| # **What it does**: Build and deploy an Azure preview environment for this PR | |
| # **Why we have it**: It's our preview environment deploy mechanism, to docs-internal and docs public repo | |
| # **Who does it impact**: All contributors. | |
| # !!! | |
| # ! This worflow has access to secrets, runs in the public repository, and clones untrusted user code. | |

| # 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. | |

| # code will exit immediately but a 5xx will exhaust the retries. | |
