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 Python and Django 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:

Testing

To 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?"

test_the_code:
    image: python:slim
    commands:
        - python -m unittest composeexample.utils

The image field states which image should be used when creating the container (Similar to Travis CI’s language or circleci`s 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_the_image:
    type: build
    image_name: codefreshdemo/djanga

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_the_composition:
    type: launch-composition
    composition: docker-compose.yml

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!
