How to set environment variables in GitHub Actions

There are several ways to set environment variables in GitHub Actions. Here’s a comprehensive Q&A to address the provided headers:

1. How do I define environment variables in my GitHub Actions workflow?

You can define environment variables in your GitHub Actions workflow using the env keyword. The syntax is as follows:

<code class="yaml">env:
MY_VARIABLE_NAME: value</code>

For example, the following YAML defines an environment variable named MY_EXAMPLE_VARIABLE with a value of my-example-value:

<code class="yaml">env:
MY_EXAMPLE_VARIABLE: my-example-value</code>

2. What are the different ways to set environment variables when running GitHub Actions?

There are two main ways to set environment variables when running GitHub Actions:

• Using the env keyword: As described above, you can directly define environment variables in your GitHub Actions workflow file using the env keyword.
• Using the secrets keyword: GitHub Actions also allows you to define secrets, which are encrypted environment variables. Secrets can be set within your workflow file or in the GitHub Actions interface.

3. How can I use environment variables in my GitHub Action scripts?

Once you have defined environment variables, you can use them in your GitHub Action scripts. To reference an environment variable in a script, you can use the following syntax:

<code>${{ env.MY_VARIABLE_NAME }}</code>

For example, the following script references the MY_EXAMPLE_VARIABLE environment variable:

<code>echo ${{ env.MY_EXAMPLE_VARIABLE }}</code>

This script would print the value of my-example-value to the console.
