我們對于docker-compose并不陌生，它是一個用于編排多個可能相互依賴的容器的工具。

而Podman Compose項目的目標是作為 docker-ompose 的替代品，而不需要對 docker-compose.yaml 文件進行任何修改。

要想使用podman-compose需要先安裝podman，然后安裝podman-compose。

Rocky8下安裝podman：

yum install -y podman

Rocky8下安裝podman-compose，因為podman-compose是基于python開發，可以使用pip來安裝:

pip3 install podman-compose

示例：使用podman-compose部署wordpress

編輯docker-compose.yml文件，內容如下

version: "3.8"
services:
web:
image: wordpress
restart: always
volumes:
- wordpress:/var/www/html
ports:
- 8080:80
environment:
WORDPRESS_DB_HOST: db
WORDPRESS_DB_USER: magazine
WORDPRESS_DB_NAME: magazine
WORDPRESS_DB_PASSWORD: 1maGazine!
WORDPRESS_TABLE_PREFIX: cz
WORDPRESS_DEBUG: 0
depends_on:
- db
networks:
- wpnet
db:
image: mariadb:10.5
restart: always
ports:
- 6603:3306


volumes:
- wpdbvol:/var/lib/mysql


environment:
MYSQL_DATABASE: magazine
MYSQL_USER: magazine
MYSQL_PASSWORD: 1maGazine!
MYSQL_ROOT_PASSWORD: 1maGazine!
networks:
- wpnet
volumes:
wordpress: {}
wpdbvol: {}


networks:
wpnet: {}

為了讓podman拉取鏡像更快，先給它配置個加速器

#mv/etc/containers/registries.conf/etc/containers/registries.conf.bak
# vi /etc/containers/registries.conf ##添加如下內容
unqualified-search-registries = ["docker.io"]


[[registry]]
prefix = "docker.io"
location = "docker.io"


[[registry.mirror]]
location = "hub-mirror.c.163.com"


[[registry.mirror]]
location = "mirror.baidubce.com"


[[registry.mirror]]
location = "f1361db2.m.daocloud.io"


[[registry.mirror]]
location = "ustc-edu-cn.mirror.aliyuncs.com"


[[registry.mirror]]
location = "ghcr.io"

然后就可以啟動wordpress容器啦：

# podman-compose up -d

用起來其實跟docker-compose一樣。
