etcd Maintenance Service#
To facilitate etcd maintenance, MKE 4k deploys the etcd maintenance host service on all controller nodes. The service is currently exposed only on localhost.
You configure the etcd maintenance service in the etcd section of the the
mke4.yaml configuration file:
etcd:
maintenanceService:
httpPort: <desired_http_port>
grpcPort: <desired_grpc_port>
User communication with the etcd service occurs through the HTTP port, the default for which is port 18088. Internal communication for
the service occurs through the GRPC port, the default for which is port
5557.
