+![PODMAN logo](../../logo/podman-logo-source.svg)
+
+Podman是由libpod库提供一个实用的程序，可以被用于创建和管理容器。
+
+下面的教程会教你如何启动 Podman 并使用 Podman 执行一些基本的命令。
+
+如果你正在使用 Mac 或者 Windows
+，你应该先查看[Mac 和 Windows 使用说明](https://github.com/containers/podman/blob/master/docs/tutorials/mac_win_client.md)来设置 Podman
+远程客户端。
+
+**注意**：示例中所有命令皆以非 root 的用户运行，必要的时候通过 `sudo` 命令来获取 root 权限。
+
+## 安装Podman
+
+安装或者编译 Podman ，请参照[安装说明](https://github.com/containers/podman/blob/master/install.md)。
+
+## 熟悉podman
+
+### 运行一个示例容器
+
+这个示例容器会运行一个简单的只有主页的 httpd 服务器。
+
+```console
+podman run -dt -p 8080:8080/tcp -e HTTPD_VAR_RUN=/run/httpd -e HTTPD_MAIN_CONF_D_PATH=/etc/httpd/conf.d \
+ -e HTTPD_MAIN_CONF_PATH=/etc/httpd/conf \
+ -e HTTPD_CONTAINER_SCRIPTS_PATH=/usr/share/container-scripts/httpd/ \
+ registry.fedoraproject.org/f29/httpd /usr/bin/run-httpd
+```
+
+因为命令中的 *-d* 参数表明容器以 "detached" 模式运行，所以 Podman 会在容器运行后打印容器的 ID。
+
+注意为了访问这个 HTTP 服务器，我们将使用端口转发。成功运行需要 slirp4netns 的 v0.3.0+ 版本。
+
+Podman 的 *ps* 命令用于列出正在创建和运行的容器。
+
+```console
+podman ps
+```
+
+**注意**：如果为 *ps* 命令添加 *-a* 参数，Podman 将展示所有的容器。
+
+### 查看正在运行的容器
+
+你可以 "inspect" (查看)一个正在运行的容器的元数据以及其他详细信息。我们甚至可以使用 inspect 的子命令查看分配给容器的 IP 地址。由于容器以非 root 模式运行，没有分配 IP 地址，inspect 的输出会是 "
+none" 。
+
+```console
+podman inspect -l | grep IPAddress\":
+ "SecondaryIPAddresses": null,
+ "IPAddress": "",
+```
+
+**注意**：*-l* 参数是**最近的容器**的指代，你也可以使用容器的ID 代替 *-l*
+
+### 测试httpd服务器
+
+由于我们没有容器的 IP 地址，我们可以使用 curl 测试主机和容器之间的网络通信。下面的命令应该显示我们的容器化 httpd 服务器 的主页。
+
+```console
+curl http://localhost:8080
+```
+
+### 查看容器的日志
+
+你也可以使用 podman 查看容器的日志
+
+```console
+podman logs --latest
+10.88.0.1 - - [07/Feb/2018:15:22:11 +0000] "GET / HTTP/1.1" 200 612 "-" "curl/7.55.1" "-"
+10.88.0.1 - - [07/Feb/2018:15:22:30 +0000] "GET / HTTP/1.1" 200 612 "-" "curl/7.55.1" "-"
+10.88.0.1 - - [07/Feb/2018:15:22:30 +0000] "GET / HTTP/1.1" 200 612 "-" "curl/7.55.1" "-"
+10.88.0.1 - - [07/Feb/2018:15:22:31 +0000] "GET / HTTP/1.1" 200 612 "-" "curl/7.55.1" "-"
+10.88.0.1 - - [07/Feb/2018:15:22:31 +0000] "GET / HTTP/1.1" 200 612 "-" "curl/7.55.1" "-"
+```
+
+### 查看容器中的进程pid
+
+你可以使用 *top* 命令查看容器中 httpd 的 pid
+
+```console
+podman top <container_id>
+ UID PID PPID C STIME TTY TIME CMD
+ 0 31873 31863 0 09:21 ? 00:00:00 nginx: master process nginx -g daemon off;
+ 101 31889 31873 0 09:21 ? 00:00:00 nginx: worker process
+```
+
+### 设置容器的检查点
+
+设置检查点会在停止容器的同时把容器中所有进程的状态写入磁盘。
+
+有了它，容器后续可以被恢复，并在与检查点完全相同的时间点继续运行。 这个功能需要在系统上安装 CRIU 的 3.11+ 版本。
+
+这个功能不支持非 root 模式，因此，如果你想尝试使用它，你需要使用 sudo 方式重新创建容器。
+
+设置容器检查点请使用：
+
+```console
+sudo podman container checkpoint <container_id>
+```
+
+### 恢复容器
+
+恢复容器只能在以前设置过检查点的容器上使用。恢复的容器会在与设置检查点时完全相同的时间点继续运行。
+
+恢复容器请使用：
+
+```console
+sudo podman container restore <container_id>
+```
+
+恢复之后。容器会像设置检查点之前一样回复请求
+
+```console
+curl http://<IP_address>:8080
+```
+
+### 迁移容器
+
+为了将容器从一个主机上热迁移到另一个主机，容器可以在在源系统上创建检查点，传输到目的系统，然后再在目的系统上恢复。
+为了便于传输容器的检查点，可以将其存储在一个指定的输出文件中。
+
+在源系统上：
+
+```console
+sudo podman container checkpoint <container_id> -e /tmp/checkpoint.tar.gz
+scp /tmp/checkpoint.tar.gz <destination_system>:/tmp
+```
+
+在目标系统上：
+
+```console
+sudo podman container restore -i /tmp/checkpoint.tar.gz
+```
+
+恢复之后，容器会像设置检查点之前一样回复请求。这时，容器会在目标系统上继续运行。
+
+```console
+curl http://<IP_address>:8080
+```
+
+### 停止容器
+
+停止 httpd 容器
+
+```console
+podman stop --latest
+```
+
+你还可以使用 *ps* 命令检查一个或多个容器的状态，在这个例子中，我们使用 *-a* 参数列出所有的容器。
+
+```console
+podman ps -a
+```
+
+### 移除容器
+
+移除 httpd 容器
+
+```console
+podman rm --latest
+```
+
+你可以使用 *podman ps -a* 验证容器的删除。
+
+## 集成测试
+
+在环境中如何设置并运行集成测试请查看集成测试的[自述页面](../../test/README.md)
+
+## 更多信息
+
+有关podman 和它的子命令的更多信息请查看 podman 的[自述页面](../../README.md#commands)
