I have this command to start MongoDB in a container:
docker run -p 27017:27017 --name cdt-mongo mongo
this is from these docs:
https://hub.docker.com/_/mongo/
I actually think the
-p 27017:27017
is superfluous. anyway.
Locally, I run the container in one terminal, and then in another terminal I issue the mongo command, and I get:
$ mongo
MongoDB shell version v3.4.2
connecting to: mongodb://127.0.0.1:27017
2017-05-02T11:27:22.864-0700 W NETWORK [thread1] Failed to connect to 127.0.0.1:27017, in(checking socket for error after poll), reason: Connection refused

anybody know why I cannot connect to mongodb running in the container?
because I am on MacOS, I should not connect to
localhost:27017
but instead use the host/ip address of the docker-machine VM
HOST=$(docker-machine ip)
and then connect to it like so:
mongo --host $HOST

Any help?
Ive installed Docker locally (mac) and tried to run a docker container using the following command.
docker run -it -p 27017:27017 mongoImageId
But when I tried to login in to the container via the mongo terminal client, Im getting the following error.
mongo --port 27017 -u "userName" -p "password" --authenticationDatabase "sampleDBName"
MongoDB shell version v3.6.5

But if I try to build the same image in an aws ec2 instance, it connects without a hazel. Does any one else also encountered the same issue and was able to find the root cause ?

I'd like to connect to my AWS instance and connect to my MongoDB database over localhost. The SSH tunnel seems to work, but when I try to connect with mongo I get a connection failed error.
SSH tunnel command:
ssh -i <path to key> -N -L 27017:++++++++++.us-west-2.compute.amazonaws.com:27017 ++++++#++++++++++.us-west-2.compute.amazonaws.com
Mongo client:
mongo -u +++++++ -p ++++++++++ mongodb://localhost:27017/+++++
MongoDB shell version v3.4.7
connecting to: mongodb://localhost:27017/++++++
2018-01-22T15:32:07.125+0100 E QUERY [thread1] Error: network error while attempting to run command 'isMaster' on host 'localhost:27017' :
connect#src/mongo/shell/mongo.js:237:13
#(connect):1:6
exception: connect failed
On the tunnel side I then get:
channel 2: open failed: connect failed: Connection refused
I have tried the mongo command directly on the server then there it works fine.
On my Robo T3 client there is an option to connect over SSH and there the connection works just fine.
Any suggestions are greatly appreciated.
EDIT
When I start the mongo client, no new lines are added to mongdb log file. This indicates that the tunnel is not doing it's job...
According to this documentation, this error happens when you try to connect to a MongoDB server without ssl.
The solution then would be to connect using SSL, which can be done by adding --ssl to your connection query (so that it looks like this: mongo --ssl -u +++++++ -p ++++++++++ mongodb://localhost:27017/+++++).
Let me know if this works for you!
I have installed Mongo docker image and run it using those commands (mac boot2docker is installed)
docker pull mongo
and
docker run --name some-mongo -d mongo
but now I want to connect to it via mongo client running:
mongo --port 27017 --host 127.0.0.1
but I get this error message:
MongoDB shell version: 3.0.4
connecting to: 127.0.0.1:27017/test
2015-07-27T14:22:24.088+0300 W NETWORK Failed to connect to 127.0.0.1:27017, reason: errno:61 Connection refused

It is clear to me that Docker fails to expose the ports since telnet to 27017 on the localhost fails as well.
What the hack am I doing wrong?
You have 2 problems :
Like h3nrik said you should connect to the boot2docker VMs address. If you don't know it use the following command :
boot2docker ip
And your port isn't open in the first place.
Your Docker run command should look like this :
docker run -p 27017:27017 --name some-mongo -d mongo
Instead of 127.0.0.1 you should use the boot2docker VMs IP address. Usually 192.168.59.103. You can verify to which IP you should connect executing boot2docker ip.
Update: I discovered that you do not export any ports by your containers run statement:
docker run --name some-mongo -d mongo
Without any ports exposed you cannot connect, of course. Try to re-connect after running (depending on your requirements you can add more ports according to the mongodb documentation):
docker run --name some-mongo -d -p 27017:27017 mongo
