docker - 无法连接到 wsl 2 上 debian buster 上的 Docker 守护程序

问题描述

我正在尝试在 Windows Subsystem for Linux (WSL) 2 上安装 docker（在 Windows Home build 19033.1 上运行）。我按照https://docs.microsoft.com/en-us/windows/wsl/wsl2-install上的说明安装了 wsl2，并从 Windows Store 安装了 debian，即 debian 10（buster）。它在 wsl 2 上运行，如下所示：

wsl -l -v
NAME STATE VERSION
* Debian Running 2

$ cat /etc/os-release
PRETTY_NAME="Debian GNU/Linux 10 (buster)"
NAME="Debian GNU/Linux"
VERSION_ID="10"
VERSION="10 (buster)"
VERSION_CODENAME=buster
ID=debian
HOME_URL=" https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"

我按照https://linuxconfig.org/how-to-install-docker-on-debian-10-buster-linux的说明安装 docker：

sudo apt install docker.io
sudo docker run hello-world docker
：无法连接到 unix:///var/run/docker.sock 上的 Docker 守护进程。docker 守护进程是否正在运行？

查看docker是否正在运行：

sudo service docker status
[FAIL] Docker 没有运行……失败了！

所以我尝试重新启动docker守护进程：

$ sudo service docker restart
grep: /etc/fstab: No such file or directory
[ ok ] 启动 Docker: docker.

在 SO 上找到另一篇文章说我可以通过发布来解决这个问题：

须藤触摸 /etc/fstab

这似乎有效（不再出现grep错误）：

$ sudo service docker restart
[ ok ] 启动 Docker：docker.

但我仍然遇到同样的问题：

$ sudo docker run hello-world
docker：无法连接到 unix:///var/run/docker.sock 上的 Docker 守护进程。docker 守护进程是否正在运行？

我查看了 docker 日志，里面充满了错误：

有点迷失了这里的问题。希望有人可以建议？

我遵循了下面@sx-tan 的出色建议，他建议遵循https://kind.sigs.k8s.io/docs/user/using-wsl2/#updating-kernel上的说明。这些说明说要发布：

# This assumes Ubuntu or Debian, a different step may be needed for RPM based distributions
sudo apt install build-essential flex bison libssl-dev libelf-dev
git clone --depth 1 https://github.com/microsoft/WSL2-Linux-Kernel.git
cd WSL2-Linux-Kernel
make -j4 KCONFIG_CONFIG=Microsoft/config-wsl
mkdir /mnt/c/linuxtemp
cp arch/x86_x64/boot/bzImage /mnt/c/linuxtemp/

cp不幸的是，这些命令不会产生与该命令所期望的相同的 dir 结构。我没有arch/x86_x64/目录。我确实有一个arch/x86目录，但不包含boot/bzImage：

jamiet@DESKTOP-GA45TGH:/mnt/c/Users/jamie/git/github/microsoft/WSL2-Linux-Kernel$ ls arch/x86/boot/
a20.c       code16gcc.h  cpuflags.h              install.sh      pm.c      string.h      video.c
apm.c       compressed   ctype.h                 main.c          pmjump.S  tools         video.h
bioscall.S  copy.S       early_serial_console.c  Makefile        printf.c  tty.c         video-mode.c
bitops.h    cpu.c        edd.c                   memory.c        regs.c    version.c     video-vesa.c
boot.h      cpucheck.c   genimage.sh             mkcpustr.c      setup.ld  vesa.h        video-vga.c
cmdline.c   cpuflags.c   header.S                mtools.conf.in  string.c  video-bios.c

我遵循了确切的说明，因此只能猜测自从编写了https://kind.sigs.k8s.io/docs/user/using-wsl2/#updating-kernel以来，回购已经发生了变化。如果它有帮助，这里是目录arch：

jamiet@DESKTOP-GA45TGH:/mnt/c/Users/jamie/git/github/microsoft/WSL2-Linux-Kernel$ ls arch/
alpha  arm    c6x    hexagon  Kconfig  microblaze  nds32  openrisc  powerpc  s390  sparc  unicore32  xtensa
arc    arm64  h8300  ia64     m68k     mips        nios2  parisc    riscv    sh    um     x86

仍然希望有人能澄清一下。
