Hello and welcome to this lecture on TLS Certificates in Kubernetes. Securing the cluster with TLS and troubleshooting



2

00:00:08,250 --> 00:00:15,870

TLS related issues can be especially difficult if you are not familiar  with the basics of TLS certificates



3

00:00:16,920 --> 00:00:22,650

We sent out a Poll during the creation of this course about your knowledge on TLS Certificates.



4

00:00:22,650 --> 00:00:28,230

Most of you got back to us saying you had no clue about it or were not very comfortable with it.



5

00:00:28,530 --> 00:00:34,410

So we decided to put together a set of lectures that will help you gain enough knowledge to work with



6

00:00:34,410 --> 00:00:42,330

certificates in kubernetes. And of course these lectures will help you otherwise as well. If you are comfortable



7

00:00:42,330 --> 00:00:47,940

with this concept, feel free to skip the pre-requisite lectures and head straight over to the



8

00:00:47,940 --> 00:00:49,590

ones relevant to kubernetes.



9

00:00:50,950 --> 00:00:56,470

By the end of this section you should be an expert when it comes to working with certificates in general



10

00:00:56,590 --> 00:00:58,220

as well as with kubernetes.



11

00:00:58,360 --> 00:01:03,910

You should be able to easily configure and troubleshoot issues related to certificates. And the only



12

00:01:03,910 --> 00:01:10,690

way to do it, as I understand, is to learn and understand how it works in and out. And that’s what we are



13

00:01:10,690 --> 00:01:13,130

going to do in this section.



14

00:01:13,220 --> 00:01:16,530

We will start with the basics of certificates in general.



15

00:01:16,760 --> 00:01:21,620

If you are already comfortable with certificates, certificate authorities and how they work



16

00:01:21,620 --> 00:01:27,320

feel free to skip this lecture and go over to the next where we discuss this in the kubernetes terms.
