How to connect to mongodb as docker image from another container application

First I pulled the mongoDb image

sudo docker pull mongo
 

And run the docker mongodb container:

sudo docker run --name database -d -p 27017:27017 mongo --noauth --bind_ip=0.0.0.0
 

I see that my Docker container works:

300b779a63a9 mongo "docker-entrypoint..." 30 minutes ago Up 30 minutes
 

Now I’m trying to connect to it via my docker app

sudo docker run -v ~/Desktop/Template/universal_skillskill -it --link 300b779a63a9:300b779a63a9 alexa
 

And…I received a message that the connection was refused:(

Uncaught exception: MongoError: failed to connect to server [0.0.0:27017] on first connect [MongoError: connect ECONNREFUSED 0.0.0.0:27017]
 MongoError: failed to connect to server [0.0.0:27017] on first connect [MongoError: connect ECONNREFUSED 0.0.0.0:27017]
 

I checked and my application works on the locally installed mongodb, but it cannot communicate with the docker mongoDb container: (What am I doing wrong? Can someone please help me 🙂

1>yamenk..:

You need to connect to, 300b779a63a9:27017 as this is the link name you specified for mongodb.

Like this in my container webapp mongoose.connect('mongodb://:300b779a63a9:27017');
