You can also create a Dynamics 365 Business Central sandbox environment without using the sandbox links to the Business Central production tenant, but instead using custom scripts for creating Docker-based sandboxes hosted locally or on Azure Container Instances.
After installing Docker for Windows on your local machine, you can manually create a Docker-based Dynamics 365 Business Central container by running a script that pulls a container image from the Docker hub.
From Command Prompt, you can execute the following command:
docker run -m 4G -e ACCEPT_EULA=Y -e UseSSL=N microsoft/bcsandbox:latest
This will create a Dynamics 365 Business Central container with the latest image available.
If you want to create a sandbox with a particular localization (for example, IT), you can run the following command:
docker run -m 4G -e ACCEPT_EULA=Y -e UseSSL=N microsoft/bcsandbox:it...
