Lab 13. How to Create a vApp This lesson offers participants step by step instructions in a lab-based format in how to do the following:

  • Create a vApp

  • Power it up

  • Power it back down

  • Remove it

A vApp is very useful in that it allows you to group several VMs together so you can build a multi-tiered application and treat it as a single unit.

Video Transcription

Hello and welcome to lab number 13
00:07
in this lab will be working with V APS.
00:11
We'll get a creative E AP You'll you'll at some v EMS to it.
00:14
Powered up
00:16
power back down and then remove it.
00:20
Okay, so the V app is actually really useful.
00:24
A bit of technology allows you to group
00:26
several V EMS together
00:29
so that you can build a multitiered application
00:32
and then treated as a single unit,
00:35
which is pretty handy.
00:38
So let's get logged into our environment.
00:43
Looks like a fat finger. The password.
00:55
Here we go.
00:56
All right, so
00:58
it's very easy to create the VF.
01:03
We simply
01:04
go to our home inventory hosts and clusters screen,
01:11
and we can see that we've got all our v ems with our couple of our hosts.
01:15
But in order to create the aptly actually have to go to the PM's and templates screen. So we hold down control shift V
01:23
for a short cut.
01:26
What?
01:27
That takes us right to this screen.
01:30
Now, I already have the two v EMS power down.
01:36
They do need to be powered down when you create the V app. Just keep that in mind.
01:47
So what I can do is
01:49
click my Lab PM's folder.
01:53
This is where the PM's probably should live
01:56
action within their first.
02:04
Now I right click the folder and I can select new V app
02:07
and please think about using folders as much as possible just to keep everything organized.
02:13
It's much simpler to
02:15
give descriptive names to your V EMS in your folders and bill to find things later. You can always do a search in the inventory
02:23
up here in the corner,
02:25
but if your name everything and organize it well from the beginning, it just
02:29
it's a lot easier to deal with.
02:31
Okay, so we select new V app.
02:34
We'll give it a name like My
02:37
Pierre.
02:40
Then I'll pick the host.
02:43
I'll stick with that 100
02:46
we can pre allocate. Some resource is,
02:51
for instance, your CPU memory sources can be set thio several different ranges. We can have low
02:58
normal or high,
03:00
or you can specify an absolute number.
03:04
Using the reservations is a little bit more flexible on. We'll talk about that later.
03:09
Okay, we get to our finish screen
03:13
and we'll go ahead and click that
03:15
and you see the new style icon that gets created here. My V ep.
03:21
It's got an interesting little cluster of the EMS.
03:24
So what we'll do next is
03:27
actually dragged the V EMS
03:29
to the Viet.
03:43
Okay, so let's change our view to hosts and clusters, so I'll do a control shift. H
03:55
Here we go.
03:57
And now I can see that my V EP appears under the host, and I could expand it to see the V ems that are
04:03
part of the Viet.
04:05
Now let's look at our settings or right click
04:10
go down to at its settings
04:15
again, we can adjust. Our resource is for CPU and RAM
04:19
and also adjust to start order.
04:23
So this is a simple of Yep, with only two v EMS. But you could conceivably see how you could have multiple
04:29
V EMS. They're all part of an application, and you might want to start them
04:33
in a standard fashion. So you can pick two different groups
04:39
and you simply select of'em and move it around with the arrows.
04:42
And you could change the
04:46
the timing of the start up.
04:47
If that suits your purposes,
04:50
we're just gonna leave this the way it's It is set right now.
04:56
and we'll go ahead and click. Okay,
04:59
Now, the next task is to power the VF on
05:02
so we can select our right click and select power on.
05:06
And now both of those V ems.
05:10
Well, come up.
05:13
You can see that the bottom here, they're both powering up,
05:16
and they're pretty much pretty much ready to run.
05:19
Yeah,
05:21
so very simple, as you can see, to create the virtual app.
05:26
And it gives you a great logical
05:28
tool, too,
05:30
to structure of your applications and maker environment. More easy to manage.
05:42
Okay, so now we're going to shut down the Viet once it finishes powering all the way up. Since we don't actually need it, we just created it for demonstration purposes.
05:51
98%. We're almost there.
05:58
And if you recall,
06:00
I left the default settings for the amount of delay for starting up. The APS are starting up the VM. They're part of the app,
06:09
so
06:11
they both powered up at the same time. That's why we're waiting at the same moment.
06:14
Since they're they're the same exact VM.
06:16
However, if you had a database
06:19
ah, Web server and maybe an application server bundled together as a V app.
06:24
You might want to stagger that, you know, start the database server first.
06:28
It might take a long time to get going
06:30
and then bring up
06:31
the application server on the Web server later.
06:44
Okay, so the VF is fully powered on. We can see both of the virtual machines running.
06:49
Okay. And now I'd like to shut it out
06:51
selections, right. Click
06:54
and go to shut down.
06:58
Asks if I want to shut down the guest operating systems.
07:00
I'll just say yes,
07:03
you could be more graceful and shut down each individual
07:06
vm separately.
07:10
But since these air Lavey EMS, I'm not worried about it.
07:15
Okay, so now the V M v EPA shut down. I can right click
07:19
and delete from disk.
07:21
Oh, but don't do that too soon. You actually want to drag the VMS out,
07:27
drag them back to your host.
07:32
Otherwise you might delete the PM's. You don't want that. So now we can delete the V app from desk.
07:43
Okay. The last task that we have to do, which is a good idea when you work with the APS,
07:47
is to reboot the
07:50
the V Center server appliance.
07:54
So I'm going to open a Web browser
08:01
and we'll go to our
08:05
Web client.
08:18
He's taking a moment.
08:26
Here we go.
08:31
The Web client does have some initialization time
08:33
compared to using the vic, so keep that in mind.
08:54
Okay, so our last task
08:56
is to get connected to the appliance
09:01
and reboot it.
09:01
It's a good idea when you're working with the APS,
09:05
especially if they've been running for a while to occasionally reboot your server appliance.
09:09
Because there are problems like I created somewhat from
09:13
time drift.
09:16
NTP obviously keeps that situation under control, but
09:22
we haven't really logged into the
09:24
server appliance interface very much so. Let's have a look at that.
09:30
Will run Internet explore
09:39
and I'm going to the court. 9443 is for the Web client.
09:43
Like,
09:43
for
09:45
the administrative client, it's actually 54 80.
09:52
So we'll go ahead and accept
09:54
certificate
10:03
a little bit bigger.
10:11
So all our service is air running. Everything looks good, but we're just gonna go ahead and reboot anyway.
10:16
So go the system tab
10:18
and you have a reboot button here,
10:26
and that concludes lab number 13. So
10:31
lab 14
10:33
Well, actually, start working with some of our access controls
10:37
so that we can manage user permissions on R V EMS
10:41
and allows certain things and disallow others.
10:45
All right, Thank you. See you in lab 14.
