Quickstart
In this guide, you will create a basic Dagger configuration for your project, and run your first Checks locally.
Complete Try Dagger before you start.
Dagger configures the project that you run it in. Run every command in this guide from your project root.
Install modules
Initialize the workspace:
dagger init
This creates an empty dagger.toml, or uses the existing file. This file holds the workspace configuration for everyone who uses the repository.
In interactive mode, follow the optional setup prompts. Select modules that match your project. Then select Install selected.
In non-interactive mode, init prints commands to run in order:
#!/bin/sh
# 1. Find and install recommended modules.
dagger module recommend
# 2. Enable Cloud checks (optional).
dagger cloud checks on
If init detects a legacy workspace, it stops without changing files. Run dagger workspace migrate to review the migration. After migration, Dagger offers the same next steps.
Migration includes installed local modules. Other module candidates are optional and can include fixtures. Non-interactive migration skips these candidates, including with --auto-apply. To migrate one explicitly, run dagger module migrate PATH.
If no modules are recommended
If Dagger reports No recommendations, search for a module by the name of a tool in your project. For example, if the project uses ESLint:
dagger module search eslint
dagger module install dagger.io/js/eslint
Configure modules
Most modules use suitable default settings. List the available settings:
dagger module settings
Change a setting when the default does not match the project. For example, if you installed ESLint and the project uses Yarn:
dagger module settings eslint packageManager yarn
Settings are stored in dagger.toml, so they apply to all users of the workspace.
Run Generators and Checks
List the workspace Generators:
dagger generate -l
If the list is not empty, run them:
dagger generate
Review the changes. Apply them when requested.
List the Checks:
dagger check -l
If no Check validates your project, install another suitable module. If at least one does, run the Checks:
dagger check
You are done when at least one Check runs and all Checks pass.
