Dagger.io is a project that was announced some time ago by Solomon Hykes, and its philosophy caught my attention. It is a CI/CD service that allows running jobs in Docker containers. The added value of Dagger is that it is not limited to Yaml (like Gitlab-CI, Github Action, Drone.io) or a custom DSL (like Jenkins). It allows running jobs using Python, Go, Java, TypeScript, or even GraphQL code. It is somewhat similar to Pulumi but for CI/CD jobs.
