How to run a Spring Boot App in a Docker Container in Cloud Foundry

This is the repo for a Spring Boot app in Docker Original Repo

The Spring boot app is deployed in Cloud Foundry as a Docker Container

5-Steps

1. Clone the Repo --

     git clone https://github.com/rjain-pivotal/spring-boot-docker-cf.git

2. Build it and Run it locally -- If using Maven

     mvn package && java -jar target/gs-spring-boot-docker-0.1.0.jar

   If using Gradle

     ./gradlew build && java -jar build/libs/gs-spring-boot-docker-0.1.0.jar
   

3. Containerize it --

   Set up the environment:

    export DOCKER_TLS_VERIFY="1"
    export DOCKER_HOST="tcp://192.168.99.101:2376"
    export DOCKER_CERT_PATH="/Users/mary/.docker/machine/machines/default"
    export DOCKER_MACHINE_NAME="default"
    # Run this command to configure your shell:
    # eval "$(docker-machine env default)"
   

   If using Maven

      $ mvn package docker:build
      # Push the Image to Docker 
      $ docker push <docker-user>/gs-spring-boot-docker

   If using Gradle

      $ ./gradlew build buildDocker

4. Check and Run --

      $docker images
      # Get the Docker Machine VM IP if running on a MAC 
      $docker-machine env default (Get the Machine IP)
      $docker run -p 8080:8080 -t rjain15/gs-spring-boot-docker
      $curl http://192.168.99.100:8080  (Use the Machine IP)

5. Run it in Cloud Foundry --

      $cf push -o <docker-user>/gs-spring-boot-docker -c "java -Djava.security.egd=file:/dev/./urandom -jar /app.jar"
