Learn how to create a custom Docker image to run your CI builds on June 18 @10 AM PT. Register now
CircleCI recently released a new fleet of Docker images, which we call convenience images. These images were built with fewer layers making them more efficient. When a build starts, the new images will download faster and they will only be rebuilt for security and critical bugs.
In situations when lots of packages need to be installed, source code needs to be compiled, or downloads are needed over slow connections, this is the sweet spot where your own custom Docker image will shine.
In this webinar, we’ll provide tips on how to create an effective Docker image to be used as the primary image in the Docker executor.
