error when connecting local mysql to gitlab ci/cdpipeline - mysql

Question

I have a spring-boot application with mysql database connection and junit test classes. That's working fine in local machine. But when I pushed the code to Gitlab to build a CI/CD pipeline, the build stage is failing due to mysql connection issue.
application.yml
spring:

I tried so many ways to connect my local mysql to gitlab. But I couldn't make it work. Can someone help me to figure out the issue?

Answer 1

It seems the issue lies in the fact with how you try to access your DB in gitlab.
When you add the mysql service
services:
- docker:dind
- mysql:8
The database is accesible with hostname mysql not localhost.
As it is described in Gitlab docs:
https://docs.gitlab.com/ee/ci/services/#how-services-are-linked-to-the-job
This means you need to edit the application.yml
From
url: jdbc:mysql://localhost:3306/usermanagementdb?createDatabaseIfNotExist=true
To
url: jdbc:mysql://mysql:3306/usermanagementdb?createDatabaseIfNotExist=true
