1 00:00:01,200 --> 00:00:01,440 All right. 2 00:00:01,470 --> 00:00:02,050 Let's get to it. 3 00:00:02,070 --> 00:00:03,930 We're going to build up our first workflow. 4 00:00:04,200 --> 00:00:07,530 It's going to make sure that we build an image for the service, push the Docker hub. 5 00:00:07,620 --> 00:00:10,680 All that stuff back over on my GitHub repo. 6 00:00:11,400 --> 00:00:12,950 I'm gonna find the actions tab. 7 00:00:13,960 --> 00:00:15,940 And I'm going to make a new workflow. 8 00:00:18,320 --> 00:00:23,020 Once here, I can either click on set up these simple workflow or I can take any other again. 9 00:00:23,120 --> 00:00:26,540 It doesn't matter because we're going to delete everything and build it back up from scratch. 10 00:00:27,410 --> 00:00:31,610 You can click on any of the setup workflow buttons to this window. 11 00:00:32,000 --> 00:00:36,170 We're gonna delete all the code inside there and we'll also rename the file itself. 12 00:00:36,950 --> 00:00:41,720 So we're going to use nomenclature here of the ploy and then the name of the service. 13 00:00:42,380 --> 00:00:46,130 The first service that we're going to try to work on deployment for is the OK service. 14 00:00:46,130 --> 00:00:51,350 Of course, you're going to call this new file deploy dash off dot Yamal. 15 00:00:53,310 --> 00:00:55,210 That inside of here, we're going to put together our config. 16 00:00:55,270 --> 00:01:00,010 That's going to dictate when we run this workflow and exactly what it's going to do. 17 00:01:02,030 --> 00:01:06,790 I to first put in the name property, which will be deploy dash off. 18 00:01:08,870 --> 00:01:12,050 Well, then put an on to dictate when this thing should be executed. 19 00:01:12,800 --> 00:01:16,520 So we want to run this thing and this is going to be a little bit not quite makes sense, but we're 20 00:01:16,520 --> 00:01:18,920 going to run this whenever there is a push. 21 00:01:20,220 --> 00:01:21,120 On a branch. 22 00:01:22,320 --> 00:01:24,060 Of Dash Master. 23 00:01:25,480 --> 00:01:29,300 And we're also going to setup a filter here to say that we only want to run this when something inside 24 00:01:29,330 --> 00:01:32,230 of the author directory changes go under. 25 00:01:32,270 --> 00:01:37,250 Push on the same level of indentation as branches begin to put in parts. 26 00:01:38,030 --> 00:01:42,410 And then a dash and off flash star star like so. 27 00:01:43,380 --> 00:01:45,610 You might be curious, why are we putting pushier? 28 00:01:46,260 --> 00:01:52,230 Well, whenever we close or merge a pull request, that actually counts as a push directly to the master 29 00:01:52,230 --> 00:01:52,740 branch. 30 00:01:53,490 --> 00:01:58,710 So this little check right here is going to run this workflow whenever we merge a pull request into 31 00:01:58,710 --> 00:01:59,610 the master branch. 32 00:02:00,330 --> 00:02:05,550 It's also only going to run if it contains a change to something inside of that off directory. 33 00:02:08,310 --> 00:02:09,210 All right, so after that. 34 00:02:10,660 --> 00:02:14,280 We can go back to the top level of indentation if this editor will cooperate with me. 35 00:02:14,310 --> 00:02:14,760 There we go. 36 00:02:15,450 --> 00:02:16,760 We'll enter in jobs. 37 00:02:17,590 --> 00:02:18,990 We're going to provide a job I.D.. 38 00:02:19,020 --> 00:02:20,310 So this is just the name of the job. 39 00:02:20,530 --> 00:02:21,480 Look in use build. 40 00:02:21,660 --> 00:02:23,160 I'm not super picky on this build. 41 00:02:23,190 --> 00:02:26,280 Technically, on our test workflow was not most ideal. 42 00:02:26,280 --> 00:02:29,130 We probably should call it test, but it's not a big difference. 43 00:02:30,340 --> 00:02:31,380 We're going to enter in here. 44 00:02:31,410 --> 00:02:34,080 Let me zoom in just a little bit further to make sure this is super legible. 45 00:02:34,140 --> 00:02:38,580 We're going to enter in runs on the wound to latest. 46 00:02:40,700 --> 00:02:42,530 And then we'll define a series of steps. 47 00:02:43,070 --> 00:02:47,330 The first step we want to run here is check out all of our code inside of our repo. 48 00:02:47,750 --> 00:02:49,100 Before that, we're going to say uses. 49 00:02:50,210 --> 00:02:53,180 Actions slash checkout at BE2. 