When using StackReference, if the stack you reference contains any
secret outputs, we have to mark the entire `outputs` member as a
secret output. This is because we only track secretness on a per
`Output<T>` basis.
For `getSecret` and friends, however, we know the name of the output
you are looking up and we can be smarter about if the returned
`Output<T>` should be treated as a secret or not.
This change augments the provider for StackReference such that it also
returns a list of top level stack output names who's values contain
secrets. In the language SDKs, we use this information, when present,
to decide if we should return an `Output<T>` that is marked as a
secret or not. Since the SDK and CLI are independent components, care
is taken to ensure that when the CLI does not return this information,
we behave as we did before (i.e. if any output is a secret, we treat
every output as a secret).
Fixes#2744
Provides an additional helper function to read outputs from a stack reference in case it is known that the stack output must be present. This is similar to the design for config.get and config.require.
Fixes#2343.
This is something of a quick hack to work around the limitations that
are at the root of #2310. In short, `StackReference` resources do not
change during a update because their inputs have not changed and we do
not refresh resources as part of the update by default. We want
`StackReference` to remain a resource for myriad reasons (not the least
of which is to avoid a breaking change), but it does seem correct for it
to refresh its state during each update. Because there is no actual CRUD
operation associated with a `StackReferece`, we can obtain this behavior
by changing the implementation of its ctor in the various SDKs s.t. its
options bag always contains an appropriate `id`, thus indicating a
`Read`.
Fixes#2310.
These changes add a new resource to the Pulumi SDK,
`pulumi.StackReference`, that represents a reference to another stack.
This resource has an output property, `outputs`, that contains the
complete set of outputs for the referenced stack. The Pulumi account
performing the deployment that creates a `StackReference` must have
access to the referenced stack or the call will fail.
This resource is implemented by a builtin provider managed by the engine.
This provider will be used for any custom resources and invokes inside
the `pulumi:pulumi` module. Currently this provider supports only the
`pulumi:pulumi:StackReference` resource.
Fixes#109.
