On Unix, MySQL programs treat the host name localhost specially, in a way that is likely different from what you expect compared to other network-based programs: the client connects using a Unix socket file. It turns out, MySQL has a unique definition of localhost ( docs). When you try to create the MySQL databases for your Rails project by running commands like rails db:setup, you may still get an error like this: Mysql2::Error: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2). Whenever you need to switch versions, you can just stop the running container as shown in step 3, and start the necessary container by docker start or the start button in the dashboard.ĥ. The tag (version) you need, like mysql:5.6 (list of available tags here)Īnd voila! You have two versions of MySQL now (you can check via docker ps/dashboard).You can use the same command as step 2 to boot up containers for other versions of MySQL. Start another Docker container (MySQL version: 5.6) Note: If you try to start another container mapped to port 3306 without stopping the current one, you will get this error: Bind for 0.0.0.0:3306 failed: port is already allocated.Ĥ.

So first, let's stop the currently running container to free up the port (you can restart this container later).įrom the command line: docker stop (use the name you specified under -name)įrom the Docker Desktop dashboard: Click the stop button

But you can't run two containers mapped to port 3306 at the same time. Using the command in step 2, now you can boot up any other MySQL containers you need. You can also check from the Docker Desktop dashboard:ģ.

Let's boot up a container with the latest version of MySQL first.įor any Docker beginners out there, docker run creates a new container with the specified image ( mysql:latest in this case) and runs it.Įnter fullscreen mode Exit fullscreen mode Start a Docker container (MySQL version: latest) After it's installed, you can find it under ~/Applications.Ģ.

Install Docker Desktop if you haven't yet. Start another Docker container (MySQL version: 5.6).Stop the container to free up port 3306.Start a Docker container (MySQL version: latest).Also, no worries if you're not familiar with Docker commands :) I provided explanations for the command options to make this as beginner-friendly as I could.įor the purpose of this guide, let's say you're trying to use the latest version of MySQL and version 5.6. This guide walks you through setting up Docker containers for different versions of MySQL, and the necessary Rails configuration (only the last part is Rails-specific). But it's actually very straightforward and easy to use, so I highly recommend it if you need multiple versions of MySQL. I am no Docker expert, and it took some time to figure out. Installing both versions using Homebrew and doing brew switch turned out to be a nightmare, so I decided to use MySQL on Docker. But I'd already been using MySQL 8 (the latest version as of this writing) for a different project, installed locally via Homebrew. Recently, I joined a Rails project that requires MySQL 5.6.
