Docker build-t Whh/nginx-file:v1.

Docker run-d-it-p 93:80--name nginx

Now look at the use of Dockerfile

Mirroring can be established by using the Docker build command.

Text file Dockerfile is usually required, as in the following example:

From Hub.c.163.com/library/nginx----based mirroring

Run echo "Hello World" >/etc/nginx/index.xml----append to the end of index.html

Expose---exposed 80 ports

Cmd ' nginx '----start Nginx service

After saving, run Docker build-t mynginx:1.0.

Then run Docker images and look at the mirrors that were built.

Via Docker run-d-P 8082:80--name nginx_web mynginx:1.0

Finally, access to Nginx's index.html content via http://ip:8081
