expect:
1.can access the http://localhost:8000 successfully.
actual:
1.can’t access http://localhost:8000
investigation:
we expect that we can access the website after above steps, and we can use “docker ps -a” to make sure the the port 8000 is listening.type “docker ps -a” in PowerShell
show:

So, who can help to fix this problem to let me access the website which i want to run in Docker!
Or, who can point out which step I did is wrong!!
thanks in advanced!!!
