If it works in Docker,
it works on CircleCI
Complete flexibility to run any Docker command so you can ship faster than ever before.
Developers that build in Docker use CircleCI for maximum efficiency
The best tools for the job
-
The flexibility to choose the resource class that matches the CPU and RAM you need on each individual job.
-
Ship faster by completing runs on hundreds of Docker tasks at once using parallelism and test splitting.
Optimize developer time
-
Get faster image downloads using CircleCI’s pre-built Docker convenience images.
-
Docker layer caching means unchanged layers of your Docker image are reused and readily accessible for maximum speed.
Easily customize images
-
Tailor your execution environments by creating and using Docker images designed by your team.
-
Start with a pre-built convenience image and build your own image on top of it for complete customization.

Featured convenience images
CircleCI maintains a registry of pre-built Docker images. Our system allows images from outside of our registry but convenience images are built with CI/CD in mind: small, fast, and simple to download.

-
"From simple setup and easy integration across GitHub, Chat apps, Docker (and more) to the ability to deploy to different environments from production, QA, and staging, CircleCI has proven to be completely indispensable for our business."
Toshimasa Ishibashi
Co-founder and CTO, Kaizen Platform -
"The fact is that in today’s world, companies need to make merge time to deploy time as short as possible. When looking for a CI solution that can scale really quickly, parallelize, distribute and optimize the run time in the split—and manage Docker as a first class citizen to help us manage the many systems inside — CircleCI comes out on top."
Rob Witoff
Former Director of Infrastructure & Security, Coinbase -
"Workflows + Docker caching are great with CircleCI. I’m pumped about what we can do with this! Our Docker build times have gone from ~12 minutes to less than 2 minutes on CircleCI. Fan-freaking-tastic."
