Codefresh is a DevOps platform tailored for containers and Kubernetes, with its core feature being the Codefresh pipelines that provide Docker in Docker (DinD) functionality as a service. This setup influences how pipelines are constructed, supports multiple programming languages, and manages tooling by allowing each step to run in its own container. Users can define custom steps by specifying Docker images, which function as direct plugins for the pipeline, enabling actions like posting messages with Slack via the curl image. Beyond executing singular images, the platform's DinD service can spin up multiple images simultaneously for complex compositions, such as running performance tests with Taurus against Blazemeter. Each pipeline step maintains a persistent volume, facilitating information sharing, caching, and integration of tools like JIRA, enhancing the flexibility and efficiency of development workflows. To begin using Codefresh, users can create a free account and access extensive documentation for guidance.