50 00:02:57,480 --> 00:03:01,860 After that, I'm going to put in another dash and we're going to run a command right here. 51 00:03:02,550 --> 00:03:06,130 The command we're going to run is essentially going to go through this process. 52 00:03:06,150 --> 00:03:08,910 We're going to build out our image and then push it off to Docker Hub. 53 00:03:10,470 --> 00:03:15,540 Whenever we make use of this Lubutu latest operating system, as can the base, really, it is again 54 00:03:15,540 --> 00:03:16,080 a container. 55 00:03:16,080 --> 00:03:19,110 So it's technically an image as opposed to anything else. 56 00:03:19,470 --> 00:03:21,080 It comes with docker or preinstalled. 57 00:03:21,370 --> 00:03:22,880 You can make use of all the docker commands. 58 00:03:22,890 --> 00:03:25,020 We are already familiar with the for example. 59 00:03:25,050 --> 00:03:36,450 We will do a change in 2D auth directory and do a docker build dashty your docker I.D. slash off dot. 60 00:03:37,590 --> 00:03:40,400 And technically, we don't have to change into the off directory. 61 00:03:40,430 --> 00:03:45,440 We actually can run the docker, build command and then say, oh yeah, just go into the author folder. 62 00:03:45,470 --> 00:03:47,480 So instead of DOT right there, we can put it off. 63 00:03:47,930 --> 00:03:50,360 But personally, I'd kind of like just changing into the folder. 64 00:03:50,420 --> 00:03:51,950 It just leaves the docker build command. 65 00:03:51,980 --> 00:03:53,390 Very easy and simple to read. 66 00:03:55,980 --> 00:03:59,470 After we build the image, we're then going to take the image and push it off to Docker Hub. 67 00:04:00,000 --> 00:04:01,830 Remember to push an image to Docker Hub. 68 00:04:01,890 --> 00:04:04,640 We must be logged in to the doctor, see a lie. 69 00:04:05,070 --> 00:04:05,790 The doctor see a lie. 70 00:04:05,880 --> 00:04:08,970 Must know who you are, what your doctor account is. 71 00:04:09,480 --> 00:04:13,550 So before we can push it off to Docker Hub, we have to log in to the Doctor Seelye. 72 00:04:13,690 --> 00:04:18,810 I remember this entire script right here is not being executed on your machine is being ran inside of 73 00:04:18,810 --> 00:04:20,820 some container managed by GetUp. 74 00:04:22,010 --> 00:04:26,600 So we have to somehow tell Docker to log in using it, your username and password. 75 00:04:27,200 --> 00:04:31,220 Of course, we are not going to enter your Dacher username and password directly into the script. 76 00:04:31,730 --> 00:04:38,090 Instead, we're going to add your username and password as a secret into your GitHub repository itself. 77 00:04:39,080 --> 00:04:43,880 Once we add it in as an encrypted secret to your repository, we can then reference that in a secure 78 00:04:43,880 --> 00:04:45,410 fashion inside of the script. 79 00:04:45,770 --> 00:04:47,420 So let me show you how we're going to do that. 80 00:04:48,500 --> 00:04:53,090 At the top of the screen, on the right hand side, I'm going to find settings for this individual repository. 81 00:04:53,780 --> 00:04:55,190 I can open that inside a new tab. 82 00:04:57,660 --> 00:05:00,660 Then once you're on the left hand side, I'm going to scroll down and find secrets. 83 00:05:03,260 --> 00:05:04,580 Well, then add a new secret. 84 00:05:07,090 --> 00:05:12,290 And this is where we are going to individually add in the password and username for your Docker hub 85 00:05:12,350 --> 00:05:12,800 account. 86 00:05:13,310 --> 00:05:16,820 Now, once you add it in here, no one else is going to be able to easily see this information. 87 00:05:17,210 --> 00:05:18,600 So it is absolutely OK. 88 00:05:18,650 --> 00:05:23,600 And this is one hundred percent is where we would want to enter in some protected information like a 89 00:05:23,600 --> 00:05:24,050 password. 90 00:05:24,860 --> 00:05:29,990 So we're going to enter in a name of Docker underscore username. 91 00:05:30,950 --> 00:05:33,080 And we'll put our username right here in. 92 00:05:33,100 --> 00:05:36,400 As the value, so for me, my doctor username is Stephen Grider. 93 00:05:37,380 --> 00:05:38,910 I'm going to add that as a secret. 