Spring Boot Application on Docker

spring-boot-docker

Getting Started with Docker using Spring Boot

Maven Build the code :

mvn install

Run the Spring Boot application :

java -jar target/spring-boot-docker-0.1.0.jar

Verification :

http://localhost:8080

Docker

1. Docker Build

docker build --compress --force-rm -t {Docker_Hub_Username}/{Docker_Hub_RepoName}:{Tag} .

Example : docker build -t vinodjayachandran/spring-boot-docker:1.0 .

2. On successful execution of above command, it will create a docker image in your local which you can verify with the below command. It will list the set of images on your machine.

docker images

3. Run Docker image locally on a container with a name for the container.

Example : docker run -p 8080:8080 -t vinodjayachandran/spring-boot-docker:1.0 --name=MyTestContainer

4. Verify if the container is up. Your image will be listed with status as up along with container id. Without the option --all it will list only running containers

Example

$ docker container ls --all

5. Stop/Start the container with container id retrieved from Step 4. After stopping the container you verify again with commands from Step 4

Example

docker stop {CONTAINER ID}

docker start {CONTAINER ID}

6. Rename container

docker rename {EXISTING CONTAINER NAME OR ID} NEW_NAME

7. Delete container

docker rm {EXISTING CONTAINER NAME OR ID}

8. Remove one or more images

9. Push the docker image to docker hub/registry

   Login to Docker Hub/Registry

       $ docker login --username={userName} --password={pwd}
   

   Providing password directly on CLI isn't recommended. From a security perspective, we can have the password stored in a file and provided at run time through stdin

   Push the image to docker hub

10. Configure automated builds from GitHub and BitBucket
