Adding features to a devcontainer.json file

1. Navigate to your repository on GitHub, find your devcontainer.json file, and click to edit the file.

   If you don't already have a devcontainer.json file, you can create one now. For more information, see Introduction to dev containers.

2. To the right of the file editor, in the Marketplace tab, browse or search for the feature you want to add, then click the name of the feature.

   

3. Under "Installation," click the code snippet to copy it to your clipboard, then paste the snippet into the features object in your devcontainer.json file.

   

   "features": {
        // ...
        "ghcr.io/devcontainers/features/terraform:1": {},
        // ...
    }
   

4. By default, the latest version of the feature will be used. To choose a different version, or configure other options for the feature, expand the properties listed under "Options" to view the available values, then add the options by manually editing the object in your devcontainer.json file.

   

   "features": {
        // ...
        "ghcr.io/devcontainers/features/terraform:1": {
            "version": "1.1",
            "tflint": "latest"
        },
        // ...
    }
   

5. Commit the changes to your devcontainer.json file.

The configuration changes will take effect in new codespaces created from the repository. To make the changes take effect in existing codespaces, you will need to pull the updates to the devcontainer.json file into your codespace, then rebuild the container for the codespace.
