Docker vs kaniko: 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, kaniko is detailed as "Build container images in Kubernetes". A tool to build container images from a Dockerfile, inside a container or Kubernetes cluster kaniko doesn't depend on a Docker daemon and executes each command within a Dockerfile completely in userspace. This enables building container images in environments that can't easily or securely run a Docker daemon, such as a standard Kubernetes cluster..
Docker belongs to "Virtual Machine Platforms & Containers" category of the tech stack, while kaniko can be primarily classified under "Container Tools".
Docker and kaniko are both open source tools. Docker with 54.4K GitHub stars and 15.7K forks on GitHub appears to be more popular than kaniko with 4.14K GitHub stars and 334 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.
