It just reads a number from Redis, and gets a query result from Postgres. mynodeapp is a very simple node.js (express) app. The folder /DockerizingWebAppTutorial contains all we need. You need to run the following commands as root. One is apt, the other is yum.Ĭurrently, Docker's official installation on Debian 8 does not work. For example, the package management tools on Debian and CentOS are different. I choose Debian instead of 64-bit CentOS because I don't want to spend any time on the differences. Actually the host's OS can be different to the container's OS. The main reason I choose Debian is its distribution size is small and Docker recommends it in Best Practices(it's ridiculous that almost all examples at use ubuntu).
If your Linux is 32-bit, you have to re-install the 64-bit version. Install Docker on the hostĭocker runs on a 64-bit Linux OS only.
We can easily create/delete/change/re-create containers. With Docker, we can put each service in a container. It's not easy to change the settings or the content a lot, because they are in the same environment. The traditional way of building a (low-traffic) website is we install the web app, cache, database, Nginx directly on a server. The key feature I like most is it provides resource isolation. Why Dockerĭocker is a virtualization technology. We use Redis as a cache store, Postgres as the database, and Nginx as the reverse proxy server. In this tutorial, the web app is a node.js(express) app.
This tutorial introduces how to deploy a web app, Redis, Postgres and Nginx with Docker on the same server. It features thread-safety, client-side sharding, pipelining, and an obsession for performance. Redis-rb () -A Ruby client library that tries to match Redis' API one-to-one, while still providing an idiomatic interface. Redis () -Redis is an open source (BSD licensed), in-memory data structure store, used as database, cache and message broker. If it replies “PONG”, then it’s good to go!

Database management application for OS X designed to help work with Redis data structure servers in a clean and user-friendly environment.
Running the above simple script will provide this figures in my Mac OS X system, running over the loopback interface, where pipelining will provide the smallest improvement as the RTT is already pretty low: without pipelining 1.185238 seconds with pipelining 0.250783 seconds. By using Homebrew, you greatly reduce the cost of setting up and configuring Redis on Mac OSX.
