# netbox-docker
|
|
|
|
[][travis]
|
|
|
|
This repository houses the components needed to build NetBox as a Docker container.
|
|
Images built using this code are released to [Docker Hub][netbox-dockerhub] every night.
|
|
|
|
[travis]: https://travis-ci.org/ninech/netbox-docker
|
|
[netbox-dockerhub]: https://hub.docker.com/r/ninech/netbox/tags/
|
|
|
|
## Quickstart
|
|
|
|
To get NetBox up and running:
|
|
|
|
```
|
|
$ git clone -b master https://github.com/ninech/netbox-docker.git
|
|
$ cd netbox-docker
|
|
$ docker-compose pull
|
|
$ docker-compose up -d
|
|
```
|
|
|
|
The application will be available after a few minutes.
|
|
Use `docker-compose port nginx 8080` to find out where to connect to.
|
|
|
|
```
|
|
$ echo "http://$(docker-compose port nginx 8080)/"
|
|
http://0.0.0.0:32768/
|
|
|
|
# Open netbox in your default browser on macOS:
|
|
$ open "http://$(docker-compose port nginx 8080)/"
|
|
|
|
# Open netbox in your default browser on (most) linuxes:
|
|
$ xdg-open "http://$(docker-compose port nginx 8080)/" &>/dev/null &
|
|
```
|
|
|
|
Alternatively, use something like [Reception][docker-reception] to connect to _docker-compose_ projects.
|
|
|
|
Default credentials:
|
|
|
|
* Username: **admin**
|
|
* Password: **admin**
|
|
* API Token: **0123456789abcdef0123456789abcdef01234567**
|

|
## Dependencies
|
|
|
|
This project relies only on *Docker* and *docker-compose* meeting this requirements:
|
|
|
|
* The *Docker version* must be at least `1.13.0`.
|
|
* The *docker-compose version* must be at least `1.10.0`.
|
|
|
|
To ensure this, compare the output of `docker --version` and `docker-compose --version` with the requirements above.
|
|
|
|
## Configuration
|
|
|
|
You can configure the app using environment variables.
|
|
These are defined in `netbox.env`.
|
|
Read [Environment Variables in Compose][compose-env] to understand about the various possibilities to overwrite these variables.
|
|
(The easiest solution being simply adjusting that file.)
|
|
|
|
To find all possible variables, have a look at the [configuration.docker.py][docker-config] and [docker-entrypoint.sh][entrypoint] files.
|
|
Generally, the environment variables are called the same as their respective NetBox configuration variables.
|
|
Variables which are arrays are usually composed by putting all the values into the same environment variables with the values separated by a whitespace ("` `").
|
|
For example defining `ALLOWED_HOSTS=localhost ::1 127.0.0.1` would allows access to NetBox through `http://localhost:8080`, `http://[::1]:8080` and `http://127.0.0.1:8080`.
|
|
|
|
[compose-env]: https://docs.docker.com/compose/environment-variables/
|
|
|
|
### Production
|
|
|
|
The default settings are optimized for (local) development environments.
|
|
You should therefore adjust the configuration for production setups, at least the following variables:
|
|
|
|
* `ALLOWED_HOSTS`: Add all URLs that lead to your NetBox instance, space separated. E.g. `ALLOWED_HOSTS=netbox.mycorp.com server042.mycorp.com 2a02:123::42 10.0.0.42 localhost ::1 127.0.0.1` (It's good advice to always allow localhost connections for easy debugging, i.e. `localhost ::1 127.0.0.1`.)
|
|
* `DB_*`: Use your own persistent database. Don't use the default passwords!
|
|
* `EMAIL_*`: Use your own mailserver.
|
|
* `MAX_PAGE_SIZE`: Use the recommended default of 1000.
|
|
* `SUPERUSER_*`: Only define those variables during the initial setup, and drop them once the DB is set up. Don't use the default passwords!
|
|
* `REDIS_*`: Use your own persistent redis. Don't use the default passwords!
|
|
|
|
### Running on Docker Swarm / Kubernetes / OpenShift
|
|
|
|
You may run this image in a cluster such as Docker Swarm, Kubernetes or OpenShift, but this is advanced level.
|
|
|
|
In this case, we encourage you to statically configure NetBox by starting from [NetBox's example config file][default-config], and mounting it into your container in the directory `/etc/netbox/config/` using the mechanism provided by your container platform (i.e. [Docker Swarm configs][swarm-config], [Kubernetes ConfigMap][k8s-config], [OpenShift ConfigMaps][openshift-config]).
|
|
|
|
But if you rather continue to configure your application through environment variables, you may continue to use [the built-in configuration file][docker-config].
|
|
We discourage storing secrets in environment variables, as environment variable are passed on to all sub-processes and may leak easily into other systems, e.g. error collecting tools that often collect all environment variables whenever an error occurs.
