Podman怎么设置开机自启动

podman无守护进程无法像docker一样设置开机自启动

1. 环境查看
   系统环境

# lsb_release -a
No LSB modules are available.
Distributor ID:Ubuntu
Description:Ubuntu 22.04.4 LTS
Release:22.04
Codename:jammy
# uname -a
Linux Ubuntu22K8SMaster003151 6.8.0-90-generic #91~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Thu Nov 20 15:20:45 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

软件环境

2. 单镜像
   启动一个nginx命名为my_nginx

podman  run -d -p 80:80 --privileged --name my_nginx nginx

使用podman自带命令生成systemctl配置文件

podman  generate systemd --name my_nginx --new --restart-policy=always > my_nginx.service

查看配置文件

# cat my_nginx.service 
# container-my_nginx.service
# autogenerated by Podman 3.4.4
# Tue Feb  3 10:19:24 CST 2026[Unit]
Description=Podman container-my_nginx.service
Documentation=man:podman-generate-systemd(1)
Wants=network-online.target
After=network-online.target
RequiresMountsFor=%t/containers[Service]
Environment=PODMAN_SYSTEMD_UNIT=%n
Restart=always
TimeoutStopSec=70
ExecStartPre=/bin/rm -f %t/%n.ctr-id
ExecStart=/usr/bin/podman run --cidfile=%t/%n.ctr-id --cgroups=no-conmon --rm --sdnotify=conmon --replace -d -p 80:80 --name my_nginx nginx
ExecStop=/usr/bin/podman stop --ignore --cidfile=%t/%n.ctr-id
ExecStopPost=/usr/bin/podman rm -f --ignore --cidfile=%t/%n.ctr-id
Type=notify
NotifyAccess=all[Install]
WantedBy=default.target

复制到目录

cp my_nginx.service /usr/lib/systemd/system/

设置开机自启动

systemctl  systemctl daemon-reload
systemctl enable my_nginx
systemctl start my_nginx
systemctl status my_nginx

设置好之后可实现开机自启动podman镜像

3. docker-compose.yml
   如果是docker-compose配置文件启动的呢
   docker-compose.yml配置文件

# cat /root/nginx/docker-compose.yml 
version: "3.9"services:nginx:image: nginx:latest      # 使用最新的官方 Nginx 镜像container_name: nginx_serverports:- "80:80"              # 映射本地 80 端口到容器 80 端口

设置配置文件即可

# cat /usr/lib/systemd/system/podman-compose.service 
[Unit]
Description=Podman Compose for Your Project
After=network-online.target
Wants=network-online.target[Service]
Type=oneshot
RemainAfterExit=yes
# 工作目录放置docker-compose.yml配置文件
WorkingDirectory=/root/nginx
ExecStart=/usr/bin/podman-compose -f docker-compose.yml up -d
ExecStop=/usr/bin/podman-compose -f docker-compose.yml down[Install]
WantedBy=default.target

设置开机自启动

systemctl daemon-reload
systemctl enable my_nginx
systemctl start my_nginx
systemctl status my_nginx
