brew install podman
podman machine init

podman machine init --cpus=4 --disk-size=64 --memory=6144
podman machine start podman-machine-default

开启和关闭root 权限

Tips: 切换root 模式前后，相互看不到对方模式下的Images

podman machine set --rootful
podman machine set --rootful=false

podman system connection list                                                                                                                  Name                         URI                                                               Identity                                  Default
podman-machine-default       ssh://core@localhost:62426/run/user/110553204/podman/podman.sock  /Users/wakun/.ssh/podman-machine-default  false
podman-machine-default-root  ssh://root@localhost:62426/run/podman/podman.sock                 /Users/wakun/.ssh/podman-machine-default  true

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 /usr/local/Cellar/podman/4.1.1/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/wakun/.local/share/containers/podman/machine/podman-machine-default/podman.sock'

Podman machine 管理

• 查看创建的虚拟机 podman machine list
• 虚拟机在本地磁盘存储位置: /Users/wakun/.local/share/containers/podman/machine/qemu/podman-machine-default_fedora-coreos-37.20221211.2.0-qemu.x86_64.qcow2x
• 通过 qemu 启动的虚拟机配置 : /Users/wakun/.config/containers/podman/machine/qemu
• 修改虚拟机硬件配置 ：podman machine set --help
• 进入虚拟机，可以sudo 到 root 账号 ：podman machine ssh podman-machine-default

Pull Image 加速

目前DockerHub pull image会限制速度，中科大的mirror 已经暂停外部访问。

通过 Ucloud 容器镜像库进行加速

Link: https://console.ucloud.cn/uhub/uhub/accelerate_image

通过 创建加速任务 创建需要pull 的image mirror。本地login ucloud repo podman login uhub.service.ucloud.cn 之后，就可以pull 对应的 ucloud image mirror

通过阿里云镜像加速下载

• 进入podman machine 内部，修改 /etc/containers/registries.conf 或者 /etc/containers/registries.conf.d/999-podman-machine.conf 配置文件，增加如下

[[registry]]
location = "docker.io"
[[registry.mirror]]
location = "xxx.mirror.aliyuncs.com"

Troubleshooting

Homebrew 没有更新导致下载的qemu 版本低，虚拟机无法启动

一开始本低 Homebrew 没有更新，podman 依赖的 qemu 7.0.0_1 版本过低，这个版本的qemu 有Bug。更新Homebrew 后，https://github.com/Homebrew/homebrew-core/blob/master/Formula/qemu.rb 版本升级到 qemu--7.2.0.monterey.bottle.tar.gz 之后启动正常。Double check 本低的 qemu 版本号: /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/qemu.rb
