Types

type Executor

type Executor struct {
	// ExecutorConfig provides the executor configuration
	ExecutorConfig
	// contains filtered or unexported fields
}

Executor represents the phases of execution in a Buildkite Job. It's run as a sub-process of the buildkite-agent and finishes at the conclusion of a job.

Historically (prior to v3) the job executor was a shell script, but was ported to Go for portability and testability.

func New

func New(conf ExecutorConfig) *Executor

New returns a new executor instance

func (*Executor) Cancel

func (e *Executor) Cancel() error

Cancel interrupts any running shell processes and causes the job to stop

func (*Executor) CheckoutPhase

func (e *Executor) CheckoutPhase(ctx context.Context) error

CheckoutPhase creates the build directory and makes sure we're running the build at the right commit.

func (*Executor) CommandPhase

func (e *Executor) CommandPhase(ctx context.Context) (hookErr error, commandErr error)

CommandPhase determines how to run the build, and then runs it

func (*Executor) PluginPhase

func (e *Executor) PluginPhase(ctx context.Context) error

PluginPhase is where plugins that weren't filtered in the Environment phase are checked out and made available to later phases

func (*Executor) Run

func (e *Executor) Run(ctx context.Context) (exitCode int)

Run the job and return the exit code

func (*Executor) VendoredPluginPhase

func (e *Executor) VendoredPluginPhase(ctx context.Context) error

VendoredPluginPhase is where plugins that are included in the checked out code are added
