Netbox Docker

Ansible role to configure Netbox as a docker-compose project.

Installation

Install this role with Ansible Galaxy:

ansible-galaxy install git+https://github.com/wastrachan/ansible-role-netbox-docker.git

Local Installation

If you'd like to include this role directly in a playbook, set your roles_path to ./roles via environment variable or ansible.cfg.

Then, add this role to your playbook's requirements.yml:

- src: https://github.com/wastrachan/ansible-role-netbox-docker
  version: master
  name: netbox-docker

And finally, install the role with Ansible Galaxy:

ansible-galaxy install -r requirements.yml

Requirements

docker and docker-compose must be available and installed on the target system.

Role Variables

Configuration and installation options are made available as variables. Some of these (secret_key, passwords) must be overridden before use!

Example Playbook

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:

- hosts: servers
  roles:
    - netbox-docker

TLS for localhost

Developing locally and testing TLS (i.e. https) features often poses a challenge. This guide is intended for people developing with, on or for NetBox or NetBox Docker on their computer. It allows to access NetBox Docker through TLS on https://localhost:443, https://127.0.0.1:443 and https://[::1]:443. It is based on the setup recommended by the Netbox-Docker wiki on TLS. First install mkcert on your computer. It creates and installs a local CA-Certificate, which will be used by mkcert to create and sign other certificates. This way, your certificates are trusted on your own computer and you don't get a TLS warning in your tools (browsers, cURL, and so forth).

Begin by creating the certificates for localhost and it's IPv4 and IPv6 addresses using the following commands.

mkcert -install
mkcert localhost 127.0.0.1 ::1

This should have created a file called localhost+2.pem and another file called localhost+2-key.pem. Use these two certificates with a slight modification of the setup proposed above:

- hosts: localhost
  vars:
    netbox_port: null
    netbox_use_caddy: true
    netbox_ssl_cert_bundle: path_to/localhost+2.pem
    netbox_ssl_cert_key: path_to/localhost+2-key.pem
  roles:
    - netbox-docker

Traefik/nginx-proxy Support

This playbook can be used with traefik or jwilder's nginx-proxy by adding labels with netbox_container_labels, or environment variables with netbox_container_env, respectively. Additionally, netbox_additional_network_names will attach the netbox service to additional networks, as traefik/nginx-proxy usually reside in a network other than that created by docker-compose projects. While not a complete guide to these services, your configuration may look like the below:

traefik

netbox_port: null
netbox_additional_network_names:
  - traefik
netbox_container_labels:
  traefik.enable: "true"
  traefik.http.services.netbox.loadbalancer.server.port: "8080"
  traefik.http.routers.netbox.rule: "Host(`netbox.domain.com`)"

nginx-proxy

netbox_port: null
netbox_additional_network_names:
  - nginx
netbox_container_env:
  VIRTUAL_HOST: netbox.domain.com
  VIRTUAL_PORT: "8080"
