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

Is there a command I can run to get the container's IP address right from the host after a new container is created?

Basically, once Docker creates the container, I want to roll my own code deployment and container configuration scripts.

Solution 1:

The --format option of inspect comes to the rescue.

Modern Docker client syntax is:

docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' container_name_or_id

Old Docker client syntax is:

docker inspect --format '{{ .NetworkSettings.IPAddress }}' container_name_or_id

These commands will return the Docker container's IP address.

As mentioned in the comments: if you are on Windows, use double quotes " instead of single quotes ' around the curly braces.

You can use docker inspect <container id>.

For example:

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