Example Configurations, proxysql.cnf

For Kubernetes, check out the following blog posts for explanation and examples:

• MySQL on Docker: Running ProxySQL as a Helper Container on Kubernetes
• MySQL on Docker: Running ProxySQL as Kubernetes Service

Here are some examples of ProxySQL configuration:

• Galera (ProxySQL 2.x) with web stats port 6080
• Galera (ProxySQL 1.x)
• MySQL Replication

For greater detail and explanation, check out How to Run and Configure ProxySQL 2.0 for MySQL Galera Cluster on Docker.

You can also find some examples of proxysql.cnf in the official repository: https://github.com/sysown/proxysql/blob/master/doc/configuration.md
