I’m on fedora 30 with everything to the latest(docker is 19.03.0-rc2) as of this topic, and when i get to the bootstrapping step, it fails and says that my filesystem is unsupported, so i investigated the source code and found out that overlay2 is indeed supported… so i ran the offending line on my terminal and up to no avail, no regex was matched at all…
offending command(without the -q flag):
docker info 2> /dev/null | egrep ‘^Storage Driver: (aufs|zfs|overlay2)$’
No output from terminal
However, upon removing the empty string match(^) It works perfectly and matches my Storage driver:
docker info 2> /dev/null | egrep ‘Storage Driver: (aufs|zfs|overlay2)$’
Storage Driver: overlay2
Why’s the case? Thanks and i can provide any other info if needed!
