Welcome, guys.
I hope you have learned some basics about DOCA in the previous section.
So if not, I would recommend you to go through them.
And if you have already known basics about doctor, you can actually start going through this lecture.
All right.
So now why, Doctor?
We want to bring into a picture here.
First, let's try to understand that.
So let's say you have both a Tomcat sort of in this lame X, B, and then you can deploy this lot file
into that so that you can see your application on browser, which we have seen in the beginning in Windows
section.
Right.
But problem here is tomorrow, if you have another application, another court, which you want to post
in this Lennix B, and if that application is expecting Yanov, that don't get washin.
So right now, that arm gets out of the question, is supporting Java eight.
OK.
So you have developed some application which runs on Java 13.
Then you'll have to deploy that application in to town, gets sort over which supports the Java Party.
So that Watson, the server, which is already Deery and Lere, may not support that question.
So you have to have another don't get server, which supports lesson number 13.
But insert in one system, you cannot have multiple tomcats out of us.
Right?
Ideally, you will have only one server and your host all you want files into that side of it just because
you have multiple applications.
You cannot have multiple Tomcat subtleties.
Similarly, if you have any legacy application, which is and have go big.
If that application is done on Java seven.
OK.
Then the current tomcats that what we are using will not help because that is minimum Java eight is
that requirement.
Right.
So this is just an example, fussin compatibilities is the headache we would have all the time whenever
people obtained a soft Timothe and that a lot of things comes into picture.
So right now, I'm talking about only one Frontin Hesterman.
But tomorrow that is one database.
You want to connect to some secret database and that database supports some 11. one version which you
have developed called.
But Linda.
If you want to upgrade your application and bring new application into this somewhat and that time sequel,
what some you might use a 40.
OK, so that time, if you are a, in your words, lame ex, previous application will break because
there is one legacy application which is using sequel one, Dark One and Tomcats sort of at seven.
If you bring new obligation, I would support a sequel 14.
So either if you start upgrading the sequence, I would just because to what you a new application or
an application will break.
Because that may not support this version.
So basically, to get rid of all this problems, you can have virtualization.
So that means in your operating system, only you can have like a new oil as a new operating system
on your main operating system.
But again, when I say New Orleans, it's not like a complete new operating system.
It will still shared all the memory what you have and you will align it somewhat.
But on top of it, it builds an environment where it is independent of your local server.
That's what we discussed in our previous Section three.
So my goal here is to create one new container and knew what total container.
In that container I can deploy, Tom gets a lot of it, supports my application.
So in the same sort of work model, if another guy comes and deploy any application which have his own
sort of one, don't get some.
For example, it puts upwards Java 14.
Then he can create another container.
So that container is like fresh.
Oh, yes, I can.
It's independent of what we have in the of container.
So like this, a doctor will help us to maintain multiple containments within each container.
It will be like an old watch Wachtel mission.
Right.
On the same line as starboard.
So this move, it will not affect the soft of it if it is deployed in that side of it.
OK.
Now you know what it is.
It it's only one side.
What do you got?
I can simply show by having Tomcat and then deployed.
But in this course, we will fight to understand in real time people started moving through docker containers.
So let's assume that our application is complex and there are multiple options already there.
So that if something gets a lot of with support down seven is already present in our mission in this
land.
Actually, let us in that.
So we the affecting that side of it without affecting any soft targets.
We must Markley create one new docker container, which is a fresh instance, which you do not have
access, which not have any safe twists on the Lennox B and in that fresh in the stance.
Let's deploy our own time Tomcat somewhat.
And we will have this wider file and start the application directly on that side of it.
OK.
No matter how many software suits are already present in this Lennix V, you need not worry because
we are going to containerize our application.
All right.
So that's what I've got.
So we have now assuming that a lot of SW are present.
So let's not disturb any software.
And we will stand.
And you can then up here.
So if you work on all this, you know that you have to first in start docking in your system.
And Twinstar, DOCA, Islamics, you can medically get it from young.
You know that you already have some software.
So just like how you started your volume, install Java.
You can simply install in store.
OK.
So let me go back to.
Linux server and here.
So should I increase the font size?
So don't learn anything.
Do remember that, do you have to be rude?
More pseudo asou hyphen.
Switch to a rude.
OK, now.
Young in star doctor.
OK, just follow this coming.
Right.
Yes.
Perfect.
So doctor is almost getting ready in your system.
It's accomplished great.
