Netbox-SSOT

Netbox-ssot is a small but powerful microservice designed to keep your Netbox instance in sync with external data sources.

It is designed to be run as a cronjob, and will periodically update Netbox with the latest data from the external sources. It syncs each source in parallel to speed up the process of syncing.

Currently, the supported external data sources types are:

• ovirt
• vmware
• dnac
• proxmox
• paloalto
  • PAN-OS firewall
• fortigate
• fmc
• ios-xe
  • All devices with ios-xe supporting netconf

Warning

This project is still under heavy development, use with caution.

• v1.x.x works with netbox>=4.0.0

• v0.x.x works with netbox>=3.7.0

Configuration

Netbox-ssot is configured via a single yaml file. The configuration file is divided into three sections:

• logger: Logger configuration
• netbox: Netbox configuration
• source: Array of configuration for each data source

Example configuration can be found here.

Logger

Parameter	Description	Type	Possible values	Default	Required
logger.level	Log level	int	0-3	1	Yes
logger.dest	Log output filename. Default "" representing stdout.	str	Any valid path	""	No

Netbox

Parameter	Description	Type	Possible values	Default	Required
netbox.apiToken	Netbox API token.	str	Any valid token	""	Yes
netbox.hostname	Hostname of your netbox instance (e.g netbox.example.com).	str	Valid hostname	""	Yes
netbox.port	Port of your netbox instance.	int	0-65536	443	No
netbox.httpScheme	HTTP scheme of your netbox instance.	str	[http, https]	https	No
netbox.validateCert	Validate the TLS certificate of your netbox instance.	bool	[true, false]	false	No
netbox.timeout	Max timeout for api call of your netbox instance.	int	>=0	30	No
netbox.removeOrphans	If set to true all objects, marked with netbox-ssot tag that were not found during this iteration are automatically deleted. If set to false, objects that were not found are marked with an Orphan tag. We can then use netbox.removeOrphansAfterDays to remove the orphans after n days that they were not seen on the sources.	bool	[true, false]	true	No
netbox.removeOrphansAfterDays	Specifies the number of days to wait before automatically deleting objects marked as Orphan. This setting is only applicable if netbox.removeOrphans is set to false. A value of 5 means objects are deleted in five days after being marked as Orphan and not found since.	int	>0	MaxInt	No
netbox.tag	Tag to be applied to all objects managed by netbox-ssot.	string	any	"netbox-ssot"	No
netbox.tagColor	TagColor for the netbox-ssot tag.	string	any	"07426b"	No

Deployment

Via docker

docker run -v /path/to/config.yaml:/app/config.yaml ghcr.io/bl4ko/netbox-ssot

Via k8s

Create k8s secret from self defined config.yaml:

kubectl create secret generic netbox-ssot-secret --from-file=config.yaml

Apply cronjob with custom settings:

kubectl apply -f cronjob.yaml

Using self signed certificate

Create self signed certificate e.g.:

kubectl create secret generic netbox-ssot-cert --from-file=sub.pem=./sub.pem

Use cronjob with cert mounted:

kubectl apply -f cronjob_with_cert.yaml
