Containers - Docker-in-Docker support added to Containers and Sandboxes

Sandboxes and Containers now support running Docker for "Docker-in-Docker" setups. This is particularly useful when your end users or agents want to run a full sandboxed development environment. This allows you to: Develop containerized applications with your Sandbox Run isolated test environments for images Build container images as part of CI/CD workflows Deploy arbitrary images supplied at runtime within a container For Sandbox SDK users, see the Docker-in-Docker guide for instructions on combining Docker with the SandboxSDK. For general Containers usage, see the Containers FAQ .
