[][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`, `http://[::1]` and `http://127.0.0.1`.
|

|
|
|
|
### 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.
|
|
* `DB_*`: Use a persistent database.
|
|
* `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.
|
|
|
|
### 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 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`
|
|
|
|

#### A Note On OpenShift
|
|
|
|
OpenShift usually is configured with specific restrictions regarding root users.
|
|
[Special care][openshift-root] has to be taken when building images for OpenShift.
|
|
The Docker Image that may be built using this project (and which is available on Docker Hub) might not yet run without further customization on OpenShift.
|
|
If you have this running on OpenShift, it would be nice if you could open a PR with the changes you needed to make.
|
|
Or if you didn't do any changes and it just worked, that you could confirm this so that we can remove this notice.
|
|

|
|
|
|
## 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.

## 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 -U $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'`.
|
|
|
|
### 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?
|
|
|
|
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
|
|
docker-compose rm -f netbox
|
|
docker-compose up -d netbox
|
|
```
|
|
|
|
## 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
|
|
```
|
|
|
|
## Tests
|
|
|
|
To run the test coming with Netbox, use the `docker-compose.test.yml` file as such:
|
|
|
|
```
|
|
$ docker-compose -f docker-compose.test.yml run --rm app
|
|
```
