Yesterday’s Friday 13^th proved to be a lucky day for me as I became a Certified Kubernetes Application Developer (CKAD).

For those not familiar with Kubernetes (K8s), it’s the most popular and advanced platform for cloud deployments. It’s been initially developed by Google, and is used in nearly every mature cloud these days.

It also runs our once.to URL shortener, by the way.

Kubernetes is an awesome platform: powerful, flexible, and — last but not least — open-source.

But back to the certification: as always, there are nuances, which I’d like to share with you, hopefully they can be of use.

My current project makes use of the MySQL database, which runs in a Docker container.

At a certain moment connecting to the database became excruciatingly slow, taking tens of seconds to establish a single connection. After that everything would work as expected.

The application opens a connection some hundred times, so the startup time had become really unacceptable.

I’ve spent a lot of time hunting that down, and then even more time looking for a solution as I failed to find any on StackOverflow. But finally I’ve solved this.

It’s been about a year since I’ve switched to developing this website (built with Yii 2/PHP/MySQL) using Docker. After just one try I realised that Docker is the best thing happened to development. Well, after Vim, of course.
