Issue with Docker-isolation

[evilmonkey19]

Hi,

I have an issue that when i try to deploy the lab after destroying it i get this error:

18:56:09 INFO Containerlab started version=0.71.1

I am using ContainerLab in an Ubuntu 24.04 machine. I have the following lab:

name: mikrotik-lab

      endpoint:

If I reboot the machine I can work with it again, but it is not practical at all. Is this a bug or am I doing something incorrectly?

Something is flushing your ip-tables, I think.. When Docker cannot find the stage-2 chain it aborts the network creation. Instead of restarting the machine, you can restart the docker service, this should bring the chain back as well. But check
https://containerlab.dev/manual/network/#external-access

You can also try

name: no-ext-access
mgmt:
  external-access: false 
topology:
# your regular topology definition

I have tried you solution but I still get the same issue. I have tried restarting docker. I add some more debug just in case it helps. I' am using nftables instead of iptables:

I have partly solved the issue. I had to enable nftables in docker as I didn't enable it before.

Hi,

I believe I understand the issue and how to fix it. Docker added support for nftables a few weeks ago. Many people might have installed docker using Docker-CE which is deprecated because AI recommends it (it happened to me as well...). The solution is to uninstall Docker and reinstall it using Docker desktop oficial.

[hellt]

docker-ce is not deprecated, the repo is
the official installation for docker-ce is NOT via docker desktop and is linked from the containerlab site and docker.com - https://docs.docker.com/engine/install/

[evilmonkey19]

oooh okey, you're right that it isn't deprecated. I just found that reading through it and seeing it as archived mislead me to think it is deprecated.
