Debian 9, I see. I am a bit confused on how to solve this because Im very new to this, so I would appreciate any help.

Everything will work fine when I'll see the message "API listen on 172.18.75.23:2375". The issue is more easily reproduced on my system by just running ping commands inside the latest alpine image: The problem was that even though I had reverted to iptables-legacy in Debian, I still had iptables: "false" in my docker daemon.json.

On the official Data Gateway documentation it says th. This will set the default version to WSL 2, or fail if you are still on the first version.

To do so, we just need first to run a powershell script launching dockerd in WSL2 and once dockerd is listening we can simply use the command docker (maintained by Stefan Scherer). If the /etc/docker directory does not exist yet, create it with sudo mkdir /etc/docker/ so it can contain the config file. I mainly followed these instructions to install Ubuntu 20.04-LTS using WSL2 and prepare everything that dockerd is running inside this instance.
