Learn how to create a custom Docker image to run your CI builds.

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.

This webinar will not, however, cover how to build and publish a Docker image that will then be used in your production environment or to distribute your open source application.

In this webinar, you’ll learn:
  • Utilizing caching for faster spin up times
  • Speeding up larger workflows with Docker layer caching
  • Building and test faster with parallelization
  • Live Q&A
