	// DefaultExecTimeout specifies the maximum time a task is allowed to run

	// not specified in the project file. exec_timeout_secs can be specified
	// only at the project and task level.

	// DefaultHeartbeatInterval is the interval after which agent sends a

	DefaultPreTimeout = 2 * time.Hour

	// maxTeardownGroupTimeout specifies the duration after when the
	// teardown_group should time out and stop the current command.
	// this cannot be set higher than the evergreen.MaxTeardownGroupThreshold
	// because hosts will be considered idle if they have been tearing down
	// a task group for longer than that time.
	MaxTeardownGroupTimeout = 3 * time.Minute

	// DefaultPostTimeout specifies the default duration after when the post or
	// teardown_task block should time out and stop the current command.

Types

type LogOutputType

type LogOutputType string

LogOutput represents the output locations for the agent's logs.

const (
	// LogOutputFile indicates that the agent will log to a file.
	LogOutputFile LogOutputType = "file"
	// LogOutputStdout indicates that the agent will log to standard output.
	LogOutputStdout LogOutputType = "stdout"
)

type Mode

type Mode string

Mode represents a mode that the agent will run in.

const (
	// HostMode indicates that the agent will run in a host.
	HostMode Mode = "host"
	// PodMode indicates that the agent will run in a pod's container.
	PodMode Mode = "pod"
)
