Overview ¶

Package resilience judges whether the data plane would keep serving if the control plane went away.

Constants ¶

const (
	StatusPass    = "pass"
	StatusFail    = "fail"
	StatusWarn    = "warn"

const (
	CheckRouteSnapshot = "route_snapshot"
	CheckCertCache     = "cert_cache"
	CheckAgentLink     = "agent_link"
	CheckContainers    = "container_restart"
	CheckTelemetry     = "telemetry_buffer"
)

Check IDs.

const FixSaveSnapshot = "save_snapshot"

FixSaveSnapshot is the fix that rewrites the route snapshot from the applied config.

Types ¶

type Check ¶

type Check struct {
	ID     string `json:"id"`
	Status string `json:"status"`
	Detail string `json:"detail"`
	Fix    string `json:"fix,omitempty"`
}

Check is one survival property of the ingress or a node.

type IngressInput ¶

type IngressInput struct {
	SnapshotEnabled bool
	SavedAt         time.Time
	SaveError       string
	// Verified is set when the snapshot was opened as a restart would; VerifyErr is the outcome.
	Verified    bool
	VerifyErr   error
	ConfigBytes int
	CertKeys    int
	CertErr     error
}

IngressInput is what the control plane knows about the persisted ingress state.

type NodeInput ¶

type NodeInput struct {
	ID       string
	Name     string
	Local    bool
	Status   string
	LastSeen *time.Time
}

NodeInput is one node as the control plane last saw it.

type Report ¶

type Report struct {
	GeneratedAt time.Time `json:"generated_at"`
	Simulated   bool      `json:"simulated"`
	Overall     string    `json:"overall"`
	Scopes      []Scope   `json:"scopes"`
}

Report is the whole resilience check.

func Evaluate ¶

func Evaluate(now time.Time, simulate bool, in IngressInput, nodes []NodeInput) Report

Evaluate builds the report. simulate adds the restart dry run to the ingress checks.

type Scope ¶

type Scope struct {
	Kind   string  `json:"kind"`
	ID     string  `json:"id"`
	Name   string  `json:"name"`
	Checks []Check `json:"checks"`
}

Scope groups the checks of the ingress or one node.
