# NetBox
[NetBox](https://netbox.readthedocs.io/) is an IP address management (IPAM) and
data center infrastructure management (DCIM) tool.
## TL;DR
```shell
$ helm repo add bootc https://charts.boo.tc
$ helm install netbox \
--set postgresql.auth.postgresPassword=[password1] \
--set postgresql.auth.password=[password2] \
--set redis.auth.password=[password3] \
bootc/netbox
```
⚠️ **WARNING:** Please see [Production Usage](#production-usage) below before using this chart for real.
## Prerequisites
- Kubernetes 1.25.0+ (a [current](https://kubernetes.io/releases/) version)
- Helm 3.10.0+ (a version [compatible](https://helm.sh/docs/topics/version_skew/) with your cluster)
- This chart works with NetBox 3.5.0+ (3.6.4+ recommended)
## Installing the Chart
To install the chart with the release name `my-release` and default configuration:
```shell
$ helm repo add bootc https://charts.boo.tc
$ helm install my-release \
--set postgresql.auth.postgresPassword=[password1] \
--set postgresql.auth.password=[password2] \
--set redis.auth.password=[password3] \
bootc/netbox
```
The default configuration includes the required PostgreSQL and Redis database
services, but both should be managed externally in production deployments; see below.
### Production Usage
Always [use an existing Secret](#using-an-existing-secret) and supply all
passwords and secret keys yourself to avoid Helm re-generating any of them for
you.
I strongly recommend setting both `postgresql.enabled` and `redis.enabled` to
`false` and using a separate external PostgreSQL and Redis instance. This
de-couples those services from the chart's bundled versions which may have
complex upgrade requirements. I also recommend using a clustered PostgreSQL
server (e.g. using Zalando's
[Postgres Operator](https://github.com/zalando/postgres-operator)) and Redis
with Sentinel (e.g. using [Aaron Layfield](https://github.com/DandyDeveloper)'s
[redis-ha chart](https://github.com/DandyDeveloper/charts/tree/master/charts/redis-ha)).
Set `persistence.enabled` to `false` and use the S3 `storageBackend` for object
storage. This works well with Minio or Ceph RGW as well as Amazon S3. See [Using extraConfig for S3 storage configuration](#using-extraconfig-for-s3-storage-configuration) and [Persistent storage pitfalls](#persistent-storage-pitfalls), below.
Run multiple replicas of the NetBox web front-end to avoid interruptions during
upgrades or at other times when the pods need to be restarted. There's no need
to have multiple workers (`worker.replicaCount`) for better availability. Set
up `affinity.podAntiAffinity` to avoid multiple NetBox pods being colocated on
the same node, for example:
```yaml
affinity:
podAntiAffinity:
requiredDuringSchedulingIgnoredDuringExecution:
- labelSelector:
matchLabels:
app.kubernetes.io/instance: netbox
app.kubernetes.io/name: netbox
app.kubernetes.io/component: netbox
topologyKey: kubernetes.io/hostname
```
## Uninstalling the Chart
To delete the chart:
```shell
$ helm delete my-release
```
## Upgrading
### Bundled PostgreSQL
When upgrading or changing settings and using the bundled Bitnami PostgreSQL
sub-chart, you **must** provide the `postgresql.auth.password` at minimum.
Ideally you should also supply the `postgresql.auth.postgresPassword` and,
if using replication, the `postgresql.auth.replicationPassword`. Please see the
[upstream documentation](https://github.com/bitnami/charts/tree/master/bitnami/postgresql#upgrading)
for further information.
### From 4.x to 5.x
* NetBox has been updated to 3.6.4, but older 3.5+ versions should still work (this is not tested or supported, however).
* **Potentially breaking changes:**
* The `jobResultRetention` setting has been renamed `jobRetention` to match the change in NetBox 3.5.
* The `remoteAuth.backend` setting has been renamed `remoteAuth.backends` and is now an array.
* The `remoteAuth.autoCreateUser` setting now defaults to `false`.
* NAPALM support has been moved into a plugin since NetBox 3.5, so all NAPALM configuration has been **removed from this chart**.
* Please consult the [NetBox](https://docs.netbox.dev/en/stable/release-notes/) and [netbox-docker](https://github.com/netbox-community/netbox-docker) release notes in case there are any other changes that may affect your configuration.
* The Bitnami [PostgreSQL](https://github.com/bitnami/charts/tree/main/bitnami/postgresql) sub-chart was upgraded from 10.x to 13.x; please read the upstream upgrade notes if you are using the bundled PostgreSQL.
* The Bitnami [Redis](https://github.com/bitnami/charts/tree/main/bitnami/redis) sub-chart was upgraded from 15.x to 18.x; please read the upstream upgrade notes if you are using the bundled Redis.
