lae.netbox
Deploys and configures NetBox, an IP address management (IPAM) and data center infrastructure management (DCIM) tool.
This role will deploy NetBox within its own virtualenv either by release tarball or via git using uWSGI as the application server.
Tested and supported against CentOS 7/Debian 9 and 10/Ubuntu 16, 18 and 20.
Note that this role is slightly opinionated and differs from installation instructions from the NetBox documentation. The main differences are:
-
Uses distro-provided systemd instead of supervisord
-
Uses uWSGI as an application server instead of gunicorn
-
Hardens the NetBox/uWSGI service (see
templates/netbox.service.j2
) -
Will hot reload on upgrades and configuration changes
Quickstart
Provided you have Ansible installed and are using defaults:
ansible-galaxy install geerlingguy.postgresql davidwittman.redis lae.netbox
ansible-playbook -i your.server.fqdn, ~/.ansible/roles/lae.netbox/examples/playbook_single_host_deploy.yml -K
This will deploy NetBox and PostgreSQL on your.server.fqdn
; once complete it
should be accessible on port 80. Modify if needed. Read below for more insight.
You can also use Vagrant, if you prefer, to bring up NetBox at localhost:8080
:
ansible-galaxy install geerlingguy.postgresql davidwittman.redis lae.netbox
cd ~/.ansible/roles/lae.netbox/
vagrant up
Support/Contributing
If you would like to contribute to this role, please read DEVELOPING.md
for
this repository’s workflow and (optional) instructions on setting up a
development environment. This role uses the lae.travis-lxc
role when testing
under Travis CI, which you can find definitions for in the tests/
directory.
For support or if you’d like to contribute to this role but want guidance, feel free to ask in @lae’s Discord server: https://discord.gg/cjqr6Fg
Prerequisites
PostgreSQL
This role does not setup a PostgreSQL server (but will create a database if needed), so you’ll need to setup a PostgreSQL server and create a database user separate from this role. Take a look at the Example Playbook section.
|
NetBox v2.2.0+ require PostgreSQL 9.4 at the minimum, which may not be available in your distribution’s repos. You may want to use a role for this. |
Redis
This role does not setup or manage a Redis instance. You may want to either
install redis-server
via a task in pre_tasks
within your playbook or use a
Redis installation role such as
DavidWittman.redis.
|
NetBox v2.9.0+ require Redis 4.0 at the minimum. The role suggested above defaults to a 2.8 version, so make sure you specify a newer version in a role variable or deploy Redis 4.0+ another way. |
Role Variables
|
See examples/ for some playbooks you could write for different scenarios.
|
|
A few role variables are mandatory. Look for the bold required below. |
netbox_stable: false
netbox_git: false
It’s required to set one of the above variables to true
. netbox_stable
tells the role to deploy by extracting tarball releases from GitHub, while
netbox_git
tells the role to clone a NetBox git repository - they’re mutually
exclusive.
netbox_stable_version: 2.9.9
netbox_stable_uri: "https://github.com/netbox-community/netbox/archive/v{{ netbox_stable_version }}.tar.gz"
These can be configured to pin a version (e.g. increment to trigger an upgrade) or deploy using a tarball located somewhere else. Useful for when you need to modify something in a release or are deploying locally behind a firewall.
netbox_git_version: develop
netbox_git_uri: "https://github.com/netbox-community/netbox.git"
netbox_git_version
can be any valid ref within a git repository.
netbox_git_uri
can be used to point to e.g. an on-premise repo or a fork.
netbox_superuser_username: admin
#netbox_superuser_password: changeme
netbox_superuser_email: admin@localhost
It is required to set the superuser password. This role will create a new superuser if the user does not exist, or will modify an existing user if they’re not a superuser/have a different email or password. (Yes, you can use this to reset your superuser password if you forget it.)
netbox_database: netbox
netbox_database_user: netbox
#netbox_database_password: changeme
#netbox_database_host: localhost
netbox_database_port: 5432
#netbox_database_socket: /var/run/postgresql
It is required to configure either a socket directory (to communicate over UNIX sockets) or a host/password (to use TCP/IP). See the Example Playbook section for more information on configuring the database.
Note that these are used to configure DATABASE
in configuration.py
.
netbox_database_conn_age: 300
To configure Netbox to keep database connections open longer than a single requests,
set netbox_database_conn_age
to your preferred maximum connection age, in seconds.
