Can hyperledger-fabric get the peer node running status without entering the docker container?

Question

Can hyperledger-fabric get the peer node running status without entering the docker container? If so, how should I get it?

Answer 1

In docker-compose file, for peer service add following env variable. (You may add a different port for different services)

- CORE_OPERATIONS_LISTENADDRESS=0.0.0.0:9440

expose the port(You may expose port number as per availability). Export different port for different peer

ports:
  - 9440:9440

Once all services up hit the following path for specific service(As per port defined)

curl -X GET localhost:9440/healthz

You will get a following response if the service is running.

    {
      "status": "OK",
      "time": "2009-11-10T23:00:00Z"
    }

If service is not available, you will get the following response.

 {
  "status": "Service Unavailable",
  "time": "2009-11-10T23:00:00Z",
  "failed_checks": [
    {
      "component": "docker",
      "reason": "failed to connect to Docker daemon: invalid endpoint"
    }
  ]
}
