Docker-capable VPS

blizzfire

Hello,

I just found that my existing OpenVZ-based VPS services do not support docker due to their kernel version being lower than 3.10.0 (Docker requires 3.10.0 or higher). Upgrading the kernel is not possible, I tried running apt-get upgrade etc.

Therefore, I am looking for VPS providers / services that allow me to run Docker.

Can you suggest any? What do I have to look for? Does it need to be a dedicated VPS?

Cheers !

Practically every KVM VPS supports Docker as you have full control over the kernel.

Vultr/DigitalOcean/ExtraVM/FlowVPS/Ho-ost/etc. all have KVMs that can run Docker.

As for your last question: it does not need to be dedicated — just make sure that you avoid getting another VZ VPS (unless a provider explicitly mentions that they’ve enabled Docker in the kernel).

Thanks! This means that OpenVZ are (by default) not Docker-capable if not manually activated by the provider or is it due to their kernel version?

+1.

OpenVZ7 should allow docker without provider input, correction: just tested, still needs modules loading.

Correct.

or is it due to their kernel version?

Yes and no.

Well, if you need a custom kernel, or a specific version, or specific kernel modules, then don't use containerization - such as OpenVZ, use virtualization - such as KVM instead.

Thank you for all your replies! I'll go with KVM-based virtualization then. Cheers

Your services are already in a small virtual container more often than not, what's the usual use case for those of you that are using Docker?

Well yes, but no.

I loved OpenVZ because it worked without significant overhead and it was a lot cost effective.
It provided the Low in LowEnd.

What is your location and/or target geography for the dockerized app?

Do you have an annual budget or just a monthly one?

How much RAM does all your docker containers require( together on same KVM)?

Hi
We provide OpenVZ as well as KVM VPS, for OpenVZ just submit a support ticket after placing order we will enable Docker support for your VPS

My advice is to get KVM and to use that, you can use any kernel you like and it's a lot more likely to work without any headaches. Much like FUSE on VZ, it can be done, but it's not the same as FUSE in a KVM.
