Functions

func GenerateChain

func GenerateChain(commonConfigs []CommonConfig) []v1.ServiceUnitConfig

GenerateChain generates ServiceUnitConfigs for chain topology of given tiers.

func GenerateFanout

func GenerateFanout(commonConfigs []CommonConfig, fanoutDegree uint64) []v1.ServiceUnitConfig

GenerateFanout generates ServiceUnitConfigs for fanout topology of given tiers. []CommonConfig should contain configs for each tier. Note that it is not for each service. so leaves will have same config for example.

func NewDefaultDeploymentSpec

func NewDefaultDeploymentSpec() v1.DeploymentSpec

deployment:

replicas: 1
resources:
  limits:
    cpu: 500m
    memory: 1Gi
  requests:
    cpu: 500m
    memory: 1Gi

func NewLeafService

func NewLeafService(version string, tier, index uint64) v1.ServiceUnitConfig

• server: action: get variant: rest route: get tasks:
• adapter: stressor: name: cpu-stressor variant: cpu iters: 500 threads: 2 resiliency: # callTimeout: "2.5ms" # no timeout # taskTimeout: "1s" # no timeout retry: disabled: true circuitBreaker: disabled: true

func NewTrunkOrBranchService

func NewTrunkOrBranchService(version string, tier, index uint64, isEdge bool, fanout uint64, timeout time.Duration, adaptiveTimeout v1.AdaptiveTimeoutSpec) v1.ServiceUnitConfig

adapters:

• server: action: read variant: rest route: get tasks:
