示例1: pruneNetworkAndVerify

func pruneNetworkAndVerify(c *check.C, d *daemon.Swarm, kept, pruned []string) {
	_, err := d.Cmd("network", "prune", "--force")
	c.Assert(err, checker.IsNil)
	out, err := d.Cmd("network", "ls", "--format", "{{.Name}}")

示例2: TestAPISwarmLeaderElection

func (s *DockerSwarmSuite) TestAPISwarmLeaderElection(c *check.C) {
	// Create 3 nodes
	d1 := s.AddDaemon(c, true, true)
	d2 := s.AddDaemon(c, true, true)
	d3 := s.AddDaemon(c, true, true)

	// assert that the first node we made is the leader, and the other two are followers
	c.Assert(d1.GetNode(c, d1.NodeID).ManagerStatus.Leader, checker.True)
	c.Assert(d1.GetNode(c, d2.NodeID).ManagerStatus.Leader, checker.False)
	c.Assert(d1.GetNode(c, d3.NodeID).ManagerStatus.Leader, checker.False)

	d1.Stop(c)

	var (
		leader    *daemon.Swarm   // keep track of leader
		followers []*daemon.Swarm // keep track of followers
	)
	checkLeader := func(nodes ...*daemon.Swarm) checkF {
		return func(c *check.C) (interface{}, check.CommentInterface) {
			// clear these out before each run
			leader = nil
			followers = nil
			for _, d := range nodes {
				if d.GetNode(c, d.NodeID).ManagerStatus.Leader {

				} else {
					followers = append(followers, d)
				}
			}

			if leader == nil {
				return false, check.Commentf("no leader elected")
			}

			return true, check.Commentf("elected %v", leader.ID())
		}
	}

	// wait for an election to occur
	waitAndAssert(c, defaultReconciliationTimeout, checkLeader(d2, d3), checker.True)

	// assert that we have a new leader
	c.Assert(leader, checker.NotNil)

	// Keep track of the current leader, since we want that to be chosen.
	stableleader := leader

	// add the d1, the initial leader, back
	d1.Start(c)

	// TODO(stevvooe): may need to wait for rejoin here

	// wait for possible election
	waitAndAssert(c, defaultReconciliationTimeout, checkLeader(d1, d2, d3), checker.True)
	// pick out the leader and the followers again

	// verify that we still only have 1 leader and 2 followers
	c.Assert(leader, checker.NotNil)
	c.Assert(followers, checker.HasLen, 2)
	// and that after we added d1 back, the leader hasn't changed
	c.Assert(leader.NodeID, checker.Equals, stableleader.NodeID)
