1 00:00:05,950 --> 00:00:11,720 Hello and welcome to the certified cabinet administrators course, my name is Moonshot, my number, 2 00:00:11,860 --> 00:00:14,040 and I will be your instructor for this course. 3 00:00:14,590 --> 00:00:16,780 So about me, I'm a solutions architect. 4 00:00:16,780 --> 00:00:20,440 I specialize on cloud automation and develops technologies. 5 00:00:20,990 --> 00:00:27,520 I have other several bestseller and top rated courses on technologies like Dr. Coburn and is an open 6 00:00:27,520 --> 00:00:31,960 shift, as well as automation technologies like Ansible, Chef and Puppet. 7 00:00:32,860 --> 00:00:38,950 This course is the third installment in the series on communities and focuses on the administrators 8 00:00:38,950 --> 00:00:39,790 certification. 9 00:00:40,460 --> 00:00:42,640 Let's take a look at the structure of this course. 10 00:00:43,240 --> 00:00:49,300 We start with a series of lectures on various topics in coroneted, where we simplify complex concepts 11 00:00:49,540 --> 00:00:53,290 using illustration, animation and some fun analogies. 12 00:00:53,860 --> 00:00:56,530 We have optional quizzes that test your knowledge. 13 00:00:56,530 --> 00:01:02,500 After each lecture, we have hundreds of practice questions that will help you practice what you learned 14 00:01:02,500 --> 00:01:05,800 on a real live environment right in your browser. 15 00:01:06,280 --> 00:01:08,890 Yes, you don't need to have your own environment. 16 00:01:08,890 --> 00:01:14,950 We give you the required labs that are real and that can be accessed by you anywhere, any time and 17 00:01:14,950 --> 00:01:16,270 as many times as you want. 18 00:01:17,120 --> 00:01:19,240 That is, certification is hands on. 19 00:01:19,480 --> 00:01:24,610 So the practice test will give you enough experience and practice on getting ready for it. 20 00:01:24,970 --> 00:01:26,350 More on this coming soon. 21 00:01:27,730 --> 00:01:33,910 We also have a dedicated channel that you had exclusive access to were experts and other students gather 22 00:01:33,910 --> 00:01:38,170 to help you clear your doubts and get instant support on your queries. 23 00:01:38,770 --> 00:01:43,210 We will also discuss some tips and tricks throughout this course to help you crack the certification 24 00:01:43,210 --> 00:01:43,630 exam. 25 00:01:44,020 --> 00:01:49,900 And as always, if you have any questions, you will reach out directly to us through our Q&A section 26 00:01:49,900 --> 00:01:51,010 or to select channel. 27 00:01:51,950 --> 00:01:58,040 Now, this is one of the course in the series on Cabernets and focuses on getting the community's administrators 28 00:01:58,040 --> 00:02:04,100 certification, so having a basic understanding to some of the concepts and prerequisites will help 29 00:02:04,850 --> 00:02:10,910 knowing basics of soccer and some basics of clarinettist itself, such as parts, deployments and services, 30 00:02:11,210 --> 00:02:14,270 and having a good understanding of the Yamal language. 31 00:02:14,540 --> 00:02:19,200 Setting up a basic lab environment using morschel books can all help in the journey. 32 00:02:19,790 --> 00:02:26,240 We do discuss setting up a carbon atoms cluster in detail in this course, and we also have online labs 33 00:02:26,240 --> 00:02:29,090 and practice tests for a lot of these concepts. 34 00:02:29,090 --> 00:02:35,720 But if you're an absolute beginner, I highly recommend taking the carbon atoms for the absolute beginners 35 00:02:35,720 --> 00:02:41,330 course first, which is a short, quick introduction to some of the basic concepts. 36 00:02:42,560 --> 00:02:44,330 Now look at the course objectives. 37 00:02:44,720 --> 00:02:50,780 The objectives of this course are aligned to match the certified carbon that is administrators exam 38 00:02:50,840 --> 00:02:51,410 curriculum. 39 00:02:51,940 --> 00:02:57,770 We will discuss about details around the certification itself in one of the upcoming lectures before 40 00:02:57,770 --> 00:02:59,600 heading into any of these topics. 41 00:02:59,630 --> 00:03:04,700 However, remember, this is not just a course to clear the certification. 42 00:03:05,000 --> 00:03:07,810 We discuss a number of other related topics. 43 00:03:07,820 --> 00:03:14,330 And the intent of this course is to get you to be good at installing, configuring and troubleshooting 44 00:03:14,340 --> 00:03:17,690 equipment that is cluster with the where the candidates are organized. 45 00:03:17,690 --> 00:03:21,750 In this course, we do not start the course by building a cluster from scratch. 46 00:03:21,800 --> 00:03:24,500 We actually do that towards the end of the course. 