When Egress is not working as expected

1. Confirm egress is enabled

Confirm egress is enabled by verifying the value for the enableEgress key in the osm-mesh-config MeshConfig custom resource. osm-mesh-config resides in the namespace OSM control plane namespace, osm-system by default.

# Returns true if egress is enabled
$ kubectl get meshconfig osm-mesh-config -n osm-system -o jsonpath='{.spec.traffic.enableEgress}{"\n"}'

The above command must return a boolean string (true or false) indicating if egress is enabled.

2. Inspect OSM controller logs for errors

# When osm-controller is deployed in the osm-system namespace
kubectl logs -n osm-system $(kubectl get pod -n osm-system -l app=osm-controller -o jsonpath='{.items[0].metadata.name}')

Errors will be logged with the level key in the log message set to error:


3. Confirm the Envoy configuration

Confirm the Envoy proxy configuration on the client has a default egress filter chain on the outbound listener. Refer to the sample configurations to verify that the client is configured to have outbound access to external destinations.
