轻量级 Kubernetes 发行版实践
目录
部署和管理原生 Kubernetes 集群是一项复杂的任务，为了解决这个问题，社区提供了轻量级 Kubernetes 发行版作为解决方案。
Minikube 结合 Podman 实践
Minikube 是一种轻量级的 Kubernetes 实现，可在本地计算机上创建虚拟机并部署仅包含一个节点的简单集群。
Podman 是一个开源的容器运行时工具，它提供与 Docker 相似的功能，但不需要守护进程，并且支持更多的安全特性和 rootless 模式运行。
基础环境
OS: macOS
Architecture: ARM64
Driver: Podman
CPUs: 2
Memory: 2Gi
Disk: 20GiB
Installer: Homebrew
安装使用 Podman
➜ brew install podman
==> Installing dependencies for podman: capstone, dtc, pcre2, gettext, glib, gmp, libtasn1, nettle, p11-kit, openssl@3, libnghttp2, unbound, gnutls, jpeg-turbo, libpng, libslirp, libssh, libusb, lzo, pixman, snappy, vde and qemu
==> podman
➜ podman machine init --cpus 2 --memory 2048 --disk-size 20 --rootful

API forwarding listening on: /Users/damonguo/.local/share/containers/podman/machine/qemu/podman.sock
The system helper service is not installed; the default Docker API socket address can't be used by podman.
If you would like to install it, run the following commands:
sudo /opt/homebrew/Cellar/podman/4.8.1/bin/podman-mac-helper install
podman machine stop; podman machine start
You can still connect Docker API clients by setting DOCKER_HOST using the following command in your terminal session:
export DOCKER_HOST='unix:///Users/damonguo/.local/share/containers/podman/machine/qemu/podman.sock'
Machine "podman-machine-default" started successfully
