Hi everyone welcome back.
So and this is video we're going to be installing.
Darker and darker compose.
Now we talked about docker in the previous video but we can talk about what Dr. compose is now.
Compose is just basically a tool to control different.
Or when you have multiple containers in darker than it's way easier to control them using Darger right.
So right now we only have one file abduct P Y which represents our entire server right now.
Usually that's not what happens.
Usually you might have one container for the application like flask and then one container for a data
base which we'll talk about for example Mungo NDB or MiSeq call.
And then another container maybe for a different database.
Usually you might have four or five different containers with different applications running in each
of these containers like we discussed in the first video.
And so you don't want to.
You don't want the hassle specially if you want to communicate from one container to the other than
it's usually painful.
And so a dock or compose a tool to just basically make this process a ton easier so you define a file
called Bocker compose not GMO.
And we're going to talk about this a lot later later on.
But for now we're going to download it.
And then this DR-DOS YAML file just controls all of these containers and makes them work seamlessly
you know together and that any problem.
So for now we're going to download doc Creasey and Dharker compose.
So there are different things.
And since we're on a buntu.
So if you want to download it and just type on go go download Dharker Ubuntu and then you should be
click on the first link and then you would come here.
And then you were basically going to be following these instructions over here.
So since you don't have Dharker or any older version of ocher we can get the previous tips and so you
can start following it from here.
So the first step is we're going to copy this over here and we are going to sue to advocate a date so
I'm going to open a terminal controls T.
Or what's the terminal.
So let's open a terminal and see if I can make this bigger for you.
OK.
So hopefully this is big enough for you to see.
And then we're going to paste the first commands you get up to 8 and then input the password and then
it is going to start downloading.
Now I want to come back and get a cost of video now and then want to come back once this has finished.
OK so it's finished fairly quickly so we need to wait too long since my internet connection right now
is not very well good but OK.
So the second thing is I mean we just copy this over here.
The second instruction.
And then when said again and then we go.
And then the third thing is re-occur so we get this copy of this line Ricardo to add the darker official.
Eat the pick.
ZPG.
So he pasted and it gives us an OK here you know it is.
And so now we can you can verify this up over here but I'm fairly certain that it's OK.
And then the next step is to follow it this year.
So since I have a 64 bit system and HMD 64 so I'm going to copy this one over here and paste it
and that's done now.
Now once we've done all this we now want to install ocracy.
So the first step again is to do app and update.
So we're going to copy this and paste it again.
Once we do that then we finally do app and install all Kersee.
So this is what we're interested in.
And so we eat click yes and we let Dog Kersee install so I'm going to let it download and I'm going
to get back to you once it's to
OK.
So welcome back.
So my installation my download is done.
And so now Gawker no knocker should be installed.
So if I want to test it I can just copy this over here and then paste it in my termino and make sure
to run a hello world for a dog or so it's a new locker.
Hello world.
And so our run it but it tells you that it's unable to find the image hello world so it should pull
it and run this Gus where it's pulling it from in a later video.
And yeah you should see this the this message or you're so stators downloaded your image off hello world
and hello from Dharker.
This message shows that your installation appears to be working and so everything is running well and
we have Bulker doctor.
Now let's download and install Dr. compose.
Now once we have a doctor on our system then we want to download Dharker combos that you're going to
come here and since we're on on a bunch of systems we got to use a Linux system.
And so we're first going to do this command over here Sudoku.
And so we click enter and then we're going to wait until it downloads everything and then I'll come
back to you again and we can resume the installation.
OK so welcome back.
So once we have downloaded it we are going to do so do.
Th.
And then we copy this over here and paste it into the terminal.
And so we should have dog or compose now so if you do Dr. compose and then the version you should see
that the darker compose version is the newest version on 0.21 So yeah that's it for this video.
We're just going to download talking to you.
And we already around hello world for dark or if you're here so it works fine.
So we have both darker and darker Contos And so from now on we can start working on the project and
see how we can fit everything into darker.
So yeah until the next video.
