Today I decided to start creating a small repository with all useful custom policies I created by myself or I found during huge researches. This article is more a wiki than a blog post and will be always updated if new things come up.

The great thing here is that you can just copy paste the Azure policy snippets and reuse it.

• Adding a creation tag on Resources and Resource Groups

Adding a creation tag on Resources and Resource Groups

• This policy is used to add automatically the Creation Date to Azure Resources and Resource Groups during the Creation or Deployment.
• Tag Name = DateCreated
• Tag Value = current UTC timestamp in the following format: 2021-02-15T13:43:28.8652865Z
  –> If somebody knows how to trim or format this please let me know 🙂
