netbox role

A role for setting up NetBox.
It automatically pulls in all required dependencies like Redis and PostgreSQL, deploys the provided systemd services and gunicorn config and sets up a PostgreSQL database named netbox with an owner named netbox and the specified password. However providing the NetBox configuration, setting up a web server like nginx to proxy to gunicorn and tasks like creating users, etc. you have to do yourself.

Supported Distributions

Should work on Debian-based distributions.

Required Arguments

• netbox__version: The NetBox version to deploy.
• netbox__db_password: The password to use for connection to the database. This is required since the upgrade script runs as root and therefore peer authentication doesn't work.
• netbox__config: The NetBox config to deploy. See NetBox Configuration for more infos.

Optional Arguments

• netbox__custom_pipeline_oidc_group_and_role_mapping: Whether or not to have custom pipeline code for OIDC group and role mapping present. See Custom Pipeline Code for OIDC Group and Role Mapping for more infos.
  Defaults to false.

NetBox Configuration

The NetBox configuration should include a connection to Redis as well as a connection to PostgreSQL.
Configuration for the Redis connection:

REDIS = {
    "tasks": {
      "HOST": "localhost",
      "PORT": 6379,
      "USERNAME": "",
      "PASSWORD": "",
      "DATABASE": 0,
      "SSL": False,
    },
    "caching": {
      "HOST": "localhost",
      "PORT": 6379,
      "USERNAME": "",
      "PASSWORD": "",
      "DATABASE": 1,
      "SSL": False,
    },
}

Configuration for the PostgreSQL connection:

DATABASE = {
  "HOST": "localhost",
  "NAME": "netbox",
  "USER": "netbox",
  "PASSWORD": "<same as netbox__db_password>",
}

Further configuration should take place. Some relevant resources can be found here:

• Installation guide configuration docs: https://netboxlabs.com/docs/netbox/en/stable/installation/3-netbox/#configuration
• Configuration docs: https://netboxlabs.com/docs/netbox/en/stable/configuration/
• Example configuration: https://github.com/netbox-community/netbox/blob/main/netbox/netbox/configuration_example.py

Web Server Setup

As this role just sets up gunicorn, but doesn't set up a web server, you need to do that yourself.
The relevant documentation on how to do that can be found here:

• Web server setup docs: https://netboxlabs.com/docs/netbox/en/stable/installation/5-http-server/
• Example base nginx config: https://github.com/netbox-community/netbox/blob/main/contrib/nginx.conf

Custom Pipeline Code for OIDC Group and Role Mapping

Setting the option netbox__custom_pipeline_oidc_group_and_role_mapping to true makes this role ensure custom pipeline code for OIDC group and role mapping is present. Note that this role uses code for NetBox >= 4.0.0.
The code is available in files/custom_pipeline_oidc_group_and_role_mapping.py, licensed under the CC BY-SA 4.0 license and taken from this authentik NetBox documentation. The documentation also shows how to use the pipeline code by defining a custom SOCIAL_AUTH_PIPELINE, which you also need to do, as the configuration isn't provided by this role. However instead of under netbox.custom_pipeline. the functions are available under netbox.custom_pipeline_oidc_mapping. with this role. See also the default settings.py for the default SOCIAL_AUTH_PIPELINE.
