Codefresh’s Docker CI service has enhanced its build speed capabilities by introducing full layer caching, a feature previously exclusive to paid accounts, to free accounts as well. This improvement is made possible through Docker 1.13, which allows for the sharing of caches among build servers. As a result, when building an image for the first time, all layers are pulled and cached, and subsequent builds automatically utilize this cache without additional configuration. This automatic caching sets a previous image as the base, eliminating the need to pull layers again, which significantly boosts build speeds. While the specific speed enhancement varies with different applications, benchmarks indicate a typical increase of 5-6 times faster builds, offering users a quicker and more efficient development process.
