When I try to create a docker image of my application that needs to be used, I get the below error.
devmapper: Thin Pool has 8783 free data blocks which is less than minimum required 163840 free data blocks. Create more free space in thin pool or use dm.min_free_space option to change behavior
I tried the cleaning up as mentioned in the other forums, but not helped much and getting the same error. When I tried to run with this sudo docker --storage-opt dm.min_free_space=0%, seems like it starts as a daemon, but still it failed with another error “docker-runc not installed on system” and also I dont want to run it as a daemon.
Below are some command outputs
