I just installed docker and I could run a mongodb image in a container, without sudo. The port exposed is 27017.
I'm now trying to access it from a shell running on the host, but it works only with
sudo mongo --port 27017
I don't want to use sudo. Is it possible?
Is it possible?
yes, but i think you're not taking the right approach.
if you're running mongodb in a docker container, you shouldn't be running the mongo shell from your host. you should be running it from your container.
for example, if your docker container is named mydb, you can do this:
docker exec -it mydb mongo
this will execute the mongo shell in the mydb container and give you "interactive" and "terminal emulation" (the -it params) so you can work as if you had the mongo shell directly on your computer.

I want to connect my MongoDB docker with my program in my host.
I try this:
docker pull mongo
docker run -d --name mongodb -p 21017:21017 mongo
docker exec -it mongodb bash
All start fine but I couldn't connect to my host, I try to change my archive /etc/mongod.conf but with anything result.
I have a python program in my host and I want to use docker MongoDB and connect both.
docker container ls
Thank you very much.
That isnt the mongo port 21017:
Mongo port is 27017 .
You need to use below host & port in your python program which resides on docker host -
DB_HOST = localhost
DB_PORT = 27017
From your Docker host, mongoDB container should be accessible at localhost: 27017
Update 1(as suggested by #Schwarz54) -
Also, you are using wrong mongo port, it should be 27017.
Run your container using below command -
docker run -d --name mongodb -p 27017:27017 mongo
I find the problem, it was that in my python program I don't remember to import mongo.
Yes, that was the problem.
Now I can:
myclient = pymongo.MongoClient("mongodb://192.168.10.170:55059")
And all fine.
Thank you for the help I stay two days checking all the code but I don't remember to see if I import the library...
I have a bitnami mongo image that i start using:
docker run -p 27017:27017 -it --name mongodb <myregistry>.azurecr.io/movo.mongodb
I seed the mongo database using a script from which the output can be seen on the left hand of the image.
The problem:
I can connect the database using the mongo-cli.
However, i can't authenticate using Robo3T or my C# solution, using an identical connectionstring..
This works:
docker exec -it mongodb mongo admin -u movoproto -p "...<MyPwd>..."
But i cannot authenticate in any other way.
The connection does not seem to be the problem...
I've got an identical setup on my laptop where it workes fine...
After some fiddling i figured out what the issue was in the end.
It appears mongodb on windows can start as a local service, which runs a database on 127.0.0.1:27017.
So using Robo3T I was connecting to this local instance instead of my mapped docker mongo instance.
With Robo3T i could connect to this local instance when i unticked 'Perform Authentication'.
In Robo3T you can choose -> Right-click 'Open shell' -> db.hostInfo() -> F5 -> View results in text mode.
This would give info about my desktop computer
Whereas docker exec -it mongodb mongo --eval 'db.hostInfo()' would display information regarding my docker image.
My solution was to disable the mongo service on my desktop pc that runs the local database.
Doing this would let docker run -p 27017:27017 -it --name mongodb <myregistry>.azurecr.io/movo.mongodb bind to my docker container at 127.0.0.1:27017
Is it possible to connect to a process running in a Docker container but exactly via container's loopback interface ?
Basically I am looking for this option:
docker run ... -p 12345:127.0.0.1:12345 ...
This is rejected by Docker.
The use case is for example to setup Mongo admin user via Localhost Exception
You have the port mapping slightly wrong. Try it like this:
$ docker run -itd -p 27117:27017 mongo
so 27117 is the port you can connect to outwith the docker container, and 27017 is the port mongod is running on within docker
So when I connect the mongo shell I can connect to the mongod within docker like:
$ mongo --port 27117
Try like this :
Step 1 :
pulling mongo image from docker.
docker pull mongo
Step 2 :
Create new directory for storing mongodb data in you shared location like /home/user/databases/mongo
Step 3:
Run mongodb from docker image using below command
if you want change the mongodb port like 12345 set it in the command. 27017 is globally declared in docker you cannot change it but i want locally change the mongodb port like 12345
docker run -d -p 12345:27017 -v /home/user/databases/mongo:/data/db --name mongodb mongo
I just downloaded Docker and created the MongoDB container on it.
I have successfully created the container and it is working on the port 168.192.99.100:32728 on my local machine. I'm confused how should I run mongo on my machine?
For example if we create the SQL container we can connect to the port using MySQL Workbench. How do i do something similar for Mongo?
You have at least two options:
Running the mongo-client on your host-system (requires install of mongo-client):
mongo --host 168.192.99.100 --port 32728
see https://docs.mongodb.com/manual/reference/program/mongo/#bin.mongo
or maybe the simpler option of attaching to the docker-container with the running mongodb-server which already should have a mongo-client installed:
docker exec -it "name of container" mongo
https://docs.docker.com/engine/reference/commandline/exec/
I am using the official mongodb docker container.
I want to connect to the mongodb container from my host machine on port 27017.
I ran the container with these ports exposed
-p 27017:27017
I am not able to connect (connection refused) and I believe its because the mongo conf file is not configured to allow remote connections. How can I configure it to allow? The official container does not have vi/nano installed to modify the image.
I am able to connect to mongodb from another container by creating a link - however this is not my wish

My answer to another question. How to enable authentication on MongoDB through Docker?
Here's what I did for the same problem, and it worked.
Run the mongo docker instance on your server
docker run -d -p 27017:27017 -v ~/dataMongo:/data/db mongo
Open bash on the running docker instance.
docker ps

Enter the mongo shell by typing mongo.

For this example, I will set up a user named ian and give that user read & write access to the cool_db database.
> use cool_db
> db.createUser({
user: 'ian',
pwd: 'secretPassword',
roles: [{ role: 'readWrite', db:'cool_db'}]
})
Reference: https://ianlondon.github.io/blog/mongodb-auth/ (First point only)
Exit from mongod shell and bash.
Now run the mongo docker with auth enabled.
docker run -d -p 27017:27017 -v ~/dataMongo:/data/db mongo mongod --auth

I was able to connect to the instance running on a Google Cloud server from my local windows laptop using the below command.
mongo <ip>:27017/cool_db -u ian -p secretPassword
