I was setting up hyperledger caliper to test a fabcar network and got ECONNREFUFUSED error multiple times. It said that it failed to enroll admin. I setup the test network using ./startFabric.sh javascript in fabcar repo of fabric-samples. Then I used docker-compose to start caliper( used docker-compose up in caliper-benchmarks ). This is the docker-compose file that I used:

version: '2'

services:
    caliper:
        container_name: caliper
        image: hyperledger/caliper:0.3.2
        command: launch master --caliper-flow-only-test --caliper-fabric-gateway-usegateway --caliper-fabric-gateway-discovery 
        environment:
        - CALIPER_BIND_SUT=fabric:2.1.0
        - CALIPER_BENCHCONFIG=benchmarks/samples/fabric/fabcar/config1.yaml
        - CALIPER_NETWORKCONFIG=networks/fabric/network-config.yaml
        volumes:
        - ~/caliper-benchmarks:/hyperledger/caliper/workspace
        networks:
          - net_test

networks:
  net_test:
    external: "true"

This was my network-config.yaml file:


name: Fabric
version: "1.0"
mutual-tls: false

caliper:
    blockchain: fabric
    #command:
        #start: export FABRIC_VERSION=2.1.0;export FABRIC_CA_VERSION=1.4.4;docker-compose -f networks/fabric/naman/docker-compose/2org1peercouchdb_solo_raft/docker-compose-tls.yaml up -d;sleep 3s
        #end: docker-compose -f networks/fabric/naman/docker-compose/2org1peercouchdb_solo_raft/docker-compose-tls.yaml down;(test -z \"$(docker ps -aq)\") || docker rm $(docker ps -aq);(test -z \"$(docker images dev* -q)\") || docker rmi $(docker images dev* -q);rm -rf /tmp/hfc-*

I was using fabric 2.1.0 and caliper 0.3.2. I specified net-test in docker-compose to make sure caliper container is in the same network as fabric. Can someone please help?

    You've set the CA endpoints as localhost. Because you are running containerized caliper localhost is not available. You need to use the service name instead of localhost, expose the ports in docker-compose, and make sure both caliper and your fabric components are running on the same docker network. – lindluni Jul 04 '20 at 19:15
  • @lindluni where do I get the service name from ? – Naman Gupta Jul 05 '20 at 07:35
  • In the docker-compose file, under services, its just the name of each stanza, so if you look at your caliper compose file, under services, the entry is named `caliper` that would be how you would refer to it. So for other services you refer to them by the same name you declared under the services section in your docker-compose file. But just remember, they need to be on the same docker network – lindluni Jul 06 '20 at 04:33
  • @lindluni I changed localhost to caliper in the url for certifacate authorities.... I got the following error: ``` error: [FabricCAClientService.js]: Failed to enroll admin, error:%o message=Calling enrollment endpoint failed with error [Error: connect ECONNREFUSED 172.18.0.12:7054], stack=Error: Calling enrollment endpoint failed with error [Error: connect ECONNREFUSED 172.18.0.12:7054] ``` On inspecting net_test(network on which fabric is running) it does not show me a caliper container but on inspecting the caliper container it shows me its running on "net_test" network mode. – Naman Gupta Jul 06 '20 at 07:58
