Unable to start Docker in WSL2 using new Windows Terminal

Question

I have recently installed WSL2 and installed Ubuntu from Microsoft Store.When i run docker using

Sudo service docker start, i get below message

Cannot connect to the Docker daemon. Is the docker daemon running on this host?

I followed steps as per this Answer and did below

    sudo groupadd docker
sudo usermod -aG docker $(whoami)

But still cant start docker..when checking Docker logs, i could see below

CONNECTING" module=grpc Error starting daemon: Error initializing network controller: error obtaining controller instance: failed to create NAT chain DOCKER: iptables failed: iptables -t nat -N DOCKER: iptables v1.6.1: can't initialize iptables table nat': Table does not exist (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded. (exit status 3) `

I have tried a lot of steps based on the error below

can't initialize iptables table nat': Table does not exist (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded. (exit status 3) `

But Starting Terminal as administrator worked.Even though you run

sudo service docker start

The Terminal should be launched as Admin

Launching PowerShell as Administrator solved the problem for me!! So much thanks – FonzTech Oct 21 '20 at 12:14
If anyone is getting "CHAIN_ADD failed (No such file or directory): chain PREROUTING" because you are using Debian, refer to this: https://forums.docker.com/t/failing-to-start-dockerd-failed-to-create-nat-chain-docker/78269/2 – Himbeer Oct 30 '20 at 18:01

There is a great guide here which gives some up to date instructions and some prerequisites on using WSL 2 and the new docker desktop.
