Full Description

Use this tutorial to familiarize yourself with codefresh.yml file and Codefresh functionality.

This tutorial is based on Let’s Chat app.

Let’s Chat is self-hosted chat app for small teams or big

This tutorial will walk you through the process of adding the following :

  • Build step - that will build Docker image for your Let’s Chat app

  • Push to registry step - that will push your image to Docker Hub

  • Unit Test step - A freestyle step that runs the unit test of the demo chat after the build

  • Composition step - This step will create and launch a composition.

So, the first thing you need to do is :

Fork our repo

Enter the following link and fork Let’s Chat app!:

Add a service

Now enter Codefresh and add your Let’s Chat app as a Codefresh service.

Click on Add Repository

Now add your forked demochat repo. You can search for it by typing "demochat" to search. You can also Add by URL here.

Also, choose the branch for your first build (in this case master)

When you finish press Next.

Select how you would like to setup your repository. In this case, our repo has a Dockerfile, so we'll select the middle option.

By default, Codefresh searches for your Dockerfile at the root level of your repository, by the name "Dockerfile". The demo-chat example includes a Dockerfile in the root level.

Review your Dockerfile, and click Create to add your repository.

Clicking on Build button will trigger a regular build.

Great, you are running your build for the first time!

Push your image to Docker registry

Click on Repositories, and then click on the Pipelines gear.

Scroll down to Workflow, and you will see a Push to Docker button. If you have set up your credentials, click Save at the bottom of the screen. Otherwise- click on the integration page link.

Write your User/Password info, and click Save to connect.

Unit test your image

Let's head over to Piplines again.

Scroll down to Workflow under Build and Unit Test

We'll type in echo $(date) in the Unit Test Script area. This will print the date, and we'll be able to see our test in action.

Let's click Save, and Build to see it in action.

Great- the date has been printed!

Now let's add a full composition that also contains mongo db.

Add composition

Our Let's Chat app needs mongo in order to work, so let's add it!

You can read more about compositions in our docs, but we will also walk through the process here :

Click the Composition view icon in the left pane, and click the Add Composition.

Choose a name for your composition

We are going to build our comp from scrath, so click Empty Composition

Now we will click Add Service and add demochat, the port (50000), and mongo.
Everything looks good here- so let's go ahead and launch by clicking the rocket ship...

Once it has completed, a link to our app will be displayed. Let's click it to see if it worked.

Success! We have successfully launched a composition.
