Communicating through the same port

I would like to know if I can have multiple applications in different containers on the same host using the same port each container.For I have several applications that use the same port 8080 and this is giving doors conflict, I have to stop the other contianer spara power Access through the browser. My objective was to save servers by placing the applications in containers on the same host using the 8080 ports, but this is giving port conflicts. So that’s right I can not have multiple containers with applications communicating through the same port?

when you have multiple containers providing port 8080, why not map it on the host system as 8080, 8081, 8082, …?
If you want 8080 for all containers, you need to place nginx or something in front of it.
