The whole structure is very simple, it is a Web container and a database container, is a simple application. Now it is popular to support high concurrency, clustering, or at least a number of Web servers, so often use load

Docker Introduction Docker is an open source application container engine that allows developers to package their apps and dependencies into a portable container, and then publish it to any popular Linux machine or virtualization. Containers are completely using the sandbox mechanism, and there will be no interface between each other. Profile Docker to give a

This article describes the configuration of simple load balancing on Docker, the host for Ubuntu 14.04.2 LTS, two CentOS containers, the host installation Nginx, two containers installed TOMCAT7. The structure is as follows:The idea of this scenario is to map the port of the host and the port of the Docker container (t

the content of the specified container ip,-v refers to the local configuration of the Config.ini file, and then map it into the NDB_MGMD container Config.ini configuration content is as follows [NDBD DEFAULT]noofreplicas=2datamemory=80mindexmemory=18mDatadir=/usr/local/mysql/data [NDB_MGMD DEFAULT]Datadir=/var/lib/mysql-cluster [NDB_MGMD]Nodeid=1hostname=192.166.0.2 [NDBD]nodeid=10hostname=192.166.0.10 [NDBD]nodeid=11hostname=192.166.0.11 [MYSQLD]nodeid=100hostname=192.166.0.100 [MYSQLD]Nodeid=

Q:swarm What is the ultimate goal, just to manage the container, have you ever considered increasing the resource utilization, and will the resource elasticity be scaled up, eventually lifting all the machine load and preve
