Is it possible to deploy Docker on a VPS?

Question

System administration

Good afternoon Toasters!

This technology is still unknown to me, I went to read it, but I feel I won’t master it until the end of the day, but it became necessary to move to a new hosting (in particular, to reg.ru on OpenVZ).
I sadly remember how much effort was put into setting up the previous hosting (I'm not a system administrator), and it seems to me that I found what I need ))
I want to install Ubuntu 16.04, ISPManager, LAMP, Postfix, Spamassassin, and a whole lot more .. And it would not be bad to take this zoo later, if necessary, and deploy it on another hosting.

Tell us in a nutshell:
1) Is this possible on VPS hosting?
2) Is it true that having deployed hosting using docker, I will later transfer it to another as it is? That is, with a customized environment, software and your applications? Or just software and environment?
3) Give a link where briefly, in fact, what is it, maybe an example of setting up a VPS?

All the best! )

Answer 1

Is this possible on VPS hosting?

Yes.
On OpenVZ, most likely not, because. it's not a full VDS: you don't have access to configure the kernel and install additional modules.
This virtualization system is on the same level as docker.
If you take a normal VDS, for example, on KVM, then everything will be fine.

Answer 3

You clearly did not understand the essence of docker, what you described is not about docker at all, use conventional virtualization or just copy the server in a sync.

Answer 4

Docker is up on an OpenVZ VPS with a kernel version of 042stab105.4 . It will be difficult for you to find such VPS, I myself know only one such hoster. I just don’t understand why you need OpenVZ when there are a lot of normal and affordable KVM options around, where you can usually put anything you want.

Answer 5

What is the problem?
If you have root access, it's no problem to install docker-engine, docker-compose and everything else and run both docker containers and compose files.

Answer 6

Docker works great on VPS, there were no problems with installation and use.
