This PR removes three command line parameters from Cloud-enabled Pulumi commands (`update` and `stack init`). Previously we required users to pass in `--organization`, `--repository`, and `--project`. But with the recent "Pulumi repository" changes, we can now get that from the Pulumi workspace. And the project name from the `Pulumi.yaml`.
This PR also fixes a bugs that block the Cloud-enabled CLI path: `update` was getting the stack name via `explicitOrCurrent`, but that fails if the current stack (e.g. the one just initialized in the cloud) doesn't exist on the local disk.
As for better handling of "current stack" and and Cloud-enabled commands, https://github.com/pulumi/pulumi/pull/493 and the PR to enable `stack select`, `stack rm`, and `stack ls` do a better job of handling situations like this.
This PR enables the `pulumi stack init` to work against the Pulumi Cloud. Of note, I using the approach described in https://github.com/pulumi/pulumi-service/issues/240. The command takes an optional `--cloud` parameter, but otherwise will use the "default cloud" for the target organization.
I also went back and revised `pulumi update` to do this as well. (Removing the `--cloud` parameter.)
Note that neither of the commands will not work against `pulumi-service` head, as they require some API refactorings I'm working on right now.
We now encrypt secrets at rest based on a key derived from a user
suplied passphrase.
The system is designed in a way such that we should be able to have a
different decrypter (either using a local key or some remote service
in the Pulumi.com case in the future).
Care is taken to ensure that we do not leak decrypted secrets into the
"info" section of the checkpoint file (since we currently store the
config there).
In addtion, secrets are "pay for play", a passphrase is only needed
when dealing with a value that's encrypted. If secure config values
are not used, `pulumi` will never prompt you for a
passphrase. Otherwise, we only prompt if we know we are going to need
to decrypt the value. For example, `pulumi config <key>` only prompts
if `<key>` is encrypted and `pulumi deploy` and friends only prompt if
you are targeting a stack that has secure configuration assoicated
with it.
Secure values show up as unecrypted config values inside the language
hosts and providers.
Previously we used the word "Environment" as the term for a deployment
target, but since then we've started to use the term Stack. Adopt this
across the CLI.
From a user's point of view, there are a few changes:
1. The `env` verb has been renamed to `stack`
2. The `-e` and `--env` options to commands which operate on an
environment now take `-s` or `--stack` instead.
3. Becase of (2), the commands that used `-s` to display a summary now
only support passing the full option name (`--summary`).
On the local file system, we still store checkpoint data in the `env`
sub-folder under `.pulumi` (so we can reuse existing checkpoint files
that were written to the old folder)
