Configuring MySQL in a Docker Container

In recent weeks I’ve been focusing on Docker in order to get a much better understanding of the containerized world that is materializing in front of us. Containers aren’t just for stateless applications anymore and we’re seeing more cases where MySQL and other databases are being launched in a containerized fashion, so it’s important to know how to configure your MySQL container!

In docker hub, you will see an option for this by doing a volume mount from the docker host to the container on /etc/mysql/conf.d. But the problem is that the container image you’re using may not have an !includedir referencing the conf.d directory, much like the latest version of mysql community, as you will see below.

Deploying PMM on Linode: Your $5-Per-Month Monitoring Solution

In this blog, I will show you how to install PMM on Linode as a low-cost database monitoring solution.

Many of my friends use Linode to run their personal sites, as well as small projects. While Linode is no match for Big Cloud providers in features, it is really wonderful when it comes to cost and simplicity: a Linode “nanode” instance offers 1GB of memory, 1 core, 20GB of storage and 1TB of traffic for just $5 a month.

A single Linode instance is powerful enough to use with Percona Monitoring and Management (PMM) to monitor several systems, so I use Linode a lot when I want to demonstrate PMM deployment through Docker, rather than …

Manage Your MySQL Database Credentials with Vault

Any software system requires secrets to run, be it credentials to communicate with databases, tokens to access resources, or encryption keys that need to be distributed. Secrets management means to deal with all kinds of secrets in a structured and secure way. In this blog entry we will show how to use Hashicorp Vault to […]

Authenticating Vault Against LDAP for Accessing MySQL Through ProxySQL

Earlier this year, I was presented with the challenge of streamlining user access to MySQL, allowing users self-serve access using their LDAP credentials, while logging all access. Of course, various MySQL forks allow for user auditing, but the solution is also needed to eventually support other data storage systems without native user auditing. This gave me the opportunity to do a trial integration of MySQL, Vault, ProxySQL, and LDAP; Vault would be used to dynamically create user accounts, and ProxySQL would be used to limit access and log activity. To evaluate the functionality and configuration of the integration, I used Docker to set up a test environment.

Below I will present the methods used to:

  1. Provision the Docker environment.
  2. Configure OpenLDAP.

Test MySQL 8.0 right in your computer

MySQL 8.0 GA is right around the corner. I don't have precise information about its release, as I don't work at Oracle. If I did, I would probably know, but I couldn't tell when the release is scheduled to appear because of company policies. I can, however, speculate and infer, based of my experience with previous releases. My personal assessment is that the release will appear before 9:00am PT on April 24, 2018. The "before" can be anything from a few minutes to one week in advance.
Then, again, it may not happen at all if someone finds an atrocious bug that needs to be fixed asap.

Either way, users are keen on testing the new release in its current state of release candidate. Here I show a few methods that allow you to have a taste of the new …

Docker Compose Setup for InnoDB Cluster

In the following we show how InnoDB cluster can be deployed in a container context. In the official documentation (Introducing InnoDB Cluster), InnoDB is described as: MySQL InnoDB cluster provides a complete high availability solution for MySQL. MySQL Shell includes AdminAPI which enables you to easily configure and administer a group of at least three […]

HashiCorp Nomad and App Deployment with MySQL

We started our series on MySQL Docker deploments by showing how to deploy and use MySQL locally with docker-compose in Docker Compose and App Deployment with MySQL. Docker-compose itself is limited to one machine and it does not solve cross-node networking or span multiple datacenters. This is a job for so called cluster schedulers, i.e. […]

Docker Compose and App Deployment with MySQL

In this post we show how to use the mysql-server Docker image for local development. We first introduce a simple example app that starts up and tries to connect to a given db until successful. We then show how to start containers for multiple MySQL versions and use our example app to connect to them. […]

Percona Live Europe Session Interview: MySQL on Docker – Containerizing the Dolphin

One of the widely discussed technologies at Percona Live Europe was the logistics of running MySQL in containers. Containers – particularly Docker – have become a hot topic, so there was a good-sized crowd on day one of the conference for Ashraf Sharif, Senior Support Engineer with Severalnines. He presented his talk “MySQL on Docker: Containerizing the Dolphin”. 

During his presentation, Ashraf shared some recommendations for best practices when setting out on containerizing MySQL. He sees the trend of moving to containers as a progression from the use of virtual hosts.

After his talk on day one of the Percona Live Europe conference, I caught up with Ashraf and asked about his presentation. I was interested in which concepts are most important for …
