Minikube: Minikube fails to start if multiple docker networks' names contain "bridge"

[kadern0]

Steps to reproduce the issue:

1. Run

 ./out/minikube start
😄  minikube v1.10.1 on Ubuntu 20.04
✨  Using the docker driver based on user configuration
👍  Starting control plane node minikube in cluster minikube
🔥  Creating docker container (CPUs=2, Memory=3900MB) ...
🐳  Preparing Kubernetes v1.18.2 on Docker 19.03.2 ...

😿  minikube is exiting due to an error. If the above message is not useful, open an issue:
👉  https://github.com/kubernetes/minikube/issues/new/choose

I've been looking at the error and then at the code and I've found the cause. These are the docker networks on my system:

docker network ls
NETWORK ID          NAME                                       DRIVER              SCOPE
ba7e0589cc69        bridge                                     bridge              local
71a6519a81a0        docker_gwbridge                            bridge              local

So the problem resides within this function: https://github.com/kubernetes/minikube/blob/ad437c2c9ca930629ab4c7c077a27d94b73ccf2e/pkg/drivers/kic/oci/network.go#L63

If you filter the networks the same way this function does, both networks are returned:

docker network ls --filter name=bridge --format "{{.ID}}"
ba7e0589cc69
71a6519a81a0

This makes this assignent contain "ba7e0589cc69\n71a6519a81a0". as shown within the error output before:

bridgeID := strings.TrimSpace(rr.Stdout.String())

[afbjorklund]

This is a duplicate of #8131, even if it is not the swarm bridge but a user-created bridge.

Should be fixed by PR #8034

[kadern0]

Thanks @afbjorklund, it is the same issue.

[medyagh]

@kadern0
cool I will close this in favor of https://github.com/kubernetes/minikube/issues/8274

[markymo5115]

I made sure docker swarm was deactivated with: docker swarm leave --force
then did: docker network prune (this removes the docker swarm network since its not being used although beware it will remove all other unused networks too)
After this minikube ran OK

[medyagh]

@markymo5115 I wonder if you have still this issue with latest version ?

[StefanS111]

I also just installed minikube to encounter this problem. It happened as my installed docker instance was still in swarm mode. The forced leave of the swarm and the pruning does the job though.

[amansarpal]

simple solution to problem is.

1. docker leave swarm
2. docker network prune
