Instead of needing you to first select the current stack to use any of
these commands, allow passing `-s <stack-name>` or `--stack
<stack-name>` to say what stack you want to operate on.
These commands still require a `Pulumi.yaml` file to be present, which
is not ideal, but would require a larger refactoring to fix. That
refactoring will happen as part of #1556.
Fixes#1370
This change supports displaying manifest information for a stack and
changes the way we handle Snapshots in our backend.
Previously, every call to GetStack would synthesize a Snapshot by
taking the set of resources returned from the
`/api/stacks/<owner>/<name>` endpoint, combined with an empty
manfiest (since the service was not returning the manifest).
This wasn't great for two reasons:
1. We didn't have manifest information, so we couldn't display any of
its information (most important the last updated time).
2. This strategy required that the service return all the resources
for a stack anytime GetStack was called. While the CLI did not
often need this detailed information the fact that we forced the
Service to produce it (which in the case of stack managed PPC would
require the service to talk to yet another service) creates a bunch
of work that we end up ignoring.
I've refactored the code such that `backend.Stack`'s `Snapshot()` method
now lazily requests the information from the service such that we can
construct a `Snapshot()` on demand and only pay the cost when we
actually need it.
I think making more of this stuff lazy is the long term direction we
want to follow.
Unfortunately, right now, it means in cases where we do need this data
we end up fetching it twice. The service does it once when we call
GetStack and then we do it again when we actually need to get at the
Snapshot. However, once we land this change, we can update the
service to no longer return resources on the apistack.Stack type. The
CLI no longer needs this property. We'll likely want to continue in a
direction where `apistack.Stack` can be created quickly by the
service (without expensive database queries or fetching remote
resources) and just add additional endpoints that let us get at the
specific information we want in the specific cases when we want it
instead of forcing us to return a bunch of data that we often ignore.
Fixespulumi/pulumi-service#371
1. Output different-colored edges for parent-child resource
relationships
2. Allow the changing of edge colors via command-line parameters
3. Allow the skipping of the parent-child graph or the
dependency graph when calculating all edges
This modifies the Graph interface slightly to allow an edge to specify
what color should be used when drawing it.
This commit does two things:
1. All dependencies of a resource, both implicit and explicit, are
communicated directly to the engine when registering a resource. The
engine keeps track of these dependencies and ultimately serializes
them out to the checkpoint file upon successful deployment.
2. Once a successful deployment is done, the new `pulumi stack
graph` command reads the checkpoint file and outputs the dependency
information within in the DOT format.
Keeping track of dependency information within the checkpoint file is
desirable for a number of reasons, most notably delete-before-create,
where we want to delete resources before we have created their
replacement when performing an update.
