How many docker containers can be run on a single server?

Question

Docker

There is a server on the latest Ubuntu with the following characteristics:

• 2GB/1CPU
  
• 50GB SSD drive
  

How many containers can I run on such a server? Are there any internal limits in docker itself?

For simplicity, let's assume that each container will just run Nginx.

Answer 1

Depends on the running process in the container. If you limit the container in memory back to back, then the process may terminate with an error due to lack of memory. The same nginx can consume a different amount of memory depending on the modules, settings and load.

Answer 2

eight
count 15% of the CPU for one
