Autostart docker on wsl2

readme.md

Create line in sudo visudo (at WSL to prevent asking password):

  %sudo   ALL=(ALL) NOPASSWD: /usr/sbin/service docker start

Add in ~/.bashrc

# Start Docker daemon automatically when logging in if not running.
RUNNING=`ps aux | grep dockerd | grep -v grep`
if [ -z "$RUNNING" ]; then
    sudo /usr/sbin/service docker start > /dev/null 2>&1 &
    disown
fi

After restarting the service, it will start automatically.
