Operator Troubleshooting

Contour Operator runs in a Kubernetes cluster and is managed by a Deployment resource. The following steps can be used to verify and troubleshoot the operator:

Verify the operator deployment is available:

$ kubectl get deploy/contour-operator -n contour-operator
NAME               READY   UP-TO-DATE   AVAILABLE   AGE
contour-operator   1/1     1            1           39m

Check the logs of the operator:

$ kubectl logs deploy/contour-operator -n contour-operator -c contour-operator -f

...

When a Contour is created, the operator should successfully reconcile the object:

...
2020-12-01T00:10:15.341Z	INFO	controllers.Contour	reconciling	{"request": "default/contour-sample"}
...
2020-12-01T00:10:15.442Z	DEBUG	controller	Successfully Reconciled	{"reconcilerGroup": "operator.projectcontour.io", "reconcilerKind": "Contour", "controller": "contour", "name": "contour-sample", "namespace": "default"}

Check the status of your Contour resource:

$ kubectl get contour/contour-sample -o yaml
apiVersion: operator.projectcontour.io/v1alpha1
kind: Contour
metadata:
  name: contour-sample
  namespace: default
...
status:
  availableContours: 2
  availableEnvoys: 1
  conditions:
  - lastTransitionTime: "2020-12-01T00:55:38Z"
    message: Contour has minimum availability.
    reason: ContourAvailable
    status: "True"
    type: Available

If the Contour does not become available, check the status of operands.

$ kubectl get po -n projectcontour
NAME                       READY   STATUS      RESTARTS   AGE
contour-7649c6f6cc-9hxn9   1/1     Running     0          6m18s
contour-7649c6f6cc-sb4nn   1/1     Running     0          6m18s
contour-certgen-vcsqd      0/1     Completed   0          6m18s
envoy-qshxf                2/2     Running     0          6m18s

Check the logs of the operands. The following example checks the logs of the contour deployment operand:

$ kubectl logs deploy/contour -n projectcontour -c contour -f

Note: projectcontour is the default namespace used by operands of a Contour when spec.namespace.name is unspecified.
