Passing Env Variables from GitHub Actions to JSON Configuration Files

In modern software development, particularly when using Continuous Integration/Continuous Deployment (CI/CD) practices, managing configuration files dynamically is essential. One common task developers face is passing environment variables from platforms like GitHub Actions to configuration files such as JSON. This guide will guide you through the process of how to inject environment variables into a JSON file using GitHub Actions.

The Problem

This task can be tricky if you don’t know the right steps to take. Fear not! Below are the strategies to dynamically inject that environment variable into your JSON configuration file right from your GitHub Actions workflow.

The Solution

Step 1: Set Up Your JSON File

Step 2: Create Your GitHub Actions Workflow

In your GitHub Actions workflow YAML file (usually found in .github/workflows/), you will need to add a step to replace the placeholder in the JSON file. Here’s how you can do it:

The Code Snippet

Add the following code snippet in your workflow file:

Explanation of the Code

- name: "inject server ip": This line provides a name for the step in your GitHub Actions workflow.

env:: This section specifies the environment variables that you want to make available to the run command. Here, server_ip will be assigned the value of your secret Node_Server_Url.

run:: Under this section, the actual command is executed. The sed command is a stream editor used to perform basic text transformations. The -i option indicates that the file should be edited in place:

Step 3: Commit Your Changes

Conclusion

By following the above steps, you can efficiently pass environment variables from GitHub Actions to your JSON configuration files. This approach makes your development and deployment processes more dynamic and flexible, allowing you to easily incorporate different configurations based on your environment settings.

Now that you have your configuration files set up, your CI/CD pipeline is one step closer to being fully automated and adaptable to different environments. Happy coding!
