| ## Compute Engine Samples | ||
|
|
||
| These samples require two environment variables to be set: | ||
|
|
||
| - `GOOGLE_APPLICATION_CREDENTIALS` - Path to a service account file. You can | ||
| download one from your Google project's "permissions" page. | ||
| - `GCLOUD_PROJECT` - Id of your Google project. | ||
|
|
||
| ## Run the samples | ||
|
|
||
| Install dependencies: | ||
|
|
||
| npm install | ||
|
|
||
| ### sendgrid.js | ||
|
|
||
| Also required a `SENDGRID_API_KEY` environment variable to be set. | ||
|
|
||
| npm run sendgrid | ||
|
|
||
| ### vms.js | ||
|
|
||
| npm run vms | ||
|
|
||
| ### vms_api.js | ||
|
|
||
| npm run vms_api | ||
|
|
