GitHub Copilot CLI Dev Container Feature

This repository packages a Dev Container Feature that installs and configures the GitHub Copilot CLI inside VS Code Dev Containers and GitHub Codespaces.

Contents

• src/copilot-cli: Feature implementation (feature.json, install script, documentation).
• test/: Automated tests using the Dev Container Features test harness.
• examples/: Sample devcontainer.json configurations.

Getting started

1. Build the feature locally:

   devcontainer features build src/copilot-cli
   

2. Run tests:

   devcontainer features test src/copilot-cli
   

3. Publish to a registry once you're satisfied (for example GitHub Container Registry):

   devcontainer features publish src/copilot-cli --namespace your-org/features
   

Distribution

• GitHub Actions workflow – .github/workflows/publish.yml publishes the feature collection to ghcr.io whenever you push a semantic tag (for example v0.1.0) or trigger the workflow manually.
• Local helper script – distribution/local-ubuntu-docker.sh replicates the automated publish process on an Ubuntu host with Docker installed. It runs the Dev Containers CLI from a container so no additional tooling is required on the host.
