Can't Connect to MongoDB on new Azure VM

I created a new "Container App" in Azure Portal for MongoDB. This used the official MongoDB container from Docker Hub and created an Ubuntu 15.04 box. I have never worked with Docker before.

I am able to SSH into the VM and connect to mongo on the VM. From the ssh session, if I type:

docker ps

I get the following output:

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                      NAMES 
a9af4c2e2b95        mongo               "/entrypoint.sh mongo"   34 minutes ago      Up 24 minutes       0.0.0.0:27017->27017/tcp   compose_mongo_1

However, when I try to connect to Mongo from my local box, I get a connection error that says "Failed to connect to ... after 5000 milliseconds, giving up."

At first I thought it was because the port wasn't opened, but I went to the "Network Security Groups" in Azure portal and allowed port inbound TCP traffic on port 27017.

I am still unable to connect. If anyone could help me, I would appreciate it.

Thanks!

Ok, A couple of things to keep in mind (and I just tested this end to end, So I am sure it works).

  1. Make sure UFW (Ubuntu Firewall also called Uncomplicated Firewall) denies all forwarded traffic by default, so you need to set it to ACCEPT

    sudo nano /etc/default/ufw

Replace 

DEFAULT_FORWARD_POLICY="DROP"

With

DEFAULT_FORWARD_POLICY="ACCEPT"

and reload the UFW

sudo ufw reload

  1. this is how I run my docker Image

    docker run -p 27017:27017 imageid &

  2. Add the endpoint for port 27017 - from your azure portal for this VM (Which you have already done)

this is it, I think you should be all set now...
