I pulled the official mongo image from the Docker website and started a mongo container named dataiomongo.
I now want to connect to the mongodb inside the container using pymongo.
This is the python script I wrote:
from pprint import pprint
from pymongo import MongoClient
client = MongoClient('localhost', port=27017)
db = client.admin
server = db.command("serverStatus")
pprint(server)
The error that came is:
Traceback (most recent call last):
File "D:/dataio/test_mongo.py", line 8, in <module>
server = db.command("serverStatus")
File "D:\dataio\venv\lib\site-packages\pymongo\database.py", line 655, in command

How do I go about connecting to the mongodb inside the docker container?
First you need to run mongo
$ docker run --rm --name my-mongo -it -p 27017:27017 mongo:latest
$ docker run --name my-mongo -d mongo:latest
$ docker run -it --link my-mongo:mongo --rm mongo:latest sh -c 'exec mongo "$MONGO_PORT_27017_TCP_ADDR:$MONGO_PORT_27017_TCP_PORT/test"'
Insert the data into the db
client = MongoClient()
client.server_info()
db = client.yourdbname
I think you miss -p 27017:27017 flag.
docker run -p 27017:27017 --name mymongo -d mongo .
Make sure you bind the 27017 container port to host port via -p 27017:27017 flag.