94 00:05:41,650 --> 00:05:47,170 And then going to add in a second secret or my password, the doctor underscore password. 95 00:05:48,090 --> 00:05:49,680 Now, just so you do not see my password. 96 00:05:49,740 --> 00:05:54,090 I'm not going to show or not going to enter in my password right now, but you can believe that after 97 00:05:54,090 --> 00:05:54,990 this video is over. 98 00:05:55,200 --> 00:05:57,990 I am going to enter my password here and click on Add Secret. 99 00:05:58,890 --> 00:06:04,140 After that, we will have access to our doctor username and password inside of our script. 100 00:06:05,320 --> 00:06:06,860 But here's the script we're just working on. 101 00:06:07,650 --> 00:06:10,300 So how do we use those secrets to actually log into Docker? 102 00:06:10,760 --> 00:06:15,680 Well, let me show you exactly how we're going to enter in a new dash statement here. 103 00:06:15,680 --> 00:06:16,910 We're going entering run. 104 00:06:18,170 --> 00:06:24,290 We're going to say Docker, log in, dash you dollar sign, Docker underscore username. 105 00:06:25,560 --> 00:06:29,460 And DSP dollar sign, Dacher underscore password. 106 00:06:31,350 --> 00:06:37,360 Now we are referencing Dockery's name and password as environment variables when we add in a secret 107 00:06:37,380 --> 00:06:39,310 to a repository, as we did just a moment ago. 108 00:06:39,670 --> 00:06:43,360 Those do not automatically get added into the script as enviroment variables. 109 00:06:43,390 --> 00:06:49,270 Instead, we have to tell GitHub that we want those two secrets to be added as specifically environment 110 00:06:49,270 --> 00:06:51,940 variable called Docker's name and Docker password. 111 00:06:52,600 --> 00:06:56,380 So to do so on the next line down without adding in an additional dash. 112 00:06:56,440 --> 00:06:57,740 So notice how there's no dash here. 113 00:06:58,220 --> 00:06:59,500 We can enter an EMV. 114 00:07:01,390 --> 00:07:07,120 And I'm going to say that I want to have an environment variable inside of my script called Docker Username. 115 00:07:08,440 --> 00:07:09,910 And I want that to come from. 116 00:07:10,920 --> 00:07:13,650 Dollar sign, really brace, curly brace. 117 00:07:14,590 --> 00:07:15,280 Secrets. 118 00:07:16,790 --> 00:07:17,300 Dot. 119 00:07:17,690 --> 00:07:18,290 Dr.. 120 00:07:20,130 --> 00:07:22,660 Username closing curly braces. 121 00:07:24,260 --> 00:07:26,870 And then I'm going to repeat the same thing for Dr Password. 122 00:07:29,440 --> 00:07:31,240 And dollar sign curly braces. 123 00:07:33,310 --> 00:07:36,480 Secrets that doctor password. 124 00:07:38,090 --> 00:07:43,190 Now, this kind of stuff right here is where I've found that people in courses a billion times over. 125 00:07:43,250 --> 00:07:44,750 Always tend to make typos. 126 00:07:44,780 --> 00:07:47,780 So I beg you, please double check your spelling. 127 00:07:47,900 --> 00:07:49,970 Double check the number of curly braces. 128 00:07:50,330 --> 00:07:53,510 Make sure you've got all capitals here except for on secrets, of course. 129 00:07:53,750 --> 00:07:57,920 This double check, this section, because I can guarantee you this is going to be a location where 130 00:07:57,920 --> 00:08:00,530 many people make a very subtle, small typo. 131 00:08:02,510 --> 00:08:05,740 So after you run the step, we should now be authenticated with Dr. 132 00:08:06,000 --> 00:08:08,850 And we can now push the image that we had just created in the last step. 133 00:08:10,580 --> 00:08:12,220 So we can then add in another. 134 00:08:14,050 --> 00:08:21,040 Dashed in here and we can run the command docker push and then my case will be Stephen Grider slash 135 00:08:21,100 --> 00:08:21,460 off. 136 00:08:23,990 --> 00:08:24,500 All right. 137 00:08:24,680 --> 00:08:27,920 So that should take us all the way through to this step right here. 138 00:08:28,320 --> 00:08:32,170 And I think that this would be a really good place to pause and then try to test all this stuff out 139 00:08:32,200 --> 00:08:36,010 the next video, just to make sure that we are able to build a new image and push it off. 140 00:08:36,960 --> 00:08:39,480 So let's take a pause right here and continue in just a moment.
