示例1: getRunningAllocs
// getRunningAllocs returns a slice of allocation id's running on the node
func getRunningAllocs(client *api.Client, nodeID string) ([]*api.Allocation, error) {
var allocs []*api.Allocation
// Query the node allocations
nodeAllocs, _, err := client.Nodes().Allocations(nodeID, nil)
// Filter list to only running allocations
for _, alloc := range nodeAllocs {
