【问题描述】：
过去几个小时我一直在调试我的系统，但我不知道这里发生了什么。
我正在使用一个简单的 docker-compose.yml 文件在我的 Ubuntu 20.04 LTS 系统上启动一个 mariadb 和一个 adminer 实例。
docker-compose.yml：
version: '3'
services:
database:
image: mariadb
restart: always
environment:
MYSQL_DATABASE: feedback
MYSQL_USER: db_user
MYSQL_PASSWORD: password
MYSQL_ROOT_PASSWORD: root
adminer:
image: adminer
restart: always
environment:
ADMINER_DEFAULT_SERVER: database
ports:
- "127.0.0.1:8080:8080"
一位同事对此进行了测试，它在他们的系统上 100% 的运行时间。然而，在我的系统中，过去几个小时内，它只在无数次尝试中成功了两次。
这是 docker-compose 输出：
Creating knowledge-base_database_1 ... done

database_1 | PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !
database_1 | To do so, start the server, then issue the following command:
database_1 |
database_1 | '/usr/bin/mysql_secure_installation'
database_1 |
database_1 | which will also give you the option of removing the test
database_1 | databases and anonymous user created by default. This is
database_1 | strongly recommended for production servers.

database_1 | See the MariaDB Knowledgebase at https://mariadb.com/kb or the
database_1 | MySQL manual for more instructions.

我尝试禁用防火墙、重新安装 docker 和 docker-compose、使用 docker 创建自定义网络而不是使用 docker-compose 的默认网络等。
我还在我的系统上启动了一个已知的工作项目，它产生了相同的结果。我的系统上的某些东西似乎坏了，但我不知道该去哪里找了。
有没有人知道我可以尝试什么来使它正常工作？