|
|
|
|
Therefore we *strongly advise* to make use of the secrets mechanism provided by your container platform (i.e. [Docker Swarm secrets][swarm-secrets], [Kubernetes secrets][k8s-secrets], [OpenShift secrets][openshift-secrets]).
|
|
[The configuration file][docker-config] and [the entrypoint script][entrypoint] try to load the following secrets from the respective files.
|
|
If a secret is defined by an environment variable and in the respective file at the same time, then the value from the environment variable is used.
|
|
|
|
* `SUPERUSER_PASSWORD`: `/run/secrets/superuser_password`
|
|
* `SUPERUSER_API_TOKEN`: `/run/secrets/superuser_api_token`
|
|
* `DB_PASSWORD`: `/run/secrets/db_password`
|
|
* `SECRET_KEY`: `/run/secrets/secret_key`
|
|
* `EMAIL_PASSWORD`: `/run/secrets/email_password`
|
|
* `NAPALM_PASSWORD`: `/run/secrets/napalm_password`
|
|
* `REDIS_PASSWORD`: `/run/secrets/redis_password`
|
|
|
|
Please also consider [the advice about running NetBox in production](#production) above!

|
### NAPALM Configuration
|
|
|
|
Since v2.1.0 NAPALM has been tightly integrated into NetBox.
|
|
NAPALM allows NetBox to fetch live data from devices and return it to a requester via its REST API.
|
|
To learn more about what NAPALM is and how it works, please see the documentation from the [libary itself][napalm-doc] or the documentation from [NetBox][netbox-napalm-doc] on how it is integrated.
|
|
|
|
To enable this functionality, simply complete the following lines in `netbox.env` (or appropriate secrets mechanism) :
|
|
|
|
* `NAPALM_USERNAME`: A common username that can be utilized for connecting to network devices in your environment.
|
|
* `NAPALM_PASSWORD`: The password to use in combintation with the username to connect to network devices.
|
|
* `NAPALM_TIMEOUT`: A value to use for when an attempt to connect to a device will timeout if no response has been recieved.
|
|
|
|
However, if you don't need this functionality, leave these blank.
|

|
|
|
|
### Custom Initialization Code (e.g. Automatically Setting Up Custom Fields)
|
|
|
|
When using `docker-compose`, all the python scripts present in `/opt/netbox/startup_scripts` will automatically be executed after the application boots in the context of `./manage.py`.
|
|
|
|
That mechanism can be used for many things, e.g. to create NetBox custom fields:
|
|
|
|
```python
|
|
# docker/startup_scripts/load_custom_fields.py
|
|
from django.contrib.contenttypes.models import ContentType
|
|
from extras.models import CF_TYPE_TEXT, CustomField
|
|
|
|
from dcim.models import Device
|
|
from dcim.models import DeviceType
|
|
|
|
device = ContentType.objects.get_for_model(Device)
|
|
device_type = ContentType.objects.get_for_model(DeviceType)
|
|
|
|
my_custom_field, created = CustomField.objects.get_or_create(
|
|
type=CF_TYPE_TEXT,
|
|
name='my_custom_field',
|
|
description='My own custom field'
|
|
)
|
|
|
|
if created:
|
|
my_custom_field.obj_type.add(device)
|
|
my_custom_field.obj_type.add(device_type)
|
|
```
|
|
|
|
#### Initializers
|
|
|
|
Initializers are built-in startup scripts for defining NetBox custom fields, groups and users.
|
|
All you need to do is to mount you own `initializers` folder ([see `docker-compose.yml`][netbox-docker-compose]).
|
|
Look at the [`initializers` folder][netbox-docker-initializers] to learn how the files must look like.
|
|
|
|
Here's an example for defining a custom field:
|
|
|
|
```yaml
|
|
# initializers/custom_fields.yml
|
|
text_field:
|
|
type: text
|
|
label: Custom Text
|
|
description: Enter text in a text field.
|
|
required: false
|
|
filter_logic: loose
|
|
weight: 0
|
|
on_objects:
|
|
- dcim.models.Device
|
|
- dcim.models.Rack
|
|
- ipam.models.IPAddress
|
|
- ipam.models.Prefix
|
|
- tenancy.models.Tenant
|
|
- virtualization.models.VirtualMachine
|
|
```

|
|
|
|
#### Custom Docker Image
|
|
|
|
You can also build your own NetBox Docker image containing your own startup scripts, custom fields, users and groups
|
|
like this:
|
|
|
|
```
|
|
ARG VERSION=latest
|
|
FROM ninech/netbox:$VERSION
|
|
|
|
COPY startup_scripts/ /opt/netbox/startup_scripts/
|
|
COPY initializers/ /opt/netbox/initializers/
|
|
```
|
|
|
|
## Netbox Version
|
|
|
|
The `docker-compose.yml` file is prepared to run a specific version of NetBox.
