Document healthcheck URL requirement for custom containers
With Web App for Containers, it seems Azure uses a special URL "/robots933456.txt" to check when the container has started, and expects a valid HTTP response (404 is fine). This requirement for custom containers should be mentioned in the documentation! (and preferably, it should be configurable)
Yes it should have been mention din the documents. I was really wondering how come my web app created using azure webapp keeps showing 404 error code.

+3 I've just wasted a couple of hours just because my server was ignoring such URL (no response). Giving 404 to /robots933456.txt resource fixed the issue

+1 for this feature. It fills up my docker log with 404 from this /robots933456.txt requisition.
