Adds a new experimental `pulumi watch` CLI command which can be used for inner loop development on a Pulumi stack. This command is only available currently via `PULUMI_EXPERIMENTAL=true` while in active development.
The `watch` command does the following:
1. Watches the workspace (the tree rooted at the `Pulumi.yaml` file) for changes
2. Triggers an `update` to the stack whenever there is a change
3. Streams output containing summaries of key update events as well as logs from any resources under management into a combined CLI output
Part of https://github.com/pulumi/pulumi/issues/3448.
The PULUMI_EXPERIMENTAL flag also makes`query` and `policy` available.
I noticed that we block startup on performing the version check.
Although we cache the latest version from the server for 24 hours,
this check also runs the `brew --prefix pulumi` command which
(at least for me) takes between 0.5-1s on average. Thus, running it
in parallel, which requires no shared state, saves us that amount
of time in the end to end execution time. Notably, this shortens the
amount of time from command start to the first "previewing..." message.
This does change the user experience: rather than reporting the
new version up front, we report it at the end after running the
requested command (both on success and failure). This is what I'd
have assumed we'd want anyway, and what many other tools do, but
it's entirely reasonable if folks object to the change in UX.
The @pulumi/pulumi TypScript SDK exposes `streamInvoke`, which returns a
(potentially infinite) stream of responses. This currently is _assumed_
to be infinite, in that there is no way to signal cancellation, and
prevents Pulumi from being able to clean up when we're finished using
the results of the `streamInvoke`.
This commit will introduce a `StreamInvokeResult` type, which is an
`AsyncIterable` that also exposes a `cancel` function, whih does just
this.
Use it like this:
// `streamInvoke` to retrieve all updates to any `Deployment`, enumerate 0
// updates from the stream, then `cancel` giving the Kubernetes provider to
// clean up and close gracefully.
const deployments = await streamInvoke("kubernetes:kubernetes:watch", {
group: "apps", version: "v1", kind: "Deployment",
break;
});
deployments.cancel();
This change adds support for lists and maps in config. We now allow
lists/maps (and nested structures) in `Pulumi.<stack>.yaml` (or
`Pulumi.<stack>.json`; yes, we currently support that).
For example:
```yaml
config:
proj:blah:
- a
- b
- c
proj:hello: world
proj:outer:
inner: value
proj:servers:
- port: 80
```
While such structures could be specified in the `.yaml` file manually,
we support setting values in maps/lists from the command line.
As always, you can specify single values with:
```shell
$ pulumi config set hello world
```
Which results in the following YAML:
```yaml
proj:hello world
```
And single value secrets via:
```shell
$ pulumi config set --secret token shhh
```
Which results in the following YAML:
```yaml
proj:token:
secure: v1:VZAhuroR69FkEPTk:isKafsoZVMWA9pQayGzbWNynww==
```
Values in a list can be set from the command line using the new
`--path` flag, which indicates the config key contains a path to a
property in a map or list:
```shell
$ pulumi config set --path names[0] a
$ pulumi config set --path names[1] b
$ pulumi config set --path names[2] c
```
Which results in:
```yaml
proj:names
- a
- b
- c
```
Values can be obtained similarly:
```shell
$ pulumi config get --path names[1]
b
```
Or setting values in a map:
```shell
$ pulumi config set --path outer.inner value
```
Which results in:
```yaml
proj:outer:
inner: value
```
Of course, setting values in nested structures is supported:
```shell
$ pulumi config set --path servers[0].port 80
```
Which results in:
```yaml
proj:servers:
- port: 80
```
If you want to include a period in the name of a property, it can be
specified as:
```
$ pulumi config set --path 'nested["foo.bar"]' baz
```
Which results in:
```yaml
proj:nested:
foo.bar: baz
```
Examples of valid paths:
- root
- root.nested
- 'root["nested"]'
- root.double.nest
- 'root["double"].nest'
- 'root["double"]["nest"]'
- root.array[0]
- root.array[100]
- root.array[0].nested
- root.array[0][1].nested
- root.nested.array[0].double[1]
- 'root["key with \"escaped\" quotes"]'
- 'root["key with a ."]'
- '["root key with \"escaped\" quotes"].nested'
- '["root key with a ."][100]'
Note: paths that contain quotes can be surrounded by single quotes.
When setting values with `--path`, if the value is `"false"` or
`"true"`, it will be saved as the boolean value, and if it is
convertible to an integer, it will be saved as an integer.
Secure values are supported in lists/maps as well:
```shell
$ pulumi config set --path --secret tokens[0] shh
```
Will result in:
```yaml
proj:tokens:
- secure: v1:wpZRCe36sFg1RxwG:WzPeQrCn4n+m4Ks8ps15MxvFXg==
```
Note: maps of length 1 with a key of “secure” and string value are
reserved for storing secret values. Attempting to create such a value
manually will result in an error:
```shell
$ pulumi config set --path parent.secure foo
error: "secure" key in maps of length 1 are reserved
```
**Accessing config values from the command line with JSON**
```shell
$ pulumi config --json
```
Will output:
```json
{
"proj:hello": {
"value": "world",
"secret": false,
"object": false
},
"proj:names": {
"value": "[\"a\",\"b\",\"c\"]",
"secret": false,
"object": true,
"objectValue": [
"a",
"b",
"c"
]
},
"proj:nested": {
"value": "{\"foo.bar\":\"baz\"}",
"secret": false,
"object": true,
"objectValue": {
"foo.bar": "baz"
}
},
"proj:outer": {
"value": "{\"inner\":\"value\"}",
"secret": false,
"object": true,
"objectValue": {
"inner": "value"
}
},
"proj:servers": {
"value": "[{\"port\":80}]",
"secret": false,
"object": true,
"objectValue": [
{
"port": 80
}
]
},
"proj:token": {
"secret": true,
"object": false
},
"proj:tokens": {
"secret": true,
"object": true
}
}
```
If the value is a map or list, `"object"` will be `true`. `"value"` will
contain the object as serialized JSON and a new `"objectValue"` property
will be available containing the value of the object.
If the object contains any secret values, `"secret"` will be `true`, and
just like with scalar values, the value will not be outputted unless
`--show-secrets` is specified.
**Accessing config values from Pulumi programs**
Map/list values are available to Pulumi programs as serialized JSON, so
the existing
`getObject`/`requireObject`/`getSecretObject`/`requireSecretObject`
functions can be used to retrieve such values, e.g.:
```typescript
import * as pulumi from "@pulumi/pulumi";
interface Server {
port: number;
}
const config = new pulumi.Config();
const names = config.requireObject<string[]>("names");
for (const n of names) {
console.log(n);
}
const servers = config.requireObject<Server[]>("servers");
for (const s of servers) {
console.log(s.port);
}
```
Allow the user to specify a set of resources to replace via the
`--replace` flag on the CLI. This can be combined with `--target` to
replace a specific set of resources without changing any other
resources. `--target-replace` is shorthand for `--replace urn --target urn`.
Fixes#2643.
If a stack output includes a `Resource`, we will as of a recent change
always show the output diff, but this diff will potentially include
unknowns, leading to spurious output like:
```
+ namePrefix : output<string>
```
These changes supress these diffs by adding a special key to the POJO
we generate for resources *during preview only* that indicates that the
POJO represents a Pulumi resource, then stripping all adds of unknown
values from diffs for objects marked with that key.
Fixes#3314.
This is needed to add support for objects (maps/lists) to config. Once this has been merged, we can merge the associated change in the service, then merge the overall change in the CLI.
