Gitlab ci cd pull code from repository before building asp net core

Introduction

ASP.NET is a popular programming language used for building web applications. It provides a framework for dynamic websites, web services, and web applications. In this article, we will explore how to pull code from a GitLab repository before building an ASP.NET Core application using GitLab CI/CD.

Setting up GitLab CI/CD

GitLab CI/CD is a powerful continuous integration and continuous deployment tool that allows you to automate the build, test, and deployment processes of your applications. To get started, you need to set up a GitLab CI/CD pipeline for your ASP.NET Core project.

First, a .gitlab-ci.yml file in the root directory of your project. This file defines the stages and jobs for your CI/CD pipeline. Here's an example of a basic .gitlab-ci.yml file:


stages:
  - build

build:
  stage: build
  script:
    -  restore
    - dotnet build

In this example, we have a single stage “build” and a single job within that stage. The job runs two commands: dotnet restore and dotnet build. commands restore the project dependencies and build the ASP.NET Core application, respectively.

Pulling Code from GitLab Repository

Now that we have set up the basic CI/CD pipeline, let's add a step to pull the code from the GitLab repository before building the application. We can use the GitLab CI/CD to authenticate and clone the repository.

Here's an updated version of the .gitlab-ci.yml file that includes the code pulling step:


stages:
  - build

build:
  stage: build
  script:
    - git clone $CI_REPOSITORY_URL
    - cd my-project
    - dotnet restore
    - dotnet build

In this example, we have three new commands to the script. The first command, git clone $CI_REPOSITORY_URL, clones the GitLab repository using the $CI_REPOSITORY_URL variable. The second command, cd my-project, the directory to the cloned repository. Finally, we run the dotnet restore and dotnet build commands to build the ASP.NET Core application.

Conclusion

In this article, we have explored how to pull code from a GitLab repository before building an ASP.NET Core application using GitLab CI/CD. By adding a few simple commands to the CI/CD pipeline, we can automate the of pulling the latest code and building the application. This helps ensure that our application is always up to date and ready for deployment.

Remember to customize the pipeline according to your specific requirements and project structure. Happy coding!
