curl -fsSL https://get.docker.com -o /tmp/get-docker.sh
sed -i -e 's/sleep 20/sleep 1/' /tmp/get-docker.sh
sh /tmp/get-docker.sh

# Enable iptables compatibility
echo 1 | update-alternatives --config iptables

# exit from being root
exit

# Add your user to the Docker group
sudo usermod -aG docker $USER

# Enable docker on startup
fgrep -q wsl.exe ~/.profile || {
cat <<'eof' >> ~/.profile

# check if docker is running
if grep -q "microsoft" /proc/version > /dev/null 2>&1; then
  if service docker status 2>&1 | grep -q "is not running"; then
    wsl.exe --distribution "${WSL_DISTRO_NAME}" --user root \
       --exec /usr/sbin/service docker start > /dev/null 2>&1
