1

00:00:00,180 --> 00:00:06,150

This is the solution video for the replica sets lab, so the first question we have to find out the



2

00:00:06,150 --> 00:00:08,790

number of parts that are running on the system.



3

00:00:10,080 --> 00:00:16,320

So let's go to the DOMHNALL and run the command cubicle and get Pod's answer a zero.



4

00:00:19,460 --> 00:00:27,010

How many replica sets exists on the system, so again, let's on the command kubek to get our yes or



5

00:00:27,020 --> 00:00:30,470

replica sets and again, the answer is zero.



6

00:00:33,670 --> 00:00:39,760

About know how many replica sets do you see, so let's run that command again and can see that there



7

00:00:39,760 --> 00:00:45,370

is one new replica set by the name of new dash replica dash set, which has been created.



8

00:00:47,660 --> 00:00:48,620

The answer is one.



9

00:00:50,070 --> 00:00:55,160

How many pods are designed and the new replica set so we can get this answer from the previous command,



10

00:00:56,040 --> 00:00:57,510

so the answer is for.



11

00:00:58,730 --> 00:01:00,020

For design parts.



12

00:01:03,000 --> 00:01:09,430

What is the image used to create the possibly replica set, so to find this will run kill, describe



13

00:01:09,430 --> 00:01:12,480

a replica set and the name of the replica said.



14

00:01:13,280 --> 00:01:18,020

And if you scroll up, we'll be able to see the image which is busy, box seven seven seven.



15

00:01:21,040 --> 00:01:23,500

How many pods are in real estate?



16

00:01:23,890 --> 00:01:26,560

So, again, we can make use of the command from before.



17

00:01:28,960 --> 00:01:31,270

I can see that zero parts are running.



18

00:01:33,500 --> 00:01:37,250

All of four desired, so the answer is zero.



19

00:01:41,320 --> 00:01:48,490

Why do you think the pods are not ready so we can see the reason from the even S. the image that is



20

00:01:48,490 --> 00:01:50,420

used as Basbug 777.



21

00:01:50,440 --> 00:01:54,460

So let's run Kubek to you get pods.



22

00:01:55,210 --> 00:01:58,030

All of them are an air imitable status.



23

00:01:58,030 --> 00:01:59,950

So let's describe one of these pods.



24

00:02:02,150 --> 00:02:08,870

And from the even section, we can see that it's unable to pull a pulled US docker image because the



25

00:02:08,870 --> 00:02:13,760

repository may not exist, so there is no image by this name in Docker Hub.



26

00:02:14,990 --> 00:02:16,400

So that secret answer.



27

00:02:17,790 --> 00:02:20,100

Now, let's try to delete one of the four pods.



28

00:02:21,860 --> 00:02:29,270

So we'll do this by running cubicle delete pod and you can pick any pod from the four.



29

00:02:30,820 --> 00:02:32,350

Wait for the report to be deleted.



30

00:02:36,690 --> 00:02:43,620

How many pods exist now, so let's run CubeSat, we'll get pods and you'll see that there are four pods



31

00:02:43,620 --> 00:02:44,420

still running.



32

00:02:44,460 --> 00:02:47,010

One of them was one up 12 seconds ago.



33

00:02:50,040 --> 00:02:50,970

And as for.



34

00:02:52,360 --> 00:02:55,700

Why are there still four parts even after you deleted one?



35

00:02:55,720 --> 00:02:57,890

So this is the feature of replicas.



36

00:02:58,020 --> 00:03:02,470

It always tries to make sure that it's running the desired number of ports.



37

00:03:02,860 --> 00:03:09,880

If a port is lost or deleted, it will automatically created to match the desired number of ports.



38

00:03:10,210 --> 00:03:11,470

So that's the correct answer.



39

00:03:13,140 --> 00:03:19,230

Now create a replica set using a definition file, which is located on the route called replica set



40

00:03:19,530 --> 00:03:23,820

definition dash one dot and it appears there's an issue with that.



41

00:03:23,830 --> 00:03:24,930

So we'll have to fix it.



42

00:03:28,710 --> 00:03:34,750

So first, let's try to apply or create that replica set from the definition.



43

00:03:35,430 --> 00:03:40,250

And here we are able to see an error that no matches for kind replica set and version be one.



44

00:03:40,740 --> 00:03:45,370

So if you follow the lecture, you will see that that was an AP version as incorrect.



