Docker Desktop Vmmem内存占用过高问题解决方案

内存占用过高原因

主要原因是docker desktop的实现及基于wsl(Windows子系统),相当于在Windows上同时开了一个虚拟机,如果不对wsl的资源进行限制,它将会极大的获取系统资源.所以我们只需要对wsl的最大资源进行限制即可

解决方案

修改wsl配置文件

官方地址

具体配置:

# 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=4GB 

# 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=8GB

# 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

在用户目录创建个.wslconfig文件,即C:\Users\<UserName>\.wslconfig

创建完成后将配置文件内容粘贴进去

[wsl2]
#配置wsl的核心数
processors=2
#配置wsl的内存最大值
memory=512MB
#配置交换内存大小,默认是电脑内存的1/4
swap=8GB
#关闭默认连接以将 WSL 2 本地主机绑定到 Windows 本地主机
localhostForwarding=true
#设置临时文件位置, 默认 %USERPROFILE%\AppData\Local\Temp\swap.vhdx
swapfile=D:\\temp\\wsl-swap.vhdx
