How will a php & nodejs application work in dockere?

Question

PHP

I want to understand how docker works. I want to build an application in php (apache). But part of the requests will be processed by nodejs.
Do I think correctly that I should create 2 containers on different ports (One Apache, the second node)?
And if I want to split the application itself into modules - can I somehow store these modules in images along with the environment?

Answer 1

You can put everything in one container if you want. Weird, but quite workable.
You can keep a container with php + apache, and the application code in a folder nearby. Same with node.
Not necessarily on different ports, containers can not be opened to the external network at all, but then you need a reverse proxy. This is for development.
You can make a new image that inherits from php+apache and contains your application.
Then it will be enough to upload one image file to the server and run the container based on it. This is for a quick deployment. But it will be necessary to update the container and repeat the procedure.

Answer 2

Yes.
