I'm kinda new to this Docker thing and I'm interested in getting a biffed up VPS for some containers (websites/data, mysql, nginx, rocket.chat, etc) but I wouldn't like to access them in the wild (even through SSH) and some VPS hosts's console access are plain cumbersome. So, here's my question:
I've got around 3 separate VPS sharing a common network: 10.0.0.1 thru 10. I'd like to know if, in the host (10.0.0.5) I can set up a docker server, then, inside I can set up an OpenVPN container (or any other kind of VPN) so I can connect from outside to the other VPSes (10.0.0.3, 10.0.0.8, and so on).
Bear in mind that I'm not looking for a privacy-related VPN, I don't want to route traffic nor go outside with the VPS's IP, I just want to "get inside" the internal network I have shared with my VPS (Vultr in case you're wondering, they have a private IPv4 service only for the VMs in my account so it's safe for them) through a VPN for added security and commodity, so I can access a few hosts naturally (and maybe containers as well?) using SSH/RDP/etc. with a single connection instead of having 10 profiles in PuTTY for each server.
Any pointers would be greatly appreciated. Please also take note I'm a newbie regarding docker, I'm a developer & IT guy so I know my way around, but I don't have much idea about networking so I'm not sure if it's possible - and if it is, then can you please tell me how?
Thanks!
