![]() ![]() If I want to remove what I’ve been doing and start afresh, all I have to do is stop and remove the containers I’ve been working with. And the best part about my workflow is that I don’t have to install MySQL on my laptop or have numerous schemas floating around. I user Docker (specifically Docker Machine), to spin up clean MySQL instances, and with a few commands have a production-like database to develop against. The MySQL database will be exported to a file named backup. Here is the full command for exporting your database: mysqldump -uUSERNAME -p DATABASE > backup.sql You will be prompted for a password this is your MySQL user’s password. If this sounds like you (as it did me), you’ll be pleased to know there are better ways to manage your development database workflow. To export a MySQL database, use the mysqldump command. Have you ever been developing something for a long period of time, making changes to your development database as you go, and then when you’ve gone to integrate it into staging or production things haven’t quite worked? You’ve had to manually write scripts to ‘fix’ things, or try and get back to your clean development database state by exporting, copying and importing… all manually via your database client? In this post, I’ll show you how I use Docker to create a clean MySQL database that mirrors production each time a start development on a new feature. Using Docker to spin up production-like databases during application development can help take out the uncertainty of whether your changes will work when deployed to production. Check out the post for more information on Docker containers and how they can benefit your organization.Using Docker to spin up databases for development | Tony Wolski Tony Wolski Using Docker to spin up databases for development In our recent post on Docker containers, we explored the benefits of containerization and how it can help organizations achieve faster nodejs development using docker and more efficient application deployment. You can learn more about running your container using a specific user in this blog post and whether you need to run your container as root user or not. In this post, we did not focus on the user you are going to use to run your container. ![]() Now that you have a working database and you can manage the data, you maybe interested in how to setup a remote database to optimize site performance. A good next stop would be to use a continuous integration and continous deployment tool like jenkins. Did anyone make a db backup from docker to host machine I have a MySQL database but I would like to clone it into my real machine because every time I run container it creates a new image, but I want to use this db every time (so I want db to persist in real machine). You can now connect an application to your database. You can now connect to your MySQL container using MySQL workbench. Docker is a set of platform-as-a-service products that support CI/CD development. It stores and structures data in a meaningful manner, ensuring easy accessibility. Now that the container is running, feel free to explore it with the docker exec command. MySQL is a well-known open-source relational database management system and one of the most popular web server solutions. One of this is to host a flask application with one to many relationship. The data inside the database can serve many purposes. If you are using docker-compose prepare your configuration as follows. If you change the port number, make sure you change it in the rest of the commands Step 1: Start your container Case 1: You are using docker-compose ![]() The outside port numbers that I choose to export my mysql service are 330, you can change it if you want. I will use the docker image mysql/mysql-server:5.7 and I will name my container mysql57 to ease my operations. What do we need ?įirst, we will need a running docker container running mysql. The purpose of this tutorial is to share with you how to do it. With my mysql server running in a docker container, I wanted to connect to it and manage it. But how do you manage the data inside that container? You can compose them also inside a container. Some applications like Dolibarr or laravel need a mysql database to run. Running your database inside a container is a very portable solution. Step 6: Connect to MySQL with the workbench.Step 5: Check the status of the users (after config).Step 3.b: Change the password (for fresh installations only).Step 3.a: Check the users in the system.Step 2: Get the mysql generated password.It works, but I dont know the locaation of exported database. Case 2: You run your containers from command line I want to export mysql database in docker. ![]()
