1 00:00:02,130 --> 00:00:04,620 Now even though this was a huge course 2 00:00:04,620 --> 00:00:07,240 and we covered all the important core concepts 3 00:00:07,240 --> 00:00:11,350 you gotta know there of course also are a couple of things 4 00:00:11,350 --> 00:00:14,240 which were not included in this course. 5 00:00:14,240 --> 00:00:17,890 A couple of areas you might wanna dive in next, 6 00:00:17,890 --> 00:00:20,203 if you're interested in these areas. 7 00:00:21,050 --> 00:00:23,730 For example of course we mostly 8 00:00:23,730 --> 00:00:27,890 use Node.js applications as examples. 9 00:00:27,890 --> 00:00:32,380 We also had some Python and PHP with Laravel even, 10 00:00:32,380 --> 00:00:34,680 but they're also our programming languages 11 00:00:34,680 --> 00:00:36,710 which were not covered at all. 12 00:00:36,710 --> 00:00:38,790 Of course because it's impossible 13 00:00:38,790 --> 00:00:40,830 to squeeze them all into one course 14 00:00:40,830 --> 00:00:44,010 and all that because it doesn't matter. 15 00:00:44,010 --> 00:00:47,330 Docker really works in the same way, 16 00:00:47,330 --> 00:00:51,620 no matter which application and which programming language 17 00:00:51,620 --> 00:00:54,520 you wanna use to gather with Docker. 18 00:00:54,520 --> 00:00:58,500 Of course how you configure your image may differ 19 00:00:58,500 --> 00:01:01,080 the steps you need to execute there 20 00:01:01,080 --> 00:01:03,770 in your Docker file to set up that image 21 00:01:03,770 --> 00:01:07,770 that might differ depending on the language you're using. 22 00:01:07,770 --> 00:01:09,850 But that is what you can look up 23 00:01:09,850 --> 00:01:13,130 if you wanna use stalker for something else. 24 00:01:13,130 --> 00:01:15,200 The core concepts and certain texts 25 00:01:15,200 --> 00:01:18,060 and commands that will always be the same. 26 00:01:18,060 --> 00:01:21,460 And that of course is what the course was about. 27 00:01:21,460 --> 00:01:24,980 It's just not possible to cover every single programming 28 00:01:24,980 --> 00:01:29,330 language and give you examples for every specific use case. 29 00:01:29,330 --> 00:01:33,070 I Robert give you the tools which you need to then dive into 30 00:01:33,070 --> 00:01:37,020 such examples and such use cases on your own. 31 00:01:37,020 --> 00:01:39,360 Now besides that this course 32 00:01:39,360 --> 00:01:42,890 also did not focus on continuous integration 33 00:01:42,890 --> 00:01:46,950 and continuous delivery CI/CD workflows. 34 00:01:46,950 --> 00:01:49,890 I showed you how to use stalker locally, 35 00:01:49,890 --> 00:01:52,290 I showed you multi-stage builds, 36 00:01:52,290 --> 00:01:56,450 I showed you how to deploy Docker containers manually or 37 00:01:56,450 --> 00:01:59,360 with a managed service or with Kubernetes. 38 00:01:59,360 --> 00:02:03,980 But we did not talk about complex CI/CD pipelines 39 00:02:03,980 --> 00:02:07,800 with external CI/CD tools like Travis, 40 00:02:07,800 --> 00:02:10,263 GitHub actions or AWS CodePipeline. 41 00:02:12,160 --> 00:02:15,840 And I did not talk about that for a reason 42 00:02:15,840 --> 00:02:20,440 because it's in its core not related to Docker. 43 00:02:20,440 --> 00:02:24,600 Yes you can use Docker in CI/CD pipelines. 44 00:02:24,600 --> 00:02:28,860 It's very popular to do that, but to do that, 45 00:02:28,860 --> 00:02:33,120 you need to learn how to work with that CI/CD service 46 00:02:33,120 --> 00:02:36,280 you wanna use not so much about Docker. 47 00:02:36,280 --> 00:02:38,800 You will still just use your Docker images 48 00:02:38,800 --> 00:02:41,710 and containers in such CI/CD pipelines. 49 00:02:41,710 --> 00:02:44,370 And therefore what you learned about that in this course 50 00:02:44,370 --> 00:02:47,360 will help you with CI/CD as well. 51 00:02:47,360 --> 00:02:51,140 I did not wanna focus on CI/CD in this course 52 00:02:51,140 --> 00:02:54,420 since there are thousands of providers 53 00:02:54,420 --> 00:02:56,480 and therefore what I teach you there 54 00:02:56,480 --> 00:02:59,480 would really not give you that much 55 00:02:59,480 --> 00:03:01,960 because the darker part your containers 56 00:03:01,960 --> 00:03:05,460 and images that works as learned it in the course. 57 00:03:05,460 --> 00:03:09,720 But how you then put and manage these containers with CI/CD 58 00:03:09,720 --> 00:03:14,370 providers like Trevis, that's very provider specific. 59 00:03:14,370 --> 00:03:18,140 Therefore you should rover dive into specific docs 60 00:03:18,140 --> 00:03:21,440 or blog posts or tutorials focusing on that 61 00:03:21,440 --> 00:03:25,100 if you wanna learn more about Docker with CI/CD 62 00:03:25,100 --> 00:03:26,933 with a specific provider. 63 00:03:27,920 --> 00:03:31,130 Now talking about specific providers of course 64 00:03:31,130 --> 00:03:35,310 this course did use AWS for deployment. 