I have been a hardcore CentOS user for many years now. I enjoyed its minimal install to create a light environment, intuitive installation process, and it’s package manager. Docker is the most popular container format today and provides developers and enthusiasts with an easy way to run workloads in containerized environments. I started using Docker in production at home for about a year now for services such as Plex Media Server, Web Server for this blog, ZNC, MineCraft, and MySQL to name a few. A Dockerfile is a set of instructions used to create a Docker image. I invested many hours creating perfect Dockerfiles using CentOS and Fedora to make deployments simple on any operating system. However, a personal revolution was brewing.
AT&T is moving away from proprietary systems and stepping toward Canonical Ltd.'s open-source operating system Ubuntu.
Canonical announced the news in a blog post, saying it is joining forces with AT&T to provide its Ubuntu OS and engineering support for the carrier's cloud, network and enterprise applications.
The companies disclosed that the partnership is significant in coming up with Ubuntu-based apps across the internal and external systems of AT&T.
