The new Beijing release scalability, resiliency, and manageablity are described here. These capabilities apply to the OOM/Kubernetes installation.
Installation
Follow the OOM installation instructions at
http://onap.readthedocs.io/en/latest/submodules/oom.git/docs/index.html
Overview of the running system
Healthchecks
Verify that the portal healtcheck passes by the robot framework:
portal-app Resiliency
A portal-app container failure can be simulated by stopping the portal-app container. The kubernetes liveness operation will detect that the ports are down, inferring there's a problem with the service, and in turn, will restart the container.
portal-app Scaling
To scale a new portal-app, set the replica count appropriately.
In our tests below, we are going to work with the OOM portal component in isolation. In this exercise, we scale the portal-app with 2 new replicas.
Check Portal UI and perform sanity tests.
- After 3 instances of Portal are up, edit IP in /etc/hosts file, and logon as demo user on http://portal.api.simpledemo.onap.org:8989/ONAPPORTAL/login.htm
- then killed 1 instance process_id=12345, I am able to continue on Portal page seamlessly
- another test on timing when killed all 3 instances, the Portal processes are coming up within 30 seconds
