我试图运行一个测试WordPress博客使用无根的Podman containers。
我尝试了这些教程的许多变体：
https://www.linuxwave.info/2020/12/installing-wordpress-using-podman.html
https://www.linkedin.com/pulse/podman-vs-docker-deploying-wordpress-application-kritik-sachdeva
它总是结束在WordPress通信（显示在网站上，而不是CLI）Error establishing a database connection。
我正在使用VPS / Ubuntu 22.04。让我向您展示一下我的配置：

podman pod create --name myblog --publish 8080:80

podman run --detach --pod myblog \
-e MYSQL_ROOT_PASSWORD=1234 \
-e MYSQL_DATABASE=mywpdb \
-e MYSQL_USER=mywpuser \
-e MYSQL_PASSWORD=1234 \
--name mywpdb docker.io/library/mysql:8

podman run --detach --pod myblog \
-e WORDPRESS_DB_HOST=mywpdb:3306 \
-e WORDPRESS_DB_NAME=mywpdb \
-e WORDPRESS_DB_USER=mywpuser \
-e WORDPRESS_DB_PASWORD=1234 \
--name mywp docker.io/library/wordpress:6.0

容器已启动并运行

ubuntu@vps:~$ podman ps -a

Pod看起来正常：

ubuntu@vps:~$ podman pod inspect myblog

Mysql正在运行

ubuntu@vps:~$ podman logs mywpdb
2022-11-11T20:28:28.722895Z 0 [System] [MY-010931] [Server] /usr/sbin/mysqld: ready for connections. Version: '8.0.31'  socket: '/var/run/mysqld/mysqld.sock'  port: 3306  MySQL Community Server - GPL.

我觉得wordpress容器和mysql容器之间的通信有问题，但是我试了很多方法都没能调试出来，请提示我如何调试这个问题。

编辑：

我设法连接，但访问被拒绝：我使用了podman网络教程中的想法

podman run --detach \
-e MYSQL_ROOT_PASSWORD=1234 \
-e MYSQL_DATABASE='mywpdb' \
-e MYSQL_USER='mywpuser' \
-e MYSQL_PASSWORD='1234' \
-p 6969:3306 \
--name mywpdb \
docker.io/library/mariadb:10

podman run --detach \
-e WORDPRESS_DB_HOST='12.12.12.12:6969' \
-e WORDPRESS_DB_NAME='mywpdb' \
-e WORDPRESS_DB_USER='mywpuser' \
-e WORDPRESS_DB_PASWORD='1234' \
-e WORDPRESS_DEBUG=1 \
-p 8080:80 \
--name mywp \
docker.io/library/wordpress:6.0

现在它结束在mariadb拒绝连接。

2022-11-11 21:50:29 9 [Warning] Access denied for user 'mywpuser'@'10.0.2.100' (using password: YES)

我得进一步调查
