Description
I experienced an issue when I tried to run a k8s master on my mac.
I use the following versions:
- MacOS-X High Sierra 10.13
- linuxkit version 0.0 / commit: 41a4c2df108bc739897e6a6f9234e6c794ab380f
- moby version 0.0 / commit: 6ba3288963c52b0831e72f99851b565baf6498e4
Steps to reproduce the issue:
- Clone the repo
- cd to the repo root
- run: make all
- run: ./boot.sh
Describe the results you received:
I get the following exception:
linuxkit-kubernetes git/master 12s
❯ ./boot.sh
+ '[' -n '' ']'
+ mkdir -p kube-master-state
+ touch kube-master-state/metadata.json
+ '[' -n '' ']'
+ linuxkit run -networking default -cpus 2 -mem 1024 -state kube-master-state -disk size=4G -data kube-master-state/metadata.json --uefi kube-master-efi.iso
FATA[0000] Cannot write user data ISO: input buffer must be at least 1 byte in size
Describe the results you expected:
The k8s master should start.
Additional information you deem important (e.g. issue happens only occasionally):
I was able to resolve the issue by just adding an empty json object to the metadata.json file. I've committed the 'fix' to my fork: https://github.com/synax/linuxkit-kubernetes/commit/56ad664bb721cb918ee6047b5b09f879f1b44ab1
