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
• MySQL on Docker: ProxySQL Native Clustering with Kubernetes

Here are some examples of ProxySQL configuration:

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