[apitype] Add a JSON schema for deployments. (#8002)
This schema can be used to validate the contents of a Pulumi deployment.
If a deployment validates against this schema, it should be considered
syntactically valid, though it may contain certain classes of semantic
errors (e.g. references to unknown resources in dependency lists,
dependency cycles, etc.).

This schema is not yet used for validation in practice and may not be
entirely accurate.

These changes also add this schema (and the schemas on which it depends)
to the developer documentation. jsonschema2md.go has been updated to
support multi-file schemas.

* Fix malformed resource value bug

PR #6125 introduced a bug by marshaling resource
ids as PropertyValues, but not handling that case on
the unmarshaling side. The previous code assumed
that the id was a simple string value. This bug prevents
any stack update operations (preview, update, destroy,
refresh). Since this change was already
released, we must now handle both cases in the
unmarshaling code.

* Add resource ref unit tests for the Go SDK. (#6142)

This reapplies 3d505912b8.

Revert "Fix resource-ref-as-ID marshaling. (#6125)" (#6167) 2021-01-21 20:37:40 +00:00
Pat Gavlin 2f0dba23ab
Fix resource-ref-as-ID marshaling. (#6125)
When marshaling a resource reference as its ID (i.e. when
opts.KeepResources is false, as it will be in the case of downlevel SDKs
and resource providers), we must take care to marshal/unmarshal an empty
ID as the unknown property value.

This includes the following changes to the resource ref APIs:

- Bifurcate resource reference creation into two methods: one for
  creating references to custom resources and one for creating
  references to component resources.
- Store the ID in a resource reference as a PropertyValue s.t. it can be
  computed.
- Add a helper method for retrieving the ID as a string + an indicator of
  whether or not the reference has an ID.

Fixes #5939.

Fix a few issues with resource references. (#5804)
- Differentiate between resource references that have no ID (i.e. because
  the referenced resource is not a CustomResource) and resource references
  that have IDs that are not known. This is necessary for proper
  backwards-compatible serialization of resource references.
- Fix the key that stores a resource reference's package version in the
  .NET, NodeJS, and Python SDKs.
- Ensure that the resource monitor's marshalling/unmarshalling  of inputs
  and outputs to/from calls to `Construct` retain resource references as
  appropriate.
- Fix serialization behavior for resources -> resource references in the
  Go SDK: if a resource's ID is unknown, it should still be serialized
  as a resource reference, albeit a reference with an unknown ID.

Pat Gavlin 3d2e31289a
Add support for serialized resource references. (#5041)
Resources are serialized as their URN, ID, and package version. Each
Pulumi package is expected to register itself with the SDK. The package
will be invoked to construct appropriate instances of rehydrated
resources. Packages are distinguished by their name and their version.

This is the foundation of cross-process resources.

Related to #2430.

[codegen/hcl2] Fixes for RewriteConversions. (#4743)
- Typecheck in all cases where a type may have changed
- Do not perform literal conversions if the type is already correct
- Perform literal conversions before checking to see if a call to
  `__convert` is required. This catches cases such as string literals
  passed where ints are required. Without this change, that form in
  particular generates a bare number literal rather than a number
  literal wrapped in a `__convert`.

Avoid replace on second update with import applied (#4403)
After importing some resources, and running a second update with the
import still applied, an unexpected replace would occur. This wouldn't
happen for the vast majority of resources, but for some it would.

It turns out that the resources that trigger this are ones that use a
different format of identifier for the import input than they do for the
ID property.

Before this change, we would trigger an import-replacement when an
existing resource's ID property didn't match the import property, which
would be the case for the small set of resources where the input
identifier is different than the ID property.

To avoid this, we now store the `importID` in the statefile, and
compare that to the import property instead of comparing the ID.

Cache ciphertext for secret properties. (#3183)
This caching is enabled by wrapping the `secrets.Manager` returned by
`DefaultSecretsProvider.OfType` in an outer `secrets.Manager` that
cooperates with `stack.{Serialize,Deserialize}PropertyValue`. Ciphertext
is cached on a per-secret-instance basis (i.e. not a per-plaintext-value
basis). Cached ciphertext is only reused if the plaintext for the secret
value has not changed. Entries are inserted into the cache upon both
encryption and decryption so that values that originated from ciphertext
and that have not changed can aoid re-encryption.

Contributes to #3178.

Support additional cloud secrets providers (#2994)
Adds support for additional cloud secrets providers (AWS KMS, Azure KeyVault, Google Cloud KMS, and HashiCorp Vault) as the encryption backend for Pulumi secrets. This augments the previous choice between using the app.pulumi.com-managed secrets encryption or a fully-client-side local passphrase encryption.