47 00:03:24,500 --> 00:03:27,050 In the installation configuration and validation section. 48 00:03:27,560 --> 00:03:33,140 You will be working on pre-built live clusters throughout the earlier sections in this course, and 49 00:03:33,140 --> 00:03:34,370 I think that makes sense. 50 00:03:35,060 --> 00:03:37,850 Think of this as learning to engineer and build a car. 51 00:03:38,210 --> 00:03:44,120 It would be much easier if you have already driven a car, know how it works, what the wheels are for, 52 00:03:44,420 --> 00:03:49,910 what the transmission is for, what the brakes are for and how to fill fuel, etc. That way you would 53 00:03:49,910 --> 00:03:53,690 be able to relate those to the underlying concepts better when you learn them. 54 00:03:54,020 --> 00:03:59,690 And that is why I think practicing on pre-built clusters and learning the basic concepts first will 55 00:03:59,690 --> 00:04:02,800 help you understand how to build a cluster from scratch. 56 00:04:03,020 --> 00:04:04,400 Towards the end of this course. 57 00:04:04,880 --> 00:04:11,150 We start with the core concepts where we look at the various components that form the cognitive architecture. 58 00:04:11,570 --> 00:04:15,560 We then discuss some of the API primitives here. 59 00:04:15,560 --> 00:04:22,070 We mostly recap what we learned in the beginners course about part replica sets, deployment's, name 60 00:04:22,070 --> 00:04:23,180 spaces, etc.. 61 00:04:23,870 --> 00:04:27,770 We then look at services and other network primitives. 62 00:04:27,770 --> 00:04:30,530 In the next section we look at scheduling. 63 00:04:30,560 --> 00:04:37,250 We start with labels and selectors, followed by deman sets and how resource limits can affect pod placements. 64 00:04:37,670 --> 00:04:43,010 We look at ways of manually scheduling apart and configuring multiple schedulers and how to view the 65 00:04:43,010 --> 00:04:46,430 scheduler events in the logging and monitoring section. 66 00:04:46,430 --> 00:04:52,580 We look at different ways of monitoring and logging the cluster of components, as well as applications 67 00:04:52,580 --> 00:04:56,710 hosted on the Cluster and the Application Lifecycle Management Section. 68 00:04:56,730 --> 00:05:02,570 We look at rolling updates and rollbacks and various ways of configuring applications, scaling applications 69 00:05:02,570 --> 00:05:06,890 and the primitives necessary to create a self healing application. 70 00:05:07,310 --> 00:05:12,230 In the cluster maintenance section, we look at the different options available to take down a node 71 00:05:12,230 --> 00:05:14,420 in the cluster for maintenance purposes. 72 00:05:14,720 --> 00:05:20,930 We then look at how software releases are organized and that is followed by the cluster upgrade process. 73 00:05:21,410 --> 00:05:27,710 We will perform an upgrade to a live cluster yourself in the practice test without taking down the application. 74 00:05:27,950 --> 00:05:31,520 And finally we look at the different backup and restore methodologies. 75 00:05:32,150 --> 00:05:33,950 We then move to security. 76 00:05:34,550 --> 00:05:39,230 We start by looking at different ways of authenticating into the cluster. 77 00:05:39,500 --> 00:05:41,870 We take good look at certificates. 78 00:05:42,170 --> 00:05:48,110 We start all the way from the absolute basics of tearless certificates into how exactly a cluster can 79 00:05:48,110 --> 00:05:49,430 be secured with these. 80 00:05:49,790 --> 00:05:52,340 So there are many practice exercises around that. 81 00:05:52,700 --> 00:05:57,500 You will be asked to troubleshoot and fix issues related to certificates, which I believe will give 82 00:05:57,500 --> 00:05:59,750 you confidence in working with certificates. 83 00:06:00,290 --> 00:06:06,410 You look at the new certificates API, we then look at role based access controls and attribute based 84 00:06:06,410 --> 00:06:08,330 access controls for authorization. 85 00:06:08,600 --> 00:06:13,160 We then look at network policies and security context in the networking section. 86 00:06:13,160 --> 00:06:16,520 We start with some optional networking prerequisite lectures. 87 00:06:16,850 --> 00:06:21,530 This will help you understand and troubleshoot networking and capabilities in depth. 88 00:06:21,950 --> 00:06:28,580 So we start by understanding the basics of networking in Linux, basics of switching and routing and 89 00:06:28,580 --> 00:06:29,420 birth networks. 90 00:06:29,420 --> 00:06:34,430 In a Linux system, we try and understand the basics of TMS, what core DNS is. 91 00:06:34,640 --> 00:06:39,950 We then look at network names, faces and then relate those concepts to networking in Docker. 