Hi
*Question*
I'm wondering how to refresh the IP list in order to update subchannel
list, after creating gRPC channel in Ruby using DNS resolution (which
created several subchannels).
*Context*
I've setup gRPC communication between our services in a Kubernetes
environnement two years ago but we are facing issues after pods restart.
I've setup a Kubernetes headless service (in order to get all pod IPs from
the DNS).
I've managed to use load balancing with the following piece of code.
stub =
ExampleService::Stub.new("headless-test-grpc-master.test-grpc.svc.cluster.local:50051",
:this_channel_is_insecure, timeout: 5, channel_args: {'grpc.lb_policy_name'
=> 'round_robin'})
But when I create new pods after the connection or a reconnection, calls
are not load balanced on these new servers.
That why I'm wondering what should I do to make the gRPC resolver refresh
the list of IP and create expected new subchannels.
Is it something achievable? Which configuration should I use?
Thanks for your help
