Check Use the WSL 2 based engine and verify your distribution is enabled under Resources > WSL Integration. If you are using WSL 2 on Windows, to ensure the WSL 2 back-end is enabled: Right-click on the Docker taskbar item and select Settings. Install and configure Docker for your operating system. Other glibc based Linux containers may work if they have needed Linux prerequisites. Note that attaching to a Kubernetes cluster only requires a properly configured kubectl CLI. Other Docker compliant CLIs may work, but are not officially supported.

Remote hosts: 1 GB RAM is required, but at least 2 GB RAM and a 2-core CPU is recommended.(The Ubuntu snap package is not supported.) Linux: Docker CE/EE 18.06+ and Docker Compose 1.21+.Windows container images are not supported.) Windows 10 Home (2004+) requires Docker Desktop 2.3+ and the WSL 2 back-end. Windows: Docker Desktop 2.0+ on Windows 10 Pro/Enterprise.Note: You can learn how to get up-and-running quickly with dev containers in the introductory Dev Containers tutorial. You can attach to a running container to inspect it.You can use a container as your full-time development environment.The Dev Containers extension supports two primary operating models: This lets VS Code provide a local-quality development experience including full IntelliSense (completions), code navigation, and debugging regardless of where your tools (or code) are located. This means that you can seamlessly switch your entire development environment just by connecting to a different container. Extensions are installed and run inside the container, where they have full access to the tools, platform, and file system. Workspace files are mounted from the local file system or copied or cloned into the container.

This container can be used to run an application or to separate 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 Dev Containers extension lets you use a container as a full-featured development environment.

Configure IntelliSense for cross-compiling.
