我不能让artifactory用mysql在docker中工作。下面是我得到的错误。
我首先创建一个地方来保存artifactory的文件： # sudo mkdir /opt/artifactory/docker_volume 使用外部mysql示例设置compose文件（使用stack示例也不起作用，因为stack示例从未启动）。
artifactory-oss-mysql.yml：

version: '3'

services:
  artifactory:
    image: docker.bintray.io/jfrog/artifactory-oss:6.1.0
    ports:
      - 8081:8081
    volumes:
      - /opt/artifactory/docker_volume:/var/opt/jfrog/artifactory
      - /opt/artifactory/mysql-connector-java-8.0.11/mysql-connector-java-8.0.11.jar:/var/opt/jfrog/artifactory/tomcat/common/lib/mysql-connector-java-8.0.11.jar
    environment:
      - DB_TYPE=mysql
      - DB_USER=artifactory
      - DB_HOST=mysql
      - DB_PASSWORD=xxx
      - DB_URL=jdbc:mysql://my_sql:3306/artdb?characterEncoding=UTF-8&elideSetAutoCommits=true
    restart: always
    ulimits:
      nproc: 65535
      nofile:
        soft: 32000
        hard: 40000

启动堆栈： # docker stack deploy -c artifactory-oss-mysql.yml artifactory 你会注意到 docker_volume 主人变了，一切都变了。唯一的例外是mysql连接器( /var/opt/jfrog/artifactory/tomcat/common/lib/mysql-connector-java-8.0.11.jar )，保留根所有权。

# ls -al

drwxr-xr-x  5 root root    4096 Jul 17 17:47 .
drwxr-xr-x 16 root root    4096 Jul 17 15:40 ..
drwxr-xr-x  8 1030 1030    4096 Jul 17 17:47 docker_volume

每个子目录都是空的（tomcat中的连接器除外）：

/opt/artifactory/docker_volume # ls -al
