Once an instance is started with itzo-launcher on it, itzo-launcher will check user-data, download the version of itzo requested via the usual itzo user-data files, and start itzo.

Passing flags to itzo from KIP

All flags specified in provider.yaml section:

cells:
  cellConfig:
    itzoFlag-use-podman: true

in format itzoFlag<actual flag>: flag value will be passed to itzo command. In example, if you specify:

cells:
  cellConfig:
    itzoFlag-use-podman: true
    itzoFlag-custom-port: 1234

launcher will run itzo -use-podman true -custom-port 1234
