For me launching dockerd failed since chain of commands with ifconfig returned some extra garbage.
dockerd
ifconfig
I was able to fix it with adding | head -n 1 at the end, so final command would look like:
| head -n 1
sudo dockerd -H `ifconfig eth0 | grep -E "([0-9]{1,3}.){3}[0-9]{1,3}" | grep -v 127.0.0.1 |awk '{ print $2 }' | cut -f2 -d: | head -n 1`
You need to escape the dot (.) in the regexp as such:
"([0-9]{1,3}[.]){3}[0-9]{1,3}"
Then it will work as expected.
