JIANCHUJUN opened a new issue #4871:
URL: https://github.com/apache/incubator-dolphinscheduler/issues/4871
**Describe the question**
Hi, I am using docker-compose to deploy Dolphinscheduler (1.3.5, official
release), but I can't connect to MySQL datasource. I tried to use "docker cp"
and copy "mysql-connector-java-5.1.34.jar" into /opt/dolphinscheduler/lib, but
the connection still failed. Do I need to change configuration file elsewhere?
**Which version of DolphinScheduler:**
-[1.3.5, Docker-Compose]
