无法使用pymongo连接到mongdb docker内部

Question

so i've made a docker container with mongodb on a distant computer 192.168.0.17 i run the container with this command :

docker run -t -i -p 27019:27019 mongodb /bin/bash

inside the container i run it as a user wok with theses option :

mongod --bind_ip 0.0.0.0 --noauth

here is the output (i've created and given the right to wok to /data/db/) :

wok@91cf429cfc28:~$ mongod --bind_ip 0.0.0.0 --noauth
warning: bind_ip of 0.0.0.0 is unnecessary; listens on all ips by default

so here is my little script with pymongo on the 192.168.0.16 computer :

from pymongo import MongoClient
from datetime import datetime
client = MongoClient("mongodb://192.168.0.17:27019")
db = client.test
result = db.restaurants.insert_one(
    {
        "address": {
            "street": "2 Avenue",
            "zipcode": "10075",
            "building": "1480",
            "coord": [-73.9557413, 40.7720266]
        },
        "borough": "Manhattan",
        "cuisine": "Italian",
        "grades": [
            {
                "date": datetime.strptime("2014-10-01", "%Y-%m-%d"),
                "grade": "A",
                "score": 11
            },
            {
                "date": datetime.strptime("2014-01-16", "%Y-%m-%d"),
                "grade": "B",
                "score": 17
            }
        ],
        "name": "Vella",
        "restaurant_id": "41704620"
    }
)

print(result)

so i have a connection refused error :

Traceback (most recent call last):
  File "/home/bussiere/WorkspaceSafe/testmongo.py", line 28, in <module>
    "restaurant_id": "41704620"

So if anyone have any ideas ... regards

Answer 1

I think your mongo daemon is listening on port 27017, and you're publishing 27019 from the container.

Try: docker run -t -i -p 27019:27017 mongodb /bin/bash
