示例1: SubmitPlan
// SubmitPlan is used to submit a plan for consideration. This allows
// the worker to act as the planner for the scheduler.
func (w *Worker) SubmitPlan(plan *structs.Plan) (*structs.PlanResult, scheduler.State, error) {
// Check for a shutdown before plan submission
if w.srv.IsShutdown() {
return nil, nil, fmt.Errorf("shutdown while planning")
}
defer metrics.MeasureSince([]string{"nomad", "worker", "submit_plan"}, time.Now())
// Add the evaluation token to the plan
plan.EvalToken = w.evalToken
// Setup the request
req := structs.PlanRequest{
Plan: plan,
WriteRequest: structs.WriteRequest{
Region: w.srv.config.Region,
},
}
var resp structs.PlanResponse
SUBMIT:
// Make the RPC call
if err := w.srv.RPC("Plan.Submit", &req, &resp); err != nil {
w.logger.Printf("[ERR] worker: failed to submit plan for evaluation %s: %v",
plan.EvalID, err)
if w.shouldResubmit(err) && !w.backoffErr(backoffBaselineSlow, backoffLimitSlow) {
goto SUBMIT
}
return nil, nil, err
} else {
w.logger.Printf("[DEBUG] worker: submitted plan for evaluation %s", plan.EvalID)
w.backoffReset()
}
// Look for a result
result := resp.Result
if result == nil {
return nil, nil, fmt.Errorf("missing result")
}
// Check if a state update is required. This could be required if we
// planning based on stale data, which is causing issues. For example, a
// node failure since the time we've started planning or conflicting task
// allocations.
var state scheduler.State
if result.RefreshIndex != 0 {
// Wait for the raft log to catchup to the evaluation
w.logger.Printf("[DEBUG] worker: refreshing state to index %d for %q", result.RefreshIndex, plan.EvalID)
if err := w.waitForIndex(result.RefreshIndex, raftSyncLimit); err != nil {
return nil, nil, err
}
// Snapshot the current state
snap, err := w.srv.fsm.State().Snapshot()
if err != nil {
return nil, nil, fmt.Errorf("failed to snapshot state: %v", err)
}
state = snap
}
// Return the result and potential state update
return result, state, nil
}
