Once completed, you should see the source code for this project. VS Code should reload the window and start building the dev container.Select the first option to create a unique volume.When prompted for the repository to open enter.Select Remote-Containers: Open Repository in Container from the VS Code Command Palette (F1).You can do this on macOS, Windows, or Linux. └── src // Contains sample content for testingįollow the Getting Started Guide install the prerequisites on your development machine. ├── package.json // Includes sample scripts that can be run locally and via Action devcontainer.json // Configuration for the dev container that points to the Dockerfile └── entrypoint.sh // Script to be run inside the container in GitHub Action context ├── Dockerfile // Shared Docker configuration └── action.yml // Defines any available Action inputs and points to the Dockerfile └── main.yml // Defines the trigger, inputs, & specifies Action to run for your project github // Contains GitHub Action and Workflow definitions Example project structure /container-dev-action-sample This POC project attempts to demonstrate one way of doing so. However, through some simple configuration it is possible to use the same container definition for building with GitHub Actions as you do for development with dev containers. Using containers for developing and builds solve a lot of problems separately, but this still leaves teams open to the "it works on my machine" problem if different container definitions are used locally vs. These provide a fantastic way to provide a consistent build environment that includes any needed dependencies and configurations for CI/CD or other types of automation. One option available for building GitHub Actions is by using Docker container actions, which run scripts defined as an ENTRYPOINT to the container. GitHub Actions allow you to create automation workflows in your GitHub repository. This container can be used to run an application or to sandbox tools, libraries, or runtimes needed for working with a codebase. A devcontainer.json file in your project tells VS Code how to access (or create) a development container with a well-defined tool and runtime stack. It allows you to open any folder inside (or mounted into) a container and take advantage of Visual Studio Code's full feature set. The Visual Studio Code Remote - Containers extension lets you use a Docker container as a full-featured development environment. This is a great way to create a shared, reproducible development environment, helping to accelerate onboarding and ensure consistent results. VS Code Devcontainersĭev containers provide a way to develop locally inside of a container whose definition is specified within the source code for your project, including any required dev dependencies and configurations. If you'd like to configure a similar setup using Azure Pipelines instead of GitHub Actions see this post. Note: The source code for the sample project mentioned in this article can be found here. An example for how to share a single Dockerfile defined in a repository for both local development using VS Code dev containers and CI/CD with GitHub Actions.
