How do I redirect a service outgoing traffic to another local SOCKS5 service running on port 1080?

Hello,

I want to redirect a service outgoing traffic to another local socks5 service running on port 1080

OS: Ubuntu 20.04

This is what I currently have.

• SSC -> shadowsocks client service (running in docker containers)
• SSS -> shadowsocks server service (running in docker containers)
• Surrounded number in dot lines -> service port

And this is what I really want.

This is where I need a solution.
The solution could be with iptables

I tried these solutions adjusted to my case but they did not work for me:
