This improves the overall cloud CLI experience workflow. Now whether a stack is local or cloud is inherent to the stack itself. If you interact with a cloud stack, we transparently talk to the cloud; if you interact with a local stack, we just do the right thing, and perform all operations locally. Aside from sometimes seeing a cloud emoji pop-up ☁️, the experience is quite similar. For example, to initialize a new cloud stack, simply: $ pulumi login Logging into Pulumi Cloud: https://pulumi.com/ Enter Pulumi access token: <enter your token> $ pulumi stack init my-cloud-stack Note that you may log into a specific cloud if you'd like. For now, this is just for our own testing purposes, but someday when we support custom clouds (e.g., Enterprise), you can just say: $ pulumi login --cloud-url https://corp.acme.my-ppc.net:9873 The cloud is now the default. If you instead prefer a "fire and forget" style of stack, you can skip the login and pass `--local`: $ pulumi stack init my-faf-stack --local If you are logged in and run `pulumi`, we tell you as much: $ pulumi Usage: pulumi [command] // as before... Currently logged into the Pulumi Cloud ☁️ https://pulumi.com/ And if you list your stacks, we tell you which one is local or not: $ pulumi stack ls NAME LAST UPDATE RESOURCE COUNT CLOUD URL my-cloud-stack 2017-12-01 ... 3 https://pulumi.com/ my-faf-stack n/a 0 n/a And `pulumi stack` by itself prints information like your cloud org, PPC name, and so on, in addition to the usuals. I shall write up more details and make sure to document these changes. This change also fairly significantly refactors the layout of cloud versus local logic, so that the cmd/ package is resonsible for CLI things, and the new pkg/backend/ package is responsible for the backends. The following is the overall resulting package architecture: * The backend.Backend interface can be implemented to substitute a new backend. This has operations to get and list stacks, perform updates, and so on. * The backend.Stack struct is a wrapper around a stack that has or is being manipulated by a Backend. It resembles our existing Stack notions in the engine, but carries additional metadata about its source. Notably, it offers functions that allow operations like updating and deleting on the Backend from which it came. * There is very little else in the pkg/backend/ package. * A new package, pkg/backend/local/, encapsulates all local state management for "fire and forget" scenarios. It simply implements the above logic and contains anything specific to the local experience. * A peer package, pkg/backend/cloud/, encapsulates all logic required for the cloud experience. This includes its subpackage apitype/ which contains JSON schema descriptions required for REST calls against the cloud backend. It also contains handy functions to list which clouds we have authenticated with. * A subpackage here, pkg/backend/state/, is not a provider at all. Instead, it contains all of the state management functions that are currently shared between local and cloud backends. This includes configuration logic -- including encryption -- as well as logic pertaining to which stacks are known to the workspace. This addresses pulumi/pulumi#629 and pulumi/pulumi#494.
