Docker vs Docker Machine: 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 Docker Machine? Machine management for a container-centric world. Machine lets you create Docker hosts on your computer, on cloud providers, and inside your own data center. It creates servers, installs Docker on them, then configures the Docker client to talk to them.
Docker belongs to "Virtual Machine Platforms & Containers" category of the tech stack, while Docker Machine can be primarily classified under "Container Tools".
"Rapid integration and build up" is the primary reason why developers consider Docker over the competitors, whereas "Easy docker hosts management" was stated as the key factor in picking Docker Machine.
Docker and Docker Machine are both open source tools. Docker with 54K GitHub stars and 15.6K forks on GitHub appears to be more popular than Docker Machine with 5.4K GitHub stars and 1.56K GitHub forks.
Spotify, Pinterest, and Twitter are some of the popular companies that use Docker, whereas Docker Machine is used by Docker, DNT, and Medallia. Docker has a broader approval, being mentioned in 3527 company stacks & 3449 developers stacks; compared to Docker Machine, which is listed in 43 company stacks and 47 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.
