Question

我尝试按照https://docs.docker.com/get-started/part3/上的说明进行操作，但将其更改为单个节点MariaDB数据库。我正在使用看起来像这样的docker-compose.yml文件......

version: "3"
services:
  database:
    image: mariadb:latest
    environment:
      MYSQL_DATABASE: jeesample
      MYSQL_USER: jeeuser
      MYSQL_PASSWORD: password
    networks:
    - webnet
    ports:
    - "3307:3306"
networks: 
  webnet:

然后我用

开始

docker stack deploy -c docker-compose.yml jeesample

然而，当我查看docker stack ps jeesample时，我得到以下内容：

ID            NAME                      IMAGE           NODE  DESIRED STATE  CURRENT STATE                   ERROR                      PORTS

ma1gkri9os14   \_ jeesample_database.1  mariadb:latest  moby  Shutdown       Failed 37 seconds ago           "task: non-zero exit (1)"

尝试使用jdbc:mariadb://localhost:3307/jeesample从本地计算机上的SQL客户端连接到它失败，因为我无法连接

诊断此问题的一种方法是查看日志。要获取日志，请执行docker ps以获取容器列表，然后docker logs -f <container ID>以获取日志结果。由于它是在docker-compose上，容器可能会在一段时间后消失，因此-f选项会保持连接直到它终止。

要解决日志说root用户需要密码的问题，我只需要添加

MYSQL_RANDOM_ROOT_PASSWORD: "true"

虽然还有其他选择

MYSQL_ROOT_PASSWORD: "blah" // visible on source
MYSQL_ALLOW_EMPTY_PASSWORD: "yes" // not recommended

使用docker堆栈在docker容器中运行MariaDB
