[che-dev] "Hello World" issue for Che 7

[Dave Neary <dneary@xxxxxxxxxx>]

Hi all,

I thought I would create a devfile for the simplest project I could
think of for Che 7, and document what was involved.

You can follow along here:
https://github.com/dneary/hello-world/

This is a single C file and Makefile to compile it to a binary.
Prerequisites are GCC and make, and I want to have a build target that
runs make, and a run target that runs hello in the terminal.

The issues I'm having are how to make a bare bones devfile. I get the
following errors (formated for ease of reading - 2 questions to follow):

> Error occurred during creation a workspace from devfile located at `https://raw.githubusercontent.com/dneary/hello-world/master/devfile.yaml`.
> 
> Cause: Devfile schema validation failed.
> Errors: [
> 
> /devfile/components/0 object instance has properties which are not allowed by the schema: ["mountsources"],
> instance failed to match exactly one schema (matched 0 out of 3),
> /devfile/components/0 object instance has properties which are not allowed by the schema: ["args","command","env","image","mountsources"],
> /devfile/components/0 object has missing required properties (["id"]),
> /devfile/components/0 object instance has properties which are not allowed by the schema: ["args","command","env","image","memoryLimit","mountsources"],
> instance failed to match at least one required schema among 2,
> /devfile/components/0 object has missing required properties (["reference"]),
> /devfile/components/0 object has missing required properties (["referenceContent"]),
> /devfile/components/0 object instance has properties which are not allowed by the schema: ["mountsources"]
> ]


My questions:

* Is there a devfile schema validator I can run locally which will save
me doing testing by trying to run this through che.openshift.io (my
current testing method)?
* What is the strict minimal devfile that I would need to have to be
able to compile and run my project?

Thanks,
Dave.
