+## Configuring probes for Kubernetes using health checks
+
+Helm charts already configure the needed probes in kubernetes using the healthchecks, but you can override the configuration provided by **editing the file `/k8s/helm/<chart-folder>/values.yaml`**. You'll see a code like that:
+
+```yaml
+probes:
+  liveness:
+    path: /liveness
+    initialDelaySeconds: 10
+    periodSeconds: 15
+    port: 80
+  readiness:
+    path: /hc
+    timeoutSeconds: 5
+    initialDelaySeconds: 90
+    periodSeconds: 60
+    port: 80
+```
+
+You can remove a probe if you want or update its configuration. Default configuration is the same for all charts:
+
+* 10 seconds before k8s starts to test the liveness probe
+* 1 sec of timeout for liveness probe (**not configurable**)
+* 15 sec between liveness probes calls
+* 90 seconds before k8s starts to test the readiness probe
+* 5 sec of timeout for readiness probe
+* 60 sec between readiness probes calls
