We were previously calling configure on each package once per time it was mentioned in the config. We only need to call it once ever as we pass the full bag of relevent config through on that one call.
It's legal and possible for undefined properties to show up in
objects, since that's an idiomatic JavaScript way of initializing
missing properties. Instead of failing for these during deployment,
we should simply skip marshaling them to Terraform and let it do
its thing as usual. This came up during our customer workload.
Previously, we stored configuration information in the Pulumi.yaml
file. This was a change from the old model where configuration was
stored in a special section of the checkpoint file.
While doing things this way has some upsides with being able to flow
configuration changes with your source code (e.g. fixed values for a
production stack that version with the code) it caused some friction
for the local development scinerio. In this case, setting
configuration values would pend changes to Pulumi.yaml and if you
didn't want to publish these changes, you'd have to remember to remove
them before commiting. It also was problematic for our examples, where
it was not clear if we wanted to actually include values like
`aws:config:region` in our samples. Finally, we found that for our
own pulumi service, we'd have values that would differ across each
individual dev stack, and publishing these values to a global
Pulumi.yaml file would just be adding noise to things.
We now adopt a hybrid model, where by default configuration is stored
locally, in the workspace's settings per project. A new flag `--save`
tests commands to actual operate on the configuration information
stored in Pulumi.yaml.
With the following change, we have have four "slots" configuration
values can end up in:
1. In the Pulumi.yaml file, applies to all stacks
2. In the Pulumi.yaml file, applied to a specific stack
3. In the local workspace.json file, applied to all stacks
4. In the local workspace.json file, applied to a specific stack
When computing the configuration information for a stack, we apply
configuration in the above order, overriding values as we go
along.
We also invert the default behavior of the `pulumi config` commands so
they operate on a specific stack (i.e. how they did before
e3610989). If you want to apply configuration to all stacks, `--all`
can be passed to any configuration command.
Add `Name` (Pulumi project name) and `Runtime` (Pulumi runtime, e.g. "nodejs") properties to `UpdateProgramRequest`; as they are now required.
The long story is that as part of the PPC enabling destroy operations, data that was previously obtained from `Pulumi.yaml` is now required as part of the update request. This PR simply provides that data from the CLI.
This is the final step of a line of breaking changes.

On windows, we have to indirect through a batch file to launch plugins,
which means when we go to close a plugin, we only kill cmd.exe that is
running the batch file and not the underlying node process. This
prevents `pulumi` from exiting cleanly. So on Windows, we also kill any
direct children of the plugin process
Fixes#504
This PR adds integration tests for exercising `pulumi init` and the `pulumi stack *` commands. The only functional change is merging in https://github.com/pulumi/pulumi/pull/492 , which I found while writing the tests and (of course 😁 ) wrote a regression for.
To do this I introduce a new test driver called `PulumiProgram`. This is different from the one found in the `testing/integration`package in that it doesn't try to prescribe a workflow. It really just deals in executing commands, and confirming strings are in the output.
While it doesn't hurt to have more tests for `pulumi`, my motivation here was so that I could reuse these to ensure I keep the same behavior for my pending PR that implements Cloud-enabled variants of some of these commands.
- When looking for a `.pulumi` folder to reuse, only consider ones
that have a `settings.json` in them.
- Make the error message when there is no repository a little more
informative by telling someone to run `pulumi init`
Calls to `NewProjectWorkspace` will panic if there is no Pulumi.yaml found in the folder hierarchy. Simple repo:
```
git init
pulumi init
pulumi stack init x
```
`DetectPackage` will search until it gets to the `.pulumi` directory or finds a `Pulumi.yaml` file. In the case of the former, we pass "" to `LoadPackage` which then asserts because the file doesn't exist.
We now detect this condition and surface an error to the user. The error text is patterned after running a git command when there is no .git folder found:
fatal: Not a git repository (or any of the parent directories): .git
This adds a minimal runtime verification test to our basic
test suite, to at least exercise the portions of the integration
test library that load up and parse checkpoint files.
