nbi k8s #44

Supports: kubernetes

Deploy this charm on Kubernetes with the CLI. Find out how by reading the docs.

Description

A CAAS charm to deploy OSM's Northbound Interface (NBI).


Overview

NBI for Juju CAAS

Testing

The tests of this charm are done using tox and Zaza.

Prepare environment

The machine in which the tests are run needs access to a juju k8s controller. The easiest way to approach this is by executing the following commands:

sudo apt install tox -y
sudo snap install microk8s --classic
sudo snap install juju

microk8s.status --wait-ready
microk8s.enable storage dashboard dns

juju bootstrap microk8s k8s-cloud

If /usr/bin/python does not exist, you should probably need to do this:

sudo ln -s /usr/bin/python3 /usr/bin/python
