Hi! I'm following the [guide regarding the remote debug](https://www.jetbrains.com/help/idea/run-and-debug-a-spring-boot-application-using-docker-compose.html) and I couldn't run the sample with preconfigured `docker-compose-debug.yml` file. Every time inside the `app` logs appears error related to the connection with MySQL db: ```text 2021-09-04T16:02:54.951246200Z 2021-09-04T16:02:54.951300200Z . ____ _ __ _ _ 2021-09-04T16:02:54.951308300Z /\\ / ___'_ __ _ _(_)_ __ __ _ \ \ \ \ 2021-09-04T16:02:54.951315200Z ( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \ 2021-09-04T16:02:54.951321000Z \\/ ___)| |_)| | | | | || (_| | ) ) ) ) 2021-09-04T16:02:54.951335400Z ' |____| .__|_| |_|_| |_\__, | / / / / 2021-09-04T16:02:54.951355900Z =========|_|==============|___/=/_/_/_/ 2021-09-04T16:02:54.952548900Z :: Spring Boot :: (v2.0.2.RELEASE) 2021-09-04T16:02:54.952582200Z 2021-09-04T16:02:55.132758000Z 2021-09-04 16:02:55.128 INFO 1 --- [ main] com.example.demo.DemoApplication : Starting DemoApplication v0.0.1-SNAPSHOT on ac8c55bea244 with PID 1 (/project/target/demo-0.0.1-SNAPSHOT.jar started by root in /) 2021-09-04T16:02:55.134419000Z 2021-09-04 16:02:55.133 INFO 1 --- [ main] com.example.demo.DemoApplication : No active profile set, falling back to default profiles: default 2021-09-04T16:02:55.311397200Z 2021-09-04 16:02:55.310 INFO 1 --- [ main] ConfigServletWebServerApplicationContext : Refreshing org.springframework.boot.web.servlet.context.AnnotationConfigServletWebServerApplicationContext@2db0f6b2: startup date [Sat Sep 04 16:02:55 UTC 2021]; root of context hierarchy 2021-09-04T16:02:57.501467200Z 2021-09-04 16:02:57.501 INFO 1 --- [ main] trationDelegate$BeanPostProcessorChecker : Bean 'org.springframework.transaction.annotation.ProxyTransactionManagementConfiguration' of type [org.springframework.transaction.annotation.ProxyTransactionManagementConfiguration$$EnhancerBySpringCGLIB$$91522659] is not eligible for getting processed by all BeanPostProcessors (for example: not eligible for auto-proxying) 2021-09-04T16:02:58.023027600Z 2021-09-04 16:02:58.022 INFO 1 --- [ main] o.s.b.w.embedded.tomcat.TomcatWebServer : Tomcat initialized with port(s): 8080 (http) 2021-09-04T16:02:58.073736200Z 2021-09-04 16:02:58.073 INFO 1 --- [ main] o.apache.catalina.core.StandardService : Starting service [Tomcat] 2021-09-04T16:02:58.073884700Z 2021-09-04 16:02:58.073 INFO 1 --- [ main] org.apache.catalina.core.StandardEngine : Starting Servlet Engine: Apache Tomcat/8.5.31 2021-09-04T16:02:58.091702600Z 2021-09-04 16:02:58.091 INFO 1 --- [ost-startStop-1] o.a.catalina.core.AprLifecycleListener : The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: [/usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib] 2021-09-04T16:02:58.227289200Z 2021-09-04 16:02:58.226 INFO 1 --- [ost-startStop-1] o.a.c.c.C.[Tomcat].[localhost].[/] : Initializing Spring embedded WebApplicationContext 2021-09-04T16:02:58.227624500Z 2021-09-04 16:02:58.227 INFO 1 --- [ost-startStop-1] o.s.web.context.ContextLoader : Root WebApplicationContext: initialization completed in 2923 ms 2021-09-04T16:02:59.465554400Z 2021-09-04 16:02:59.465 INFO 1 --- [ost-startStop-1] o.s.b.w.servlet.ServletRegistrationBean : Servlet dispatcherServlet mapped to [/] 2021-09-04T16:02:59.474589300Z 2021-09-04 16:02:59.474 INFO 1 --- [ost-startStop-1] o.s.b.w.servlet.FilterRegistrationBean : Mapping filter: 'characterEncodingFilter' to: [/*] 2021-09-04T16:02:59.475915000Z 2021-09-04 16:02:59.475 INFO 1 --- [ost-startStop-1] o.s.b.w.servlet.FilterRegistrationBean : Mapping filter: 'hiddenHttpMethodFilter' to: [/*] 2021-09-04T16:02:59.476181300Z 2021-09-04 16:02:59.475 INFO 1 --- [ost-startStop-1] o.s.b.w.servlet.FilterRegistrationBean : Mapping filter: 'httpPutFormContentFilter' to: [/*] 2021-09-04T16:02:59.476985200Z 2021-09-04 16:02:59.476 INFO 1 --- [ost-startStop-1] o.s.b.w.servlet.FilterRegistrationBean : Mapping filter: 'requestContextFilter' to: [/*] 2021-09-04T16:02:59.477466100Z 2021-09-04 16:02:59.476 INFO 1 --- [ost-startStop-1] o.s.b.w.servlet.FilterRegistrationBean : Mapping filter: 'httpTraceFilter' to: [/*] 2021-09-04T16:02:59.478608300Z 2021-09-04 16:02:59.478 INFO 1 --- [ost-startStop-1] o.s.b.w.servlet.FilterRegistrationBean : Mapping filter: 'webMvcMetricsFilter' to: [/*] 2021-09-04T16:02:59.627790200Z 2021-09-04 16:02:59.623 INFO 1 --- [ main] com.zaxxer.hikari.HikariDataSource : HikariPool-1 - Starting... 2021-09-04T16:02:59.855026300Z Sat Sep 04 16:02:59 UTC 2021 WARN: Establishing SSL connection without server's identity verification is not recommended.

Change base image inside the Dockerfiles. 2. Use `mysql:5.7.35` instead of your custom one. Because of that we have to add some SQL scripts to populate db schema. 3. Add change in db url within `application.properties` file. My question is: 1. Is there a way to make this working with current master version? 2. Is there a way to create a PR with my changes and merged them with master? At this moment I forked your repo and added a new branch to mine ([link is here](https://github.com/tomaszkyc/SpringBootDockerDemoDebug/tree/feature/adjust-container-configuration)) Please let me know. All the best, Tomasz
