How to run many identical programs with different ip without virtualbox?

Question

Computer networks

Good day. Is it possible to run from one computer many copies of the same program and different IPs through a proxy? How can this be done, without virtual machines, they eat a lot of memory and I can’t run more than five pieces at the same time, corny computer resources do not allow .. I was looking for programs to change the ip separately for the application, but there is one dregs. You can’t run the program many times, I could only through the sandbox. Has anyone done this, or do you have any ideas? The question can be reformulated as follows - how to change the ip for each copy of the application launched through the sandbox?

Answer 1

Docker?

Answer 2

Proxifier to help
in the proxifier, you can configure an individual proxy for the unique name of the process being started,
i.e. each instance of the program will need a unique process name to run - (rename the run process proga.exe -> proga1.exe -> proga2.exe ... progaN.exe)

Answer 3

run a bunch of programs with different open ports, and then redirect packets from the necessary IP to these ports with a firewall??
the minimal wrapper is in the container. Docker already told you. See if you can find any other containers. it would be ideal to use OpenVz or LXC, but no luck. You can run them in batches per gigabyte.
try another virtualbox with deduplication of identical pieces of memory in guest systems.
