| # This introduces a necessary delay. Because the preview evironment | |
| # URL is announced to the pull request as soon as all the steps | |
| # finish, what sometimes happens is that a viewer of the PR clicks | |
| # that link too fast and are confronted with a broken page. | |
| # It's because there's a delay between the `azure/arm-deploy` | |
| # and when the server is actually started and can receive and | |
| # process requests. | |
| # By introducing a slight "delay" here we avoid announcing a | |
| # preview environment URL that isn't actually working just yet. | |
| # Note the use of `--fail`. It which means that if it actually | |
| # did connect but the error code was >=400, the command will fail. | |
| # The `--fail --retry N` combination means that a 4xx response | |
| # code will exit immediately but a 5xx will exhaust the retries. | |
