I have secrets that are used during build-time to libraries, where I need to be authenticated. I wanted to use the CLI v9.6.0 where the help seems to make this possible via
balena deploy -B 'ACCESS_KEY=secret' ....
But I only receive an error that it is not possible because the build is unauthenticated. So it seems to me that the buildArg does not get forwarded. Verbose logging doesn’t give a hint since it does not show any output from stdout.
Am I missing something or does anyone know a workaround? Every hint is appreciated.
Thanks in advance
Concerning the workflow/steps-to-reproduce:
$ balena deploy --nocache -B 'ACCESS_KEY=secret' <appName>
... module1: build: context: module1/ args: - ACCESS_KEY ...
... ARG ACCESS_KEY ... RUN <...> $ACCESS_KEY ...
