We were not propagating the error from `deployLatest` through
to the CLI error result. Despite out recent efforts to integrate
gometalinter, there were also several additional similar cases of
ignored error results reported by `errcheck`. Not yet clear why
these are not being reported via gometalinter.
Fixes#262.
In the old system, the core runtime/toolset understood that we are targeting
specific cloud providers at a very deep level. In fact, the whole code-generation
phase of the compiler was based on it.
In the new system, this difference is less of a "special" concern, and more of
a general one of mapping MuIL objects to resource providers, and letting *them*
gather up any configuration they need in a more general purpose way.
Therefore, most of this stuff can go. I've merged in a small amount of it to
the mu/x MuPackage, since that has to switch on cloud IaaS and CaaS providers in
order to decide what kind of resources to provision. For example, it has a
mu.x.Cluster stack type that itself provisions a lot of the barebone essential
resources, like a virtual private cloud and its associated networking components.
I suspect *some* knowledge of this will surface again as we implement more
runtime presence (discovery, etc). But for the time being, it's a distraction
getting the core model running. I've retained some of the old AWS code in the
new pkg/resource/providers/aws package, in case I want to reuse some of it when
implementing our first AWS resource providers. (Although we won't be using
CloudFormation, some of the name generation code might be useful.) So, the
ships aren't completely burned to the ground, but they are certainly on 🔥.
This adds a bunch of general scaffolding and the beginning of a `build` command.
The general engineering scaffolding includes:
* Glide for dependency management.
* A Makefile that runs govet and golint during builds.
* Google's Glog library for logging.
* Cobra for command line functionality.
The Mu-specific scaffolding includes some packages:
* mu/pkg/diag: A package for compiler-like diagnostics. It's fairly barebones
at the moment, however we can embellish this over time.
* mu/pkg/errors: A package containing Mu's predefined set of errors.
* mu/pkg/workspace: A package containing workspace-related convenience helpers.
in addition to a main entrypoint that simply wires up and invokes the CLI. From
there, the mu/cmd package takes over, with the Cobra-defined CLI commands.
Finally, the mu/pkg/compiler package actually implements the compiler behavior.
Or, it will. For now, it simply parses a JSON or YAML Mufile into the core
mu/pkg/api types, and prints out the result.
