dagger 命令

常用示例

说明

dagger is a CLI for a portable build engine that executes pipelines as code rather than YAML. Each pipeline is expressed as a function in Go, Python, TypeScript, Java, PHP, or Elixir using the matching Dagger SDK. Functions take typed inputs (directories, secrets, services, primitives), describe a graph of containerized operations, and return typed outputs. The engine runs locally on Docker, Podman, or any OCI-compatible runtime, and identically inside any CI (GitHub Actions, GitLab CI, Jenkins, CircleCI, Azure Pipelines, Buildkite). Because every step is content-addressed and cached, repeated calls reuse prior results, making local iteration as fast as the CI run. dagger call is the primary entry point: it locates the module (defined by dagger.json), invokes the requested function with the provided flags, and streams the result. Modules can compose other modules from local paths or Git URLs, enabling reusable building blocks across projects and organizations.

参数

call

Invoke a function from the current module; arguments are passed as --flag=value pairs and outputs are streamed back.

init

Scaffold a new module in the current directory. Requires --sdk to choose the language.

develop

Regenerate code bindings after editing dagger.json or adding dependencies.

install

Add a module reference (local path or remote Git URL) as a dependency.

run

Execute an arbitrary command with a transient Dagger engine session, exposing the engine on DAGGER_SESSION_PORT.

query

Send raw GraphQL queries to the Dagger engine (read from a file or stdin).

login / logout

Authenticate against Dagger Cloud for pipeline traces and caching.

-m, --mod _REF_

Use a remote module instead of the local one (e.g. github.com/dagger/dagger/ci).

--progress _MODE_

Progress UI: auto, plain, or tty.

--silent

Suppress progress output entirely.

-v, --debug

Verbose / debug logging.
