Create Application

In KubeRocketCI, all software components, such as applications, libraries, Terraform infrastructures, and automated tests, are referred to as codebases. KubeRocketCI provides flexible methods for scaffolding these components.

This guide will walk you through the process of creating a Go application using the Gin framework. The Marketplace will be used to streamline the application creation process.

Application Onboarding​

To create the first application, complete the instructions below:

  1. In the KubeRocketCI, navigate to Marketplace.

  2. In the Marketplace section, select Web Applications with Gin Framework:

    Marketplace applications

  3. In the appeared window, define the following values and click Apply:

    • Component name: my-go-gin-app
    • Description: My first application
    • Git server: github
    • Repository name: <github_account_name>/my-go-gin-app
    • Codebase versioning type: edp
    • Start version from: 0.1.0
    • Suffix: SNAPSHOT

    Application blank

  4. As soon as the codebase is created, navigate to it via the notification at the bottom left corner or click the Components section:

Build Application​

Having created the Go application, proceed to build it by performing the following actions:

  1. In the create project page add new project to analyze it.

    note

    Project name in the Sonar cloud must be the same as codebase name.

    Add new project

    Set the Previous version option and click Create project.

    Add new project

  2. On the project menu, navigate to Branches menu, select master branch and rename it to main.

    Change default branch

  3. On the account settings copy the value of the SonarCloud organization name.

    Organizations page

  4. In the component details page, expand the application and click the GIT button:

    Marketplace notification

  5. In the opened Source Code. In the main branch in GitHub, open the sonar-project.properties file and include the sonar.language=go, and sonar.organization parameters where sonar.organization is equal to the value copied in the previous step, resulting in the following configuration:

    sonar.projectKey=my-go-gin-app
    sonar.projectName=my-go-gin-app
    sonar.go.coverage.reportPaths=coverage.out
    sonar.test.inclusions=**/*_test.go
    sonar.exclusions=**/cmd/**,**/deploy/**,**/deploy-templates/**,**/*.groovy,**/config/**
    sonar.language=go
    sonar.organization=<organization-key>
  6. Commit the changes.

  7. In the component details page, click the Trigger build pipeline run button:

    Triggering pipeline run

    note

    After first project scan, sonar creates Quality Gate for this project, and scan will be failed, rerun pipeline to analyze project with new Quality Gates.

  8. To check the status of the build pipeline, click on its name:

    Pipelinerun logs

  9. Once the build fails, click the failed stage name to open the Tekton pipeline run:

    Failure details

  10. In KubeRocketCI, initiate the build pipeline again and wait for its completion.

    Successful pipelinerun

Build pipelines in KubeRocketCI are specifically designed to generate an executable image of an application. Once the build process is complete, the resulting image can be deployed and run in a target environment.

Now that you have successfully built an application, the next step is to create an environment for deployment. In order to deploy the application, you will need to install and integrate Argo CD. To learn how to install and integrate Argo CD, please refer to the Integrate Argo CD page.
