Now that we've covered a lot of basics
about images and containers
and now that we all also know how we can persist data inside
of a container and how we can work with volumes,
we'll dive into a never key concept
which you will need in most applications
you're going to dockerize and that will be networks
and how you can use networks from inside your containers.
Now with networks here,
i really mean how you can connect multiple containers,
how you can let them talk to each other
but also how you could connect an application
running in a container to your local host machine.
And for example, send HTTP requests
to some other service running on your machine.
And also how you can reach out to the world wide web
from inside your container.
Specifically in this module,
we are going to explore which kinds
of networks we have or where you might want to send requests
to from inside your containers.
And we're going to explore how
we can connect multiple containers
so that they can interact with each other.
