Upgrade a GeoNode 4.0 4.1 instance to GeoNode 4.2

GeoNode 4.2 introduces some changes to the required environmental variable for the Docker services, and a few changes to the Nginx configuration.

Changes to the .env file

Here below the changes between the template .env files are reported. Not all of them are strictly required, but it's better to have them aligned.

Of course, you will have to replace the placeholders with your values where changes are required:

• {{project_name}}: this placeholder must be replaced with the value you have set for COMPOSE_PROJECT_NAME
• {siteurl}: this placeholder must be replaced with the value you have set for SITE_URL
• GEONODE_DATABASE_USER: password of the application DB. By default, it's the same as the project name (COMPOSE_PROJECT_NAME variable)
• GEONODE_GEODATABASE_USER: password of the data DB. By default, it's the same as the project name (COMPOSE_PROJECT_NAME variable)

Changes to Nginx configuration

Replace the geonode.conf.envsubst file, which in a default Docker setup is located under /var/lib/docker/volumes/{{project_name}}-nginxconfd/_data/sites-enabled, with the updated version:

The major changes in this configuration are

• Jenkins is not automatically setup by default in GeoNode 4.2
• Nginx communities with Django over the proxy_pass protocol instead of uwsgi
