To run jenkins inside docker
docker run --name jenkins-docker -p 8080:8080 -p 8081:8081 --volume jenkins-data:/var/jenkins_home jenkins/jenkins:jdk11
Make sure to expose port 8081 ${spring.server} to run the app on on the host (http://localhost:8081)
To run dockerised app on your local leverage the Dockerfile using
docker build -t myapp .
docker run --name my-app -p 4300:8081 myapp
If running app and database on a docker container, make sure to add the containers on a common network.
docker network create my-net
docker network connect my-net jenkins-docker
docker network connect my-net mysql-container \
This approach can be used to run server and database on the same AWS EC2 instance.
Get the IP address of containers using
docker network inspect my-net and use them wherever necessary, example : ${spring.datasource.url}
To connect Spring boot container to MySQL container, make sure to pass the correct url
spring.datasource.url=jdbc:mysql://mysql-container:3306/myDb
where mysql-container is the container name of MySQL server.
When installing docker on jenkins container, resolve permission issues using https://www.baeldung.com/ops/root-user-password-docker-container#:~:text=As%20an%20alternative%2C%20we%20can,PID%20of%20the%20running%20container.&text=This%20allows%20us%20to%20access,command%20to%20access%20any%20file.
