Types ¶

type Engine ¶

type Engine struct {
	// contains filtered or unexported fields
}

func New ¶

func New(c config.Config, client drone.Client, fleet cluster.Cluster) *Engine

func (*Engine) Downscale ¶

func (e *Engine) Downscale(ctx context.Context, agents []cluster.NodeId) error

func (*Engine) Plan ¶

func (e *Engine) Plan(ctx context.Context) (*Plan, error)

Plan determines whether there is a need to upscale or downscale the agent cluster based on current capacity and build traffic

func (*Engine) Start ¶

func (e *Engine) Start(ctx context.Context)

func (*Engine) Upscale ¶

func (e *Engine) Upscale(ctx context.Context, count int) error

type Plan ¶

type Plan struct {
	// contains filtered or unexported fields
}

Plan describes the scaling action that needs to be taken, as determined by autoscaler's planner engine. It also supplies the data required to carry out the action.

func (*Plan) MarshalJSON ¶

func (p *Plan) MarshalJSON() ([]byte, error)

func (*Plan) NodesToDestroy ¶

func (p *Plan) NodesToDestroy() []cluster.NodeId

NodesToDestroy returns IDs of agent machines to destroy when downscaling

func (*Plan) RequiresDownscaling ¶

func (p *Plan) RequiresDownscaling() bool

RequiresDownscaling returns true when we have extra compute capacity that must be shed

func (*Plan) RequiresUpscaling ¶

func (p *Plan) RequiresUpscaling() bool

RequiresUpscaling returns true when more agents must be added

func (*Plan) String ¶

func (p *Plan) String() string

serialization methods for better representation of Plan in logs

func (*Plan) UpscaleCount ¶

func (p *Plan) UpscaleCount() int

UpscaleCount returns the number of nodes to add to the agent cluster when upscaling

type StageFilter ¶

type StageFilter func(stage *drone.Stage) bool

StageFilter is a filter function applied to a single drone stage
