanks for sharing @juanluisrp.

I was working on docker compose the past few days, and I was able to come up with a configuration that let's me install GeoNetwork, GeoServer, along with them using PostGIS as a backend, and let me proxy them all using NGINX. Note that I am also using certbot to get a certificate and I am using SSH.

I will share below:

docker-compose.yml

version: '3.9'
