Rancher Desktop虚拟机
Rancher Desktop 实际上是使用 Lima: Linux Machines 虚拟机来实现 macOS 上运行 Docker 以及 Kubernetes 的。也就是说，一旦使用 Rancher Desktop 跑起来 Kubernetes ，系统中必然有一个虚拟机:
如果是macOS 13 及以后的系统，则可以使用
VZ虚拟化(即 Apple Virtualization )如果是macOS 13 之前的系统，则必须使用 QEMU 虚拟化
那么，如何进入 Lima: Linux Machines 提供的这个虚拟机呢？
rdctl
Rancher Desktop 提供了一个官方工具 rdctl 可以简便地进入虚拟机:
通过
rdctl 进入 Lima 虚拟机rdctl shell
此时会看到shell提示符:
进入
lima-rancher-desktop 虚拟机的提示符lima-rancher-desktop:/Applications/Rancher Desktop.app/Contents/Resources/resources/darwin/lima/bin$
检查当前用户id可以看到，原来进入
Rancher Desktop虚拟机后用户是lima:
用户身份是
lima# id 显示
uid=501(lima) gid=1000(lima) groups=102(docker),1000(lima)
检查内核以及运行环境(
uname -a):
uname -a 显示输出Linux lima-rancher-desktop 6.6.65-0-virt #1-Alpine SMP PREEMPT_DYNAMIC 2024-12-12 12:13:04 x86_64 Linux
检查虚拟机操作系统版本(
cat /etc/os-release)
可以看到运行的是一个
Alpine Linux 虚拟机NAME="Alpine Linux"
ID=alpine
VERSION_ID=3.20.3
PRETTY_NAME="Alpine Linux v3.20"
HOME_URL="https://alpinelinux.org/"
BUG_REPORT_URL="https://gitlab.alpinelinux.org/alpine/aports/-/issues"
BUILD_ID="v0.2.41.rd3"
VARIANT_ID="rd"
检查磁盘(
sudo df -h)需要使用root身份，因为当前运行的 Kubernetes 容器挂载存储都需要root权限:
sudo df -h 输出Filesystem Size Used Available Use% Mounted on
