Customize readinessProbe and livenessProbe for Auto DevOps?
Apps deployed with Auto DevOps are currently getting health checked at /
path with predefined port and interval.
Per https://gitlab.com/charts/auto-deploy-app/blob/master/templates/deployment.yaml#L34
livenessProbe:
httpGet:
path: /
port: {{ .Values.service.internalPort }}
initialDelaySeconds: 15
timeoutSeconds: 15
readinessProbe:
httpGet:
path: /
port: {{ .Values.service.internalPort }}
initialDelaySeconds: 5
timeoutSeconds: 3
Health checking /
hits my Rail's database. And if the db is down, Kubernetes will see my pods as unhealthy and continuously tear down and start up my entire fleet, as described in https://thisdata.com/blog/making-a-rails-health-check-that-doesnt-hit-the-database.
Given that I want to setup my own health check path at /health_check
with a different initialDelaySeconds
that's more suitable for my app.
I got around this by duplicating Auto DevOps' Helm Chart and templates in my repo and modifying them to my needs. But then I miss out on all the constant improvements that GitLab is making to the chart, unless I watch for new commits like a hawk and import them frequently.
Is there any way to customize these settings without rolling my own copy of the chart?
