How to Get A Docker Container IP Address

1. Find out your Docker Network

$ docker network ls

NETWORK ID          NAME                DRIVER              SCOPE
b7d8006635be        bridge              bridge              local
4bf0250a2ba1        docker_database     bridge              local
cfb3f7919f74        docker_wwwserver    bridge              local
7b28e5a560ae        host                host                local
27566c00a0e5        none                null                local

2. Use Docker Inspect

$ docker network inspect -f '{{json .Containers}}' cfb3f7919f74 | jq '.[] | .Name + ":" + .IPv4Address'