45

00:03:45,780 --> 00:03:48,750

It should be forward slash we want instead of V1.



46

00:03:48,750 --> 00:03:52,140

So let's make a change to the definition file.



47

00:03:55,020 --> 00:04:02,100

So you're changing the value from we want to ABSs, we want and we'll save this file.



48

00:04:03,250 --> 00:04:09,220

The rest of the replica said definition was great, so once we applied again, we have been able to



49

00:04:09,220 --> 00:04:10,780

create the replica said.



50

00:04:16,770 --> 00:04:22,260

All right, moving along, we have another definition file called replica set dash definition, dash



51

00:04:22,260 --> 00:04:23,150

to document.



52

00:04:23,490 --> 00:04:25,470

And it appears there's an issue with that as well.



53

00:04:25,500 --> 00:04:26,340

So we have to fix.



54

00:04:31,380 --> 00:04:41,430

So let's open up that file and be editor, and if you look at the specs under the magic labels, we're



55

00:04:41,430 --> 00:04:45,300

using the tier as equal to front end, but under-report the report template.



56

00:04:45,300 --> 00:04:48,150

You'll notice that the label use just here is equal to engineers.



57

00:04:48,150 --> 00:04:50,070

So that's the problem with those definition file.



58

00:04:50,490 --> 00:04:55,530

Let's change the labels for the pod from Engine X to front end.



59

00:04:55,710 --> 00:05:02,850

And now let's try to create this object using cube steel applied ISAF and the replica set definition



60

00:05:02,850 --> 00:05:05,820

file and it has created the replica said.



61

00:05:08,760 --> 00:05:14,100

So now we have three in total and the latest one we created is a replica set dash to.



62

00:05:18,890 --> 00:05:26,480

So now let's delete the two newly created replica sets and four that will use Kubek to delete replicas



63

00:05:26,480 --> 00:05:28,760

set and the name of the replica said.



64

00:05:29,270 --> 00:05:32,930

So that's a replica set out a dash one and replicas a dash to.



65

00:05:33,710 --> 00:05:35,570

Now we just have one replica set.



66

00:05:35,570 --> 00:05:36,840

So that should be it.



67

00:05:39,650 --> 00:05:46,580

Now we have to fix the original replica set called New Dash Replica are set to use the correct image,



68

00:05:46,580 --> 00:05:47,440

which is possible.



69

00:05:53,680 --> 00:06:00,070

So we can delete and recreate if needed, so we are going to use the cube, ctrl edit replicas that



70

00:06:00,070 --> 00:06:07,900

come on and the name of the replica set and let's go all the way to the bottom and change the image



71

00:06:08,380 --> 00:06:13,690

from the Xbox 777 to the Xbox.



72

00:06:16,260 --> 00:06:23,220

Once that is done, we will save an exit and let's get the pods again and we'll have to delete all of



73

00:06:23,220 --> 00:06:27,870

these pods one by one for it to create a new board with the correct image.



74

00:06:28,380 --> 00:06:30,570

So let's delete all of these four pods.



75

00:06:43,460 --> 00:06:46,150

Not right now, so all four reports have been deleted.



76

00:06:46,160 --> 00:06:48,910

If Iran could still get pods again.



77

00:06:50,710 --> 00:06:54,850

We'll see that for new have been created and they are all in the running state.



78

00:06:57,120 --> 00:07:04,170

Now, let's clear up, like I said, do five pods to do this, we can run cube kill scale replica,



79

00:07:04,170 --> 00:07:09,060

set the name of the replica set and the replica is equal to five.



80

00:07:09,890 --> 00:07:15,690

If you're on it, you'll get what you can see, that a new pod has been created to match the desired



81

00:07:15,700 --> 00:07:20,520

number of pods, which is why now let us scale it down to two so we'll use the same command as before.



82

00:07:22,640 --> 00:07:25,340

But the Republicans this time will be to.



83

00:07:27,970 --> 00:07:33,110

Now, if you're on Kubasik, you'll get possibilty that three of the pods are in a dominating seat and



84

00:07:33,130 --> 00:07:37,410

I'll leave just two pots running in this replicative, which is what we desire.



85

00:07:39,720 --> 00:07:42,210

So that's the end of the slab.



86

00:07:42,240 --> 00:07:43,380

Thank you for joining me.



87

00:07:43,410 --> 00:07:44,790

I'll see you in the next one.
