@billiaz I think this is something that should be implemented on zwavejs side first. @AlCalzone I agree that this would be cool, but should we use npm update zwave-js@config for that or should we use another way?

@robertsLando i do not disagree, till then, having a docker file, able with an argument to update devices is nice feature
By default is disabled, u les you set a value on build argukent deviceUpdate.

I'm still planning to auto-update @zwave-js/config, but until that is implemented, I think we can do it during the build.

The change I propose is not documented well.

More details:

• Following the normal build, without modifying any argument. It will build a container without updating the database
• Adding a --build-arg updateDevices=on with any value instead of on it will trigger the cloning of the repository under the zwavejs argument
• We can override the target repository by also adding the argument --build-arg zwavejs=<git endpoint>. This solves the reason I though of adding this option. I can this way Debug device additions without the need of compiling the zwave-js module.

I find it helpful for people (with or without implemented the auto-update happening through driver, to give the ability on people to participate in these projects.
