Docker 17.12.0-ce内存扩容咨询：Win10 Linux环境仅分配15MB

Hey there! Let's sort out that frustratingly small 15MB memory allocation for your Docker setup on Windows 10's Linux environment. Since you're running Docker 17.12.0-ce and the advanced settings menu doesn't show a 2GB option, here are some solid, no-reinstall ways to bump up the memory:

If your Docker is running on a VirtualBox-backed VM (common with Docker Toolbox), this is the most straightforward fix:

• First, shut down all running containers and the Docker VM:

  docker stop $(docker ps -aq)
  docker-machine stop default
  

• Open VirtualBox, locate the default VM (this is Docker's default virtual machine)
• Right-click it, select Settings -> System -> Motherboard, then set Base Memory to 2048MB (2GB) or your desired amount
• Fire up the Docker VM again and apply the environment variables:

  docker-machine start default
  eval $(docker-machine env default)
  

• Verify the change worked by running:

  docker run --rm busybox free -m
  

If you're running Docker directly within a WSL environment or have access to the daemon config:

• Check if the daemon config file exists at /etc/docker/daemon.json; if not, create it
• Open the file with a text editor and add the memory allocation (set to 2GB here):

  {
    "resources": {
      "memory": "2048m"
    }
  }
  

• Restart the Docker service to apply changes:

  sudo systemctl restart docker
  

• Confirm the new memory limit with:

  docker info | grep Memory
  

If your Docker is using WSL 1 or WSL 2 as its backend:

• Shut down all WSL instances and Docker completely:

  wsl --shutdown
  

• On your Windows system, navigate to your user directory (e.g., C:\Users\YourUsername) and create/edit a file named .wslconfig
• Add these lines to set the memory to 2GB (you can adjust the value as needed):

  [wsl2]
  memory=2GB
  

• Restart WSL and Docker, then check the memory with:

  wsl
  free -m
