文章目录
简介
Podman是一个无守护进程的开源 Linux 原生工具，旨在使用开放容器倡议 ( OCI )容器和容器映像轻松查找、运行、构建、共享和部署应用程序。Podman 提供了任何使用过 Docker容器引擎的人都熟悉的命令行界面 (CLI) 。大多数用户可以简单地将 Docker 别名为 Podman（别名 docker=podman），没有任何问题。与其他常见的容器引擎（Docker、CRI-O、containerd）类似，Podman 依赖于符合 OCI 的容器运行时（runc、crun、runv 等）与操作系统交互并创建正在运行的容器。这使得 Podman 创建的运行容器与任何其他常见容器引擎创建的容器几乎没有区别。
Podman 控制下的容器可以由 root 或非特权用户运行。Podman 使用libpod库管理整个容器生态系统，包括 pod、容器、容器镜像和容器卷。Podman 专注于帮助您维护和修改 OCI 容器映像的所有命令和功能，例如拉取和标记。它允许您在生产环境中创建、运行和维护这些容器和容器映像。
Podman 服务仅运行在 Linux 平台上，但 Podman 远程 REST API 客户端存在于 Mac 和 Windows 平台上，并且可以通过 ssh 与运行在 Linux 机器或 VM 上的 Podman 服务进行通信。
docker是一个容器引擎，podman也是一个容器引擎

[root@localhost ~]# which podman
/usr/bin/podman
普通用户使用podman的方式
在允许没有root特权的用户运行podman之前，管理员必须需要安装或构件podman并完成以下配置
cgroup V2Linux内核功能允许用户限制普通用户容器可以使用的资源，如果使用cgroup V2启用了运行Podman的Linux发行版，则可能需要更改默认的OCI运行时。某些较旧的版本runc不适用于cgroup V2，必须切换到备用OCI运行时crun。
[root@localhost ~]# yum -y install crun
[root@localhost ~]# rpm -qa|grep crun
crun-1.2-1.module_el8.6.0+954+963caf36.x86_64
可以使用–runtime选项在命令行中打开对cgroup V2的替代OCI运行时支持或者修改containers.conf文件
podman --runtime crun
修改containers.conf文件
[root@localhost ~]# vim /usr/share/containers/containers.conf
# Default OCI runtime
#
#runtime = "crun"
runtime = "crun"
安装slirp4netns
slirp4nets包为普通用户提供一种网络模式，在普通用户环境中使用Podman时，建议使用fuse-overlayfs而不是VFS文件系统，至少需要版本0.7.6以上的才能使用
[root@localhost ~]# dnf -y install slirp4netns fuse-overlayfs ##安装slirp4netns
[root@localhost ~]# rpm -qa|grep slirp4netns
slirp4netns-1.1.8-1.module_el8.6.0+926+8bef8ae7.x86_64
[root@localhost ~]# rpm -qa|grep fuse-overlayfs
fuse-overlayfs-1.7.1-1.module_el8.6.0+926+8bef8ae7.x86_64
配置storage.conf文件
[root@localhost ~]# vim /etc/containers/storage.conf
····省略部分···
# Default Storage Driver, Must be set for proper operation.
driver = "overlay"
····省略部分···
# Path to an helper program to use for mounting the file system instead of mounting it
# directly.
mount_program = "/usr/bin/fuse-overlayfs" #取消注释
····省略部分···
用户的配置文件
三个主要的配置文件是container.conf，storage.conf和registries.conf。用户可以根据需要修改这些文件。
container.conf
Podman读取时,按照循序来了，当前面一位找不到时，就去找下一个
1./usr/share/containers/containers.conf
2./etc/containers/containers.conf
3.$HOME/.config/containers/containers.conf
storage.conf
对于storge.conf则是
1./etc/containers/storage.conf
2.$HOME/.config/containers/storage.conf
在普通用户中/etc/containers/storage.conf的一些字段将被忽略
graphroot=``""`` ``container storage graph ``dir` `(default: ``"/var/lib/containers/storage"``)`` ``Default directory to store all writable content created by container storage programs.` `runroot=``""`` ``container storage run ``dir` `(default: ``"/run/containers/storage"``)`` ``Default directory to store all temporary writable content created by container storage programs.
在普通用户中这些字段默认
graphroot=``"$HOME/.local/share/containers/storage"``runroot=``"$XDG_RUNTIME_DIR/containers"
registries.conf
配置按此顺序读入,这些文件不是默认创建的,可以从/usr/share/containers或复制文件/etc/containers并进行修改。
1./etc/containers/registries.conf
2./etc/containers/registries.d/*
3.HOME/.config/containers/registries.conf
授权文件
podman login 登录，默认授权文件位于中/run/user/0//containers/auth.json
[root@localhost ~]# podman login docker.io
Username: best2001
Password:
Login Succeeded!
[root@localhost ~]# cat /run/user/0/containers/auth.json
{
"auths": {
"docker.io": {
"auth": "YmVzdDIwMDE6bGl1cWlhbmcyMDAxNzI="
}
}
}
启用用户命名空间
文件中指定了系统上允许的用户名称空间的数量/proc/sys/user/max_user_namespaces。在大多数Linux平台上，这是默认设置的，无需调整。然而，在RHEL7机，具有根特权的用户可能需要通过使用该命令，为了设置为合理值:Ⅰsysctl
/etc/subuid和/etc/subgid配置
podman要求运行它的用户在/etc/subuid和/etc/subgid文件中列出一系列UID，shadow-utils或newuid包需要提供这些文件
[root@localhost ~]# rpm -qa| grep shadow-util
shadow-utils-4.6-12.el8.x86_64
对于将被允许创建容器，更新每一个用户/etc/subuid，并/etc/subgid 与看起来像以下字段用户。请注意，每个用户的值必须是唯一的。如果存在重叠，用户就有可能使用另一个用户的命名空间，并且他们可能会破坏它。
[root@localhost ~]# useradd test
[root@localhost ~]# cat /etc/subuid
test:100000:65536
[root@localhost ~]# cat /etc/subgid
test:100000:65536
该文件的格式为USERNAME:UID:RANGE
- 在/etc/passwd或个体pwent中列出用户名
- 为用户分配的初始UID
- 为用户分配的UID范围的大小
