All right.
We have just successfully agreed that the world press container and the we were even able to connect
to WordPress admin web page and start performing initial configuration setup.
But here we were asked to answer credentials for connection to my Maya school database.
But this database is absent at the moment and there isn't for that is simple WordPress itself is shipped
without Maya skill database and does because in Docker there was a principle of single responsibility.
And basically every container should be responsible for single process single service.
And that's why if you want to create a wordpress website you need at least two containers WordPress
container and Maya grill container.
And of course connect them together.
And here we come to important topic connection between containers on one computer or on different computers.
And the here we will ACARA basically different concepts forced networking.
It is important to understand how containers we communicate with each other.
Second environment variables.
When you start for example my go container.
You need to provide at least a root admin password and for that you need to use an environment variable.
Also it is important to understand what is cast on network because in custom networks in Docker containers
may communicate between each user by using a curtain names as a DNS host names and all those concepts
we will cover in the next layer Charles.
And let's start by talking about the communication between containers in default breach network and
for that we will create the two busy box containers and I'll explain you how you're able to build one
container from another.
I'll see you in the next lecture by.
