type Chaoskube ¶
type Chaoskube struct {
// a kubernetes client object
Client kubernetes.Interface
// a label selector which restricts the pods to choose from
Labels labels.Selector
// an annotation selector which restricts the pods to choose from
Annotations labels.Selector
// a namespace selector which restricts the pods to choose from
Namespaces labels.Selector
// a list of weekdays when termination is suspended
ExcludedWeekdays []time.Weekday
// a list of time periods of a day when termination is suspended
ExcludedTimesOfDay []util.TimePeriod
// a list of days of a year when termination is suspended
ExcludedDaysOfYear []time.Time
// the timezone to apply when detecting the current weekday
Timezone *time.Location
// an instance of logrus.StdLogger to write log messages to
Logger log.FieldLogger
// dry run will not allow any pod terminations
DryRun bool
// a function to retrieve the current time
Now func() time.Time
}
Chaoskube represents an instance of chaoskube
func New ¶
func New(client kubernetes.Interface, labels, annotations, namespaces labels.Selector, excludedWeekdays []time.Weekday, excludedTimesOfDay []util.TimePeriod, excludedDaysOfYear []time.Time, timezone *time.Location, logger log.FieldLogger, dryRun bool) *Chaoskube
New returns a new instance of Chaoskube. It expects: * a Kubernetes client to connect to a Kubernetes API * label, annotation and/or namespace selectors to reduce the amount of possible target pods * a list of weekdays, times of day and/or days of a year when chaos mode is disabled * a time zone to apply to the aforementioned time-based filters * a logger implementing logrus.FieldLogger to send log output to * whether to enable/disable dry-run mode
func (*Chaoskube) Candidates ¶
func (c *Chaoskube) Candidates() ([]v1.Pod, error)
Candidates returns the list of pods that are available for termination. It returns all pods that match the configured label, annotation and namespace selectors.
func (*Chaoskube) DeletePod ¶
func (c *Chaoskube) DeletePod(victim v1.Pod) error
DeletePod deletes the given pod. It will not delete the pod if dry-run mode is enabled.
func (*Chaoskube) TerminateVictim ¶ added in v0.5.0
func (c *Chaoskube) TerminateVictim() error
TerminateVictim picks and deletes a victim. It respects the configured excluded weekdays, times of day and days of a year filters.
