Continuous Integration and Delivery with Docker


The continuous integration setup consists of:

  • running unit tests
  • building the image that we use to build our service
  • running the build container and compiling our service
  • building the Docker image that we run and deploy
  • pushing the final image to a Docker registry

Continuous delivery is all about reducing risk and delivering value faster by producing reliable software in short iterations.

Let’s take a Hello World web server written in Go as an example service. You can find all the code used in this example here: ://

5 tips to be a Better Programmer


Here are five tips to be a better programmer.

  1. Coding is a craft; you learn it by doing it. That is why training courses have such a strong practical element. It is also a skill that is easy to forget, so use it or lose it.
  2. Even when familiar with the basic constructs, it is still worth fully understanding the detailed syntax of the language you are using. Languages contain many subtleties.
  3. Learn some theory and then do some practical. First gain a good understanding of the principles, purpose and limits of a new technology. Next, start to build an application using the technology.
  4. Many developers start to build something, and may even get it to work, without really knowing what exactly they are doing, or why. That is why having a good understanding is important. With software development, theory and practice go hand in hand.
  5. For the practical bit, it is fine to start by copying code or following step-by-step instructions. But then try, by yourself, building a program from scratch. That is when you really get a sense of achievement.
