00:00:00,001 --> 00:00:01,434
[No Audio]

2
00:00:01,434 --> 00:00:05,934
Let's create our first node using docker-machine create command.

3
00:00:06,001 --> 00:00:07,967
We are using virtualbox as the

4
00:00:07,967 --> 00:00:11,567
driver and we are naming our node manager.

5
00:00:11,567 --> 00:00:15,467
While the node is being created, you can see the Docker

6
00:00:15,467 --> 00:00:19,534
machine is using a custom OS called boot2docker,

7
00:00:19,534 --> 00:00:23,101
and it is using its ISO image to install it

8
00:00:23,101 --> 00:00:27,434
on a virtual machine. For your information, boot2docker

9
00:00:27,434 --> 00:00:30,367
is a minimal Linux OS customized for

10
00:00:30,367 --> 00:00:33,234
containers to run smoothly being lightweight at

11
00:00:33,234 --> 00:00:37,167
the same time. Let's see if the node has been created.

12
00:00:37,267 --> 00:00:40,234
Use docker-machine ls command.

13
00:00:40,234 --> 00:00:45,801
And manager has been created, it is running Docker version 18.06,

14
00:00:45,801 --> 00:00:49,767
and it also has its dedicated IP which is

15
00:00:49,767 --> 00:00:55,301
192.168.99.100. Similarly, we can also

16
00:00:55,301 --> 00:00:58,801
create a couple of more nodes, named worker-1 and

17
00:00:58,801 --> 00:01:01,967
worker-2. Once we are done with our creation, we

18
00:01:01,967 --> 00:01:06,934
can run docker-machine ls again to see if both are running perfectly.

19
00:01:07,701 --> 00:01:09,134
And here they are.

20
00:01:09,867 --> 00:01:14,734
Let's stop this manager node using docker-machine stop manager command.

21
00:01:14,734 --> 00:01:17,434
When we list our nodes, manager

22
00:01:17,434 --> 00:01:21,667
exists but it is stopped. We can start it again

23
00:01:21,667 --> 00:01:24,501
using docker-machine start manager command.

24
00:01:24,601 --> 00:01:28,001
If we want to find specific information about a node,

25
00:01:28,001 --> 00:01:31,767
we can use docker-machine ip manager which provides

26
00:01:31,967 --> 00:01:36,634
IP of manager node. Similarly, we can get IPs of

27
00:01:36,634 --> 00:01:39,801
worker- 1 and worker-2 node. Just like every

28
00:01:39,801 --> 00:01:42,734
other object in Docker ecosystem, we can use

29
00:01:42,734 --> 00:01:45,601
inspect command with docker-machine node as well

30
00:01:45,634 --> 00:01:48,667
use docker-machine inspect command followed by the

31
00:01:48,667 --> 00:01:53,234
name of the node, which is manager here. As you can see,

32
00:01:53,234 --> 00:01:55,567
the inspect command provides a lot of

33
00:01:55,567 --> 00:01:58,701
information about the manager node, including its

34
00:01:58,701 --> 00:02:05,801
MachineName, IPAddress, SSHUser and Port, SSHKeyPath

35
00:02:05,801 --> 00:02:08,366
and some other useful information.

36
00:02:08,934 --> 00:02:12,434
Finally, let's ssh into our manager node using

37
00:02:12,434 --> 00:02:17,101
docker-machine ssh command, followed by name of the node

38
00:02:17,101 --> 00:02:19,301
which again here is manager.

39
00:02:19,301 --> 00:02:22,901
We have navigated to the shell of manager node.
