Hello,
I am new to Docker, and i have try to install Docker and docker compose on my debian server to deploy some container.
On this server i am running a virtual machine with KVM, which use a bridge to my network connection.
When i installed docker compose and docker, the bridge is broken.
Docker create several interface, and broke the existing bridge.
I have no container installed and running yet, but i am not able to use correctly my KVM.
What is the way to go to be able to keep my existing bridge and use some container?
