If it works in Docker,
it works on CircleCI
Developers that build in Docker use CircleCI for maximum efficiency
The best tools for the job
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.Browse the Developer Hub

"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 IshibashiCo-founder and CTO, Kaizen Platform
"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."
Josh DoverSenior Software Engineer, CrateJoy
"Since we implemented Docker layer caching, we’ve saved about 2,000 hours of developer time in the last six months. Likewise, our ability to turn around fixes has shortened by 50% or more."
Travis MatteraSenior Site Reliability Engineer, Rollbar