This is implemented using the Go Cloud Development Kit support for pluggable secrets providers.

Like our cloud storage backend support which also uses Go Cloud Development Kit, this PR also bleeds through to users the URI scheme's that the Go CDK defines for specifying each of secrets providers - like `awskms://alias/LukeTesting?region=us-west-2` or `azurekeyvault://mykeyvaultname.vault.azure.net/keys/mykeyname`.

Also like our cloud storage backend support, this PR doesn't solve for how to configure the cloud provider client used to resolve the URIs above - the standard ambient credentials are used in both cases. Eventually, we will likely need to provide ways for both of these features to be configured independently of each other and of the providers used for resource provisioning.

Addition of Custom Timeouts (#2885)

Support aliases for renaming, re-typing, or re-parenting resources (#2774)
Adds a new resource option `aliases` which can be used to rename a resource.  When making a breaking change to the name or type of a resource or component, the old name can be added to the list of `aliases` for a resource to ensure that existing resources will be migrated to the new name instead of being deleted and replaced with the new named resource.

There are two key places this change is implemented. 

The first is the step generator in the engine.  When computing whether there is an old version of a registered resource, we now take into account the aliases specified on the registered resource.  That is, we first look up the resource by its new URN in the old state, and then by any aliases provided (in order).  This can allow the resource to be matched as a (potential) update to an existing resource with a different URN.

The second is the core `Resource` constructor in the JavaScript (and soon Python) SDKs.  This change ensures that when a parent resource is aliased, that all children implicitly inherit corresponding aliases.  It is similar to how many other resource options are "inherited" implicitly from the parent.

Four specific scenarios are explicitly tested as part of this PR:
1. Renaming a resource
2. Adopting a resource into a component (as the owner of both component and consumption codebases)
3. Renaming a component instance (as the owner of the consumption codebase without changes to the component)
4. Changing the type of a component (as the owner of the component codebase without changes to the consumption codebase)
4. Combining (1) and (3) to make both changes to a resource at the same time

Matt Ellis 31bd463264 Gracefully handle the case where secrets_provider is uninitalized
A customer reported an issue where operations would fail with the
following error:

```
error: could not deserialize deployment: unknown secrets provider type
```

The problem here was the customer's deployment had a
`secrets_provider` section which looked like the following:

```
"secrets_providers": {
    "type": ""
}
```

And so our code to try to construct a secrets manager from this thing
would fail, as our registry does not contain any information about a
provider with an empty type.

We do two things in this change:

1. When serializing a deployment, if there is no secrets manager,
don't even write the `secrets_provider` block. This helps for cases
where we are roundtripping deployments that did not have a provider
configured (i.e. they were older stacks that did not use secrets)

2. When deserializing, if we see an empty secrets provider like the
above, interpret it to mean "this deployment has no secrets". We set
up a decrypter such that if it ends up haiving secrets, we panic
eagerly (since this is a logical bug in our system somewhere).

Matt Ellis 88012c4d96 Enable "cloud" and "local" secrets managers across the system
We move the implementations of our secrets managers in to
`pkg/secrets` (which is where the base64 one lives) and wire their use
up during deserialization.

It's a little unfortunate that for the passphrase based secrets
manager, we have to require `PULUMI_CONFIG_PASSPHRASE` when
constructing it from state, but we can make more progress with the
changes as they are now, and I think we can come up with some ways to
mitigate this problem a bit (at least make it only a problem for cases
where you are trying to take a stack reference to another stack that
is managed with local encryption).

Matt Ellis db18ee3905 Retain the SecretsManager that was used to deserialize a deployment
We have many cases where we want to do the following:

re-use the existing manager.

Half of the call sites didn't care about these values and with the

into the CLI itself, as it was the only place that cared to do
this (so it could display things to end users).

For cloud backed stacks, this was already returning nil and due to the
fact that we no longer include config in the checkpoint for local

Removing this helps clean stuff up and is should make some future
refactorings around custom secret managers easier to land.

We can always add it back later if we miss it (and make it actually do
the right thing!)
2019-05-10 17:07:52 -07:00
Matt Ellis cc74ef8471 Encrypt secret values in deployments
When constructing a Deployment (which is a plaintext representation of
a Snapshot), ensure that we encrypt secret values. To do so, we
introduce a new type `secrets.Manager` which is able to encrypt and
decrypt values. In addition, it is able to reflect information about
itself that can be stored in the deployment such that we can
deserialize the deployment into a snapshot (decrypting the values in
the process) without external knowledge about how it was encrypted.

The ability to do this is import for allowing stack references to
work, since two stacks may not use the same manager (or they will use
the same type of manager, but have different state).

The state value is stored in plaintext in the deployment, so it **must
not** contain sensitive data.

