[No Audio]

2
00:00:02,134 --> 00:00:05,301
Now that both the nodes have joined the cluster as

3
00:00:05,301 --> 00:00:10,067
workers, let's verify it using docker node ls command.

4
00:00:10,101 --> 00:00:14,834
Take a note, that this is part of Docker's Swarm command line.

5
00:00:14,834 --> 00:00:17,234
Once we hit enter, we get all

6
00:00:17,234 --> 00:00:19,801
of the three nodes along with their hostnames.

7
00:00:19,801 --> 00:00:22,767
All of them have their status as Ready and

8
00:00:22,767 --> 00:00:26,401
availability as Active. And if you can notice,

9
00:00:26,401 --> 00:00:29,634
manager also has the status of being Leader.

10
00:00:29,767 --> 00:00:32,500
This is applicable when we have a cluster with more

11
00:00:32,500 --> 00:00:35,634
than one manager. In which case, one of the

12
00:00:35,634 --> 00:00:39,101
managers will act as Leader. There is no confusion

13
00:00:39,101 --> 00:00:41,834
here since we only have one manager and two worker

14
00:00:41,834 --> 00:00:45,567
nodes, so our manager will be Leader by default.

15
00:00:45,567 --> 00:00:48,401
Now we can inspect our manager and worker nodes

16
00:00:48,401 --> 00:00:50,734
from managers shell itself.

17
00:00:50,867 --> 00:00:54,967
Let's type docker node inspect followed by self,

18
00:00:54,967 --> 00:01:00,134
along with '--pretty' flag. We are mentioning self, because manager wants

19
00:01:00,134 --> 00:01:03,734
to inspect itself. And as you can see, what we get

20
00:01:03,734 --> 00:01:08,767
is the node ID, its Hostname, joining timestamp,

21
00:01:08,901 --> 00:01:13,634
Status, and some other information like Platform,

22
00:01:13,634 --> 00:01:16,967
Resources, Engine Version, which is Docker engine

23
00:01:16,967 --> 00:01:23,101
version. Here it is 18.0 6.1 Community Edition and

24
00:01:23,101 --> 00:01:26,467
some security certificates. We can hit the command

25
00:01:26,467 --> 00:01:29,767
for worker-1 and 2 as well and we get

26
00:01:29,801 --> 00:01:32,401
respective information about both of them.

27
00:01:32,401 --> 00:01:35,801
As you can see, all of these three nodes have different

28
00:01:35,801 --> 00:01:38,467
IP, but rest of the things are pretty much the

29
00:01:38,467 --> 00:01:41,434
same. Of course, the roles are different,

30
00:01:41,434 --> 00:01:44,301
which will be explored in further demos.
