How to hand over credentials with quarkus as main application without application.properties

Question

I have a quarkus application which is a main app. Here is an simplified example:

@QuarkusMain
public class MyXYZTool { 

    public static void main(String... args) {
        Quarkus.run(MyXYZTool.class, args);
    }

    public static class CacheApp implements QuarkusApplication {
        @Inject
        AgroalDataSource dataSource;

        @Override
        public int run(String... args) throws Exception {
          

            readCommandLineParameter(args);
            //and so on...
          
            return 0;
        }
    }

};

I have also an application.properties which contains the credentials to access to an Azure cloud blobstorage.

Secrets.BlobStorages.xyz.ConnectionString=abcaccesstoken

I start my app from command line like this:

//start from command line
java -jar  ./target/xyz-runner.jar  

My app works also so far. But I want to hand over the credentials to access an Azure cloud blob storage over the command line. It should not be hardcoded in the application.properties. This has security reasons.

I ask me how I can hand over Secrets.BlobStorages.xyz.ConnectionString over the command line and activate this. Can somebody help me?

I have found an answer to my question by this webside from Quarkus: https://quarkus.io/guides/config#overriding-properties-at-runtime I tried it out and it works.
