API Changes:
- Fixes validation in template CRUD API to be closer to how the running
alertmanager will use the template. Should remove some incorrect
validation errors.
- Adds some missing default placeholder labels to receiver testing that
are used during template testing but missing during receiver testing
Template Preview:
- Replaced basic preview with a readonly CodeEditor for better whitespace
and alignment clarity (also adds support for future syntax highlighting
in template previews for upcoming webhook payload templates)
Template Selector (Receiver Form):
- Refactored to use same components as Template editor for preview.
- Fixed preview to work with multi-definition templates
- Fixed copy to correctly copy the template contents instead of
{{ template "<name>" . }}.
Template Editor:
- Fixed detection of when to display functions vs snippets in multi-line
expressions
What
This aims to define the unified alerting API as code. It generates OpenAPI definitions from go structs. It also generates server/route stubs based on our documentation.
Running
make - regenerate everything - documentation and server stubs.
make serve - regenerate the Swagger document, and host rendered docs on port 80. view api
Requires
Why
The current state of Swagger extraction from golang is relatively limited. It's easier to generate server stubs from an existing Swagger doc, as there are limitations with producing a Swagger doc from a hand-written API stub. The current extractor instead relies on comments describing the routes, but the comments and actual implementation may drift, which we don't want to allow.
Instead, we use a hybrid approach - we define the types in Golang, with comments describing the routes, in a standalone package with minimal dependencies. From this, we produce a Swagger doc, and then turn the Swagger doc back into a full-blown server stub.
Stability
We have some endpoints that we document publicly as being stable, and others that we consider unstable. The stable endpoints are documented in api.json, where all endpoints are available in post.json.
To stabilize an endpoint, add the stable tag to its route comment:
// swagger:route GET /provisioning/contact-points provisioning stable RouteGetContactpoints
