Flash does not set up cloud-init files correctly

[ehudkaldor]

here is the command I am running:
→ ./flash --userdata ./home.yml --bootconf ./no-uart-config.txt --device /dev/sdd ~/Downloads/hypriotos-rpi-v1.9.0.img

it seems like after all is done, my home.yaml makes it to the /HypriotOS partition as /user-data, but it is not applied. at the end of my boot sequence, I see certs generated for the pirate user, and the server is named 'black-pearl', which should have changed.

This is RPI 3b.

Can you provide your home.yml file?
I normally use just the --hostname option and the default yml file and I haven't seen problems.

[MatthiasLohr]

I had the same problem. I found that the first line of the yaml file has to be

#cloud-config

You can also use the cloud-init config validator for checking your config: https://coreos.com/validate/

Thanks @MatthiasLohr
I'll check if the ruby YAML gem is installed on macOS automatically, then I can add

ruby -e "require 'yaml';YAML.load_file('./your-user-data-file'); puts 'YAML is ok'"

to the flash script, at least on macOS.

Config has no errors in terms of hostname, but device still has black-pearl hostname, user and password works correctly
