To extend Docker and Fig to production, you can use tools such as Flocker. Note, I said development and test, not production. Using Docker and Fig, a Developer can pull down ready-made base containers from Docker Hub, configure the containers as part of a multi-tier application environment, deploy our MEAN application components to the containers, and start the applications, all with a short list of commands. The tool, Fig, provides quick, automated creation of multiple, linked Docker containers. An additional tool that the MEAN.JS project has implemented, to automate the creation of multiple Docker containers, is Fig. The MEAN.JS project has been very progressive in implementing Docker, to offer a more realistic environment for development and testing. We can easily add more containers, for more functionality, such as load-balancing and reverse-proxies ( nginx), and caching ( Redis and Memcached). Likewise, we can isolate the Node.js web server, along with the rest of the components (Mongoose, Express, Passport) on the application and presentation tiers, into a Docker container. Just as we would always run a separate database server or servers for MongoDB, we can isolate MongoDB into a Docker container. Using Docker, we can ‘Dockerize’ or containerize each tier of a MEAN application, mirroring the physical architecture we would deploy a MEAN application to, in a Production environment. Lastly, the presentation tier (front end) has client-side tools, such as AngularJS and Twitter Bootstrap. The application tier can also contain other components, such as Mongoose, a Node.js Object Document Mapper (ODM) for MongoDB, and Passport, an authentication middleware for Node.js. ![]() The application tier (logic tier) contains Node.js and Express. The MEAN application’s data tier contains the MongoDB noSQL database. Being a full-stack JavaScript solution, MEAN applications are based on a multi-tier architecture. ‘Dockerized’ apps are completely portable and can run anywhere.ĭocker is an ideal solution for MEAN applications. ![]() According to Docker, Docker is an open platform, which enables developers and sysadmins apps to be quickly assembled from components. Both of these offer a ready-made application framework for building MEAN applications.ĭocker has also gained enormous popularity. The two most popular ready-made MEAN application templates are MEAN.io from Linnovate, and MEAN.JS. MEAN web-applications often includes other components, such as Mongoose, Passport, Twitter Bootstrap, Yoeman, Grunt or Gulp, and Bower. MEAN web application’s have four main components, MongoDB, Express, AngularJS, and Node.js. The MEAN stack is a has gained enormous popularity as a reliable and scalable full-stack JavaScript solution. Eliminate potential race conditions between the MongoDB data Docker container and the Node.js web-application container in a ‘Dockerized’ MEAN application.