|
|
To use this feature, set the environment-variable `VERSION` before launching `docker-compose`, as shown below.
|
|
`VERSION` may be set to the name of
|
|
[any tag of the `ninech/netbox` Docker image on Docker Hub][netbox-dockerhub].
|
|
|
|
```
|
|
$ export VERSION=v2.2.6
|
|
$ docker-compose pull netbox
|
|
$ docker-compose up -d
|
|
```
|
|
|
|
You can also build a specific version of the NetBox image. This time, `VERSION` indicates any valid
|
|
[Git Reference][git-ref] declared on [the 'digitalocean/netbox' Github repository][netbox-github].
|
|
Most commonly you will specify a tag or branch name.
|
|
|
|
```
|
|
$ export VERSION=develop
|
|
$ docker-compose build --no-cache netbox
|
|
$ docker-compose up -d
|
|
```
|
|
|
|
Hint: If you're building a specific version by tag name, the `--no-cache` argument is not strictly necessary.
|
|
This can increase the build speed if you're just adjusting the config, for example.

|
[netbox-github]: https://github.com/digitalocean/netbox/releases
|
|
|
|
### LDAP enabled variant
|
|
|
|
The images tagged with "-ldap" contain anything necessary to authenticate against an LDAP or Active Directory server.
|
|
The default configuration `ldap_config.py` is prepared for use with an Active Directory server.
|
|
Custom values can be injected using environment variables, similar to the main configuration mechanisms.
|
|
|
|
## Troubleshooting
|
|
|
|
This section is a collection of some common issues and how to resolve them.
|
|
If your issue is not here, look through [the existing issues][issues] and eventually create a new issue.
|
|
|
|
[issues]: (https://github.com/ninech/netbox-docker/issues)
|
|
|
|
### Docker Compose basics
|
|
|
|
* You can see all running containers belonging to this project using `docker-compose ps`.
|
|
* You can see the logs by running `docker-compose logs -f`.
|
|
Running `docker-compose logs -f netbox` will just show the logs for netbox.
|
|
* You can stop everything using `docker-compose stop`.
|
|
* You can clean up everything using `docker-compose down -v --remove-orphans`. **This will also remove any related data.**
|
|
* You can enter the shell of the running NetBox container using `docker-compose exec netbox /bin/bash`. Now you have access to `./manage.py`, e.g. to reset a password.
|
|
* To access the database run `docker-compose exec postgres sh -c 'psql -U $POSTGRES_USER $POSTGRES_DB'`
|
|
* To create a database backup run `docker-compose exec postgres sh -c 'pg_dump -cU $POSTGRES_USER $POSTGRES_DB' | gzip > db_dump.sql.gz`
|
|
* To restore that database backup run `gunzip -c db_dump.sql.gz | docker exec -i $(docker-compose ps -q postgres) sh -c 'psql -U $POSTGRES_USER $POSTGRES_DB'`.
|
|
|
|
### Nginx doesn't start
|
|
|
|
As a first step, stop your docker-compose setup.
|
|
Then locate the `netbox-nginx-config` volume and remove it:
|
|
|
|
```bash
|
|
# Stop your local netbox-docker installation
|
|
$ docker-compose down
|
|
|
|
# Find the volume
|
|
$ docker volume ls | grep netbox-nginx-config
|
|
local netbox-docker_netbox-nginx-config
|
|
|
|
# Remove the volume
|
|
$ docker volume rm netbox-docker_netbox-nginx-config
|
|
netbox-docker_netbox-nginx-config
|
|
```
|
|
|
|
Now start everything up again.
|
|
|
|
If this didn't help, try to see if there's anything in the logs indicating why nginx doesn't start:
|
|
|
|
```bash
|
|
$ docker-compose logs -f nginx
|
|
```
|
|
|
|
### Getting a "Bad Request (400)"
|
|
|
|
> When connecting to the NetBox instance, I get a "Bad Request (400)" error.
|
|
|
|
This usually happens when the `ALLOWED_HOSTS` variable is not set correctly.
|
|
|
|
### How to upgrade
|
|
|
|
> How do I update to a newer version of netbox?
|
|
|
|
It should be sufficient to pull the latest image from Docker Hub, stopping the container and starting it up again:
|
|
|
|
```bash
|
|
docker-compose pull netbox
|
|
docker-compose stop netbox netbox-worker
|
|
docker-compose rm -f netbox netbox-worker
|
|
docker-compose up -d netbox netbox-worker
|
|
```
|
|
|
|
### Webhooks don't work
|
|
|
|
First make sure that the webhooks feature is enabled in your Netbox configuration and that a redis host is defined.
|
|
Check `netbox.env` if the following variables are defined:
|
|
|
|
```
|
|
WEBHOOKS_ENABLED=true
|
|
REDIS_HOST=redis
|
|
```
|
|
|
|
Then make sure that the `redis` container and at least one `netbox-worker` are running.
