试图到达我的容器我得到“这个网站无法到达”

I've tried to run this command

• docker run -t -i -d --name demo -p 8080:80 ubuntu-apache2-img

Then I've looked for all my containers

• docker ps -a
• 8fffa1a8da7b ubuntu-apache2-img "/bin/bash" 59 minutes ago Up 3 minutes 0.0.0.0:8080->80/tcp demo

Ho cercato l'IP del mio container

• docker inspect 8fffa1a8da7b | grep '"IPAddr' | awk '{print $2}'
• "172.17.0.45",

And If I try to open http://172.17.0.45:8080 from my host, i get "This site can’t be reached"

Why?

Are you using docker host ? If so, you might want to change the IP address (container IP) with your docker host IP address.
