One of the most common K8s failures is the Out of Memory (OOM) Killer. This happens when your container exceeds its allocated limit. Type Definition Requests What the pod is guaranteed to have. Limits The absolute maximum the pod can consume. Pro Strategy: Always set requests equal to limits for memory to avoid unstable rescheduling […]
XML-RPC is an old API used for remote access. Today, it’s mostly a target for hackers to try thousands of password combinations in a single request. How to Disable: Paste this into your .htaccess file: Order Deny,Allow Deny from all This simple block reduces server load and significantly hardens your security wall.
