# NOTE! This is specifically and only for github/docs-internal. | |
# **What it does**: Build and deploy an Azure preview environment for this PR in github/docs-internal | |
# **Why we have it**: It's our preview environment deploy mechanism, to docs-internal repo | |
# **Who does it impact**: Writ-access contributors. | |

# The advantage of 'pull_request' over 'pull_request_target' is that we | |
# can make changes to this file and test them in a pull request, instead | |
# of relying on landing it in 'main' first. | |
# From a security point of view, its arguably safer this way because | |
# unlike 'pull_request_target', these only have secrets if the pull | |
# request creator has permission to access secrets. | |

# 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. | |
