Spring boot container can't connect to mysql container [duplicate]

How to communicate between Docker containers via "hostname"
(5 answers)
Closed 6 months ago.
I am trying to containerize a Spring Boot application. The application uses JPA, so in order to run the app, it needs to be connected to a db.
I ran the application locally and successfully connected to a MySQL I had running in a container. However, when I tried running the application container, it was unable to connect to the mysql container.
What I've tried:
In application.properties
Changed spring.datasource.url hostname from localhost to mysql-server (mysql container name)
Added SPRING_DATASOURCE_URL env to docker-compose.yml
Manually build both sql and application containers and connected them to a network
Included depends_on dependency to backend container definition
And a lot more that I can't remember at the moment but will include when they come to me.
Anyways, I can't figure out what I'm missing so any help on this issue would be greatly appreciated.

Error when executing spring sample for camunda 8 platform

I am a newbie trying to execute the spring sample for camunda 8 platform. I have the camunda 8 platform running locally using this docker-compose file. Attached is the screenshot of the local docker ps command.
After cloning the project I have renamed the application.local.properties to application.properties so that the application could connect to the local zeebe cluster (and I deleted the existing application.properties that contained cloud properties) but when I execute the ProcessApplication class I get an error "org.springframework.context.ApplicationContextException: Failed to start bean ‘zeebeClientLifecycle’
Below is the detailed error trace. I am kind of surprised that an out-of-the-box example isn't working out. Could someone guide me on troubleshooting this further?

Thanks.

The issue got resolved after renaming the application.properties file to application.yaml file. The application started successfully. Infact after the application started I could revert back to properties from yaml and it still worked.
Strange issue.

How to run SpringBoot app as non-root user on Debian?

Using Debian 10.
I am trying to run SpringBoot app.jar application i made on a server as non-root user.
I created new user called SpringBootApp.
Application is supposed to run on 443 port.
I changed owned of this .jar file to SpringBootApp and changed permissions to 770 with these commands:
chown springbootapp app.jar
chmod 770 app.jar
However while trying to start application as this user, I get this exception: java.net.BindException: "permission denied". What other permissions do i need to change to run it as non-root user?
The way i run application: java -jar app.jar
Output:
Application run failed

With a root user, there is no problem.

Which port is your application configured to run on?
The BindException is suggesting it to be a privileged port.
If this is the case, you could try to set it to another port by command line argument (see https://www.baeldung.com/spring-boot-change-port#command-line)
