The example in this repository follows the [dev container Feature distribution specification](https://containers.dev/implementors/features-distribution/). +> +> To provide feedback to the specification, please leave a comment [on spec issue #70](https://github.com/devcontainers/spec/issues/70). For more broad feedback regarding dev container Features, please see [spec issue #61](https://github.com/devcontainers/spec/issues/61). + +## Example Contents + +This repository contains a _collection_ of two Features - `hello` and `color`. These Features serve as simple feature implementations. Each sub-section below shows a sample `devcontainer.json` alongside example usage of the Feature. + +### `hello` + +Running `hello` inside the built container will print the greeting provided to it via its `greeting` option. + +```jsonc +{ + "image": "mcr.microsoft.com/devcontainers/base:ubuntu", + "features": { + "ghcr.io/devcontainers/feature-starter/hello:1": { + "greeting": "Hello" + } + } +} +``` + +```bash +$ hello + +Hello, user. +``` + +### `color` + +Running `color` inside the built container will print your favorite color to standard out. + +```jsonc +{ + "image": "mcr.microsoft.com/devcontainers/base:ubuntu", + "features": { + "ghcr.io/devcontainers/feature-starter/color:1": { + "favorite": "green" + } + } +} +``` + +```bash +$ color + +my favorite color is green +``` + +## Repo and Feature Structure + +Similar to the [`devcontainers/features`](https://github.com/devcontainers/features) repo, this repository has a `src` folder. Each Feature has its own sub-folder, containing at least a `devcontainer-feature.json` and an entrypoint script `install.sh`. + +``` +├── src +│ ├── hello +│ │ ├── devcontainer-feature.json +│ │ └── install.sh +│ ├── color +│ │ ├── devcontainer-feature.json +│ │ └── install.sh +| ├── ... +│ │ ├── devcontainer-feature.json +│ │ └── install.sh +... +``` + +An [implementing tool](https://containers.dev/supporting#tools) will composite [the documented dev container properties](https://containers.dev/implementors/features/#devcontainer-feature-json-properties) from the feature's `devcontainer-feature.json` file, and execute in the `install.sh` entrypoint script in the container during build time. Implementing tools are also free to process attributes under the `customizations` property as desired. + +### Options + +All available options for a Feature should be declared in the `devcontainer-feature.json`. The syntax for the `options` property can be found in the [devcontainer Feature json properties reference](https://containers.dev/implementors/features/#devcontainer-feature-json-properties). + +For example, the `color` feature provides an enum of three possible options (`red`, `gold`, `green`). If no option is provided in a user's `devcontainer.json`, the value is set to "red". + +```jsonc +{ + // ... + "options": { + "favorite": { + "type": "string", + "enum": [ + "red", + "gold", + "green" + ], + "default": "red", + "description": "Choose your favorite color." + } + } +} +``` + +Options are exported as Feature-scoped environment variables. The option name is captialized and sanitized according to [option resolution](https://containers.dev/implementors/features/#option-resolution). + +```bash +#!/bin/bash + +echo "Activating feature 'color'" +echo "The provided favorite color is: ${FAVORITE}" + +... +``` + +## Distributing Features + +### Versioning + +Features are individually versioned by the `version` attribute in a Feature's `devcontainer-feature.json`. Features are versioned according to the semver specification. More details can be found in [the dev container Feature specification](https://containers.dev/implementors/features/#versioning). + +### Publishing + +> NOTE: The Distribution spec can be [found here](https://containers.dev/implementors/features-distribution/). +> +> While any registry [implementing the OCI Distribution spec](https://github.com/opencontainers/distribution-spec) can be used, this template will leverage GHCR (GitHub Container Registry) as the backing registry. + +Features are meant to be easily sharable units of dev container configuration and installation code. + +This repo contains a **GitHub Action** [workflow](.github/workflows/release.yaml) that will publish each Feature to GHCR. + +*Allow GitHub Actions to create and approve pull requests* should be enabled in the repository's `Settings > Actions > General > Workflow permissions` for auto generation of `src//README.md` per Feature (which merges any existing `src//NOTES.md`). + +By default, each Feature will be prefixed with the `` namespace. For example, the two Features in this repository can be referenced in a `devcontainer.json` with: + +``` +ghcr.io/devcontainers/feature-starter/color:1 +ghcr.io/devcontainers/feature-starter/hello:1 +``` + +The provided GitHub Action will also publish a third "metadata" package with just the namespace, eg: `ghcr.io/devcontainers/feature-starter`. This contains information useful for tools aiding in Feature discovery. + +'`devcontainers/feature-starter`' is known as the feature collection namespace. + +### Marking Feature Public + +Note that by default, GHCR packages are marked as `private`. To stay within the free tier, Features need to be marked as `public`. + +This can be done by navigating to the Feature's "package settings" page in GHCR, and setting the visibility to 'public`. The URL may look something like: + +``` +https://github.com/users//packages/container/%2F/settings +``` + +image + +### Adding Features to the Index + +If you'd like your Features to appear in our [public index](https://containers.dev/features) so that other community members can find them, you can do the following: + +* Go to [github.com/devcontainers/devcontainers.github.io](https://github.com/devcontainers/devcontainers.github.io) + * This is the GitHub repo backing the [containers.dev](https://containers.dev/) spec site +* Open a PR to modify the [collection-index.yml](https://github.com/devcontainers/devcontainers.github.io/blob/gh-pages/_data/collection-index.yml) file + +This index is from where [supporting tools](https://containers.dev/supporting) like [VS Code Dev Containers](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers) and [GitHub Codespaces](https://github.com/features/codespaces) surface Features for their dev container creation UI. + +#### Using private Features in Codespaces + +For any Features hosted in GHCR that are kept private, the `GITHUB_TOKEN` access token in your environment will need to have `package:read` and `contents:read` for the associated repository. + +Many implementing tools use a broadly scoped access token and will work automatically.
