You might have noticed that I’m doing quite a bit of Docker related articles lately. This is because I’ve been exploring it as an option for the future of my personal web applications. As of right now I’m serving several web applications on Digital Ocean under a single Apache instance. As requests come into my server, Apache routes them to the appropriate application via virtual hosts. Each application is a different directory on the virtual private server (VPS). If I were to containerize each application, things would behave a bit differently. I would need to set up a reverse proxy to route each request to a different container on the host.
While Apache can work as a reverse proxy, there are other options that work way better. For example NGINX is known for being an awesome reverse proxy solution. We’re going to see how to create several web application containers and route between them with an NGINX reverse proxy container.

So how do you connect to a detached container that is already running? We’re going to take a look at how to do this with minimal effort.
Read MoreRecently I’ve been using a good amount of Docker for various deployment pipelines. As everyone knows, I’m a huge Raspberry Pi fan, so I figured it would be a cool idea to bring the two together. After all, Docker was built using Golang which is cross architecture.
We’re going to see how to create Docker containers on a Raspberry Pi and figure out the limitations of using Docker on IoT based architectures.
