Hi, @crobisaur
Which docker version do you use?
For the latest docker v28.0.2, you will need to enable the below config:
CONFIG_IP_NF_RAW=m
If downgrading docker is an option for you, docker v27.5.1 should work normally without updating the kernel.
$ sudo apt-get install -y docker-ce=5:27.5* docker-ce-cli=5:27.5* --allow-downgrades
Thanks.