Now, instead of having a .pulumi folder next to each project, we have
a single .pulumi folder in the root of the repository. This is created
by running `pulumi init`.
When run in a git repository, `pulumi init` will place the .pulumi
file next to the .git folder, so it can be shared across all projects
in a repository. When not in a git repository, it will be created in
the current working directory.
We also start tracking information about the repository itself, in a
new `repo.json` file stored in the root of the .pulumi folder. The
information we track are "owner" and "name" which map to information
we use on pulumi.com.
When run in a git repository with a remote named origin pointing to a
GitHub project, we compute the owner and name by deconstructing
information from the remote's URL. Otherwise, we just use the current
user's username and the name of the current working directory as the
owner and name, respectively.
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.
I noticed in our Docker builds, we often end up seeing %(MISSING)!
style messages, which were an indication we were trying to format
them. The reason was the presence of %c's in the stream, and the
fact that we passed said messages to Fprintf. We were careful in
all other layers to use the message on the "right hand side" of
any *f calls, but in this instance, we used Fprintf and passed the
message on the "left hand side", triggering formatting. It turns
out we've already formatted everything by the time we get here,
so there's no need -- we can just use Fprint instead.
Adds `pulumi update` so you can deploy to the Pulumi Console (via PPC on the backend).
As per an earlier discussion (now lost because I rebased/squashed the commits), we want to be more deliberate about how to bifurcate "local" and "cloud" versions of every Pulumi command.
We can block this PR until we do the refactoring to have `pulumi` commands go through a generic "PulumiCloud" interface. But it would be nice to commit this so I can do more refining of the `pulumi` -> Console -> PPC workflow.
Another known area that will need to be revisited is how we render the PPC events on the CLI. Update events from the PPC are generated in a different format than the `engine.Event`, and we'll probably want to change the PPC to emit messages in the same format. (e.g. how we handle coloring, etc.)
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.
Trapping these signals hijacks the usual termination behavior for any
program that happens to link in the engine and perform an operation
that starts a gRPC server. These servers already provide a cancellation
mechanism via a `cancel` channel parameter; if the using program wants
to gracefully terminate these servers on some signal, it is responsible
for providing that behavior.
This also fixes a leak in which the goroutine responsible for waiting on
a server's signals and cancellation channel would never exit.
When `PULUMI_RETAIN_CHECKPOINTS` is set in the environment, also write
the checkpoint file to <stack-name>.<ext>.<timestamp>.
This ensures we have historical information about every snapshot, which
would aid in debugging issues like #451. We set this to true for our
integration tests.
Fixes#453
This change fixes a couple bugs with assets:
* We weren't recursing into subdirectories in the new "path as
archive" feature, which meant we missed most of the files.
* We need to make paths relative to the root of the archive
directory itself, otherwise paths end up redundantly including
the asset's root folder path.
* We need to clean the file paths before adding them to the
archive asset map, otherwise they are inconsistent between the
path, tar, tgz, and zip cases.
* Ignore directories when traversing zips, since they aren't
included in the other formats.
* Tolerate io.EOF errors when reading the ZIP contents into blobs.
* Add test cases for the four different archive kinds.
This fixespulumi/pulumi-aws#50.
The prior code was a little too aggressive in rejected undefined
properties, because it assumed any occurrence indicated a resource
that was unavailable due to planning. This is a by-produt of our
relatively recent decision to flow undefineds freely during planning.
The problem is, it's entirely legitimate to have undefined values
deep down in JavaScript structures, entirely unrelated to resources
whose property values are unknown due to planning.
This change flows undefined more freely. There really are no
negative consequences of doing so, and avoids hitting some overly
aggressive assertion failures in some important scenarios. Ideally
we would have a way to know statically whether something is a resource
property, and tighten up the assertions just to catch possible bugs
in the system, but because this is JavaScript, and all the assertions
are happening at runtime, we simply lack the necessary metadata to do so.
