我试图执行下面的命令。

docker run --name artifactory-host-mysql -e DB_TYPE=mysql -e DB_HOST=my_host_ip -e DB_URL='jdbc:mysql://my_host_ip:3306/some_db?characterEncoding=UTF-8&elideSetAutoCommits=true' -e DB_PORT=3306  -e DB_USER=my_db_user -e DB_PASSWORD=my_passowrd -d -p 8083:8083 --net=host -v /artifactory/mysql-connector-java-5.1.46.jar:/opt/jfrog/artifactory/tomcat/lib/mysql-connector-java-5.1.46.jar artifactory-hostmysql

输出如下

mysql服务已经在主机上运行，端口3306也为tcp打开-netstat的输出-tlnp如下