300 seconds (5 minutes) is typically a good number to start with.
netbox_redis_host: 127.0.0.1
netbox_redis_port: 6379
netbox_redis_password: ''
netbox_redis_database: 0
netbox_redis_default_timeout: 300
netbox_redis_ssl_enabled: false
netbox_redis_cache_host: "{{ netbox_redis_host }}"
netbox_redis_cache_port: "{{ netbox_redis_port }}"
netbox_redis_cache_database: 1
netbox_redis_cache_password: "{{ netbox_redis_password }}"
netbox_redis_cache_default_timeout: "{{ netbox_redis_default_timeout }}"
netbox_redis_cache_ssl_enabled: "{{ netbox_redis_ssl_enabled }}"
This populates the REDIS
config dictionary in configuration.py
. Utilize the
second set of variables if you wish to seperate your cache database from your
webhooks database.
netbox_config:
#SECRET_KEY:
ALLOWED_HOSTS:
- localhost
- 127.0.0.1
#NAPALM_USERNAME:
#NAPALM_PASSWORD:
MEDIA_ROOT: "{{ netbox_shared_path }}/media"
REPORTS_ROOT: "{{ netbox_shared_path }}/reports"
SCRIPTS_ROOT: "{{ netbox_shared_path }}/scripts"
This is a dictionary of settings used to template NetBox’s configuration.py
.
See Mandatory Settings
and Optional Settings
from the NetBox documentation for more details, as well as
examples/netbox_config.yml
in this repository.
It is not necessary to define SECRET_KEY
here - this role will automatically
create one for you at {{ netbox_shared_path }}/generated_secret_key
. The
SECRET_KEY
will then be read from this file on subsequent runs, unless you
later do set this in your playbook. Note that you should define the
SECRET_KEY
if you are deploying multiple NetBox instances behind one load
balancer.
If you have enabled NAPALM integration in this role, you will need to configure NAPALM credentials here as well.
MEDIA_ROOT
/REPORTS_ROOT
/SCRIPTS_ROOT
, while not mandatory in the NetBox
documentation, is mandatory in this role to prevent losing these files during
upgrades (this role does not upgrade NetBox in-place). It should be set to a
directory that is permanent and not lost on upgrade (the default, listed above,
can be used without issue). This role will attempt to create these directories
and change their ownership to whatever netbox_user
is set to.
netbox_scripts: []
netbox_reports: []
Scripts
and Reports
to upload for use within NetBox. These should be lists of dictionaries with a
src
attribute, specifying the local path to the script or report, and a
name
attribute, specifying the module name (script/report name). For example:
## Example
netbox_scripts:
- src: netbox_scripts/migrate_application.py
name: migrate_application
netbox_reports:
- src: netbox_reports/devices.py
name: devices
This will copy netbox_scripts/migrate_application.py
from your playbook
directory to {{ netbox_config.SCRIPTS_ROOT }}/migrate_application.py
and
netbox_reports/devices.py
to {{ netbox.config.REPORTS_ROOT }}/devices.py
.
netbox_pip_packages: []
## Example:
netbox_pip_packages:
- https://github.com/steffann/netbox-example-plugin.git
- netbox-topology-views
This is a list of extra packages to install via pip
within NetBox'
virtualenv. You can specify any valid artifact that pip
understands.
If you list any plugins here, be sure to include the appropriate plugin
configurations within the netbox_config
role variable. Read
Plugins for more info.
netbox_user: netbox
netbox_group: netbox
netbox_home: /srv/netbox
netbox_releases_path: "{{ netbox_home }}/releases"
netbox_git_repo_path: "{{ netbox_releases_path }}/git-repo"
netbox_git_deploy_path: "{{ netbox_releases_path }}/git-deploy"
netbox_stable_path: "{{ netbox_releases_path }}/netbox-{{ netbox_stable_version }}"
netbox_current_path: "{{ netbox_home }}/current"
netbox_shared_path: "{{ netbox_home }}/shared"
These are all deployment details that you can modify to change the application
user and application storage locations. netbox_releases_path
stores all
NetBox releases you’ve ever deployed. netbox_git_repo_path
is where the Git
repository will be cloned to and should remain untouched - whilst
netbox_git_deploy_path
is where a git archive
using the ref
netbox_git_version
will be extracted to. netbox_stable_path
is the
extracted folder from a release tarball. netbox_current_path
will be
symlinked to the selected release and used in service/configuration files as
the location NetBox is installed. netbox_shared_path
is intended to store
configuration files and other "shared" content, like logs.
