Guidance on setting tags during Automated Deployment to Docker hub step:

The related image would be deployed to Docker hub automatically as soon as commit message include string "#sign-off". Below 2 kinds of tags would be set.

1. Set tag as the value of version folder name. For example:

Update files which under ..\my-image\0.1, 
it would push my-image:0.1 to Docker hub.

2. Set tag as "latest".

• There is 1 file names latest.txt exist under image folder.
• The value of above file is as same as the related image version. For example:

Update files which under ..\my-image\0.1, 
..\my-image\latest.txt is exist and the content is "0.1", 
it would also push my-image:latest to Docker hub.

Deploying Samples

You can deploy these samples directly through the Azure Portal

1. Go to Azure portal
2. Search for Web app for Containers
3. Enter web app name , susbcription , resource group
4. Select configure container and enter the docker hub image name with the tag name. you can find all the docker hub images here
5. Review the readme.md for the imae you are using to make sure any additional configuration such as app settings need to be updated. Make the necessary changes
6. Now browse the application

Note: The first request can take longer to complete since the docker image needs to be pulled and run on the container for the first request. This can occur when you scale up your application or the instance gets recycled.
