But can't open the web app on browser: 4.147.67.11 xxtest-demoproject.australiaeast.azurecontainer.io

Answer 1

Your application listens on port 8000, but your ACI listens on ports 80 and 443.

You can listen on several ports with ACI but can't redirect to a single port. If you want to forward 80 and 443 to 8000, you'll need to use App Gateway, for example.

Please try with:

az container create -g xxtestrg --name test-ci --image xxtestcr.azurecr.io/demoproject:v1.0 --ports 8000 --cpu 1 --memory 1.5 --dns-name-label xxtest-demoproject

then try http://<ip/url>:8000
