Get Started with the Choreo CLI

This guide walks you through the following sample use case:

  • Create a web application
  • Build the web application
  • Deploy the web application in the development environment
  • Promote the web application to the production environment

This guide utilized a simple to-do app built with Next.js and two basic environments: Development and Production.

Prerequisites

Follow the steps below to install the CLI:

  1. Install the Choreo CLI by running the command specific to your operating system:

    • For Linux and Mac OS 

      curl -o- https://cli.choreo.dev/install.sh | bash

    • For Windows (via PowerShell) 

      iwr https://cli.choreo.dev/install.ps1 -useb | iex

  2. Verify the installation by running the following command:

    choreo --version

Step 1: Login to Choreo

Run the following command to login to Choreo: 

choreo login

Follow the instructions on the console to open the link in the browser and login to Choreo.

Step 2: Create a project

A project in Choreo is a logical group of related components that typically represent a single cloud-native application. A project consists of one or more components.

Create a multi-repository project named ‘web-app-project’ by running the following command:

choreo create project web-app-project --type=multi-repository

Step 3: Create a Web Application component

In Choreo, a component within your project represents a singular unit of work in a cloud-native application. It can be a microservice, API, web application, or job/task. Each component is associated with a directory path in a Git repository containing the source code for the program.

Note

The Choreo CLI currently supports the following component types:

  • Service
  • Web Application
  • Webhook
  • Scheduled Task
  • Manual Task

  1. Fork the repository https://github.com/wso2/choreo-sample-todo-list-app. This contains a sample web application that you can use for this guide.

  2. To initiate the creation of a Web Application component within your project, use the following command: This triggers a wizard prompting you to provide details for your Git repository and other configurations for your component.

    choreo create component my-web-app --project=web-app-project --type=webApp

  3. Select the option Enter remote repository URL manually.

  4. Enter the following values for the prompts.

    Prompt value
    Configure source repository Enter remote repository URL manually
    Remote repository URL Your forked repository
    Branch main
    Directory .
    Build-pack nodejs
    Language Version 20.x.x
    Port 8080

    Note

    The prompts may vary based on the type of component and the chosen build pack.

Step 4: View component details

To view comprehensive information about the component, including basic details and service endpoint URLs once the services are deployed, you can use the following command:

choreo describe component "my-web-app" --project="web-app-project"

Step 5: Build the component

You must build the components before deploying them to a specific environment. Execute the following command to trigger the build:

choreo create build "my-web-app" --project="web-app-project"

Step 5.1: View build status

To check the status of a specific build, run the following command, replacing with the actual build ID obtained from the previous command:

Note

Typically, a build takes approximately 2 to 5 minutes to complete.

choreo describe build <build-id> --project="web-app-project" --component="my-web-app"

Step 5.2: View build logs

Once the build is complete, you can view the build logs for verification or debugging purposes. In the unlikely case, the build encounters any issues, the logs will help you troubleshoot.

choreo logs --type=build --project="web-app-project" --component="my-web-app" --deployment-track="main" --build-id=<build_id>

Step 6: Deploy to the Development environment

Once the build status indicates successful you can deploy the component in the Development environment by running the following command:

choreo create deployment "my-web-app" --env=Development --project="web-app-project" --build-id=<build-id>

Step 6.1: Verify the deployment in the Development environment

After deploying the component, you can retrieve the URL of the deployed web application and open the publicly available web page to verify its behavior. Use the following command to retrieve the URL:

choreo describe component "my-web-app" --project="web-app-project"

Step 6.2: View runtime logs

To observe runtime application logs of the web application in the Development environment, execute the following command:

choreo logs --type component-application --component my-web-app --project web-app-project --env Development --follow

Step 7: Deploy to the Production environment

Once you verify your application in the Development environment, you can proceed to deploy it to the Production environment with the following command:

  • Be sure to substitute with the id obtained after triggering the build.
choreo create deployment "my-web-app" --env=Production --project="web-app-project" --build-id=<build-id>

Step 7.1: Verify the deployment in the Production environment

To ensure a successful deployment to the Production environment, retrieve the URL of the deployed web application using the following command:

choreo describe component "my-web-app" --project="web-app-project"

Congratulations! You successfully deployed your web application in Choreo using the Choreo CLI.
