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?
org.springframework.context.ApplicationContextException: Failed to start bean 'zeebeClientLifecycle'; nested exception is io.camunda.zeebe.client.api.command.ClientStatusException

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)

Error when running application - "|WARN|Fail to retrieve token com.amazonaws.SdkClientException: Failed to connect to service endpoint:"

I have been getting these errors for the past few days when I try run my app locally. I'm completely out of ideas of how to fix this. Any idea what could be the problem? Below is the trace. The app is using aws-sdk 11 and running on java 11.

The problem is the SDK now logs a warning when it can't retrieve the AWS instance metadata. It may help to specify which AWS region you want using an environment variable (I haven't seen this work, but others have):
export AWS_REGION=us-east-1
Alternately, the Spring Cloud team recommends suppressing the warning:
https://github.com/spring-cloud/spring-cloud-aws/issues/556
https://github.com/juho9000/spring-cloud-aws/commit/24edbdc57086f1043d3a49f6c8841cc1751ee747
On application startup, for its internal purposes Spring Cloud AWS performs a check if application runs in AWS cloud environment
by using EC2MetadataUtils class provided by AWS SDK. Starting from version 1.11.678, AWS SDK logs a warning message with exception when this check is made outside of AWS environment.
This warning message can be hidden by setting ERROR logging level on com.amazonaws.util.EC2MetadataUtils class.
logging.level.com.amazonaws.util.EC2MetadataUtils=error

How should I consume rest web service with ssl

I am supposed to write client which must fetch data from web service. I am follow this guide: https://spring.io/guides/gs/consuming-rest/ The website has https.
My code:
#SpringBootApplication
public class TransportApplication {
private static final Logger log = LoggerFactory.getLogger(TransportApplication.class);
public static void main(String[] args) {
SpringApplication.run(TransportApplication.class, args);
}
#Bean
public RestTemplate restTemplate(RestTemplateBuilder builder) {
return builder.build();
}
#Bean
public CommandLineRunner run(RestTemplate restTemplate) throws Exception {
return args -> {
ResponseEntity<String> response = restTemplate.getForEntity("https://XXXXXX", String.class);
log.info(response.toString());
};
}
}
When I run my program I get this exception:
Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

It seems like I need to enable ssl. Okay, I have follow few guides and they don't really help me. One of them: https://snmaddula.bitbucket.io/enable-https-in-spring-boot-app/
I also tried to disable ssl(I did it in postman) it seems like some of solutions are outdated or I don't get how to use them. Such an example is the best answer from this post: Disabling SSL Certificate Validation in Spring RestTemplate
Please help me, I think my task must be very easy but this I have already spent a few hours trying to make this program work.

You need to add the certificate of the rest web service to the truststore file of the used JVM located at %JAVA_HOME%\lib\security\cacerts.
For getting the certificate open the url you are calling in a chrome and download it.
You can download the certificate by clicking on site information icon then details than copy to file as below:
Afterwards open git bash by running it as administrator and run this command:
keytool -import -alias alias_of_your_choice -keystore '%JAVA_HOME%\lib\security\cacerts' -file filepath
After adding it to the keystore you might want to restart the pc.

I think your rest api providers ssl certificate is not valid one
If you are developing that service too, use lets encrypt to generate valid certificates