A sample manager, which just base64 encodes and decodes strings is
provided, as it useful for testing. We will allow it to be varried
soon.

Matt Ellis 529645194e Track secrets inside the engine
A new `Secret` property value is introduced, and plumbed across the
engine.

- When Unmarshalling properties /from/ RPC calls, we instruct the
  marshaller to retain secrets, since we now understand them in the
  rest of the engine.

- When Marshalling properties /to/ RPC calls, we use or tracked data
  to understand if the other side of the connection can accept
  secrets. If they can, we marshall them in a similar manner to assets
  where we have a special object with a signiture specific for secrets
  and an underlying value (which is the /plaintext/ value). In cases
  where the other end of the connection does not understand secrets,
  we just drop the metadata and marshal the underlying value as we
  normally would.

- Any secrets that are passed across the engine events boundary are
  presently passed as just `[secret]`.

- When persisting secret values as part of a deployment, we use a rich
  object so that we can track the value is a secret, but right now the
  underlying value is not actually encrypted.

Pat Gavlin 1ecdc83a33 Implement more precise delete-before-replace semantics. (#2369)
This implements the new algorithm for deciding which resources must be
deleted due to a delete-before-replace operation.

We need to compute the set of resources that may be replaced by a
change to the resource under consideration. We do this by taking the
complete set of transitive dependents on the resource under
consideration and removing any resources that would not be replaced by
changes to their dependencies. We determine whether or not a resource
may be replaced by substituting unknowns for input properties that may
change due to deletion of the resources their value depends on and
calling the resource provider's Diff method.

This is perhaps clearer when described by example. Consider the
following dependency graph:

  A
__|__
B   C
|  _|_
D  E F

In this graph, all of B, C, D, E, and F transitively depend on A. It may
be the case, however, that changes to the specific properties of any of
those resources R that would occur if a resource on the path to A were
deleted and recreated may not cause R to be replaced. For example, the
edge from B to A may be a simple dependsOn edge such that a change to
B does not actually influence any of B's input properties. In that case,
neither B nor D would need to be deleted before A could be deleted.

In order to make the above algorithm a reality, the resource monitor
interface has been updated to include a map that associates an input
property key with the list of resources that input property depends on.
Older clients of the resource monitor will leave this map empty, in
which case all input properties will be treated as depending on all
dependencies of the resource. This is probably overly conservative, but
it is less conservative than what we currently implement, and is
certainly correct.

Add a list of in-flight operations to the deployment (#1759)
* Add a list of in-flight operations to the deployment

This commit augments 'DeploymentV2' with a list of operations that are
currently in flight. This information is used by the engine to keep
track of whether or not a particular deployment is in a valid state.

The SnapshotManager is responsible for inserting and removing operations
from the in-flight operation list. When the engine registers an intent
to perform an operation, SnapshotManager inserts an Operation into this
list and saves it to the snapshot. When an operation completes, the
SnapshotManager removes it from the snapshot. From this, the engine can
infer that if it ever sees a deployment with pending operations, the
Pulumi CLI must have crashed or otherwise abnormally terminated before
seeing whether or not an operation completed successfully.

To remedy this state, this commit also adds code to 'pulumi stack
import' that clears all pending operations from a deployment, as well as
code to plan generation that will reject any deployments that have
pending operations present.

At the CLI level, if we see that we are in a state where pending
operations were in-flight when the engine died, we'll issue a
human-friendly error message that indicates which resources are in a bad
state and how to recover their stack.

* CR: Multi-line string literals, renaming in-flight -> pending

* CR: Add enum to apitype for operation type, also name status -> type for clarity

* Fix the yaml type

* Fix missed renames

* Add implementation for lifecycle_test.go

Implement first-class providers. (#1695)
### First-Class Providers
These changes implement support for first-class providers. First-class
providers are provider plugins that are exposed as resources via the
Pulumi programming model so that they may be explicitly and multiply
instantiated. Each instance of a provider resource may be configured
differently, and configuration parameters may be source from the
outputs of other resources.

### Provider Plugin Changes
In order to accommodate the need to verify and diff provider
configuration and configure providers without complete configuration
information, these changes adjust the high-level provider plugin
interface. Two new methods for validating a provider's configuration
and diffing changes to the same have been added (`CheckConfig` and
`DiffConfig`, respectively), and the type of the configuration bag
accepted by `Configure` has been changed to a `PropertyMap`.

