titlenetbox mS Capability [HELM Chart]

The work bellow is based on the following git repository, providing netbox docker images: https://github.com/ninech/netbox-docker

The Netbox helm chart has been submitted in OOM, the code can be found here: https://github.com/onap/oom/tree/master/kubernetes/contrib/charts/netbox

This helm chart is comprised of three subcharts, being:

  • netbox-app: provides the IPAM capability we're seeking for current selected use cases (vFW).
  • netbox-nginx: reverse proxy exposing IPAM system in a secure fashion (using NodePort).
  • netbox-postgress: backend database persisting the Netbox data. Currently a deployment, should be converted to statefull set using StorageClass.


Regarding the netbox-app, this charts come with possibility for customization. The folder tree structure is the following:

Code Block
.
??? config
    ??? configuration				Those are configuration scripts coming from Netbox itself, they remained un-touched.
    ?   ??? configuration.py
    ?   ??? gunicorn_config.py
    ?   ??? ldap_config.py
    ??? initializers				Those YAML files are where we can added so pre-provisioning data, such as user or custom fields.
    ?   ??? custom_fields.yml
    ?   ??? groups.yml
    ?   ??? users.yml
    ??? provisioning				This defines the entrypoint of netbox-app deployment, that will provision prefix to support vFW use case.
    ?   ??? provision.sh
    ??? startup_scripts				Those scripts are provided by Netbox itself, they remained un-touched.
        ??? 00_users.py
        ??? 10_groups.py
        ??? 20_custom_fields.py


In order to test Netbox locally using this helm chart, here are the steps to follow:

Code Block
git clone https://gerrit.onap.org/r/oom
cd oom/kubernetes
helm serve &
make contrib
helm install local/contrib --name netbox --namespace $NAMESPACE

This will result in installing the 3 charts, and run the job that will provisioned Netbox for us.

Ouput of the helm install should look like the following:

Code Block
$ helm install local/contrib --name netbox --namespace onap-adetalhouet
NAME:   netbox

titlenetbox mS Capability [pre-provisioning scripts]

Three main things are achived durig pre-provisioning:

  • Create an admin onap user, as follow. This is part of the netbbox-app chart resources file: config/initializers/users.yml.

    Code Block
    onap:
    first_name: Steve
    last_name: McQueen
    email: steve.mcqueen@onap.org
    password: onap123$
    api_token: onceuponatimeiplayedwithnetbox20180814
    is_staff: true # whether user is admin or not, default = false
    is_active: true # whether user is active, default = true
    is_superuser: true # Whether user has all edit rights or not, default = false

  • Create an custom_fields being client_key in order to uniquely identify the resource with a key generated by ONAP. This is part of the netbbox-app chart resources file: config/initializers/custom_fields.yml.

    Code Block
    external-key: 
  description: "The external-key uniquely identify the resources to a service within ONAP."
  filterable: true
  label: ONAP external key
  on_objects: 
    - ipam.models.IPAddress
  required: true
  type: text
  weight: 0
resource-name:
  description: "The resource-name of the element using this IP."
  filterable: true
  label: ONAP resource name
  on_objects:
    - ipam.models.IPAddress
  required: true
  type: text
  weight: 0
