Struct HealthcheckSpec 

pub struct HealthcheckSpec {
    pub test: Vec<String>,
    pub interval: Duration,
    pub timeout: Duration,
    pub retries: u32,
    pub start_period: Duration,
}

Healthcheck resolved from the manifest, with duration strings already parsed into std::time::Duration values.

For postgres resources the default test is ["CMD", "pg_isready", "-U", <user>]. For redis it is ["CMD", "redis-cli", "ping"]. Generic container and dockerfile resources have no default: the manifest must provide one explicitly if a healthcheck is needed.

Default timing values when the manifest omits them: interval = 5s, timeout = 3s, retries = 5, start_period = 5s.

Example

use lightshuttle_spec::HealthcheckSpec;
use std::time::Duration;

let hc = HealthcheckSpec {
    test: vec!["CMD".into(), "pg_isready".into(), "-U".into(), "postgres".into()],
    interval: Duration::from_secs(5),
    timeout: Duration::from_secs(3),
    retries: 5,
    start_period: Duration::from_secs(5),
};
assert_eq!(hc.retries, 5);

Fields

test: Vec<String>

Command the runtime runs to probe container health.

The first element is typically "CMD" or "CMD-SHELL" as per the Docker healthcheck specification.

interval: Duration

Time between consecutive health checks.

timeout: Duration

Maximum wall-clock time a single check invocation may take.

retries: u32

Number of consecutive failures before the container is considered unhealthy.

start_period: Duration

Grace period after container start before health checks begin.
