Alertmanager: External Receiver Files

External Receiver Files

Add support for loading receiver configurations from external YAML files, keeping backwards compatibility with inline receivers in the main config.

Design Decisions

  • New YAML field receiver_files (list of glob patterns) on Config struct
  • Mutually exclusive with inline receivers: error if both are set
  • Glob patterns supported (e.g. receivers/*.yml), consistent with templates
  • Relative paths resolved against config file directory (same as templates)
  • Each file contains a YAML list of Receiver objects (one or more per file)

Alertmanager UI rewrite analysis

Estimation generated by Claude Sonnet 4.5 Thinking model, instructed to:

  • analyze Alertmanager UI code
  • analyze Prometheus UI code
  • Estimate lines of code needed to migrate from current implementation to something similar to prometheus code structure and quality

Current Codebase Analysis

Existing Elm UI (ui/app/)

  • 49 Elm source files (~8,500-9,500 lines total)
  • 4 Elm test files (~400-500 lines)

Fix Helm release stuck in a pending status
  1. Get the release from Kubernetes 
    $ kubectl get secret sh.helm.release.v1.<release>.v<version> -o yaml > release.yaml
  2. Open the release.yaml file in an editor and copy data.release value (or use Bash skills)
  3. Extract the release payload 
    $ echo <release value> | base64 -D | base64 -D | gunzip > release
  4. Open release file and change status from pending-rollback to deployed
