In T339890, we made adjustments to the deployment settings of the recommendation-api-ng until we reached a state where it could run on LiftWing. In this task, our goal is to deploy the rec-api on the staging environment first. If everything goes smoothly, we will then deploy it to the production environment.

On IRC, @elukey advised that we use deploy2002 due to a recent datacenter switchover. The second attempt to deploy on staging returned:

I tried to sync and got the same error as Kevin mentioned above.
However I saw that a pod was created during the process which was failing with CrashLoopBackOff.
The only issue I saw was probes failing (via kubectl describe )
Normal Killing 4m16s kubelet Container recommendation-api-ng-main failed liveness probe, will be restarted Warning Unhealthy 4m6s (x4 over 4m36s) kubelet Liveness probe failed: dial tcp 10.194.61.146:8080: connect: connection refused Warning Unhealthy 3m56s (x11 over 4m43s) kubelet Readiness probe failed: Get "http://10.194.61.146:8080/": dial tcp 10.194.61.146:8080: connect: connection refused

The recommendation-api-ng has been successfully deployed on LiftWing staging:

Below are a few notes from @elukey:
- in staging we have a single VIP/LB endpoint so every time we don't have to add one etc. but the TLS config and the Istio routing config needs to be enabled
- for prod we'll need to add a dedicated LV/VIP endpoint (recommendation-api-ng.discovery.wmnet), elukey or Tobias will handle the task
