Observation regarding AA server unavailability

[PrathibaJee]

When AA application goes down , Impact :

• OAM layer will be locked completely in all the applications.

Note :

• Once the application is back , operations will be resumed.
• The failure of this server can be identified either from the OL logs or by the response in the swagger UI.

Proposal for High availability :

Proposal#1 : If we are planning to continue with docker engine , a simple shell script that

• monitors the pid of the application’s port
• starts the container if the pid is not available (already we have such scripts for other applications like traffic checker. Monitoring dashboard)

Proposal#2 : If we are planning to move to an orchestrator(docker swarm, Kubernetes) then the orchestrator will take care of it.

Please refer the comment to get a view about the discussion for a similar topic in the EATL repository.

Currently CICD engineer included a High Availability script that monitors the PID of the containers and brings it back whenever it goes to unavailability. High level information about this script is available in this document .

Further keeping this issue open under milestone v2.0.0_impl to observe the applications availability in the version 2.0.0 implementation.
