Please could someone tell me where to get release notes for microk8s snap updates which are patch/bugfix versions. On the Releases · canonical/microk8s · GitHub release notes page you only get information about the main releases, e.g. 1.27, 1.28 There are reasonably regular patches - e.g. 1.28.6 to 1.28.7 just out. Where are the release notes for these? 1 post - 1 participant Read full topic ..read more

When the k8s controller assigns a random nodeport port, will it skip ports already in use in custom nodeports?
Discuss Kubernetes Forums

I’m first going to describe the background of the situation, and I have a question at the end. We have several clusters running Kubernetes 1.24 (recently upgraded from 1.13). In those clusters, our services are NodePort services (we’re considering changing, but that’s down the road). This will result in a random port being assigned for the “http” and “https” nodeport, in the range from 30000-32767. This is all fine. Some of our services define “custom” nodeport entries for various reasons. They use a hardcoded port number in those cases. I’ve noticed that some of those services have used a por ..read more

Can I limit what sources can use a service account by IP?
Discuss Kubernetes Forums

The story is, my boss want to reduce the risk of attackers taking advantage of super privileges service account. Since we will create a SA called cluster-admin and use it to control our K8S, my boss ask me to find a way, to achieve that only some IP sources (our bastion servers, for example) can use the cluster-admin SA. Is it possible? Since now I haven’t found related knowledge, thank you. 1 post - 1 participant Read full topic ..read more

Egress with encryption
Discuss Kubernetes Forums

Hi - This is a technical question and I am wondering how to achieve it. I have two Kubernetes clusters. I would like to set up a tunnel between the two clusters using stunnel in one side and nginx in the other. All TCP traffic going out of the first cluster will need to transit through stunnel. This TCP traffic will be encrypted using stunnel and then offloaded at the nginx ingress controller of the destination cluster. I would like some guidance on how to achieve the egress tunnel. i.e. How to configure stunnel “service” to tunnel traffic from one cluster to another cluster. Thank you 1 post ..read more

Spring Boot logs not showing in kubectl logs
Discuss Kubernetes Forums

I’m running a Spring Boot app in Minikube v1.32.0. The minikube is running in WSL with the Docker driver, and my host machine is Windows 10. The app loads fine without any pod restarts. The issue is, that none of my logs are visible in the output of kubectl logs, only logs of the framework itself (which look valid): When running the app on localhost, or simply in Docker, I can see all my logs, so this is clearly an issue specific to k8s. For example, here’s a snippet from my code. Neither slf4j nor System.out.println print anything: package com.mathportal.gateway; import org.slf4j.Logger; i ..read more
