计划

我希望我的tomcat服务器能够在单独的容器中连接到我的MySQL服务器.

问题

Tomcat无法连接到MysqL

我使用了wordpress tutorial中有关设置MysqL容器链接的一些细节,并创建了MysqL的链接.

虽然tomcat和MysqL旋转得很好我似乎无法让tomcat能够连接到MysqL,我的本地机器上的设置工作完全没问题.

我试图使用–net：“host”,尽管这不适用于Tomcat,因为它会引发严重的错误.

以前的答案

我可以修复错误的noticed on this post a load虽然我不相信其中任何一个会转换为我的问题,因为我认为这是一个码头工人问题而不是主机问题.

泊坞窗,compose.yml

web:
  image: tomcat:7.0
  container_name: tomcat-container
  ports:
   - "80:8080"
  hostname: docker-tomcat
  volumes:
   - /home/webapps:/usr/local/tomcat/webapps
  links:
   - db
db:
  image: MysqL
  container_name: MysqL-container
  environment:
   MysqL_ROOT_PASSWORD: MysqLpassword1
   MysqL_DATABASE: tracker
  volumes:
   - /home/MysqLDB:/var/lib/MysqL

这是我在tomcat中的Context.xml.
