// // STORY #######################################################################
|
|
// //
|
|
// // 1. Migrate from CircleCI to GitHub Actions
|
|
// // - extract existing build pipeline into Dagger
|
|
// // - run the pipeline locally
|
|
// // - run the pipeline in GitHub Actions
|
|
// //
|
|
// // 2. Pipeline is up to 9x quicker (40s vs 370s)
|
|
// // - optimistic branching, as pipelines were originally intended
|
|
// // - use our own hardware - Linode g6-dedicated-8
|
|
// // - predictable runs, no queuing
|
|
// // - caching is buildkit layers
|
|
// //
|
|
// // 3. Open Telemetry integration out-of-the-box
|
|
// // - visualise all steps in Jaeger UI
|
