Part of the official requirements for Kubernetes is to disable swap space completely before attempting to launch Kubernetes. In some recent patch notes, Kubernetes has begun implementing support for swap space in some scenarios, but it is not fully supported. The official reason for not supporting swap space is because it is hard to predict how a pod might utilize memory when swap is enabled.

Every Linux system imposes some upper limit on the number of files that can be opened simultaneously. If you exceed this limit, you will encounter the
Too Many Open Files error. This is a security feature and failsafe to keep the system from becoming overwhelmed, since opening thousands of files is ordinarily unnecessary and indicative of a program gone haywire or a malicious user trying to crash the system.
If you receive the
Permission Denied error on your Linux system, it usually means that your user account does not have the proper permissions on the file or directory you are trying to interact with. All files and directories in the Linux file system have user and group permissions attached to them that delegate access to read, write, or execute the file. These permissions work independently of each other, so just because you are able to open a file, does not mean you can edit it.
