basic dockerfile

This article is mainly about how to use Dockerfile to build the image of the LNMP environment, provided that you have installed Docker one, new Dockerfile file .

As we all know, if the outside to communicate with the Docker container, in addition to the link must be a port mapping, the following first describes the use of the Dockerfile expose, and then do a multi-port random mapping example bar. The format is:EXPOSE PORT Here's my dockerfile. # Tomcat # Version 0.0.1 # get_image from 192.168.0.216:5000/centos # maintainer_info Maintainer Hongxue hongxue@showjo

Objective When you use the Docker build to make your own image, you use the Run command to perform some operations to install some of the necessary software. And some software installation process will require users to enter yes/no or y/n to determine something before entering the next installation. This can be solved in dockerfile. if it's an occasion to install with Yum, RUN Yum install-y xxx The-y parameter can skip the software query, which i

Basic concepts: Container Container. Each container can be viewed as a standalone host. The creation of container usually has an image as its template. Analogy to a virtual machine can be understood as image is the mirror of the virtual machine, and container is a running virtual machine. A virtual machine image can create multiple running virtual hosts and be independent of each other. Note: Once created, container will persist if not r
