What is the difference between lxc and docker?

What is the major difference between Linux and Docker containers? LXC focuses on OS containerization, while Docker thrives on application containerization. Docker is single-purpose application virtualization, and LXC is multi-purpose operating system virtualization.

Do lxc containers have their own kernel?

Linux Containers (LXC) is an operating-system-level virtualization method for running multiple isolated Linux systems (containers) on a control host using a single Linux kernel. LXC combines the kernel’s cgroups and support for isolated namespaces to provide an isolated environment for applications.

What is difference between docker and Kubernetes?

A fundamental difference between Kubernetes and Docker is that Kubernetes is meant to run across a cluster while Docker runs on a single node. Kubernetes is more extensive than Docker Swarm and is meant to coordinate clusters of nodes at scale in production in an efficient manner.

Does docker have its own kernel?

No. Docker image/container only has the application layer of the OS and uses the kernel and CPU of the host machine. In your host machine kernel is already running, so if you boot your docker container it will share the running kernel and start the container so fast.

When was LXC created?

August 6, 2008
LXC/Initial release dates

Can I use LXC without Lxd?

Yes, you could use LXC without LXD. But you probably would not want to. On its own, LXC will give you only a basic subset of features. For a production environment, you’ll want to use LXD.

What is the difference between Docker and LXC?

It is really an extension of LXC’s capabilities. This it achieves using a high-level API that provides a lightweight virtualization solution to run processes in isolation. Docker is developed in the Go language and utilizes LXC, cgroups, and the Linux kernel itself.

Is drivedocker moving away from LXC?

Docker has an interesting relationship with LXC. It was built on top of it (with the micro-service philosophy in mind), but I have since heard/read that they have moved away from LXC (on some level I assume).

What is libcontainer in Docker?

While it started out being built on top of LXC, Docker later moved beyond LXC containers to its own execution environment called libcontainer.

Can you run an OS in a docker container?

Notably, you can also download OS images, which lets you run, say, a Linux system in a Docker container. This is functionality that you would typically associate with LXC containers, which allow you to run OS systems without needing a VM.
