Set the default devcontainer image for repositories without a devcontainer configuration. Useful when:
  • Standardizing base tooling across all environments
  • Pre-installing company-specific tools or certificates
  • Using internal images from a private registry

​
Configuration

Enter a container image reference (e.g., mcr.microsoft.com/devcontainers/base:2.0.4-noble). If empty, uses system default.
Using private images? Set up container registry credentials first.
