Documentation

Overview

Package inventory keeps each host's cached instance inventory warm by refreshing it on a schedule, so UI/API reads are served without a live podman sweep and an unreachable host never stalls a request.

Types

type Poller 

type Poller struct {
	Svc      Refresher
	Interval time.Duration
	Timeout  time.Duration
	// contains filtered or unexported fields
}

Poller periodically refreshes every host's inventory into the service cache. It mirrors internal/prune.Scheduler: an immediate first pass so a fresh start warms within one cycle, per-tick panic recovery, a per-host timeout so one hung host can't bleed into the next cycle, and Wait() for clean shutdown.

func (*Poller) Start 

func (p *Poller) Start(ctx context.Context, hostsFn func() []string)

Start launches the ticker loop until ctx is cancelled. hostsFn returns the current host ids on each tick (so SIGHUP host reloads are picked up).

func (*Poller) Wait 

func (p *Poller) Wait()

Wait blocks until the poller goroutine has exited after ctx cancellation.

type Refresher 

type Refresher interface {
	RefreshHost(ctx context.Context, host string) error
}

Refresher refreshes one host's cached inventory. Implemented by *instance.Service.RefreshHost.
