All language subtitles for 003 Windows Docker Options_en

All right. You're a Windows user and you want to get Docker working.

So let's get you to it. In this lecture,

you're going to learn the two types of containers that can now run on Windows.

You're going to get through which Docker edition you want to install based on your version of Windows

and your edition of Windows. You're also going to learn the difference between Windows 10 and server 2016

and how the desktop and server treat Docker a little bit differently.

Then the next lecture is going to get to installing it.

There are two types of containers

now on Windows, which is really cool. We have the options now for Linux containers, or

up until recently, we just called them containers, because that was the only type of container we had.

Now we have Windows containers.

This course, by default, is actually going to talk about Linux containers because we've had those

for four plus years and that's everything that we all know about containers was Linux based.

It was only till late 2016 that Microsoft really formalized the concept of a Windows container and made

it usable and they're rapidly innovating.

So it's a pretty exciting space.

But most of the concepts are the same.

You're going to use them the same way. You're going to manage them the same way.

It just matters that binaries that are running inside them you know SQL, EXE vs MySQL

on Linux or something.

So, we're going to talk in this course about containers. When I say that I really mean Linux containers.

When I talk about specifically on Windows containers,

I will say Windows containers so that we're clear.

OK.

The best version of Docker on Windows is Docker for Windows.

That's actually an edition of Docker and it's got a whole install that we'll see a moment and it's

really great on Windows 10.

It only works on Pro and Enterprise

Unfortunately. If you have the Home version of Windows 10 or an older version of Windows, it's not going

to work.

In those cases you're going to use the Docker Toolbox, which was the only option we had until a year ago

so it's still a great option.

It's still updated. It's still supported.

It's just not going to have all the nice cool features that Docker for Windows has because Windows 10 has

new innovations in it using Hyper-V that we just don't get in those old versions, unfortunately,

of Windows. Now with Server 2016, it does support Windows containers.

We won't go in a whole lot into that in this course because that's still really new stuff and they're

making major changes. Even just 3 or 4 months ago, they added a whole new networking feature set

to it.

So it's a rapidly evolving ecosystem.

I will continue to update this course and any other courses with all that stuff as well. Just as

an example of what that's like is, we had in the spring not only this new networking overlay networking

that we'll get into later in the course, but we also have native Linux containers that we haven't even

seen yet.

But Windows announced it at DockerCon and that basically is some feature we're going to see in the near

future that supposedly will have Windows intelligently and automatically figuring out when you want

to run a container whether it should be on Linux or Windows and then do that for you.

Today we have to manually specify. They're supposedly going to make some new feature in the future that

works on that.

That's something that nobody else is doing.

No other platform is doing that so it's pretty cool to be on Windows.

It's just evolving rapidly so be prepared.

If you're on Windows 10 Pro in Enterprise, you're one of the lucky few that get to actually run Docker

for Windows. You can get that from

store.docker.com. It's actually got more features than if you just installed Linux in a Linux VM on your machine.

So if you're tempted to just say, 'screw it. I'm just going to install Linux VM and I'm going to install

Linux on it.'

Well, that would work like a server in the cloud, like a Linux production server might, but the Docker for

Windows and the Docker Toolboxes are really helping you develop and test stuff locally. So it does things

like map drives from your host operating system into the container, and we'll get to that stuff later.

But it's worth trying

OK, before you go that other route. In the background, Docker for Windows is actually using Hyper-V, which

uses a tiny little Linux VM for the Linux containers.

So if you're on Windows 10 Pro or Enterprise right now and you have a VirtualBox or VMware, they may

not work with Hyper-V. I know VirtualBox and Hyper-V don't play well together so you may have to Google

around the Internet for solutions on trying to get those to work right

if you want to use both.

Personally, I just decided to shift everything in the Hyper-V once Docker shifted into Hyper-V.

It is PowerShell native, which means in this course, if you're on Docker for Windows, I expect you to be using

PowerShell and I will show you commands on how to do that.

You can get other shells to work if you're a shell ninja and you like Bash or you like the old command

prompt.

That's fine. On Docker for Windows 7, 8 and 10 Home, we already use a Docker Toolbox which is not as fancy

as the Docker for Windows but it's still great.

Still works fine.

You could use it every day.

Like others, you're going to download that at store.docker.com and it does run a tiny little Linux

VM in the background, and it uses VirtualBox and it uses a command line called Docker Machine to manage

that VirtualBox and you'll see that later in the course as well.

If you just want to learn how Docker Machine works right now, you can actually just go Google it, and

It'll give you great instructions on how you use Docker Machine command line to create VMs and destroy them.

You can actually create multiple Docker machines if you wanted.

Now in this machine that comes by default with a Toolbox,

it comes with a Bash shell called the Docker QuickStart terminal, I believe is it's called, and that's

what I expect you to use in this course.

That's the one that's going to work the best.

It's going to auto start things and make sure everything's working correctly.

If you're more savvy and you wanted to get into other options for shells, I might give you some tips

along the way, but I can't really support every shell in every possible configuration for your environment.

So I'm going to focus on how Docker provides it out-of-the-box.

Note that those versions of Windows that we're talking about right now do not support the Windows containers.

They only support the Linux containers in that small little VM.

Lastly, just a note about Windows Server 2016 as it is a part of this course and it supports Windows

native containers, so it runs a Windows binary, out-of-the-box, without Hyper-V or anything installed in

a Docker container, which is pretty cool.

It does also support Docker for Windows, but Docker for Windows is really a tool kit for local development

and testing.

It's not meant as a production tool.

The only reason I would tell you to do this is if you had Windows Server installed on your local

machine as a replacement for Windows 10, right.

Some developers do that. They develop locally on Windows Server because that's the platform they use

in production and they like to develop on that platform.

So, if you're doing that, totally install Docker for Windows. It'll give you a better experience. But if

you're in production, don't do that. You really want to run Docker Windows containers natively on Server

2016.

And if you're going to do Linux containers, you run those natively on Linux, not on Docker for Windows

in production.

The previous versions of Windows don't really support anything with Docker unless you're talking about

a previous version of Windows that's running Hyper-V and that's running on your bare metal.

And then you just run a Linux VM.

Of course you can do that.

You can do that anywhere. Anywhere you can run a VM you can put Linux on it and that can run Docker. So

that one is definitely still on the table

if that's the way you want to go.

But in this course I'm not going to expect you to be developing and testing on Server 2016.

I'll assume that you're on Windows 10 or Ubuntu or Mac or something.