|
|
|
|
```
|
|
# check the container status
|
|
$ docker-compose ps
|
|
|
|
Name Command State Ports
|
|
--------------------------------------------------------------------------------------------------------
|
|
netbox-docker_netbox-worker_1 /opt/netbox/docker-entrypo ... Up
|
|
netbox-docker_netbox_1 /opt/netbox/docker-entrypo ... Up
|
|
netbox-docker_nginx_1 nginx -c /etc/netbox-nginx ... Up 80/tcp, 0.0.0.0:32776->8080/tcp
|
|
netbox-docker_postgres_1 docker-entrypoint.sh postgres Up 5432/tcp
|
|
netbox-docker_redis_1 docker-entrypoint.sh redis ... Up 6379/tcp
|
|
|
|
# connect to redis and send PING command:
|
|
$ docker-compose run --rm -T redis sh -c 'redis-cli -h redis -a $REDIS_PASSWORD ping'
|
|
Warning: Using a password with '-a' option on the command line interface may not be safe.
|
|
PONG
|
|
```
|
|
|
|
If `redis` and the `netbox-worker` are not available, make sure you have updated your `docker-compose.yml` file!
|
|
|
|
Everything's up and running? Then check the log of `netbox-worker` and/or `redis`:
|
|
|
|
```bash
|
|
docker-compose logs -f netbox-worker
|
|
docker-compose logs -f redis
|
|
```
|
|
|
|
Still no clue? You can connect to the `redis` container and have it report any command that is currently executed on the server:
|
|
|
|
```bash
|
|
docker-compose run --rm -T redis sh -c 'redis-cli -h redis -a $REDIS_PASSWORD monitor'
|
|
|
|
# Hit CTRL-C a few times to leave
|
|
```
|
|
|
|
If you don't see anything happening after you triggered a webhook, double-check the configuration of the `netbox` and the `netbox-worker` containers and also check the configuration of your webhook in the admin interface of Netbox.
|
|
|
|
### Breaking Changes
|
|
|
|
From time to time it might become necessary to re-engineer the structure of this setup.
|
|
Things like the `docker-compose.yml` file or your Kubernetes or OpenShift configurations have to be adjusted as a consequence.
|
|
Since April 2018 each image built from this repo contains a `NETBOX_DOCKER_PROJECT_VERSION` label.
|
|
You can check the label of your local image by running `docker inspect ninech/netbox:v2.3.1 --format "{{json .ContainerConfig.Labels}}"`.
|
|
Compare the version with the list below to check whether a breaking change was introduced with that version.
|
|
|
|
The following is a list of breaking changes of the `netbox-docker` project:
|
|
|
|
* 0.4.0: In order to use Netbox webhooks you need to add Redis and a netbox-worker to your docker-compose.yml.
|
|
* 0.3.0: Field `filterable: <boolean` was replaced with field `filter_logic: loose/exact/disabled`. It will default to `CF_FILTER_LOOSE=loose` when not defined.
|
|
* 0.2.0: Re-organized paths: `/etc/netbox -> /etc/netbox/config` and `/etc/reports -> /etc/netbox/reports`. Fixes [#54](https://github.com/ninech/netbox-docker/issues/54).
|
|
* 0.1.0: Introduction of the `NETBOX_DOCKER_PROJECT_VERSION`. (Not a breaking change per se.)
|
|
|
|
## Rebuilding & Publishing images
|
|
|
|
`./build.sh` is used to rebuild the Docker image:
|
|
|
|
```
|
|
$ ./build.sh --help
|
|
Usage: ./build.sh <branch> [--push]
|
|
branch The branch or tag to build. Required.
|
|
--push Pushes built Docker image to docker hub.
|
|
|
|
You can use the following ENV variables to customize the build:
|
|
BRANCH The branch to build.
|
|
Also used for tagging the image.
|
|
DOCKER_REPO The Docker registry (i.e. hub.docker.com/r/DOCKER_REPO/netbox)
|
|
Also used for tagging the image.
|
|
Default: ninech
|
|
SRC_REPO Which fork of netbox to use (i.e. github.com/<SRC_REPO>/netbox).
|
|
Default: digitalocean
|
|
URL Where to fetch the package from.
|
|
Must be a tar.gz file of the source code.
|
|
Default: https://github.com/${SRC_REPO}/netbox/archive/$BRANCH.tar.gz
|
|
```
|
|
|
|
### Publishing Docker Images
|
|
|
|
New Docker Images are built and published every 24h by using travis:

## Tests
|
|
|
|
To run the tests coming with NetBox, use the `docker-compose.yml` file as such:
|
|
|
|
```
|
|
$ docker-compose run netbox ./manage.py test
|
|
```
