New option to try out Web App for Containers
Web App for Containers is a fully managed platform to deploy, run, and scale your apps hosted in containers. There's now an option to try it out, with no credit card required.
Sign in to the Try Azure App Service page and select Web App for Containers. You can use one of the built-in containers or enter your own image name to work with. You're asked for a Microsoft sign-in, which will grant Azure portal access for 30 minutes to try out the feature.
