WEBVTT 1 00:00.000 --> 00:03.360 Okay friends, so here is the validation solution. 2 00:03.360 --> 00:06.560 So the first thing that I'm going to have to do is to use dnf to download the 3 00:06.560 --> 00:07.380 rail system 4 00:07.380 --> 00:08.880 roles on my control mode. 5 00:08.880 --> 00:14.520 So I'll say sudo dnf install rail-system-rolls and to enter. 6 00:14.520 --> 00:18.330 As it transpires I already have these roles on my system, so I don't have to do 7 00:18.330 --> 00:18.680 anything 8 00:18.680 --> 00:19.680 further. 9 00:19.680 --> 00:23.720 If you don't you would just say why, to confirm the install and then hit enter. 10 00:23.720 --> 00:27.230 Now what I'm going to have to do is to write a playbook that uses a rail system 11 00:27.230 --> 00:27.640 role to 12 00:27.640 --> 00:31.160 deploy a post-gracio server on each of my managed devices. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 12 00:27.640 --> 00:31.160 deploy a post-gracio server on each of my managed devices. 13 00:31.160 --> 00:34.320 Now to call the best place to go here is enter the documentation. 14 00:34.320 --> 00:40.080 So if I go into user-share-dulk-rail-system-rolls, do an LS, what it is I want 15 00:40.080 --> 00:40.840 to configure 16 00:40.840 --> 00:42.280 is a post-gracio server. 17 00:42.280 --> 00:46.830 Now we actually see the post-gracio directory here, so a good idea would be to 18 00:46.830 --> 00:47.480 go into that 19 00:47.480 --> 00:48.480 particular directory. 20 00:48.480 --> 00:52.440 So if I do an LS, here we can see an example basic playbook and what I will do 21 00:52.440 --> 00:53.000 is I will 22 00:53.000 --> 00:55.080 just copy that basic example. 23 00:55.080 --> 00:57.680 And all I'm going to do is copy it to my home directory. 24 00:57.680 --> 01:01.840 So let's use the tilde logo or tilde character, should I say, and to enter, let WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 24 00:57.680 --> 01:01.840 So let's use the tilde logo or tilde character, should I say, and to enter, let 25 01:01.840 --> 01:02.440 's do a CD. 26 01:02.440 --> 01:04.120 We'll now back to the home directory. 27 01:04.120 --> 01:07.320 If I do an LS, here is the example basic playbook. 28 01:07.320 --> 01:10.520 So if I go into this using Vim, check this out right here. 29 01:10.520 --> 01:11.960 Here is the example we have. 30 01:11.960 --> 01:15.720 Now what we have to do is to configure post-gracio on all of our managed 31 01:15.720 --> 01:16.480 devices. 32 01:16.480 --> 01:20.520 Now right now this particular playbook is just targeting the control node. 33 01:20.520 --> 01:24.920 So we want to make a modification here and I will change this to all. 34 01:24.920 --> 01:29.320 As per the instruction, the version of post-gracio should be version 13. 35 01:29.320 --> 01:33.320 So let's go and change the version here from 10 to 13. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 35 01:29.320 --> 01:33.320 So let's go and change the version here from 10 to 13. 36 01:33.320 --> 01:36.000 And what I'm also going to have to do is to create an additional task. 37 01:36.000 --> 01:39.920 So if I just say tasks, colon and then have my hyphen give the task a name, the 38 01:39.920 --> 01:40.440 name should 39 01:40.440 --> 01:41.960 be validation task. 40 01:41.960 --> 01:45.200 And all I have to do is to print out the message automation is fun. 41 01:45.200 --> 01:48.980 So I will use the debug module and then the message is going to be, as we just 42 01:48.980 --> 01:50.080 said, automation 43 01:50.080 --> 01:51.080 is fun. 44 01:51.080 --> 01:52.080 Perfect. 45 01:52.080 --> 01:53.080 Let's just save these changes. 46 01:53.080 --> 01:55.400 Now before I run this, let me clear the screen. 47 01:55.400 --> 02:01.870 And if I go to my managed devices, if I say systemctl status on post-gracio and WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 47 01:55.400 --> 02:01.870 And if I go to my managed devices, if I say systemctl status on post-gracio and 48 02:01.870 --> 02:03.080 to enter, 49 02:03.080 --> 02:06.680 notice right now we don't have a post-gracio service on the device. 50 02:06.680 --> 02:08.760 The same thing is true on the blue box. 51 02:08.760 --> 02:12.900 However, now that we have this role, I can just say Ansible Playbook, example 52 02:12.900 --> 02:13.800 basic playbook 53 02:13.800 --> 02:18.670 and to enter the playbook begins to execute and the changes are beginning to be 54 02:18.670 --> 02:19.280 made. 55 02:19.280 --> 02:24.000 And we can see the review, we have 17 OKs with seven changes, 17 skip tasks, 56 02:24.000 --> 02:25.040 nothing unreachable, 57 02:25.040 --> 02:26.040 no fears. 58 02:26.040 --> 02:28.960 And look at the very end here, we also have our validation task saying 59 02:28.960 --> 02:30.320 automation is fun. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 59 02:28.960 --> 02:30.320 automation is fun. 60 02:30.320 --> 02:33.670 If we go to our devices, the managed devices that is, let's start with yellow 61 02:33.670 --> 02:34.240 box, just 62 02:34.240 --> 02:38.720 add a warp and to enter, notice that right now we have a post-gracio database 63 02:38.720 --> 02:39.160 server 64 02:39.160 --> 02:41.400 running on our device. 65 02:41.400 --> 02:46.570 Similarly, let's go to the blue box, do a systemctl status on post-gracio, hit 66 02:46.570 --> 02:47.240 enter. 67 02:47.240 --> 02:51.780 As we can see here, we also have an active and running post-gracio database 68 02:51.780 --> 02:52.480 server. 69 02:52.480 --> 02:55.240 So that is us for our validation on Ansible roles. 70 02:55.240 --> 02:58.160 I hope this has been informative for you and I'd like to thank you for viewing.
