1.拉取测试镜像
[root@localhost ~]# podman pull busybox Resolved "busybox" as an alias (/etc/containers/registries.conf.d/000-shortnames.conf) Trying to pull docker.io/library/busybox:latest... Getting image source signatures Copying blob 5cc84ad355aa done Copying config beae173cca done Writing manifest to image destination Storing signatures beae173ccac6ad749f76713cf4440fe3d21d1043fe616dfbe30775815d1d0f6a
2.配置加速器
[root@localhost ~]# cd /etc/containers/ [root@localhost containers]# ls certs.d policy.json registries.conf.d storage.conf oci registries.conf registries.d [root@localhost containers]# vim registries.conf unqualified-search-registries = ["docker.io"] [[registry]] prefix = "docker.io" location = "onmth88j.mirror.aliyuncs.com" //直接到我们自己的阿里云账号上寻找地址，并且不需要http：// 直接写入地址
3.创建运行一个容器
[root@localhost ~]# podman run --name test -dit busybox [root@localhost ~]# podman ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES fb25aff33803 docker.io/library/busybox:latest sh 8 seconds ago Up 7 seconds ago test
4.创建容器自启动文件
//如果想每次重启都会删除旧容器启动一个新的容器，则可以使用--new选项 [root@localhost ~]# podman generate systemd --files --name test --new /root/container-test.service
5.将生成的文件放到/usr/lib/systemd/system/目录中，并且重启使其生效
[root@localhost ~]# ls anaconda-ks.cfg container-test.service [root@localhost ~]# mv container-test.service /usr/lib/systemd/system/ [root@localhost ~]# systemctl daemon-reload [root@localhost ~]# setenforce 0
6.修改selinux并且设置开机自启
[root@localhost ~]# vim /etc/selinux/config SELINUX=disabled [root@localhost ~]# systemctl enable --now container-test.service Created symlink /etc/systemd/system/multi-user.target.wants/container-test.service → /usr/lib/systemd/system/container-test.service. Created symlink /etc/systemd/system/default.target.wants/container-test.service → /usr/lib/systemd/system/container-test.service.
7.重启测试效果
//重启后容器依旧处于启动状态，则设置开机自启成功 [root@localhost ~]# reboot 连接断开 连接成功 Last login: Tue May 10 14:44:03 2022 from 192.168.12.1 [root@localhost ~]# podman ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES ef6663d675b8 docker.io/library/busybox:latest sh 58 seconds ago Up 55 seconds ago test
