It’s a shame openVz pioneered container, yet docker ate their lunch
- pjmlp 3y agoOn GNU/Linux, I was already using containers in HP-UX via Vaults in 1999.
- dusted 3y agoI used OpenVZ for a long time before Docker came along, it was certainly nicer than what I did previously (run everything right on the host) but, of the two, I'd pick Docker every time. Dockerfiles, images, layers, thinking of containers as "application instances", the networking, the cli, the speed, there's nothign I miss from OpenVZ, even if it was good for what it was, the way Docker improved on it made a very big difference, in a positive way.
- antod 3y agoDocker didn't bring container running features or kernel features for running containers (they just used LXC at first didn't they?), Docker brought an image layering and distribution set of features for single process containers. OpenVZ (like LXC) was more of an OS level VM alternative type of container. Docker was more of a developer oriented distribution/isolation system than OpenVZ/LXC/etc which were more of a sysadmin oriented hosting system. In the very early days Docker didn't make much sense to me until I realised that.