65 00:03:35,310 --> 00:03:39,070 This was one example and whilst the exact details 66 00:03:39,070 --> 00:03:41,877 of course will still only apply to AWS. 67 00:03:42,860 --> 00:03:45,640 The general concepts that will matter 68 00:03:45,640 --> 00:03:49,710 and that need to be managed will always apply no matter 69 00:03:49,710 --> 00:03:52,580 which hosting provider you wanna use. 70 00:03:52,580 --> 00:03:55,810 Still of course this course was about Docker 71 00:03:55,810 --> 00:03:57,810 and Kubernetes and therefore 72 00:03:57,810 --> 00:04:00,587 we only scratched the surface of AWS. 73 00:04:01,950 --> 00:04:05,410 We did not dive deeply into AWS 74 00:04:05,410 --> 00:04:09,090 all its services and not even into the services 75 00:04:09,090 --> 00:04:11,330 which we did use in this course. 76 00:04:11,330 --> 00:04:14,150 If you wanna do that you absolutely can. 77 00:04:14,150 --> 00:04:17,120 But then it's more of a AWS course. 78 00:04:17,120 --> 00:04:21,250 You're looking for less about Docker because again 79 00:04:21,250 --> 00:04:23,710 that really is the main theme of this course. 80 00:04:23,710 --> 00:04:27,530 I wanted to teach you Docker and how to work with it. 81 00:04:27,530 --> 00:04:30,920 And you learnt that in great detail. 82 00:04:30,920 --> 00:04:35,920 If you then wanna explore all the features offered by AWS 83 00:04:36,087 --> 00:04:39,440 ECS the official documentation of that service 84 00:04:39,440 --> 00:04:41,590 is the place to go since status 85 00:04:41,590 --> 00:04:45,580 where you can learn about all the specific features AWS 86 00:04:45,580 --> 00:04:49,740 offers you and how to use and configure these features. 87 00:04:49,740 --> 00:04:51,880 On a similar note we of course 88 00:04:51,880 --> 00:04:55,430 did not cover other cloud providers in this course 89 00:04:55,430 --> 00:04:58,860 because just as with the programming languages 90 00:04:58,860 --> 00:05:03,860 there are hundreds or at least dozens of cloud providers out 91 00:05:03,970 --> 00:05:05,690 there which you could use 92 00:05:05,690 --> 00:05:07,610 and you could fill entire courses 93 00:05:07,610 --> 00:05:10,130 on just one cloud provider. 94 00:05:10,130 --> 00:05:12,930 And therefore again my focus was 95 00:05:12,930 --> 00:05:16,520 to show you how Docker works and which core topics 96 00:05:16,520 --> 00:05:19,740 you should think about when you deploy Docker. 97 00:05:19,740 --> 00:05:21,060 But if you then for example 98 00:05:21,060 --> 00:05:24,170 wanna use Microsoft Azure or the Google Cloud 99 00:05:24,170 --> 00:05:27,250 or Digital Ocean or anything else. 100 00:05:27,250 --> 00:05:30,750 The official documentation of that cloud provider 101 00:05:30,750 --> 00:05:33,820 is the place to go just as with 102 00:05:33,820 --> 00:05:37,503 the AWS Deep Dives you might be interested in. 103 00:05:38,520 --> 00:05:42,280 And last but not least it's of course also worth mentioning 104 00:05:42,280 --> 00:05:45,900 that I focused on the developer side of Docker 105 00:05:45,900 --> 00:05:48,010 and working with Docker. 106 00:05:48,010 --> 00:05:52,780 This is no Advanced Cluster or Docker Administration course. 107 00:05:52,780 --> 00:05:57,780 I did not dive into advanced administration topics of your 108 00:05:58,150 --> 00:06:00,700 Kubernetes cluster off the machines 109 00:06:00,700 --> 00:06:03,310 your Docker containers run on. 110 00:06:03,310 --> 00:06:06,680 Because that really is something which is less related 111 00:06:06,680 --> 00:06:10,840 to Docker and more related to general server 112 00:06:10,840 --> 00:06:13,280 and machine administration. 113 00:06:13,280 --> 00:06:15,750 And that I have to be honest here 114 00:06:15,750 --> 00:06:17,580 is not what I'm an expert in. 115 00:06:17,580 --> 00:06:21,350 And that's typically not what you have to be an expert in. 116 00:06:21,350 --> 00:06:25,800 If you just wanna work with Docker as a developer. 117 00:06:25,800 --> 00:06:29,810 And that's really important this course was for developers. 118 00:06:29,810 --> 00:06:32,450 It's meant to help you use Docker 119 00:06:32,450 --> 00:06:36,610 and Kubernetes as possibly in your next projects. 120 00:06:36,610 --> 00:06:40,190 You will typically not be the one administrating the 121 00:06:40,190 --> 00:06:43,410 machines your application runs on. 122 00:06:43,410 --> 00:06:45,520 Instead you will be the one writing the code 123 00:06:45,520 --> 00:06:49,000 and Dockerizing the application to then deploy it 124 00:06:49,000 --> 00:06:52,640 onto a managed service or onto machines managed 125 00:06:52,640 --> 00:06:56,190 by someone else who is an expert administrator. 126 00:06:56,190 --> 00:06:58,510 So that's what was not in the course 127 00:06:58,510 --> 00:07:00,450 and why it was not in the course 128 00:07:00,450 --> 00:07:04,170 and how you can still proceed with these topics 129 00:07:04,170 --> 00:07:06,193 if you are interested in them.
