# NetBox [NetBox](https://docs.netbox.dev/en/stable/) is an open-source web application that provides [IP address management (IPAM)](https://en.wikipedia.org/wiki/IP_address_management) and [data center infrastructure management (DCIM)](https://en.wikipedia.org/wiki/Data_center_management#Data_center_infrastructure_management) functionality. ## Dependencies This service requires the following other services: - a [Postgres](postgres.md) database - a [Redis](redis.md) data-store, installation details [below](#redis) - a [Traefik](traefik.md) reverse-proxy server ## Configuration To enable this service, add the following configuration to your `vars.yml` file and re-run the [installation](../installing.md) process: ```yaml ######################################################################## # # # netbox # # # ######################################################################## netbox_enabled: true netbox_hostname: mash.example.com netbox_path_prefix: /netbox # Put a strong secret below, generated with `pwgen -s 64 1` or in another way netbox_environment_variable_secret_key: '' # The following superuser will be created upon launch. netbox_environment_variable_superuser_name: your_username_here netbox_environment_variable_superuser_email: your.email@example.com # Put a strong secret below, generated with `pwgen -s 64 1` or in another way. # Changing the password subsequently will not affect the user's password. netbox_environment_variable_superuser_password: '' # Redis configuration, as described below ######################################################################## # # # /netbox # # # ######################################################################## ``` ### URL In the example configuration above, we configure the service to be hosted at `https://mash.example.com/netbox`. You can remove the `netbox_path_prefix` variable definition, to make it default to `/`, so that the service is served at `https://mash.example.com/`. ### Authentication If `netbox_environment_variable_superuser_*` variables are specified, NetBox will try to create the user (if missing). [Single-Sign-On](#single-sign-on-sso-integration) is also supported. ### Redis As described on the [Redis](redis.md) documentation page, if you're hosting additional services which require Redis on the same server, you'd better go for installing a separate Redis instance for each service. See [Creating a Redis instance dedicated to NetBox](#creating-a-redis-instance-dedicated-to-netbox). If you're only running NetBox on this server and don't need to use Redis for anything else, you can [use a single Redis instance](#using-the-shared-redis-instance-for-netbox). #### Using the shared Redis instance for NetBox To install a single (non-dedicated) Redis instance (`mash-redis`) and hook NetBox to it, add the following **additional** configuration: ```yaml ######################################################################## # # # redis # # # ######################################################################## redis_enabled: true ######################################################################## # # # /redis # # # ######################################################################## ######################################################################## # # # netbox # # # ######################################################################## # Base configuration as shown above # Point NetBox to the shared Redis instance netbox_environment_variable_redis_host: "{{ redis_identifier }}" netbox_environment_variable_redis_cache_host: "{{ redis_identifier }}" # Make sure the NetBox service (mash-netbox.service) starts after the shared Redis service (mash-redis.service) netbox_systemd_required_services_list_custom: - "{{ redis_identifier }}.service" # Make sure the NetBox container is connected to the container network of the shared Redis service (mash-redis) netbox_container_additional_networks_custom: - "{{ redis_identifier }}" ######################################################################## # # # /netbox # # # ######################################################################## ``` This will create a `mash-redis` Redis instance on this host. This is only recommended if you won't be installing other services which require Redis. Alternatively, go for [Creating a Redis instance dedicated to NetBox](#creating-a-redis-instance-dedicated-to-netbox). #### Creating a Redis instance dedicated to NetBox The following instructions are based on the [Running multiple instances of the same service on the same host](../running-multiple-instances.md) documentation. Adjust your `inventory/hosts` file as described in [Re-do your inventory to add supplementary hosts](../running-multiple-instances.md#re-do-your-inventory-to-add-supplementary-hosts), adding a new supplementary host (e.g. if `netbox.example.com` is your main one, create `netbox.example.com-deps`). Then, create a new `vars.yml` file for the `inventory/host_vars/netbox.example.com-deps/vars.yml`: ```yaml --- ######################################################################## # # # Playbook # # # ######################################################################## # Put a strong secret below, generated with `pwgen -s 64 1` or in another way # Various other secrets will be derived from this secret automatically. mash_playbook_generic_secret_key: '' # Override service names and directory path prefixes mash_playbook_service_identifier_prefix: 'mash-netbox-' mash_playbook_service_base_directory_name_prefix: 'netbox-' ######################################################################## # # # /Playbook # # # ######################################################################## ######################################################################## # # # redis # # # ######################################################################## redis_enabled: true ######################################################################## # # # /redis # # # ######################################################################## ``` This will create a `mash-netbox-redis` instance on this host with its data in `/mash/netbox-redis`. Then, adjust your main inventory host's variables file (`inventory/host_vars/netbox.example.com/vars.yml`) like this: ```yaml ######################################################################## # # # netbox # # # ######################################################################## # Base configuration as shown above # Point NetBox to its dedicated Redis instance netbox_environment_variable_redis_host: mash-netbox-redis netbox_environment_variable_redis_cache_host: mash-netbox-redis # Make sure the NetBox service (mash-netbox.service) starts after its dedicated Redis service (mash-netbox-redis.service) netbox_systemd_required_services_list_custom: - "mash-netbox-redis.service" # Make sure the NetBox container is connected to the container network of its dedicated Redis service (mash-netbox-redis) netbox_container_additional_networks_custom: - "mash-netbox-redis" ######################################################################## # # # /netbox # # # ######################################################################## ``` ### Single-Sign-On (SSO) integration NetBox supports different [Remote Authentication](https://docs.netbox.dev/en/stable/configuration/remote-authentication/) backends, including those provided by the [Python Social Auth](https://python-social-auth.readthedocs.io/) library. This library is included in the NetBox container image by default, so you can invoke any [backend](https://github.com/python-social-auth/social-core/tree/master/social_core/backends) provided by it. Each module's Python file contains detailed information about how to configure it. It should be noted that module-specific configuration is passed as Python configuration (via `netbox_configuration_extra_python`), and **not as environment variables**. We have detailed information about integrating with [Keycloak](keycloak.md) below. You can use the configuration in the [Keycloak section](#keycloak) as a template for configuring other backends. #### Keycloak To integrate with [Keycloak](keycloak.md) use the following **additional** configuration: ```yaml netbox_environment_variables_additional_variables: | REMOTE_AUTH_ENABLED=True REMOTE_AUTH_BACKEND=social_core.backends.keycloak.KeycloakOAuth2 # Space-separated names of groups that new users will be assigned to. # These groups must be created manually (from the Admin panel's Groups section) before use. REMOTE_AUTH_DEFAULT_GROUPS= netbox_configuration_extra_python: | # These need to match your Client app information in Keycloak. See below SOCIAL_AUTH_KEYCLOAK_KEY = '' SOCIAL_AUTH_KEYCLOAK_SECRET = '' # The value for this is retrieved from Keycloak -> Realm Settings -> Keys tab -> Public key button for RS256 SOCIAL_AUTH_KEYCLOAK_PUBLIC_KEY = '' # The value for these are retrieved from Keycloak -> Realm Settings -> General tab -> OpenID Endpoint Configuration button SOCIAL_AUTH_KEYCLOAK_AUTHORIZATION_URL = 'https://KEYCLOAK_URL/realms/REALM_IDENTIFIER/protocol/openid-connect/auth' SOCIAL_AUTH_KEYCLOAK_ACCESS_TOKEN_URL = 'https://KEYCLOAK_URL/realms/REALM_IDENTIFIER/protocol/openid-connect/token' # If Keycloak is running on the same server, uncomment the lines below # and replace HOSTNAME with the hostname of the Keycloak server (e.g. mash.example.com or keycloak.example.com). # netbox_container_extra_arguments: # - --add-host=HOSTNAME:{{ ansible_host }} ``` The Client app needs to be created and configured in a special way on the Keycloak side by: - activating **Client authentication** - **Valid redirect URIs**: `https://NETBOX_URL/oauth/complete/keycloak/` - **Web origins**: `https://NETBOX_URL/` - in **Advanced**, changing the following settings: - **Request object signature algorithm** = `RS256` - **User info signed response algorithm** = `RS256` - in **Client scopes** (for this Client app via the **Client scopes** tab, not for all apps via the left-most menu), configure the `*-dedicated` scope (e.g. `netbox-dedicated` if you named your Client app `netbox`) and in the **Mappers** tab, click **Configure a new mapper** add a new **Audience** mapper with the following settings: - **Name** = anything you like (e.g. `netbox-audience`) - **Included Client Audience** = the key of this Client app (e.g. `netbox`) - **Add to access token** = On For additional environment variables controlling groups and permissions for new users (like `REMOTE_AUTH_DEFAULT_GROUPS`), see the NetBox documentation for [Remote Authentication](https://docs.netbox.dev/en/stable/configuration/remote-authentication/). ## Installation If you've decided to install a dedicated Redis instance for NetBox, make sure to first do [installation](../installing.md) for the supplementary inventory host (e.g. `netbox.example.com-deps`), before running installation for the main one (e.g. `netbox.example.com`). ## Usage After installation, you can go to the NetBox URL, as defined in `netbox_hostname` and `netbox_path_prefix`. You can log in with the **username** (**not** email) and password specified in the `netbox_environment_variable_superuser*` variables.