So once Dalkia is installed, the next step ought to have to see is like that is a command card groups
to see how many groups are available for road deals.
That means basically how many software groups.
So that can be, again, found in EDC for that.
OK.
So let's go to EDC for that.
I would show that finest present.
So right now you are in the home medically, right?
Let's come back to the origin.
And here you will have EBC for that.
So let's go to CDC.
And inside of this, you have a lot of configurations.
Fine.
So we are interested in having group here.
So, again, you'll see group, even if you can test series group.
That's a fine.
So.
Anyway, so you can say God group, so that content you can watch God group got really nothing, but
it will show the content which is present in this fight.
So right now, all of you may not see here because there are a bunch of fights, but you can see that
with God group coming, you are able to open the content present in this fight.
You'll see that this is the fight.
And you open the contents of that file with this cat gunman.
And he had all the different groups at present.
So you just in started DOCA.
So that means the darker group also is present here.
So make sure you see this darker group in START and you get a groups folder.
You should get it automatically after you, inStar Doctor.
And one thing what I want to show here is.
So basically, Jenkins is trying to connect with this mission, with this easy to hyphen news that right.
So on this easy to hyphen, he goes that only we have them, not waterfloods.
But isn't it?
We have installed a Waterfind successfully in the home pop up, easy to hype and use it.
So basically, we will start Dockett also on that part only.
But by default, you cannot make any modifications.
On doctor with this user, until you give permission, because you have installed the doctor as their
route.
So that doesn't mean that any other user in New Atlantics can use that doctor, OK, to use their doctor.
First of all, you have to give permission to that user to access and utilize the futures of doctor.
OK.
So to get permissions, you have one.
Come here.
OK.
Only that like one time use.
You will not use all this every time because we just giving permissions to our new user to utilize the
docker futures.
OK.
So to give anybody missions that is a command car use sort of more the hyphen a.G.
Right.
So then.
You'll have to go.
Which group?
You have to select here.
I want to select doctor group.
And next you have to give the user name easy to hype and use it.
So basically, this command will give you doctor access to easy to hide, fun, use it.
That's what this command talks about.
You can just Google over the user, more hyphenating and you will find out like this command is used
to give permission to the users group permission.
Right.
Awesome.
So you have now successfully given permission to this user to access doctor.
Great.
Now, let's go back to this user.
We have successfully installed Dalkia and we hadn't made sure we have given proper permissions to access
doctor for this user.
Right now, the next step is log in as that user.
You seem to hype and you if you're simply provide hype and then it will by default in as that road user.
So when you provide use a name, then it will log in and start using me.
So you loved it on that user name, but you'll see that you are somewhere in the EDC folder.
So basically, you need to go to the home for the game.
So silly dot, dot.
And then you are on the origin now from Audism.
You'll have to go to Hombach first.
Isn't it?
That is the place where all users are there.
So you have to go inside this guy so that you will see this operation, which means you are on the home
pop of this user right there.
All right, guys, so we can now start the docket because you have successfully installed it, so to
work on Dalkia to make sure you give Sudhakar mine.
So then only it will allow you to work on, though you have given permission having to access DOCA,
you have to still project Souto so that, you know, you will be able to install a player on with a
doctor.
So how do start.
Dr. Satomi's.
Right.
So some of these Dalkia to start is the command to start the docking in your segment, which we have
already seen in our previous lecture with some commands.
Right.
So make sure you go through all of these comments.
Right.
So those sort of these DOCA start.
Just follow what I'm saying within few like testing will understand.
It's very easy.
So we are trying to start on sort of up in docker container.
That's it.
So you will get a clear picture once a company dissection.
Right.
It's starting the docket, so instead of having that Tomcats are going to reclaim the Lennox because
we are assuming that that is the mother, the Tomcat sort of already in this mission with the end of
that lesson.
So we do we don't want to mess it because there are already some upsets and it's a label on their server.
So that's why we are carefully creating one more new container, which is like fresh instance on that
first instance.
We are playing and downloading all of our stuff.
Great.
So Duncan sort of gets started now when you do, Dr. Pierce.
It will tell you about all comments.
You sorry, what all containers you have in your system right now that have no containers.
It's a blank because you did not create anything.
Okay.
Nice.
So what is our next goal now?
Our next goal is to inStar Tomcat and then run our webapp dart warfighting.
On that down, get in the container.
OK.
We'll see.
They've been our next victim.
Thank you.
