在WSL中使用Docker

2 min read

在windows中使用docker有多种方式：

  • docker WIN10 desktop

  • WSL

本文主要介绍在WSL中使用docker

前提条件

  • Windows 10 Version 1803以上(支持cgroups)

  • Ubuntu for WSL 16.0.4 LTS(WSL支持的最新版本)

  • Docker 17.09

安装WSL

install WSL

WSL 命令行和默认 shell

cmd:\>wsl
wubigo:/tmp/docker-desktop-root/mnt/host/d/code#/etc# cat /etc/wsl.conf
[automount]
root = /mnt/host
crossDistro = true
options = "metadata"

WSL DOCKER磁盘卷路径

cmd:\>docker volume inspect edgex_consul-config
[
    {
        "CreatedAt": "2022-03-07T08:04:34Z",
        "Driver": "local",
        "Labels": {
            "com.docker.compose.project": "edgex",
            "com.docker.compose.version": "2.2.3",
            "com.docker.compose.volume": "consul-config"
        },
        "Mountpoint": "/var/lib/docker/volumes/edgex_consul-config/_data",
        "Name": "edgex_consul-config",
        "Options": null,
        "Scope": "local"
    }
]

\\wsl$\docker-desktop-data\version-pack-data\community\docker\volumes\

安装Ubuntu for WSL 16.0.4 LTS

install ubuntu in WSL

安装DOCKER

  • 启动ubuntu in WSL(以管理员身份运行)

    c:\>wsl -d Ubuntu-16.04

  • 安装docker

    $ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
$ sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
$ sudo apt-get install docker-ce=17.09.0~ce-0~ubuntu
$ sudo usermod -aG docker $USER

  • 启动docker服务

/usr/local/sbin/start_docker.sh

#!/usr/bin/env bash
sudo cgroupfs-mount
sudo service docker start

在系统启动的时候运行docker服务

在控制面版\管理工具\计划任务创建任务

操作的参数如下：

-c "sudo /bin/sh /usr/local/sbin/start_docker.sh"

备份WSL

在备份前保存并关闭所有的WSL进程，否则正在运行的进程被强行关闭

c:\>wsl -l
c:\>wsl --export Ubuntu-16.04 Ubuntu-16.wsl.export.tar

升级linux

d:\code\dapp>wsl -l -v
  NAME                   STATE           VERSION
* Ubuntu                 Running         1
  docker-desktop         Running         2
  docker-desktop-data    Running         2

升级Ubuntu 从WSL 1 到2

wsl --set-version Ubuntu 2

d:\code\dapp>wsl -l -v
  NAME                   STATE           VERSION
* Ubuntu                 Stopped         2
  docker-desktop         Running         2
  docker-desktop-data    Running         2

WSL localhost connection refused

运行之前先备份/etc/hosts

wsl2-ubuntu-map-win-localhost.sh

nameserver=$(grep -m 1 nameserver /etc/resolv.conf | awk '{print $2}')   # find nameserver
[ -n "$nameserver" ] || "unable to find nameserver" || exit 1            # exit immediately if nameserver was not found
echo "##### nameserver found: '$nameserver'"
localhost_entry=$(grep -v "127.0.0.1" /etc/hosts | grep "\slocalhost$")  # find localhost entry excluding 127.0.0.1
if [ -n "$localhost_entry" ]; then                                       # if localhost entry was found
    echo "##### localhost entry found: '$localhost_entry'"
    sed -i "s/$localhost_entry/$nameserver localhost/g" /etc/hosts       # then update localhost entry with the new $nameserver
else                                                                     # else if entry was not found
    echo "##### localhost entry not found"
    echo "$nameserver localhost" >> /etc/hosts                           # then append $nameserver mapping to localhost
fi
cat /etc/hosts

静态IP

WSL-ip.bat

wsl -d Ubuntu -u root ip addr add 192.168.50.16/24 broadcast 192.168.50.255 dev eth0 label eth0:1

netsh interface ip add address "vEthernet (WSL)" 192.168.50.88 255.255.255.0
