# GCP Environment Variables

Adding a GCP project to your track also sets a list of [environment variables](https://en.wikipedia.org/wiki/Environment_variable) that you can use in commands and scripts:

<table data-header-hidden><thead><tr><th width="542">Environment variable</th><th>Description</th></tr></thead><tbody><tr><td>Environment variable</td><td>Description</td></tr><tr><td><code>INSTRUQT_GCP_PROJECTS</code></td><td>A comma-separated list of project names that can be used to fill ${NAME} in the variables below</td></tr><tr><td><code>INSTRUQT_GCP_PROJECT_${NAME}_PROJECT_NAME</code></td><td>This injects the project display name</td></tr><tr><td><code>INSTRUQT_GCP_PROJECT_${NAME}_PROJECT_ID</code></td><td>This injects the project ID</td></tr><tr><td><code>INSTRUQT_GCP_PROJECT_${NAME}_USER_EMAIL</code></td><td>This injects the email address of the end user that has access to the project</td></tr><tr><td><code>INSTRUQT_GCP_PROJECT_${NAME}_USER_PASSWORD</code></td><td>This injects the password of the end user</td></tr><tr><td><code>INSTRUQT_GCP_PROJECT_${NAME}_SERVICE_ACCOUNT_EMAIL</code></td><td>This injects the email address of the end user services account for this project</td></tr><tr><td><code>INSTRUQT_GCP_PROJECT_${NAME}_SERVICE_ACCOUNT_KEY</code></td><td>This injects the Base64 encoded key for the end user services account</td></tr><tr><td><code>INSTRUQT_GCP_PROJECT_${NAME}_ADMIN_USER_EMAIL</code></td><td>This injects the email address of the admin user (Admin credentials are only injected into lifecycle scripts)</td></tr><tr><td><code>INSTRUQT_GCP_PROJECT_${NAME}_ADMIN_USER_PASSWORD</code></td><td>This injects the password of the admin user (Admin credentials are only injected into lifecycle scripts)</td></tr><tr><td><code>INSTRUQT_GCP_PROJECT_${NAME}_ADMIN_SERVICE_ACCOUNT_EMAIL</code></td><td>This injects the email address of the admin services account (Admin credentials are only injected into lifecycle scripts)</td></tr><tr><td><code>INSTRUQT_GCP_PROJECT_${NAME}_ADMIN_SERVICE_ACCOUNT_KEY</code></td><td>This injects the Base64 encoded key for the admin services account (Admin credentials are only injected into lifecycle scripts)</td></tr></tbody></table>

### Example

This example shows the id of the GCP project from a terminal by using two environment variables. The value of the `INSTRUQT_GCP_PROJECTS` environment variable is inserted in the `INSTRUQT_GCP_PROJECT_${NAME}_PROJECT_ID` environment variable.

To follow along:

1. Start your GCP project track and start the first challenge.
2. Move over to the `Cloud CLI` terminal and enter the following command:

   ```xml
   eval echo "\${INSTRUQT_GCP_PROJECT_${INSTRUQT_GCP_PROJECTS}_PROJECT_ID}"
   ```

   ↳ The terminal shows the id of your GCP project.
