Struct HealthProbe 

pub struct HealthProbe {
    pub argv: Vec<String>,
    pub interval: Duration,
    pub timeout: Duration,
    pub retries: u32,
    pub start_period: Duration,
    pub start_interval: Duration,
    pub startup_grace: Duration,
}

A healthcheck resolved to argv and durations.

Fields

argv: Vec<String>

interval: Duration

timeout: Duration

retries: u32

start_period: Duration

start_interval: Duration

startup_grace: Duration

How long a replica that has not passed since it (re)started may fail before its failures count: start_period when set, else HealthProbe::default_grace.

Implementations

impl HealthProbe

pub fn default_grace(interval: Duration, retries: u32) -> Duration

The startup grace of a healthcheck without start_period: twice the failure budget a running replica gets (interval * retries), so a slow first start (OIDC discovery, migrations, a JVM) is not taken for a hang; at least 60s, as a fast probe’s budget (5s x 3) is shorter than many starts; at most 5 minutes, so a replica that never comes up still fails its rollout in bounded time.

pub fn failure_counts(&self, passed: bool, since_start: Duration) -> bool

Whether a failed probe counts toward retries. A replica that has not passed since it (re)started is starting: it stays out of the load balancer, and its failures count only once the startup grace is over. After a pass, they count once start_period is over.
