Spliting Container Linux Configuration in multiple files

[Beetix]

Hi,

Is it possible to split the Container Linux Configuration in multiple files? Is there an include mechanism?

Thanks

There is a runtime include mechanism, so you can have a single config that references multiple others that get appended. Check out ignition.config.append here https://www.flatcar-linux.org/docs/latest/provisioning/config-transpiler/configuration/. Is that what you're after?

I've just tried it like so:

ignition:
  config:
    append:
      - source: "../services/service.yaml"

I am getting an invalid url scheme error. My understanding is that it doesn't support inclusion of files from the local filesystem, right?

I saw in ct's usage a files-dir option. Is this used for the configuration yaml files?

Thank you for your help

ct's files-dir is applicable to storage.files.contents.local. ignition.config.append needs to be:

the URL of the config. Supported schemes are http, https, s3, tftp, and data

The only way to make this work right now, would be to format the configuration in the source field manually:

printf "data:;base64,%s\n" "$(ct <service.yaml | base64 -w 0)"

This value needs to go into the source field.

I see. Not very convenient 😬

Thanks

This will be possible when we upgrade to ignition v3.
