What happens if you change sysctl from inside a pod?
You cannot modify any sysctl setting from a pod that doesn’t run under privileged
security context. You would see Read-only file system
error.

My USB/wireless printer worked fine for 10 days and then stopped working.
Print jobs are queued but are not printed and even CUPS doesn’t detect the printer anymore. After looking at the logs at /var/log/messages
,
it appears that the printer was constantly getting disconnected.
I have an old HP 1018 USB printer at home. It has been serving well for 10 years and is still going strong. Back then we had just one computer at home - a desktop computer which was shared by everyone. Now everyone has their own smartphones desktop/laptops but there is only one printer. Time has come for the printer to be available wirelessly on the network. As a temporary solution, I have connected the printer to the desktop and enabled printer sharing so that any device connected to the same home wifi can use the printer. But the desktop has to be always on which is cumbersome and also increases the electricity bill. Following are the approaches I considered for solving this.
MetalLB is a load-balancer implementation for
bare metal Kubernetes clusters. I’ve used it succesfully to add support for
LoadBalancer
type service on bare-metal kubernetes clusters to expose my
services outside the cluster.
Exposing services externally on Kubernetes clusters provided by cloud providers
is as simple as setting spec.type
as LoadBalancer
in the service
specification and the cloud provider takes care of spinning up a network load
balancer. It is not that simple on bare metal Kubernetes clusters as there is no
support for LoadBalancer
service out of the box as of today. I had this
problem recently at work and figured out few approaches to deal with this after
some google-fu and researching on how IngressControllers like nginx deal with
it.
