This article is from the "Knowledge Forest" In the previous explanation "09-docker run Wordpress+mysql Fast build Web site (Docker series)" described the use of --link way to let Wordpress and MySQL container, which is about to become obsolete and needs to be replaced by a Docker network method. The following is the wa

What is the link mechanism of Docker If you want to communicate between multiple Docker containers on the same host, you can communicate by using the IP address of the container, or you can communicate through the host IP plus the port number exposed by the container, which will cause the IP address to be hard coded, inconvenient to migrate, and the IP address w

Docker Learning Summary of cross-host link　　Docker is a powerful feature, but it's not easy to manage Docker. The following describes a user case that you will encounter in your daily work. For example, there are now two hosts, labeled Hosta and HostB, respectively. Hosta is used to run Oracle services, and HOSTB is us

When using Docker, we often encounter the application that I need two or more containers, some of which need to use the services provided by other containers. For example, we need a container to provide MySQL database services, while the other two containers are connected as clients to use the MySQL database service. Let's take a look at how Docker through link t

In general, we will install Nginx, PHP are installed in the same container, in order to expand convenience, we hope that nginx container and PHP container separate. Then you can use the Docker link command to do this.Required Image: Nginx 1.12.2 PHP (including php-fpm7.1) 7.1 Here the Nginx image selection daocloud.io/library/nginx:1.12.2-alpine , PHP image compiled by itself (the selectio

Container and container communicate with each other. The official name is linking containers together! The most common is to run a web iner and a DB container to link the Web container to the DB container; A network channel (BRIDGE) is established between two containers through link, and DB iner only needs to know the alias and open port number of the previous container; Example: Start a DB container firs
