Docker is a great way to run web applications and services in a container. With Docker, each container is isolated from the host which encourages composability and greatly improves security. In this article, I will describe how I prepared a number of services to run in Docker on one of my servers.
With CGO_ENABLED=0 set, the Go compiler produces binaries with no runtime dependencies, not even libc. This greatly simplifies deploying the application in Docker since no base image is required. However, there are a few caveats and pitfalls that I would like to address in this article.
In an attempt to better understand the effect of temperature and humidity in weather forecasting, I decided to build a small thermometer with an Arduino and a temperature sensor. In a future article, I will explore some of the data that I capture and the software that analyzes the data. This article will focus on the thermometer.
