# Spinnaker
Use the "schema" syntax to create type-safe and unit-testable Spinnaker pipelines.
## Usage
```dhall
let Spinnaker = ./package.dhall
let myProject = { name = "my-project", team = "my-team", email = "[email protected]" }
let spinnaker = Spinnaker.schemas
let waitTimeId = "timeToWait"
let pipelineTemplate =
spinnaker.PipelineTemplate::{
, id = myProject.name
, metadata = spinnaker.Metadata::{
, name = "Wait Stage"
, description = "Demonstrative wait stage."
, owner = myProject.email
}
, variables = [ spinnaker.Variable::{ type = "int", name = waitTimeId } ]
, pipeline = spinnaker.Pipeline::{
, lastModifiedBy = Some myProject.team
, stages =
[ spinnaker.Stage::{
, refId = "1"
, name = "my wait stage"
, type = "wait"
, stageEnabled = Some spinnaker.StageEnabled::{
, expression = "SUCCESS"
}
, waitTime = Some
( spinnaker.NatOrString.String
"\${ templateVariables.${waitTimeId} }"
)
}
]
}
}
let _testIdIsProjectName = assert : pipelineTemplate.id === myProject.name
in pipelineTemplate
```
## Examples
### Toy PipelineTemplate
```bash
dhall-to-json --file ./examples/TrivialPipelineTemplate.dhall
```
### Progressive Deployment
### Automatic Deployment
When pushing a git tag with `vX` to GitHub, the following pipeline will kick off a deploy to staging:
```bash
dhall-to-json <<< '(./examples/ProgressiveDeploy/AutomaticPipeline.dhall).staging'
```
Here's all you gotta change for production:
```bash
dhall-to-json <<< '(./examples/ProgressiveDeploy/AutomaticPipeline.dhall).production'
```
### Manual Deployment
When you want to deploy some branch, tag, or commit, use the following pipeline:
```bash
dhall-to-json <<< '(./examples/ProgressiveDeploy/ManualPipeline.dhall).staging'
```
Here's all you gotta change for production:
```bash
dhall-to-json <<< '(./examples/ProgressiveDeploy/ManualPipeline.dhall).staging'
```
### Type-check existing JSON
#### Disclaimer
Spinnaker has no OpenAPI spec. Yikes. Therefore these types, defaults, etc are hand-typed. They are likely not exhaustive. Certain types of stages, preconditions, and other unions are probably not done. If you run into a type error when converting an existing pipeline to Dhall, feel free to change the types and make a PR!
The best we can do until they create a spec is use their ["functional" test fixtures](https://github.com/spinnaker/deck/blob/e4b0d1849a6ce9da2554f08493136eb7aa722148/test/functional/cypress/fixtures/google/pipelines_list/pipelineConfigs.json).
Run this locally and you'll see a massive list of pipelines converted to Dhall. If this doesn't error, it means you've got a valid Dhall expression that matches our best approximation of Spinnaker's types!
```bash
json-to-dhall '(List ./types/Pipeline.dhall)' --file ./fixtures/pipelines.json
```
#### Type-check your own JSON
```bash
json-to-dhall ./types/Pipeline.dhall --file ./path/to/your/pipeline.json
```
If you want to check a stage, a pipeline template, whatever, use the appropriate Dhall type!
```bash
json-to-dhall ./types/Stage.dhall --file ./path/to/your/stage.json
json-to-dhall ./types/PipelineTemplate.dhall --file ./path/to/your/pipelineTemplate.json
```
