No space issue! while creating a cluster. How to clear the space?

[SundeepPaluru]

unable to build the cluster due to space issues. how can we clear or fix this from our end?

Currently sizes are shown as below? I'm using docker account to login

df -h gives this:
Filesystem Size Used Avail Use% Mounted on
overlay 10G 141M 9.9G 2% /
/dev/sdb 64G 64G 3.9M 100% /etc/hosts
