traefik-dockerized VS docker

In previous post, we discussed creating a basic Nomad cluster in the Vultr cloud. Here, we will use the cluster created to deploy a load-balanced sample web app using the service discovery capability of Nomad and its native integration with the Traefik load balancer. The source code is available here for the reference.

Yes, there's a small downtime when I deploy the app, but I am considering using Traefik to hold requests while the new build is up and running and ready to accept incoming requests.

I have seen / heard good things abut Traefik [Traefik site] but not used it .

I like Traefik for exactly this. Best part: you can define all the mappings with labels in the compose file.

During specific use cases, I sometimes encounter issues with port forwarding that force me to get back to my laptop’s keyboard, for example when using Docker with Traefik, VS Code is sometimes confused about what port to forward and where to forward it to.

6. Docker

An open-source platform called Docker was created to automate application deployment, scaling, and management.

Docker: Download and install Docker from Docker's official website.

Docker - A platform for developing, shipping, and running applications. Docker Documentation - Official documentation.

There are several container runtimes in the industry today. We chose to use Docker as it seems to be the industry standard, especially on a Mac. Docker is also well documented, and thus should be the easiest to learn. Although, I am concerned because I've heard the runtime is a bit greedy with CPU and memory resources. I hope this Old Box can handle it.

Docker has revolutionized the way we build, ship, and run applications. In this article, we’ll explore the most useful Docker commands every developer should know.

On my Mac, I have installed Docker and deployed several applications within their containers. I don't need to access these applications over the Internet, so I keep them local, accessing them with my browser using localhost and their exposed ports.

Containerization with Docker can be slow to start if you are learning, but once you have it down containerizing each micro-service will come pretty quickly.

Docker is an open-source platform that uses containerization technology to make it easier to create, deploy, and run applications by using containers. Containers allow a developer to package up an application with all of the parts it needs, such as libraries and other dependencies, and ship it all out as one package.
