kube-spawn start fails due to missing image files

[tiagomlalves]

I'm trying to start a kubernetes cluster with kube-spawn but I'm having issues with image retrieval. I'm using latest version.

Steps:
$ sudo kube-spawn create

Copying files for cluster ...
Generating configuration files from templates ...
Cluster default created

$ sudo kube-spawn start -n 5

Could not set limit: Failed to adjust loopback limit: Is a directory
image resize failed: qemu-img not installed: exec: "qemu-img": executable file not found in $PATH
Resize '/var/lib/machines' of 'max'

Failed to retrieve image file. (Wrong URL?)
Exiting.
Failed to start cluster: error running machinectl pull-raw: exit status 1

I have 104Gb disk free in the system, so no disk space issues. Passing different options to --flatcar-channel end up with same error.

Did you install the dependencies? You're missing qemu-img so I'm guessing not.

For Fedora try:

sudo dnf install -y btrfs-progs git go iptables libselinux-utils polkit qemu-img systemd-container

For Ubuntu:

sudo apt-get install -y btrfs-progs git golang iptables policykit-1 qemu-utils selinux-utils systemd-container
