Running docker container has no ipAddress #632
Description
- This is a bug report
- This is a feature request
- I searched existing issues before opening this one
Expected behavior
Connecting a container to a network it's already connect should do nothing.
Actual behavior
It does something weird and removes the IPAddress of the container in that network.
- restarting the container solves the issue.
Steps to reproduce the behavior
sudip@Linux-Mint:~$ docker network create --driver overlay --attachable docker
sudip@Linux-Mint:~$ docker run -d --name docker alpine sleep 5m
sudip@Linux-Mint:~$ docker network connect docker docker
sudip@Linux-Mint:~$ docker container inspect docker | grep IPAddress
"SecondaryIPAddresses": null,
"IPAddress": "",
"IPAddress": "10.0.2.8",
sudip@Linux-Mint:~$ docker network connect docker docker
Error response from daemon: endpoint with name docker already exists in network docker
sudip@Linux-Mint:~$ docker container inspect docker | grep IPAddress
"SecondaryIPAddresses": null,
"IPAddress": "",
"IPAddress": "",
sudip@Linux-Mint:~$ docker restart docker
docker
sudip@Linux-Mint:~$ docker container inspect docker | grep IPAddress
"SecondaryIPAddresses": null,
"IPAddress": "",
"IPAddress": "10.0.2.8",
