Resolve redirection internally from upstream - Nginx.

Run NetBox on Rancher - Docker Compose.

If you manage many of dedicated servers and networks, you will need a "Source of Truth" to do that efficiently. From time to time I try to find a better solution to do that.

However you still can get the same functionality on Linux using

Continuous integration tools and best practices - DevOps.

I'm always interested in improving the way I do things, so I love to learn new technologies, go with new challenges ... and most important thing, I don't believe in "If it's not broke, don't fix it"! I always review and re-evaluate how I do things!
