How to Set Up a Go Development Container with Docker

Create a devcontainer.json file in your project root to define the Go development environment with Docker.

{
  "name": "Go",
  "image": "mcr.microsoft.com/devcontainers/go:1",
  "features": {
    "ghcr.io/devcontainers/features/docker-in-docker:2": {}
  },
  "customizations": {
    "vscode": {
      "extensions": ["golang.go"]
    }
  }
}

1. Create a .devcontainer folder in your project root and add the devcontainer.json file with the content above.
2. Open the project folder in VS Code and select "Reopen in Container" from the command palette.
3. Run go version in the integrated terminal to verify the environment is active.

Setting up a Go development container with Docker creates a pre-configured environment for your Go projects. It ensures you have the correct Go version, tools, and extensions installed without cluttering your local machine. Think of it as a portable, disposable workspace that looks exactly the same on every computer.
