Instance

Use Docker image nginx:latest to start a container in background mode and name the container Mynginx:

Docker Run--name mynginx-d nginx:latest

Use mirror nginx:latest to start a container in background mode and map the container's 80 port to the host random port:

Docker Run-p-D nginx:latest

Using mirrored nginx:latest, start a container in background mode, map the container's 80 port to the host's 80 port, and the host's directory/data map to the/data of the container:

Docker run-p 80:80-v/data:/data-d nginx:latest

Bind the container's 8080 port and map it to port 80 on the local host 127.0.0.1:

Docker run-p 127.0.0.1:80:8080/tcp Ubuntu bash

Use mirror nginx:latest to start a container in interactive mode and execute the/bin/bash command inside the container:

Docker run-it Nginx:latest/bin/bash