92 00:06:40,070 --> 00:06:42,680 We then start with networking in a Cuban cluster. 93 00:06:42,680 --> 00:06:44,480 We look at CNI and what they are. 94 00:06:44,510 --> 00:06:48,050 We look at one of the nine networks in depth and how it functions. 95 00:06:48,380 --> 00:06:51,050 We look at how service networking works under the hood. 96 00:06:51,630 --> 00:06:57,440 Then look at DNS and clarinettist cluster and finally increase networking, and of course, the section 97 00:06:57,440 --> 00:07:03,050 is filled with practice exercises where you will practice viewing and gathering networking information 98 00:07:03,260 --> 00:07:08,540 from a cluster, implementing network configurations and troubleshooting network related issues in a 99 00:07:08,540 --> 00:07:08,960 cluster. 100 00:07:09,110 --> 00:07:14,200 We then look at designing, installing, configuring and validating equipment at his cluster from scratch. 101 00:07:15,220 --> 00:07:21,130 We understand how a high availability cluster works and how and it could cluster works and the best 102 00:07:21,130 --> 00:07:27,940 practices in deploying and cluster, you look at two ways of bootstrapping a worker, not one the usual 103 00:07:27,940 --> 00:07:31,390 way and the other using the bootstrap approach. 104 00:07:31,960 --> 00:07:37,210 We finally perform End-To-End tests on the cluster we deployed using the cornetist testing infrastructure. 105 00:07:37,660 --> 00:07:42,940 With all of this, you should have gained enough knowledge on how the various components work together 106 00:07:42,940 --> 00:07:44,130 in this cluster. 107 00:07:44,470 --> 00:07:46,800 So troubleshooting piece should come to you. 108 00:07:46,840 --> 00:07:53,920 Naturally, we look at some techniques that can be followed while troubleshooting a cluster and applications 109 00:07:53,920 --> 00:07:54,880 running on them. 110 00:07:55,130 --> 00:08:01,960 Again, we have a number of practice tests where we give you a broken cluster and you troubleshoot and 111 00:08:01,960 --> 00:08:04,000 fix them, but that's a lot. 112 00:08:04,000 --> 00:08:07,870 And we plan to add more relevant topics to this list going forward. 113 00:08:08,620 --> 00:08:11,260 Finally, a word about practice tests. 114 00:08:11,800 --> 00:08:18,220 The coroneted certification exam is a practical hands on exam, so it is very important to practice 115 00:08:18,220 --> 00:08:24,610 what you learn, which is why we have got a custom solution that will give you access to a real coronets 116 00:08:24,610 --> 00:08:30,670 environment right in your browser, along with a quiz portal that provides fun and challenging problems 117 00:08:30,670 --> 00:08:37,090 for you to solve, you're required to gain a set of different skills working with communities such as 118 00:08:37,090 --> 00:08:41,040 how to look for information, how to troubleshoot issues. 119 00:08:41,410 --> 00:08:46,000 That is why we have questions where you will be asked to find information within an environment. 120 00:08:46,420 --> 00:08:52,210 You will also be asked to perform configuration tasks where you will be required to configure and deploy 121 00:08:52,210 --> 00:08:54,730 applications and services on the cluster. 122 00:08:55,210 --> 00:08:58,090 We will test your work and provide feedback instantly. 123 00:08:58,780 --> 00:09:03,820 People occasionally make changes to the environment or break stuff and ask you to troubleshoot and fix 124 00:09:03,820 --> 00:09:04,060 them. 125 00:09:04,660 --> 00:09:10,480 These are common issues that one would face while working with communities, and these exercises will 126 00:09:10,480 --> 00:09:13,330 help you troubleshoot and fix issues quickly. 127 00:09:13,900 --> 00:09:18,520 When you see an error message, you should be able to understand what that means and where to look for 128 00:09:18,520 --> 00:09:21,590 information related to that error message and how to fix it. 129 00:09:22,090 --> 00:09:28,120 One of the major challenges in a practical test, like the one in the coroneted certification, is time. 130 00:09:28,360 --> 00:09:34,390 Even simple issues like a typo or an indentation error in a Yemen file can take a beginner hours to 131 00:09:34,390 --> 00:09:34,790 fix. 132 00:09:35,290 --> 00:09:41,170 This is why we have hundreds of such exercises in this course that will make you an expert and give 133 00:09:41,170 --> 00:09:44,030 you enough practice to help you clear the exam. 134 00:09:44,620 --> 00:09:46,180 Well, let's hope for now. 135 00:09:46,600 --> 00:09:49,210 Thank you for enrolling and I'll see you in class.
