Description
The primary purpose of this repository is to share the instructions how to deploy and configure a mysql instance in the cluster with persistent storage.
It is recommended to use the pre-defined helm chart for this. There is a set of customisations that we need to apply and this is why I've prepared the customised values.yaml
The following default values were updated:
- mysqlRootPassword
- mysqlUser
- mysqlPassword
- mysqlDatabase
- configurationFiles.mysql.cnf
- metrics.enabled
- metrics.annotations
- metrics.flags
Most of these changes can be provided using --set argument, but I'm not really sure how to provide metrics.annotations and configurationFiles.mysql.cnf.
The metrics.annotations is required to run the mysqld-exporter container in the pod to export metrics into Prometheus.
Custom mysql.cnf is required to enable slow_query_log.
Installation
helm install mysql-sample -f values.yaml stable/mysql
