2. Docker Toolbox is implemented by creating a virtualBox virtual machine. The virtual disk of the virtual machine is in C:\Users\username\ by default. Under .docker, if there is not much space left on your system disk, errors will occur when you use it later. You can use the virtual media management in virtualBox to move to other disks

3. Use Docker Quickstart Terminal to run the service and then turn it off (of course it can be used directly here, but I cannot copy it on this command line) and paste), then open git bash where you need to run the command

4. If your docker-compose folder is not under C:\Users\username\.docker, then you need to go to virtualBox Set up shared folders. For example, the path is D:\docker, the shared folder name is d/docker, and the fixed mount and automatic allocation are checked. After shutting down the virtual machine, just use Docker Quickstart Terminal to start it again.

5. Docker's port mapping is only mapped to the virtual machine, and port forwarding needs to be set before it can be accessed. Forward port 80 of the virtual machine to 127.0.0.2, so that you can access it using 127.0.0.2 without occupying port 80 of the local machine.