Now that config is stored in Pulumi.yaml, we need to mimic the behavior
around .pulumi/ while edits are applied. This will ensure that config
values carry forward from the original program settings.
This fixespulumi/pulumi-aws#48.
The event diagnostic goroutines could error out sometimes during
early program exits, due to a race between the goroutine writing to
the channel and the early exiting goroutine which closed the channel.
This change stops closing the channels entirely on the abrupt exit
paths, since it's not necessary and we want to exit immediately.
This improves a few things about assets:
* Compute and store hashes as input properties, so that changes on
disk are recognized and trigger updates (pulumi/pulumi#153).
* Issue explicit and prompt diagnostics when an asset is missing or
of an unexpected kind, rather than failing late (pulumi/pulumi#156).
* Permit raw directories to be passed as archives, in addition to
archive formats like tar, zip, etc. (pulumi/pulumi#240).
* Permit not only assets as elements of an archive's member list, but
also other archives themselves (pulumi/pulumi#280).
The existing `SnapshotProvider` interface does not sufficiently lend
itself to reliable persistence of snapshot data. For example, consider
the following:
- The deployment engine creates a resource
- The snapshot provider fails to save the updated snapshot
In this scenario, we have no mechanism by which we can discover that the
existing snapshot (if any) does not reflect the actual state of the
resources managed by the stack, and future updates may operate
incorrectly. To address this, these changes split snapshotting into two
phases: the `Begin` phase and the `End` phase. A provider that needs to
be robust against the scenario described above (or any other scenario
that allows for a mutation to the state of the stack that is not
persisted) can use the `Begin` phase to persist the fact that there are
outstanding mutations to the stack. It would then use the `End` phase to
persist the updated snapshot and indicate that the mutation is no longer
outstanding. These steps are somewhat analogous to the prepare and
commit phases of two-phase commit.
If --logtostderr is passed, and an unhandled error occurs that
was produced by the github.com/pkg/errors package, we will now
emit the stack trace. Much easier for debugging purposes.
The change to use a Goroutine for pumping output causes a hang
when an error occurs. This is because we unconditionally block
on the <-done channel, even though the failure means the done
will actually never occur. This changes the logic to only wait
on the channel if we successfully began the operation in question.
Instead of doing the logic to see if a type has YAML tags and then
dispatching based on that to use either the direct go-yaml marshaller
or the one that works in terms of JSON tags, let's just say that we
always add YAML tags as well, and use go-yaml directly.
Previously, config information was stored per stack. With this change,
we now allow config values which apply to every stack a program may
target.
When passed without the `-s <stack>` argument, `pulumi config`
operates on the "global" configuration. Stack specific information can
be modified by passing an explicit stack.
Stack specific configuration overwrites global configuration.
Conside the following Pulumi.yaml:
```
name: hello-world
runtime: nodejs
description: a hello world program
config:
hello-world:config:message Hello, from Pulumi
stacks:
production:
config:
hello-world:config:message Hello, from Production
```
This program contains a single configuration value,
"hello-world:config:message" which has the value "Hello, from Pulumi"
when the program is activated into any stack except for "production"
where the value is "Hello, from Production".
Instead of having information stored in the checkpoint file, save it
in the Pulumi.yaml file. We introduce a new section `stacks` which
holds information specific to a stack.
Next, we'll support adding configuration information that applies
to *all* stacks for a Program and allow the stack specific config to
overwrite or augment it.
This will allow us to marhsall and unmarshall the structure using the
go-yaml package directly, instead of the current way we handle YAML
which is to treat it as JSON and use the JSON marshaller behind the
scenes.
By having the explicit tags and using go-yaml directly, we can ensure
the resulting order of the resulting document's properties matches the
go type instead of just being lexigraphicaly sorted.
Long term, we probably want to stop using go-yaml or other packages in
favor of parsing the YAML file into some sort of DOM that we can use
to retain comments and other formatting in the file.
