wsl2下Docker拉取镜像很慢的最快解决办法

在windows用户目录下创建一个叫.wslconfig的文件：

文件内容如下：

# Settings apply across all Linux distros running on WSL 2
 [wsl2]
 
 # Limits VM memory to use no more than 4 GB, this can be set as whole numbers using GB or MB
 memory=8GB # 根据你电脑配置来
 
 # Sets the VM to use two virtual processors
 processors=4 # 根据你电脑配置来
 
 # Sets amount of swap storage space to 8GB, default is 25% of available RAM
 swap=8GB # 根据你电脑配置来
 
 # Sets swapfile path location, default is %USERPROFILE%\AppData\Local\Temp\swap.vhdx
 swapfile=D:\\WSL\\wsl-swap.vhdx
 
 # Turn off default connection to bind WSL 2 localhost to Windows localhost
 localhostforwarding=true

然后重新打开wsl，再用hdocker拉镜像，快的起飞。
