Running databases in Kubernetes has come a long way. In this talk we will discuss challenges and issues as well as opportunities and benefits of doing so as seen in real production use, concentrating on MySQL and MongoDB. Rolling out a database is easy enough, but things can and will get interesting when scaling up and down, or taking and restoring backups. How to find out the last backup is in fact going to restore without issues? We will also look into monitoring the deployment.
Outline:
- Introduction
- Installing
- MySQL in Kubernetes
- MongoDB in Kubernetes
- Scaling up, scaling down
- Backup, restore, verification
- Monitoring (PMM)
- What could possibly go wrong?
Takeaways: This presentation should encourage the audience to embrace possibilities of running databases on Kubernetes, and provide attendees with the “do’s and dont’s” of such a deployment.
