Any chance to use this task without publishing the modules to Azure CR? The only thing I want is that the deployment manifest is transfered it to the IoT-Hub 😉 - no further validations/actions are needed.

Thanks in advance - and please let me know if I was unclear or could contribute further information.

@alaendle Thank you for your feedback, the docs have been updated with the environment variable SKIP_MODULE_IMAGE_VALIDATION option. Please let us know if you run into any other issues

@20shivangi Do you think you can close this issue? Thanks!

Hi @alaendle,

you can set the environment variable named SKIP_MODULE_IMAGE_VALIDATION to true to skip the image validation. So far I could not find this hint in the documentation. Here is the code line that checks if a check should be performed.
