关于docker占用内存太多的问题

问题及解决方法

开发中使用docker然后内存占用贼大,直接导致电脑卡死,找到了一个方法可以将内存降下来一点,以后还是要加内存的

方法

1. 打开这个文件夹新建一个文件.wslconfig,这个文件是不存在的,需要新建
   
2. 在文件中添加配置信息

# 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=2GB 
 
# Sets the VM to use two virtual processors
processors=2
 
# Specify a custom Linux kernel to use with your installed distros. The default kernel used can be found at https://github.com/microsoft/WSL2-Linux-Kernel
# kernel=C:\\temp\\myCustomKernel
 
# Sets additional kernel parameters, in this case enabling older Linux base images such as Centos 6
# kernelCommandLine = vsyscall=emulate
 
# Sets amount of swap storage space to 8GB, default is 25% of available RAM
swap=4GB
 
# Sets swapfile path location, default is %USERPROFILE%\AppData\Local\Temp\swap.vhdx
# swapfile=C:\\temp\\wsl-swap.vhdx
 
# Disable page reporting so WSL retains all allocated memory claimed from Windows and releases none back when free
# pageReporting=false
 
# Turn off default connection to bind WSL 2 localhost to Windows localhost
localhostforwarding=true
 
# Disables nested virtualization
# nestedVirtualization=false
 
# Turns on output console showing contents of dmesg when opening a WSL 2 distro for debugging
# debugConsole=true

3. 管理员的方式打开终端
   
4. 输入命令

wsl --shutdown

5. 重启docker即可
