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