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.

Install / run

go install dagger.io/dagger/cmd/dagger@latest

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

Quick start

1Create a new Dagger configuration file named `dagger.json` in your project root
2Define a `plan` in `dagger.json` to specify the build, test, and deployment steps for your project
3Run `dagger do` to execute the plan and automate the build, test, and deployment process
4Use `dagger login` to authenticate with the Dagger cloud and enable remote execution
5Configure your CI/CD pipeline to run `dagger do` on each code commit

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
