Docker

In this post, we will learn how to set up a MongoDB replica set using Docker. We will also learn how to use docker-compose to automate this process. When storing data in MongoDB, we can have multiple Mongo servers (called replicas) that hold a copy of the stored data. This way, even if one of the servers goes down, we have a backup to retrieve data from. This technique is used to make applications more resilient to database failures, since the application can keep running even if a single database server fails....

This post is going to describe how to build applications using the BusyBox docker image, along with a sample web server that we will run using BusyBox as the base. You can see the sample code for this post on Github What Is BusyBox? From it’s own webpage: BusyBox combines tiny versions of many common UNIX utilities into a single small executable. The BusyBox Docker container gives us an image many times smaller than, for example, the Ubuntu image:...
