[BUG] After Update Container Restarts with Wrong Network (macvlan)

[djw1191]

Description

I run dockhand using a docker macvlan network and a manually assigned IP address. After updating via the UI, the UI never comes back. Changing locally, docker shows the container as up. Running a docker inspect, shows that the IP address of the container has been changed. In this case, the container has changed its IP to 10.1.22.2.

How I run: docker run -d --name dockhand --restart unless-stopped --net=mgmt --ip=10.1.22.176 -v /var/run/docker.sock:/var/run/docker.sock -v /opt/dockhand:/app/data

After removing and restarting the container, this is the correct network information. As retrieved by docker inspect.

}

Steps to reproduce

1. Create a macvlan docker network
2. Start dockhand assigning that network and a static IP (docker run -d --name dockhand --restart unless-stopped --net=mgmt --ip=10.1.22.176 -v /var/run/docker.sock:/var/run/docker.sock -v /opt/dockhand:/app/data fnsys/dockhand:latest)
3. Update dockhand from within the dockhand UI
4. Observe the UI not returning
5. Run a docker inspect dockhand
6. Observe that dockhand has restarted with a different IP
