Welcome

So, you've decided to try Codefresh? Welcome on board!

Using this repository we'll help you get up to speed with basic functionality such as: compiling, testing and building Docker images.

This project uses JAVA to build an application which will eventually become a distributable Docker image.

Looking around

In the root of this repository you'll find a file named codefresh.yml, this is our build descriptor and it describes the different steps that comprise our process. Let's quickly review the contents of this file:

Compiling and testing

To compile and test our code we use Codefresh's Freestyle step.

The Freestyle step basically let's you say "Hey, Codefresh! Here's a Docker image. Create a new container and run these commands for me, will ya?"

    unit_test:
      title: Unit Tests
      image: maven:latest
      commands:
        - mvn -version

The image field states which image should be used when creating the container (Similar to Travis CI's language or circlecis machine`).

The commands field is how you specify all the commands that you'd like to execute

Building

To bake our application into a Docker image we use Codefresh's Build step.

The Build is a simplified abstraction over the Docker build command.

    build_image:
      title: Building Image
      type: build
      dockerfile: Dockerfile
      image_name: codefresh/java-spring-mvc-jdbc

Use the image_name field to declare the name of the resulting image (don't forget to change the image owner name from codefreshdemo to your own!).

Launching

This is where it gets real! Let's use Codefresh's Launch Composition step to run our composition within Codefresh!

Launching compositions within Codefresh means you have your very own staging area, at a click of a button!

    launch_composition:
      title: Launch Composition
      type: launch-composition
      composition: docker-compose.yml
      environment_name: 'java-spring-mvc-jdbc'
      entry_point: tomcat

Using the composition field, we direct Codefresh to the location if the docker-compose file in our repository.

Once the Launch Composition step has completed successfully, you'll be able to review and share your running composition in the Environments page.

Now that we've gotten a grip on the flow, let's get cracking!
