How to get a Docker container's IP address from the host

Question

How can one get a container's IP address from the host ?

What I am trying to do is to deploy my own code and run configuration scripts for container.

Answer 1

There is a simple command to get an IP of a container

 docker inspect < name_of_container >

If you want to use it in configuration scripts you can write the command like this 

ABC=$(docker run -d -p 4321 base nc -lk 4321);

docker inspect $ABC

There is a slight issue with though, when you run the inspect command - You will get a lot more things than just the IP address of the container.

To get just the IP address you can use grep :

docker inspect < name_of_container > | grep "IPAddress" 

This will give you the IP address of the container only.
