Now in this lecture,
we're going to
install Docker for Mac OS.
And therefore on this Get Started page
on docker.com.
Here, under Docker Desktop,
we're going to download the version for Mac,
it should automatically preselect the right one.
If it didn't,
you can simply switch to it.
So click this and download this to some folder
of your choice.
This is just the installer basically.
So it's really
up to you where you wanna store it.
And I will be back once this download finished
to then show you the very, very,
very complicated,
not,
Installation process.
And to then also show you how
to finish up the installation
and what's important to keep in mind
when it comes to working with Docker.
So, download finished,
now we can execute this file here
on Mac OS
and let it open the Docker DMG file.
And now the installation really is just that you drag
this Docker app,
which for you might have a real Docker icon
and not this placeholder,
which for whatever reason I have here
and drag that
to the Applications folder.
That really is all,
this will now copy over Docker.
And once this is done,
you can close this
and simply run Docker.
You will now have this Docker app available
as an application you can run.
So I'm running it here.
And you now see this whale here
in the status bar on top.
Now here, you can go to preferences,
to bring up this graphical user interface here.
And there, you can set up
some general things, you can for example,
control whether Docker Desktop should start
when your Mac starts,
you can set up automatic updating,
and you can also configure other things.
Some of these things or settings are
topics I'll come back to later
in the course.
For example, file sharing.
Generally you should be fine
with all the defaults here.
Only change things if you know what you're doing.
Besides the start up thing here,
which of course is up to you whether you want
to have this changed or not.
Now, one important note is that
on the bottom left corner here,
you will see that Docker
is currently running.
And it will start
whenever you start Docker Desktop.
So if you don't automatically start it with startup
of your system,
you should start it manually by running
this Docker app before you try
to run any Docker commands against it.
Because all those commands which you'll see
throughout the course,
which we execute in the command line will
only work if Docker is running.
So you should always make sure
that you started Docker, for example,
by starting the Docker Desktop app in order
to run commands thereafter.
Now with that,
that's it for the moment,
you can close this window.
It's still running here as long
as you have this icon here.
And you can always shut Docker down with
this menu here.
But for the moment,
I'll keep it up and running.
And again, make sure it is
up and running when you plan
on working with it.
And that's already it
with the Docker for Mac OS setup.
For older versions of Mac OS,
check out this extra lecture which comes
after the next lecture.
And for Windows,
also check out that next lecture.
And with that,
you'll then be ready to dive into Docker
and start writing some commands to learn
how Docker really works
and what you can do with it.
