Docker vs LXC: What are the differences?
What is Docker? Enterprise Container Platform for High-Velocity Innovation. The Docker Platform is the industry-leading container platform for continuous, high-velocity innovation, enabling organizations to seamlessly build and share any application — from legacy to what comes next — and securely run them anywhere.
What is LXC? Linux containers. LXC is a userspace interface for the Linux kernel containment features. Through a powerful API and simple tools, it lets Linux users easily create and manage system or application containers.
Docker and LXC belong to "Virtual Machine Platforms & Containers" category of the tech stack.
Docker and LXC are both open source tools. It seems that Docker with 54K GitHub stars and 15.6K forks on GitHub has more adoption than LXC with 2.66K GitHub stars and 797 GitHub forks.
According to the StackShare community, Docker has a broader approval, being mentioned in 3523 company stacks & 3442 developers stacks; compared to LXC, which is listed in 11 company stacks and 5 developer stacks.
lxd/lxc and Docker aren't congruent so this comparison needs a more detailed look; but in short I can say: the lxd-integrated administration of storage including zfs with its snapshot capabilities as well as the system container (multi-process) approach of lxc vs. the limited single-process container approach of Docker is the main reason I chose lxd over Docker.
