SOLVED: "Error code 3: Failed to connect to 0.0.0.0:5000" about vroom-docker

[gisops-bot]

Ah cool thanks! That should make it into the readme actually

[nilsnolde]

Can you share how you setup the OSRM and vroom instances? If it's all in one docker-compose, see this comment (and also the README points that out): #27 (comment)

[AndreRoss92]

Hi, I set them up separrately by running the following commands

docker run -t -i -p 5000:5000 -v "${PWD}:/data" osrm/osrm-backend osrm-routed --algorithm mld /data/italy-latest.osrm

docker run -dt --name vroom -p 3000:3000 -v $PWD/conf:/conf -e VROOM_ROUTER=osrm vroomvrp/vroom-docker:v1.9.0

[nilsnolde]

ok, then it's more appropriate in the docker repo.

In your case: if you run vroom as described in the README, it'll do what you expect:
https://github.com/VROOM-Project/vroom-docker#vroom-docker-image

hint: --net host is important.

[AndreRoss92]

Thank you @nilsnolde ,

I had already tried with --net host, and running the same python script gives me the following error instead

[nilsnolde]

if you do curl --fail http://localhost:3000/health on the host machine? Probably works with localhost instead of local IP ;) not kidding.. not much of a networking guy, but I've had issues like that before, seems a lot of libs/apps treat the 2 subtly different.

[nilsnolde]

Oh seems you're on Windows.. Just visit http://localhost:3000/health in your browser then. If you get simple blank page without an error it can talk to vroom.

[AndreRoss92]

both with curl and visiting http://localhost:3000/healt is failing

[nilsnolde]

hm, then it needs to be some windows specific problem.. both

docker run -dt --name vroom -p 3000:3000 -v $PWD/conf:/conf -e VROOM_ROUTER=osrm vroomvrp/vroom-docker:v1.9.0
docker run -dt --name vroom --net host -v $PWD/conf:/conf -e VROOM_ROUTER=osrm vroomvrp/vroom-docker:v1.9.0

are working for me on linux. I can quickly check next time I'm on Win.

[AndreRoss92]

Thanks @nilsnolde

I made a couple of test and the results are the following

With docker run -dt --name vroom -p 3000:3000 -v $PWD/conf:/conf -e VROOM_ROUTER=osrm vroomvrp/vroom-docker:v1.9.0 -> I can access localhost:3000 successfully, but I get the "failed to connect to 0.0.0.0:5000" in Python

With docker run -dt --name vroom --net host -v $PWD/conf:/conf -e VROOM_ROUTER=osrm vroomvrp/vroom-docker:v1.9.0 -> localhost:3000 doesn't work at all

[AndreRoss92]

@AndreRoss92 I'm having the same issue!
Can't figure how to use docker-compose.yml, can you please explain?
I have copied it into config.yml and restart docker but nothing, still getting {"code":3,"error":"Failed to connect to 0.0.0.0:5000"}
I guess it's not working like this.
OSRM docker image is working fine through localhost:5000
Any help will be welcome.
Thank you

[nilsnolde]

Can you copy your config.yml and docker-compose.yml @constantineh ? And how are you running OSRM?

[constantineh]

Hi @nilsnolde,
I tried to use the following docker-compose.yml (same as provided to get started with my country data for osrm) but I'm getting an error regarding the "host". Any suggestions to fix the issue?
I will also try to modify and use the docker-compose provided above by @AndreRoss92.

ERROR: for host "host" network_mode is incompatible with port_bindings

can't express it better tbh. either or, can't use both.

Docker Compose is now in the Docker CLI, try docker compose up interesting, didn't know it was integrated now!

[constantineh]

@nilsnolde can you explain a bit more what you mean "either or, can't use both" ?
I'm quite new at docker and trying to figure it out...
Thank you

[nilsnolde]

    container_name: host
    ports:
      - 5000:5000

they can't go together.

e.g. https://forums.docker.com/t/docker-errors-invalidargument-host-network-mode-is-incompatible-with-port-bindings/103492 or lots of other forums articles when you google that error message.

[constantineh]

@nilsnolde finally I was able to fix the issue using the latest docker-compose.yml
Not sure why I had in vroom service container_name: host and also port: -3000:3000 😏

Here is my docker-compose.yml

version: "2.4"
services:
  vroom:
    network_mode: host
    image: vroomvrp/vroom-docker:v1.10.0
    container_name: vroom
    volumes:
      - ./vroom-conf/:/conf
    environment:
      - VROOM_ROUTER=osrm # router to use, osrm, valhalla or ors
    depends_on:
      - osrm

  # EXAMPLE for OSRM, please consult the repo for details: https://hub.docker.com/r/osrm/osrm-backend/
  osrm:
    image: osrm/osrm-backend
    container_name: osrm
    restart: always
    ports:
      - 5000:5000
    volumes:
      - ./osrm:/data
    command: "osrm-routed --max-matching-size 1000 --max-table-size 1000 --max-viaroute-size 1000 --algorithm mld /data/cyprus-latest.osrm"

OSRM works fine if I call for example:
curl "http://localhost:5000/route/v1/driving/33.375698,35.155582;33.375698,35.152795?steps=true"

However, if I run vroom, for example:

curl --header "Content-Type:application/json" --data '{  "vehicles": [
    {
      "id": 1,
      "start": [33.33480,35.07207],
      "end": [33.33480,35.07207],
      "capacity": [14],
      "skills": [0],
      "time_window": [0, 28800]
    }
  ],
  "shipments": [
    {
      "amount": [1],
      "skills": [0],
      "pickup": {
        "id": 2,
        "service": 90,
        "location": [33.32342,35.07401]
      },
      "delivery": {
        "id": 3,
        "service": 90,
        "location": [33.32795,35.08159]
      }
    }
  ],"options":{"g":true}}' http://localhost:3000/

I have as a response:
curl: (7) Failed to connect to localhost port 3000: Connection refused

Also, if I leave in vroom service ports: - 3000:3000 and run docker-compose I get as a response:

[nilsnolde]

Hm.. the docker-compose.yml looks fine, also the docker ps. You shouldn't need to change anything the vroom config, that's the advantage of network_mode: host. Can you try to:

• remove the network_mode: host
• add the ports: -3000:3000 again
• change the host in the vroom config for OSRM to be osrm instead of 0.0.0.0

What that'll do is set up a private docker network where vroom calls osrm within this private network, that's why you have to set the host to the docker-compose's service name for OSRM. That's really the better way to go anyways, but requires some manual stuff. If that works for you, then I need to investigate at some point why network_mode: host doesn't..

[constantineh]

Finally works like a charm with the above setup!
I was reading in stack overflow that it might be a problem using network_mode: host with macs.