### From 3.x to 4.x
* NetBox 3.0.0 or above is required
* The Bitnami [Redis](https://github.com/bitnami/charts/tree/master/bitnami/redis) sub-chart was upgraded from 12.x to 15.x; please read the upstream upgrade notes if you are using the bundled Redis
* The `cacheTimeout` and `releaseCheck.timeout` settings were removed
### From 2.x to 3.x
* NetBox 2.10.4 or above is required
* Kubernetes 1.14 or above is required
* Helm v3 or above is now required
* The `netbox` Deployment selectors are changed, so the Deployment **must** be deleted on upgrades
* The Bitnami [PostgreSQL](https://github.com/bitnami/charts/tree/master/bitnami/postgresql) sub-chart was upgraded from 8.x to 10.x; please read the upstream upgrade notes if you are using the bundled PostgreSQL
* The Bitnami [Redis](https://github.com/bitnami/charts/tree/master/bitnami/redis) sub-chart was upgraded from 10.x to 12.x; please read the upstream upgrade notes if you are using the bundled Redis
* The NGINX container is removed, on account of upstream's migration from Gunicorn to NGINX Unit
* The `webhooksRedis` configuration key in `values.yaml` has been renamed to `tasksRedis` to match the upstream name
* The `redis_password` key in the Secret has been renamed to `redis_tasks_password`
### From 1.x to 2.x
If you use an external Redis you will need to update your configuration values
due to the chart reflecting upstream changes in how it uses Redis. There are
now separate Redis configuration blocks for webhooks and for caching, though
they can both point at the same Redis instance as long as the database numbers
are different.
### From 0.x to 1.x
The chart dependencies on PostgreSQL and Redis have been upgraded, so you may
need to take action depending on how you have configured the chart. The
PostgreSQL chart was upgraded from 5.x.x to 7.x.x, and Redis from 8.x.x to
9.x.x.

## Persistent storage pitfalls
Persistent storage for media is enabled by default, but unless you take special
care you will run into issues. The most common issue is that one of the NetBox
pods gets stuck in the `ContainerCreating` state. There are several ways around
this problem:
1. For production usage I recommend **disabling** persistent storage by setting
`persistence.enabled` to `false` and using the S3 `storageBackend`. This can
be used with any S3-compatible storage provider including Amazon S3, Minio,
Ceph RGW, and many others. See further down for an example of this.
2. Use a `ReadWriteMany` volume that can be mounted by several pods across
nodes simultaneously.
3. Configure pod affinity settings to keep all the pods on the same node. This
allows a `ReadWriteOnce` volume to be mounted in several pods at the same
time.
4. Disable persistent storage of media altogether and just manage without. The
storage functionality is only needed to store uploaded image attachments.
To configure the pod affinity to allow using a `ReadWriteOnce` volume you can
use the following example configuration:
```yaml
affinity:
podAffinity:
requiredDuringSchedulingIgnoredDuringExecution:
- labelSelector:
matchLabels:
app.kubernetes.io/name: netbox
topologyKey: kubernetes.io/hostname
housekeeping:
affinity:
podAffinity:
requiredDuringSchedulingIgnoredDuringExecution:
- labelSelector:
matchLabels:
app.kubernetes.io/name: netbox
topologyKey: kubernetes.io/hostname
worker:
affinity:
podAffinity:
requiredDuringSchedulingIgnoredDuringExecution:
- labelSelector:
matchLabels:
app.kubernetes.io/name: netbox
topologyKey: kubernetes.io/hostname
```
## Using an Existing Secret
Rather than specifying passwords and secrets as part of the Helm release values,
you may pass these to NetBox using a pre-existing `Secret` resource. When using
this, the `Secret` must contain the following keys:
| Key | Description | Required? |
| -----------------------|---------------------------------------------------------------|---------------------------------------------------------------------------------------------------|
| `db_password` | The password for the external PostgreSQL database | If `postgresql.enabled` is `false` and `externalDatabase.existingSecretName` is unset |
| `email_password` | SMTP user password | Yes, but the value may be left blank if not required |
| `ldap_bind_password` | Password for LDAP bind DN | If `remoteAuth.enabled` is `true` and `remoteAuth.backend` is `netbox.authentication.LDAPBackend` |
| `redis_tasks_password` | Password for the external Redis tasks database | If `redis.enabled` is `false` and `tasksRedis.existingSecretName` is unset |
| `redis_cache_password` | Password for the external Redis cache database | If `redis.enabled` is `false` and `cachingRedis.existingSecretName` is unset |
| `secret_key` | Django secret key used for sessions and password reset tokens | Yes |
| `superuser_password` | Password for the initial super-user account | Yes |
| `superuser_api_token` | API token created for the initial super-user account | Yes |
## Using extraConfig for S3 storage configuration
If you want to use S3 as your storage backend and not have the config in the `values.yaml` (credentials!)
you can use an existing secret that is then referenced under the `extraConfig` key.
The secret would look like this:
```yaml
apiVersion: v1
kind: Secret
metadata:
labels:
app.kubernetes.io/instance: netbox
name: netbox-extra
stringData:
s3-config.yaml: |
STORAGE_CONFIG:
AWS_S3_ENDPOINT_URL:
AWS_S3_REGION_NAME:
AWS_STORAGE_BUCKET_NAME:
AWS_ACCESS_KEY_ID:
AWS_SECRET_ACCESS_KEY:
```
And the secret then has to be referenced like this:
```yaml
extraConfig:
- secret: # same as pod.spec.volumes.secret
secretName: netbox-extra
```
