           How do I use `latest` or a static tag for my container image?
         answer: |
-          Avoid using static tags like `latest` for container images. Using static tags can lead to caching problems and can make your app difficult to troubleshoot. Instead, use unique tags for each deployment, such as a Git hash or date and time to ensure that updates are properly tracked and deployed.

 - The Application Insights endpoint doesn't accept metrics.
 - Configuration settings live at the environment level. You can send different data types to different destinations, but you can't split up your data by app. For example, in the same app you can send metrics to Datadog, and traces to App Insights.
