在AWS Elastic Beanstalk上部署Spring

Question

I am trying to deploy my Spring Application in Java to AWS Elastic Bean stalk. But I have a few problems caused by not understand AWS enough and tutorials which are to old (Interface changed etc.)

Few questions:

I created a Application and it is configured as Tomcat 8 with Java 8 running.

so far so good. When I click on the Configuration menu entry, I wanted to enable a mysql instance / db, but I am not able to modify it (select an instance class etc.) or get access to the database with eg SequelPro.

In "Software" where I can set the environment variables I tried to get a connection to the database, if it worked I don't know because I can not find the log for the spring application deployed and cannot access the database from outside. Connection String looks like this. ("someurl" is the real url ^^):

jdbc:mysql://someurl.com/ebdb

Btw. when I click on the URL of the environment I get an 404.

I hope someone can help me deploying.

Beanstalk is container-based service, you can't run MySQL on same instance, you should start corresponding one from RDS or use a separate EC2 instance. Beanstalk instances should be stateless as any moment new instance can be added or removed.

I can not find the log for the spring application deployed

You can access logs and access the instance via EB CLI https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/eb3-ssh.html Tou should be able to test DB connectivity same way
