In terms of Docker, a bridge network uses a software bridge that allows containers connected to the same bridge network to communicate, while providing isolation from containers that are not connected to that bridge network.
The Docker bridge driver automatically installs rules in the host machine so that containers on different bridge networks cannot communicate directly with each other.
Bridge networks apply to containers running on the same Docker daemon host. For communication among containers running on different Docker daemon hosts, you can either manage routing at the OS level, or you can use an overlay network.
When you start Docker, a default bridge network (also called bridge) is created automatically, and newly-started containers connect to it unless otherwise specified. You can also create user-defined custom bridge networks. User-defined bridge networks are superior to the default bridge network.

Didn't you forgot "Preserve user defined networks
" under "Settings -> Docker"? Otherwise the custom Networks will not be persist?
What about assigning or change the subnet?
Hello all wondering if someone can lend a hand. I created a custom network for some of my docker containers.
but every time I switch docker containers to it I get a "docker: Error response from daemon: network Proxy not found."
I have yes'ed "Preserve user defined networks"
This reminds me of Fireship io would love to see more short/precise videos
Is there a way to get ipv6 working as well
Is there a way to define which NIC the custom network will use, if you have multiple NICs? I have one custom bridge already that uses BR0, would like to create a second that uses BR1.
Appreciate the quick tip Sycotix! Off-topic but any chance you could please ID the track in the background of the vid? Keep 'em coming!
what happens if you have prexisting containers? sonarr, radarr, sab, deluge? will it turn to custard if you change the networks?
as always, good shit thumbs up.
I guess I now have to stop asking how to create a custom docker network?
I get the how, what about the why? Why this over host or bridged?
Not arguing against separating it out, but I don't understand why this in particular if that makes sense?
Okay, but how do you have your notifications set up like that in the top right corner?
