What it does

Dagger is a automation engine that streamlines build, test, and deployment of any codebase, running locally, in CI, or directly in the cloud.

When to use it
  • •When you need to automate repetitive development tasks across multiple environments
  • •When you want to integrate automated testing and deployment into your CI/CD pipeline
  • •When you need to manage complex workflows across different teams and projects
Ready-to-paste prompt
dagger do myproject/build -p myproject/test -p myproject/deploy
Heads up: Dagger requires Go 1.18 or later to be installed on your system, and you need to set the `DAGGER_LOG_LEVEL` environment variable to control the verbosity of the output
