External access required by the Charm

Depending on the configuration of the charm, the following external accesses are needed:

• Access to the PostgreSQL database (mandatory).
• Access to the S3 server is S3 is configured in the charm.
• Access to http://github.com to download Promtail if the logging interface is used in the charm.

If the option “external system avatars enabled” is enabled in the admin, access to https://avatars.discourse.org is necessary.

Besides that, other services, like link previews and installing themes from a git repository may need access to external sites to work, so allowing internet access to the Discourse instance is recommended. In restricted environments, the model-config options juju-http-proxy, juju-https-proxy and juju-no-proxy can be used to set up a proxy for Discourse, see Using proxies with Charmed Kubernetes for more information.
