Docker vs Dokku: What are the differences?
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; Dokku: Docker powered mini-Heroku in around 100 lines of Bash. Docker powered mini-Heroku. The smallest PaaS implementation you've ever seen.
Docker can be classified as a tool in the "Virtual Machine Platforms & Containers" category, while Dokku is grouped under "Platform as a Service".
"Rapid integration and build up" is the primary reason why developers consider Docker over the competitors, whereas "Simple" was stated as the key factor in picking Dokku.
Docker and Dokku are both open source tools. Docker with 54K GitHub stars and 15.6K forks on GitHub appears to be more popular than Dokku with 17.7K GitHub stars and 1.44K GitHub forks.
According to the StackShare community, Docker has a broader approval, being mentioned in 3527 company stacks & 3449 developers stacks; compared to Dokku, which is listed in 24 company stacks and 7 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.
