Error: error creating build container: writing blob: storing blob to file "/var/tmp/storage979763649/1": write /var/tmp/storage979763649/1: no space left on device

GitHub to the rescue: -

Hitting "Error committing the finished image" "no space left on device" due to nonoptimized use of disk #3846

and easy to resolve - nuke the Podman machine (VM): -

podman machine rm

The following files will be deleted:


/Users/hayd/.ssh/podman-machine-default

/Users/hayd/.ssh/podman-machine-default.pub

/Users/hayd/.config/containers/podman/machine/qemu/podman-machine-default.ign

/Users/hayd/.config/containers/podman/machine/qemu/podman-machine-default.json



Are you sure you want to continue? [y/N] y

and create a new one: -

podman machine init

and start it: -

podman machine start

and now we're golden: -

docker build -t hello-world:latest -f Dockerfile .