netbox_socket: "127.0.0.1:8000"
netbox_protocol: http
netbox_processes: "{{ ansible_processor_vcpus }}"
netbox_socket
defines what the uWSGI service will bind to and can be set to
any valid ListenStream
address (systemd socket). Set netbox_protocol
to uwsgi
if you want uWSGI to
speak WSGI (for instance if you’re running nginx as a load balancer).
netbox_processes
defines how many NetBox workers uWSGI will bring up to serve
requests.
netbox_application_log: "file:{{ netbox_shared_path }}/application.log"
netbox_requests_log: "file:{{ netbox_shared_path }}/requests.log"
These define where logs will be stored. You can use external logging facilities
instead of local files if you wish,
as
long as uWSGI supports it. Application log correlates to logger
and
requests log to req-logger
.
netbox_ldap_enabled: false
netbox_ldap_config_template: netbox_ldap_config.py.j2
Toggle netbox_ldap_enabled
to true
to configure LDAP authentication for
NetBox. netbox_ldap_config_template
should be the path to your template - by
default, Ansible will search your playbook’s templates/
directory for this.
You can find an example in examples/
. You will also need to set
netbox_config.REMOTE_AUTH_BACKEND
to netbox.authentication.LDAPBackend
.
netbox_napalm_enabled: false
netbox_napalm_packages:
- napalm
Toggle netbox_napalm_enabled
to enable NAPALM integration in NetBox. You must
define NAPALM_USERNAME
and NAPALM_PASSWORD
in the netbox_config
variable
to be able to use NAPALM. Add extra NAPALM python libraries by listing them in
netbox_napalm_packages
(e.g. napalm-eos
).
netbox_metrics_enabled: false
Toggle netbox_metrics_enabled
to true
to enable application metrics (via
django-prometheus). This adds
relevant pieces of configuration for proper metrics handling.
(more
info).
netbox_metrics_dir: netbox_metrics
netbox_metrics_path: "/run/{{ netbox_metrics_dir }}"
The directory name where the metrics files are stored can be set with
netbox_metrics_dir
. However, netbox_metrics_path
must remain the default
(seen above) in order to work with systemd
and the RuntimeDirectory
parameter (which only points to /run
).
netbox_keep_uwsgi_updated: false
Toggle netbox_keep_uwsgi_updated
to true
if you wish to ensure your uwsgi
server is the latest release, otherwise uwsgi will not be updated on subsequent
runs of your playbook.
netbox_uwsgi_options: {}
Specify extra configuration options to insert into uwsgi.ini
here. This is
expected to be a dictionary of key/value pairs, e.g. buffer-size: 65535
.
netbox_install_epel: true
Toggle netbox_install_epel
to false
if you do not want this role to install
the Fedora EPEL for you. This can be useful for enterprise environments where
the system’s repositories are managed/mirrored by the enterprise.
netbox_packages: []
netbox_python_packages: []
netbox_python_binary: /usr/bin/python{{ some version }}
netbox_ldap_packages: []
These variables are dynamically generated based on the target distribution. You
can check the defaults for these underneath the vars/
directory. You can use
these variables to target an unsupported operating system (although feel free
to open a PR to add in support!) or to specify a custom Python interpreter
(such as PyPy) to be used for deployment. Although, please note that support by
this role may be limited for alternative Python installations.
Example Playbook
The following installs PostgreSQL and creates a user with @geerlingguy’s robust Postgres role, then proceeds to deploy and configure NetBox using a local unix socket to talk to the Postgres server with the default netbox database user.
- hosts: netbox.idolactiviti.es
become: yes
roles:
- geerlingguy.postgresql
- davidwittman.redis
- lae.netbox
vars:
netbox_stable: true

Note the CREATEDB
attribute.
Assuming you have a PG server already running with the user netbox_prod_user
created, it owns a database called netbox_prod
, and it allows the host you’re
installing NetBox on to authenticate with it over TCP:
- hosts: netbox.idolactiviti.es
become: yes
