Issues with building dockerfile in local mode

Product support

Hey,

I’m currently trying to get local mode working for my development device.

I’m running into issues with the local push command.

  1. I don’t see an easy way to specify which Dockerfile to use. Currently I’m duplicating my actual prod file and writing it to Dockerfile.
  2. I am getting push failures when using the *%%RESIN_ARCH%% and %%RESIN_MACHINE_NAME%% syntax in my dockerfile. Is there a good way to run local mode with these values present?

Thanks for the help!

Hi,
For now, creating a Dockerfile based on your Dockerfile.template is the way to get resin local to work.
You can track progress on our effort making Dockerfile.templates to also work in https://github.com/resin-io/resin-cli/issues/604 .

Back in your issue.
You should replace %%RESIN_MACHINE_NAME%% and %%RESIN_ARCH%% in your Dockerfile with the appropriate values for your device, as found in https://docs.resin.io/deployment/docker-templates/ . For example, for a Raspberry Pi 3 app you should use raspberrypi3 and armv8hf respectively.

Give us a note if you face any issues.

Awesome! That’s worked for us!
