Overview
In CircleCI Server, the services are managed as Kubernetes deployments.
This article shows you how you can re-deploy these services via Kubernetes.
Check deployments
We can list all deployments and their statuses via:
kubectl -n <namespace> get deployment
Restart a specific deployment
You can restart a specific deployment like this:
kubectl -n <namespace> rollout restart deployment frontend deployment.apps/frontend restarted
Restart deployments using layer labels
Multiple deployments (or statefulsets) can also be restarted using labels, eg)
kubectl -n <namespace> rollout restart deployment -l layer=application
CircleCI Server deployments and statefulset are currently labelled with layer application for front-end pods, database (for back-end such as Postgres or MongoDB or execution (nomad
Outcome
You can verify by inspecting the age of the pods:
% kubectl get pods -n circleci -l app=frontend NAME READY STATUS RESTARTS AGE frontend-5b8c9764d5-pz9pl 1/1 Running 0 2m26s
