Docker vs Kontena: What are the differences?
Developers describe Docker as "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. On the other hand, Kontena is detailed as "Docker Container Orchestration Platform Written in Ruby". Kontena is an open source container orchestration tool that makes it easy to deploy and manage containerized applications on your own servers.
Docker and Kontena are primarily classified as "Virtual Machine Platforms & Containers" and "Platform as a Service" tools respectively.
Some of the features offered by Docker are:
- Integrated developer tools
- open, portable images
- shareable, reusable apps
On the other hand, Kontena provides the following key features:
- Automatic Node Discovery
- Mixed Infrastructure Support
- Service Abstraction
Docker and Kontena are both open source tools. It seems that Docker with 54K GitHub stars and 15.6K forks on GitHub has more adoption than Kontena with 1.44K GitHub stars and 117 GitHub forks.
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.
