We currently have a bunch of apps that we are trying to convert from VMs to containers running in Kubernetes. A lot of these apps read/write to a windows drive. So when moving these apps to kubernetes we have created a cluster level PV that references the windows drive. Now here is where I get confused. I am reading the following on chatgpt: "In Kubernetes, a Persistent Volume (PV) can indeed only be bound to one Persistent Volume Claim (PVC) at a time. Once a PVC is bound to a PV, it effectively "locks" the PV to that PVC until the PVC is released or deleted." So what we have done is created ..read more

Hello everyone, I am trying to configure a thing that collects logs, metrics and potentially traces into something, so I can review that later. Reading on the topics, it seems like there are several solutions and OpenTelemetry seems like the good choice. It several articles I saw that people use fluentbit to collect telemetry, so they can later send it to otel. I am still starting with the topic and confused why one would need fluentbit + otel collector, where it seems like otel collector does roughly the same thing as fluentbit. The only thing I can think of is that fluentbit seems to be a b ..read more

I noticed that when I do a port-forward in a minikube cluster/profile, then switch profiles, I don't have to do the port-forwarding again. I am wondering what is the mechanism behind that, how does it keep the connection alive when the profile is changed? Thanks submitted by /u/National-Evidence-79 [visit reddit] [comments ..read more

I had a typo in a helm values.yaml. Precious time got wasted because of that. The typo was in a key name. Is there a way to detect keys which don't exist? If a apply yaml with kubectl, typos get detected. submitted by /u/guettli [visit reddit] [comments ..read more

Hi guys, I have a next.js frontend, golang rest api server and a go worker. Users can submit jobs that take around 10 second to complete. The rest api exposes a status endpoint and the frontend polls it. I am trying to move away from polling to server sent events. I created a new server which accepts long connections from frontend using EventSource API. The go worker calls this sse server and the sse server looks up the user channel and sends emits an event. This is good as long as I only have one SSE server. As it scales to more than one instance, the go worker sends an event and it might no ..read more

I'm not able to find an answer to this online, so apologies if this is a daft question. I have a base image which is my main application, and then I have smaller bits which are sort of rules files which are built and deployed using the base image as well, the base image. I therefore run about 100 instances of my main application, but each with a few different plugins and rules files. If I run one instance of one of these in docker locally, it takes up about 200mb of memory. If I run more, is the shared memory portion shared at all between them? Or would it actually be 200mb of distinct memory ..read more

Hi I'm trying to setup a k0s cluster in an I guess unusual setup. There are several PCs/VMs on different locations connected together over wireguard to reach a somewaht local area network in which I want to operate the cluster. The reason for wireguard is, that most of the nodes are behind a NAT and so it was a convinient way to to get everything connected. But know I want the services reachable over the internet (or at least the allowed IPs) and thats where I begin to struggle. There is at the moment one VPS with a public IP which I thought should be the entry point. But how do I proceed kno ..read more
