Step-by-Step Guide: Troubleshooting A Failed Deployment Using the Compatibility Matrix
Blog post from Replicated
Replicated's new tool, the Compatibility Matrix (CMX), is designed to facilitate troubleshooting of failed deployments by creating ephemeral Kubernetes clusters. Evans Mungai, Sr. Customer Reliability Engineer, demonstrates its use by replicating customer environments to identify and solve deployment issues, particularly with KOTS applications. The process involves gathering customer information, checking configurations, and employing CMX to create various Kubernetes clusters to replicate the customer's environment and diagnose errors. Once the errors are reproduced locally, solutions can be tested and validated before advising customers. CMX streamlines this process by allowing quick creation and management of clusters across numerous distributions and versions without leaving the command line. The demonstration emphasizes the efficiency and versatility of CMX in resolving complex deployment issues and highlights its potential utility for Independent Software Vendors (ISVs) in supporting their customers.
