Using Dagger with Docker for better CI/CD

Dagger is an open-source development kit that enhances CI/CD pipelines by allowing them to be run both locally and in the cloud, aiming to simplify the complexity associated with traditional CI/CD tools. By using Dagger with Docker, developers can automate actions with their preferred programming language, test and debug locally, and integrate with existing pipelines on any Docker-compatible runtime. Dagger's architecture is based on the CUE configuration language and BuildKit, allowing for the execution of configurations in a client-server model similar to Docker. The tool facilitates the creation of reusable and modular components, replacing intricate Bash scripts with more streamlined processes. This flexibility is particularly beneficial for developers who frequently switch between different CI/CD stacks or require rapid iteration and debugging. Additionally, Dagger supports building container images by embedding Dockerfile contents directly within its configuration files, promoting a more efficient and portable workflow.
