buildkite-go

A Go library and client for the Buildkite API. This project draws a lot of its structure and testing methods from go-github.

Usage

To get the package, execute:

go get github.com/buildkite/go-buildkite/v5

Simple shortened example for listing all pipelines:

import (
    "github.com/buildkite/go-buildkite/v5"
    "github.com/alecthomas/kingpin/v2"
)

var (
    apiToken = kingpin.Flag("token", "API token").Required().String()
    org = kingpin.Flag("org", "Organization slug").Required().String()
)

client, err := buildkite.NewOpts(buildkite.WithTokenAuth(*apiToken))

if err != nil {
    log.Fatalf("client config failed: %s", err)
}

pipelines, _, err := client.Pipelines.List(*org, nil)

Migrating to v5 update payloads

Version 5 changes update request structs so PATCH requests can distinguish "leave this field unchanged" from "send this field with an empty value".

Update fields that can be cleared now use buildkite.Optional[T]. The zero value omits the field. Wrap values with buildkite.Some(...) when the field should be sent, including empty strings, empty maps, empty slices, 0, or false.

Use initialized empty slices and maps when the API expects [] or {}. Nil slices and maps wrapped with buildkite.Some(...) are encoded as null.

_, _, err := client.Pipelines.Update(ctx, org, pipelineSlug, buildkite.UpdatePipeline{
    Description:              buildkite.Some(""),
    Tags:                     buildkite.Some([]string{}),
    SkipQueuedBranchBuilds:   buildkite.Some(false),
})

_, _, err := client.PipelineSchedules.Update(ctx, org, pipelineSlug, scheduleID, buildkite.UpdatePipelineSchedule{
    Env:     buildkite.Some(map[string]string{}),
    Enabled: buildkite.Some(false),
})

Leaving an Optional[T] unset omits that field from the PATCH body:

_, _, err := client.Clusters.Update(ctx, org, clusterID, buildkite.ClusterUpdate{
    Name: buildkite.Some("macOS builders"),
    // Description is unchanged.
})

Some create/update request types were split so create calls keep plain required values while update calls use presence-aware fields:

• ClusterTokenCreateUpdate is now ClusterTokenCreate and ClusterTokenUpdate.
• PipelineTemplateCreateUpdate is now PipelineTemplateCreate and PipelineTemplateUpdate.
• CreateTeam is still used for team creation; UpdateTeam is now used for team updates.
• TestSuitesService.Update now takes TestSuiteUpdate.

See the examples directory for additional examples.

Note: not all API features are supported by go-buildkite just yet. If you need a feature, please make an issue or submit a pull request.
