func (*ASG) DetailName 

func (a *ASG) DetailName() string

DetailName returns the name of the detail field associated with the ASG

func (*ASG) Empty 

func (a *ASG) Empty() bool

Empty returns true if the ASG does not contain any instances

func (*ASG) Instances 

func (a *ASG) Instances() []*Instance

Instances returns a slice of the instances associated with the ASG

func (*ASG) Name 

func (a *ASG) Name() string

Name returns the name of the ASG

func (*ASG) RegionName 

func (a *ASG) RegionName() string

RegionName returns the name of the region associated with the ASG

func (*ASG) StackName 

func (a *ASG) StackName() string

type ASGName 

type ASGName string

ASGName is the app-stack-detail-sequence name of an ASG

type Account 

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

Account represents the set of clusters associated with an App that reside in one AWS account (e.g., "prod", "test").

func (*Account) AppName 

func (a *Account) AppName() string

AppName returns the name of the app associated with this Account

func (*Account) CloudProvider 

func (a *Account) CloudProvider() string

CloudProvider returns the cloud provider (e.g., "aws")

func (*Account) Clusters 

func (a *Account) Clusters() []*Cluster

Clusters returns a slice of clusters

func (*Account) Name 

func (a *Account) Name() string

Name returns the name of the account associated with this account

func (*Account) RegionNames 

func (a *Account) RegionNames() []string

RegionNames returns the name of the regions that clusters in this account are running in

func (*Account) StackNames 

func (a *Account) StackNames() []string

StackNames returns the names of the stacks associated with this account

type AccountInfo 

type AccountInfo struct {
	CloudProvider string
	Clusters      ClusterMap
}

AccountInfo tracks the provider and the clusters

type AccountName 

type AccountName string

AccountName is the name of a cloud account

type App 

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

App represents an application

func NewApp 

func NewApp(name string, data AppMap) *App

NewApp constructs a new App

func (App) Accounts 

func (a App) Accounts() []*Account

Accounts returns a slice of accounts

func (*App) EligibleInstanceGroups 

func (app *App) EligibleInstanceGroups(cfg chaosmonkey.AppConfig) []grp.InstanceGroup

EligibleInstanceGroups returns a slice of InstanceGroups that represent groups of instances that are eligible for termination.

Note that this code does not check for violations of mininum time between terminations. Chaos Monkey checks that precondition immediately before termination, not when considering groups of eligible instances.

The way instances are divided into group will depend on

  • the grouping configuration for the app (cluster, stack, app)
  • whether regions are independent

The returned InstanceGroups are guaranteed to contain at least one instance each

Preconditions:

  • app is enabled for Chaos Monkey

func (App) Name 

func (a App) Name() string

Name returns the name of an app

type AppMap 

type AppMap map[AccountName]AccountInfo

AppMap is a map that tracks info about an app

type Cluster 

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

Cluster represents what Spinnaker refers to as a "cluster", which contains app-stack-detail. Every ASG is associated with exactly one cluster. Note that clusters can span regions

func (*Cluster) ASGs 

func (c *Cluster) ASGs() []*ASG

ASGs returns a slice of ASGs

func (*Cluster) AccountName 

func (c *Cluster) AccountName() string

AccountName returns the name of the account associated with this cluster

func (*Cluster) AppName 

func (c *Cluster) AppName() string

AppName returns the name of the app associated with this cluster

func (*Cluster) CloudProvider

type ClusterMap 

type ClusterMap map[ClusterName]map[RegionName]map[ASGName][]InstanceID

ClusterMap maps cluster name to information about instances by region and ASG

type ClusterName 

type ClusterName string

ClusterName is the app-stack-detail name of a cluster

type Deployment

	// Apps sends App objects over a channel
	Apps(c chan<- *App, appNames []string)

	// GetApp retrieves a single App
	GetApp(name string) (*App, error)

	// AppNames returns the names of all apps
