locust status ready but 0 users

[4ss3g4f]

Locust docker installed and working, but when executed there is no users ??

Describe the bug

no users running for test

Expected behavior

users should be not 0 (zero)

version: '3.7'

networks:
  bridge:
    external: true

services:
  master:
    image: locustio/locust:latest
    deploy:
      replicas: 1
      # service restart policy
      restart_policy:
        condition: on-failure
        delay: 5s
        max_attempts: 3
        window: 120s
    ports:
     - "8089:8089"
    networks:
      - bridge
    volumes:
      - /home/core/locust:/mnt/locust
    command: -f /mnt/locust/locustfile.py --master -H http://192.168.33.231:8089

  worker:
    image: locustio/locust:latest
    networks:
      - bridge
    deploy:
      replicas: 3
      # service restart policy
      restart_policy:
        condition: on-failure
        delay: 5s
        max_attempts: 3
        window: 120s
    volumes:
      - /home/core/locust:/mnt/locust
    command: -f /mnt/locust/locustfile.py --worker --master-host 192.168.33.231:8089

I copy all files from https://github.com/locustio/locust/tree/master/examples to the docker yaml volume path,
and change ip 127.0.0.1 to 192.68.33.231

Why locust is not running ??

Have you checked the log (command line output) for master and workers?

I think you're making this too complicated. Here's my docker-compose.yml:

version: '3'

services:
  master:
    image: locustio/locust:1.2
    ports:
     - "8089:8089"
    volumes:
      - ./:/mnt/locust
      - ./locust:/usr/local/lib/python3.8/site-packages/locust
    command: -f /mnt/locust/locustfile.py --master -H http://target
    # command: -f /mnt/locust/locustfile.py --master -H http://target --step-load

  worker:
    image: locustio/locust:1.2
    volumes:
      - ./:/mnt/locust
      # - ./locust:/usr/local/lib/python3.8/site-packages/locust
    command: -f /mnt/locust/locustfile.py --worker --master-host master --loglevel DEBUG

  target:
    image: nginx:latest
    volumes:
      - ./nginx:/etc/nginx/conf.d/

Then to start with with 3 workers: docker-compose up --scale worker=3

@max-rocket-internet ,

Whats is the value of http://target ??
is it locust master node ip and port or it is the target domain which is going to be stresstest with locust ??

[max-rocket-internet]

Whats is the value of http://target ??

That's the container named target, it's in the YAML. You can use container names as hostnames in docker-compose. This container is the target of the load test.

I also encountered this problem in version 1.2.2, but the same code works fine in version 1.1.1

users should be not 0 (zero)

Your user count is 0 because your worker is not connected. You can see it Workers 0 in the screen shot. You should debug network communication between your workers and master.

@cyberw ,

Here are the master and worker logs from portainer,

@max-rocket-internet ,

yes i think you are right

version: '3.7'

networks:
  bridge:
    external: true

services:
  master:
    image: locustio/locust:latest

      restart_policy:
        condition: on-failure
        delay: 5s
        max_attempts: 3
        window: 120s
    ports:
     - "8089:8089"
    networks:
      - bridge
    volumes:
      - /home/core/locust:/mnt/locust
    command: -f /mnt/locust/locustfile.py --master -H http://www.google.com

  worker:
    image: locustio/locust:latest
    networks:
      - bridge
    deploy:
      replicas: 3
      # service restart policy
      restart_policy:
        condition: on-failure
        delay: 5s
        max_attempts: 3
        window: 120s
    volumes:
      - /home/core/locust:/mnt/locust
    command: -f /mnt/locust/locustfile.py --worker --master-host master

it should be connected between master and worker, i will check again. Thank you
