Using The Docker Client With A Remote Machine Or Virtual Private Server

Not too long ago I wrote about containerizing a bunch of web applications and putting them behind an NGINX reverse proxy. This is because I’ve been exploring the possibility of taking all my personal applications and turning them into Docker containers for easy maintenance and portability. I currently use Digital Ocean and if I had to guess, I’m going to be using it for a lot longer as it is a great service. So what does it take to get containerized applications on Digital Ocean or any other remote machine?

We’re going to take a look at creating and defining a remote machine in Docker and deploying containers on it.

Use NGINX As A Reverse Proxy To Your Containerized Docker Applications

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.