These changes have not yet been reflected in the provider plugin gRPC
interface. We will do this in a set of follow-up changes. Until then,
these methods are implemented by adapters:
- `CheckConfig` validates that all configuration parameters are string
  or unknown properties. This is necessary because existing plugins
  only accept string-typed configuration values.
- `DiffConfig` either returns "never replace" if all configuration
  values are known or "must replace" if any configuration value is
  unknown. The justification for this behavior is given
  [here](https://github.com/pulumi/pulumi/pull/1695/files#diff-a6cd5c7f337665f5bb22e92ca5f07537R106)
- `Configure` converts the config bag to a legacy config map and
  configures the provider plugin if all config values are known. If any
  config value is unknown, the underlying plugin is not configured and
  the provider may only perform `Check`, `Read`, and `Invoke`, all of
  which return empty results. We justify this behavior becuase it is
  only possible during a preview and provides the best experience we
  can manage with the existing gRPC interface.

### Resource Model Changes
Providers are now exposed as resources that participate in a stack's
dependency graph. Like other resources, they are explicitly created,
may have multiple instances, and may have dependencies on other
resources. Providers are referred to using provider references, which
are a combination of the provider's URN and its ID. This design
addresses the need during a preview to refer to providers that have not
yet been physically created and therefore have no ID.

All custom resources that are not themselves providers must specify a
single provider via a provider reference. The named provider will be
used to manage that resource's CRUD operations. If a resource's
provider reference changes, the resource must be replaced. Though its
URN is not present in the resource's dependency list, the provider
should be treated as a dependency of the resource when topologically
sorting the dependency graph.

Finally, `Invoke` operations must now specify a provider to use for the
invocation via a provider reference.

### Engine Changes
First-class providers support requires a few changes to the engine:
- The engine must have some way to map from provider references to
  provider plugins. It must be possible to add providers from a stack's
  checkpoint to this map and to register new/updated providers during
  the execution of a plan in response to CRUD operations on provider
  resources.
- In order to support updating existing stacks using existing Pulumi
  programs that may not explicitly instantiate providers, the engine
  must be able to manage the "default" providers for each package
  referenced by a checkpoint or Pulumi program. The configuration for
  a "default" provider is taken from the stack's configuration data.

The former need is addressed by adding a provider registry type that is
responsible for managing all of the plugins required by a plan. In
addition to loading plugins froma checkpoint and providing the ability
to map from a provider reference to a provider plugin, this type serves
as the provider plugin for providers themselves (i.e. it is the
"provider provider").

The latter need is solved via two relatively self-contained changes to
plan setup and the eval source.

During plan setup, the old checkpoint is scanned for custom resources
that do not have a provider reference in order to compute the set of
packages that require a default provider. Once this set has been
computed, the required default provider definitions are conjured and
prepended to the checkpoint's resource list. Each resource that
requires a default provider is then updated to refer to the default
provider for its package.

While an eval source is running, each custom resource registration,
resource read, and invoke that does not name a provider is trapped
before being returned by the source iterator. If no default provider
for the appropriate package has been registered, the eval source
synthesizes an appropriate registration, waits for it to complete, and
records the registered provider's reference. This reference is injected
into the original request, which is then processed as usual. If a
default provider was already registered, the recorded reference is
used and no new registration occurs.

### SDK Changes
These changes only expose first-class providers from the Node.JS SDK.
- A new abstract class, `ProviderResource`, can be subclassed and used
  to instantiate first-class providers.
- A new field in `ResourceOptions`, `provider`, can be used to supply
  a particular provider instance to manage a `CustomResource`'s CRUD
  operations.
- A new type, `InvokeOptions`, can be used to specify options that
  control the behavior of a call to `pulumi.runtime.invoke`. This type
  includes a `provider` field that is analogous to
  `ResourceOptions.provider`.

Save resources obtained from ".get" in the snapshot (#1654)
* Protobuf changes to record dependencies for read resources

* Add a number of tests for read resources, especially around replacement

* Place read resources in the snapshot with "external" bit set

Fixes pulumi/pulumi#1521. This commit introduces two new step ops: Read
and ReadReplacement. The engine generates Read and ReadReplacement steps
when servicing ReadResource RPC calls from the language host.

* Fix an omission of OpReadReplace from the step list

* Rebase against master

* Transition to use V2 Resources by default

* Add a semantic "relinquish" operation to the engine

If the engine observes that a resource is read and also that the
resource exists in the snapshot as a non-external resource, it will not
delete the resource if the IDs of the old and new resources match.

* Typo fix

* CR: add missing comments, DeserializeDeployment -> DeserializeDeploymentV2, ID check

Alex Clemmer f037c7d143 Checkpoint resource initialization errors
When a resource fails to initialize (i.e., it is successfully created,
but fails to transition to a fully-initialized state), and a user
subsequently runs `pulumi update` without changing that resource, our
CLI will fail to warn the user that this resource is not initialized.

This commit begins the process of allowing our CLI to report this by
storing a list of initialization errors in the checkpoint.
