![]() ![]() If you take a peek at the db/mysql8/init you’ll notice the initializer also added a 01.sql file. The initializers have created a folder PER DB inside, each with a data folder, init folder, and for MySQL a my.conf file. Let’s take a look at what happened: You should now see a db folder. initializers permissions and runs each DB initializer file respectfully to scaffold out or db folder. You may need to ensure setup.sh has executable permissions by running chmod +x.run docker-compose config to ensure your ENVs are pulling through.env.example and set your DB ENVs accordingly. We are leveraging Docker/MySQL and Docker/Postgres docs here. This setup will enable you to set up and run, MySQL 5.6, 5.7, 8, and Postgres either as a suite or as individual services (recommended). Note: If you are familiar with docker and want a single instance of a DB feel free to take a quick peek at the docker-compose.yml and copy over what you need. If we need to tweak a config, it’s as easy as stopping the running container, editing/creating a file and restarting. ![]() This also lends itself to expansion with other DB tooling, postgres, redis, and memcache for example. Each instance is self contained to it’s container with a persisted volume and config files are set for each as needed. ![]() The main focus here is to give each DB instance a home, MySQL 5.6 shouldn’t care about MySQL8, etc. And what if you need to modify some my.cnf files? While services have options, and there are definitely pro’s and con’s to both, having more direct control over what is going in our dev setup can be ideal when onboarding and debugging various applications. At some point, however, you’ll want more direct access to logging, and those free services and hosts stop being free. Slap that MySQL instance up there and drop some ENVs. Why can’t we just host these in the cloud somewhere?! Absolutely, this is not to discourage other alternatives. Have you ever tried to manage 3 versions of MySQL on a mac? While you can brew link all day… they still share common MySQL setup files and config files via brew… and as you could imagine, and MySQL8 do not play nice together. The same reason you use docker for anything, projects differ, and while version managers work well for programming languages, they are nightmarish for databases. Note: don't forget to change root password.Below is an exported README from a current docker setup for database versioning.įeel free to clone and follow along in exploring this probably over-engineered setup. docker network create app-net docker run -d -name=percona-mysql -restart=always -network=app-net \ By default, Percona Server for MySQL service is listening on port 3306. User-defined bridge network can be used for listening on different port. v /opt/percona-mysql/logs:/var/log/mysql \ v /opt/percona-mysql/data:/var/lib/mysql \ Run the following command to create a container for Percona Server for MySQL that uses host network: docker run -d -name=percona-mysql -restart=always -network=host \ The mysql user will be created in the container. Note: it doesn't matter that mysql user doesn't exist on host system. Set mysql user (ID: 1001) as owner for newly created directories: sudo chown -R 1001:1001 /opt/percona-mysql Install Percona Server for MySQLĬreate directories for data and logs: sudo mkdir -p /opt/percona-mysql/ If you are using Ubuntu, installation instructions can be found in the post. Make sure you have installed Docker in your system. This tutorial explains how to install Percona Server for MySQL inside a Docker container in the Linux. It also provides enhanced features for performance. All the functionality of MySQL are available in the Percona Server for MySQL. Percona Server for MySQL is a fully compatible drop-in replacement for MySQL. Percona Server for MySQL is a relational database that allows to access data using Structured Query Language (SQL). ![]()
