Hello,
after successful test of traefik load balancing configuration (https://learn.hashicorp.com/tutorials/nomad/load-balancing-traefik), when traefik retrieve instance information using consul provider,
I decided to try with service mesh (https://learn.hashicorp.com/tutorials/nomad/consul-service-mesh#run-a-connect-enabled-job) configuration, following the tutorial I discover that I can’t reach services that registered in consul by nomad because some consul health-check’s was failing:
also I do not see any port listeners for instances (ip:port) that are registered in consul, future investigation lead me to envoyproxy container log with following information:
[warning][config] [bazel-out/k8-opt/bin/source/common/config/_virtual_includes/grpc_stream_lib/common/config/grpc_stream.h:87] gRPC config stream closed: 3, Envoy 1.11.2 is too old and is not supported by Consul
not sure if that’s the root cause of my problem, but based on used image version, it seems to be triggered here:
future investigation shows that used envoy version are not supported by latest (1.9) consul:
can this “warning” be a reason for failing connection?
can I overtake this situation somehow or I need to downgrade to consul 1.8.6 for now?
Thanks.
