It's easier to manage the containers in your system once you create them (start/stop/restart/delete). And while Kitematic is optional, I recommend you download it, as well.
This will be useful not only for this article but pretty much for everything you will eventually install in the future. If you haven't already done it, make sure you install Homebrew and Cask - package managers for Mac OS. Running RDBMS in containers may not be suited for production, but for development/testing environments, it is the perfect fit. If you really want to make your developer life easier, get used to using Dockerand spinning up databases in containers. In today's containerized world, this is in the past. Sometimes, I'd face problems like dependency hell, conflicts, and missing native libraries, and would eventually end up running the databases in isolated VirtualBox VMs. Now, in the past when I used to run Linux on my laptops, I'd just install each database directly into my environment. If you are beginning your software development career using a Mac and are interested in using relational databases like MySQL/MariaDB, PostgreSQL, Microsoft SQL Server, Azure CosmosDB SQL, or Oracle Database, then this article is for you!
