У меня есть приложение dropwizard и докер-контейнер, работающий с моей базой данных mysql.
Я хочу создать Docker-контейнер с моим проектом dropwizard и перенести базу данных с помощью файла config.yml.
Я создал свою собственную сеть - mynet.
Сначала я запускаю контейнер mysql с помощью этой команды:
docker run --name mysql -e MYSQL_ROOT_PASSWORD=root -e MYSQL_DATABASE=wrapper --network mynet mysql:latest
Затем на хосте я запускаю mvn clean install для создания .jar и запускаю контейнер с jar-файлом и скопированными файлами config.yml.
Я запускаю контейнер dropwizard:
docker run -it --network mynet -v $(pwd)/config.yml:/ideaDB/config.yml -p 9004:9004 -p 9005:9005 dropwizard-ideadb sh
и запустить:
java -jar ideadb-SNAPSHOT.jar db migrate config.yml
но я получаю следующую ошибку:
com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

Это мой файл config.yml:
defaultName: Stranger
defaultEmptyResponse: No Data Received
server:
applicationConnectors:
- type: http
port: 9004
adminConnectors:
- type: http
port: 9005
# Database settings.
database:
# the name of the JDBC driver
driverClass: com.mysql.jdbc.Driver
# the username
user: root
# the password
password: root
# the JDBC URL; the database is called tmms
url: jdbc:mysql://mysql:3306/wrapper
swagger:
resourcePackage: ideadb
В URL mysql - это имя моего запущенного контейнера mysql.
Каким должен быть правильный URL в файле config.yml для подключения к mysql?
