WEBVTT 1 00:00.000 --> 00:02.640 So friends, let's walk through the validation challenge. 2 00:02.640 --> 00:06.000 So the very first thing that I asked you to do was to create two new groups in 3 00:06.000 --> 00:06.880 your inventory 4 00:06.880 --> 00:10.990 called Brazil and Japan. And we're going to place one of the managed devices in 5 00:10.990 --> 00:11.360 the Brazil 6 00:11.360 --> 00:14.460 group and the other in the Japan groups. All I will do here is I will go into 7 00:14.460 --> 00:15.760 my inventory right now. 8 00:15.760 --> 00:19.520 And all I will do is use my square brackets and create a group called Brazil. 9 00:19.520 --> 00:23.120 And I will place the blue box in that particular group. And I will also create 10 00:23.120 --> 00:23.920 a group called 11 00:23.920 --> 00:28.130 Japan once again placing the other device in that particular group. So let's 12 00:28.130 --> 00:28.800 just write and 13 00:28.800 --> 00:32.000 quit. Save those changes. Now I'm going to create a playbook which creates WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 13 00:28.800 --> 00:32.000 quit. Save those changes. Now I'm going to create a playbook which creates 14 00:32.000 --> 00:32.640 three files in the 15 00:32.640 --> 00:38.240 10th directory of the device in the Japan group called Japan 1.txt, Japan 2.txt 16 00:38.240 --> 00:40.240 and Japan 3.txt 17 00:40.240 --> 00:45.530 ensuring that I have a loop. So let's just create a file called validation.YML 18 00:45.530 --> 00:46.080 and I'm going to 19 00:46.080 --> 00:49.600 insert mode, have my three hyphens at the top. Let's give this a playbook. Let 20 00:49.600 --> 00:49.920 's give the 21 00:49.920 --> 00:54.060 playbook a name just called validation. So the host I'm going to target is 22 00:54.060 --> 00:55.040 going to be the all 23 00:55.040 --> 00:58.640 group and I'm going to define my tasks right here. So the first task will be 24 00:58.640 --> 01:00.400 create multiple files WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 24 00:58.640 --> 01:00.400 create multiple files 25 01:00.400 --> 01:05.480 on the Japan devices. And all I will do is use the Ansible built in shell 26 01:05.480 --> 01:06.880 module. And all I will do 27 01:06.880 --> 01:10.650 is I will say touch and then within my double curly braces, I will specify the 28 01:10.650 --> 01:11.200 item that I'm 29 01:11.200 --> 01:14.630 going to be looping through. Then I'm going to specify my loop keyword to 30 01:14.630 --> 01:15.520 actually define the 31 01:15.520 --> 01:18.920 loop itself. So I'll have an array object here. And I'm going to have to create 32 01:18.920 --> 01:19.440 a file called 33 01:19.440 --> 01:24.080 Japan 1 Japan 2 in Japan 3 all with the extension dot txt. There's the first 34 01:24.080 --> 01:25.600 file Japan 1, there's 35 01:25.600 --> 01:31.330 Japan 2 and the last object in the array will be Japan 3.txt. Now I only want WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 35 01:25.600 --> 01:31.330 Japan 2 and the last object in the array will be Japan 3.txt. Now I only want 36 01:31.330 --> 01:32.480 to execute this 37 01:32.480 --> 01:35.940 when we have a particular condition. And that is when I happen to have the 38 01:35.940 --> 01:37.760 group Japan and my 39 01:37.760 --> 01:41.340 group underscore names magic variable. They are not specified the name of the 40 01:41.340 --> 01:42.160 next task. I'll just 41 01:42.160 --> 01:47.290 say create multiple files on the Brazil devices. So use the same module again 42 01:47.290 --> 01:48.720 the Ansible built in 43 01:48.720 --> 01:53.080 shell. And then I will say touch and I'm going to reference my item once again, 44 01:53.080 --> 01:53.760 once again within 45 01:53.760 --> 01:58.510 double curly braces. And now I'm going to do specify my loop keywords and begin 46 01:58.510 --> 01:59.440 an array. The first 47 01:59.440 --> 02:05.040 object is going to be Brazil 1 dot txt. And the second element will be Brazil 2 WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 47 01:59.440 --> 02:05.040 object is going to be Brazil 1 dot txt. And the second element will be Brazil 2 48 02:05.040 --> 02:06.160 dot txt. Once again, 49 02:06.160 --> 02:09.420 we have our conditional statements. And that is going to define that this 50 02:09.420 --> 02:11.040 should only ever execute 51 02:11.040 --> 02:15.160 when we happen to be a member of the Brazil group again using that group 52 02:15.160 --> 02:16.000 underscore names 53 02:16.000 --> 02:19.760 magic variable. Oh, and just before I do this, you may have noticed what I'm 54 02:19.760 --> 02:20.400 going to have to do 55 02:20.400 --> 02:24.080 is to specify that these happen to be created within the temp directory. So I 56 02:24.080 --> 02:25.040 'll say touch forward 57 02:25.040 --> 02:29.190 slash temp forward slash item. And again, do that for the one below. Okay, so 58 02:29.190 --> 02:30.400 let's press escape WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 58 02:29.190 --> 02:30.400 let's press escape 59 02:30.400 --> 02:35.970 colon wq to writing quits. And I will just say Ansible playbook validation dot 60 02:35.970 --> 02:37.200 yml and to enter 61 02:37.200 --> 02:41.430 and the playbook executes and appears that we have successfully changed our 62 02:41.430 --> 02:42.800 devices. So let's go 63 02:42.800 --> 02:46.900 and quickly validate here I am on the blue box if I go into the temp directory 64 02:46.900 --> 02:47.840 to an LS, 65 02:47.840 --> 02:52.480 we can indeed see we have the Brazil one and Brazil two dot txt files. Whereas 66 02:52.480 --> 02:53.440 in the yellow 67 02:53.440 --> 02:56.960 box if I go into the temp directory to an LS, we can actually see the files are 68 02:56.960 --> 02:58.240 called Japan one 69 02:58.240 --> 03:03.740 Japan two and Japan three dot txt. So that is us for our introduction and to WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 69 02:58.240 --> 03:03.740 Japan two and Japan three dot txt. So that is us for our introduction and to 70 03:03.740 --> 03:04.240 loops and 71 03:04.240 --> 03:07.420 conditionals. Hope it's been informative for you and I'd like to thank you for 72 03:07.420 --> 03:07.920 viewing.
