示例1: evaluateNodePlan
// evaluateNodePlan is used to evalute the plan for a single node,
// returning if the plan is valid or if an error is encountered
func evaluateNodePlan(snap *state.StateSnapshot, plan *structs.Plan, nodeID string) (bool, error) {
// If this is an evict-only plan, it always 'fits' since we are removing things.
if len(plan.NodeAllocation[nodeID]) == 0 {
return true, nil
}
// Get the node itself
node, err := snap.NodeByID(nodeID)
if err != nil {
return false, fmt.Errorf("failed to get node '%s': %v", nodeID, err)
}
// If the node does not exist or is not ready for schduling it is not fit
// XXX: There is a potential race between when we do this check and when
// the Raft commit happens.
if node == nil || node.Status != structs.NodeStatusReady || node.Drain {
return false, nil
}
// Get the existing allocations that are non-terminal
existingAlloc, err := snap.AllocsByNodeTerminal(nodeID, false)
if err != nil {
return false, fmt.Errorf("failed to get existing allocations for '%s': %v", nodeID, err)
}
// Determine the proposed allocation by first removing allocations
// that are planned evictions and adding the new allocations.
proposed := existingAlloc

remove = append(remove, update...)
}
