Workspace Setup
You've seen Dagger work on hello-dagger. Now set it up on your own project.
Get started​
From the root of your repository:
dagger mod recommend
dagger mod recommend scans your project and suggests modules for the tools, frameworks, and languages it detects.
The feedback loop​
Install the modules you want from the recommendations, then run dagger check:
dagger mod install github.com/dagger/eslint
dagger check
dagger mod install creates a workspace configuration (.dagger/config.toml) if needed and adds the selected module. dagger check runs checks from installed modules. Repeat until you're happy with your coverage — you don't have to install everything at once.
You can also search for a specific module:
dagger mod search eslint
Manual setup​
If you already know which modules you want, install them directly:
dagger mod install github.com/dagger/eslint
dagger mod install github.com/dagger/vitest
dagger mod install github.com/dagger/prettier
The first install creates .dagger/config.toml at the workspace root. To create the config in the current directory instead — for a workspace nested inside a larger repository — initialize it explicitly with --here:
dagger ws init --here
Configure modules​
Many modules expose settings — a base image, a package manager, and so on. List the settings for your installed modules:
dagger ws settings
Set one with module, key, and value:
dagger ws settings eslint packageManager yarn
Settings are stored in .dagger/config.toml alongside each module, so they're shared with everyone who uses the workspace.
Migrate an existing project​
If your project already uses a legacy dagger.json, convert it to the workspace format:
dagger ws migrate
This writes .dagger/config.toml from your existing configuration. See Upgrade to Workspaces for details.
What's next​
- Add to CI —
dagger ws autocheck onenables Cloud Checks for a GitHub repository, ordagger checkcan run in any existing CI provider - Vary config per environment — use Environments when staging and production need different settings
- Manage secrets — if your checks need credentials, see Secrets
