GitHub - kubernetes/dashboard: General-purpose web UI for Kubernetes clusters General-purpose web UI for Kubernetes clusters. Contribute to kubernetes/dashboard development by creating an account…github.com kubernetes dashboard is the easiest option to monitor k8s resource usage and under the hood, it is using metrics-server as the data source. so you need to make sure metrics-server has been deployed before looking at graphs/charts in kubernetes dashboard.

I am learning to implement NetworkPolicy in k8s clusters and I learnt something new today. in a k3d cluster, there is a default CNI which supports NetworkPolicy, see https://medium.com/ci-cd-devops/explore-the-cni-option-used-by-k3d-a16b7f48e411 while in a KIND cluster, the default CNI doesn’t support NetworkPolicy, so if you have created a NetworkPolicy in yaml and…

k3d clusters use the Flannel CNI plugin by default (like most clusters) $ k3d cluster create tkb --servers 1 --agents 3 --image rancher/k3s:latest $ k3d node list NAME ROLE CLUSTER STATUS k3d-tkb-agent-0 agent tkb running k3d-tkb-agent-1 agent tkb running k3d-tkb-agent-2 agent tkb running k3d-tkb-server-0 server tkb running k3d-tkb-serverlb loadbalancer tkb running $ docker exec -it k3d-tkb-agent-0 /bin/sh # cd / # find / -type f -name '*.conflist' /var/lib/rancher/k3s/agent/etc/cni/net.d/10-flannel.conflist

minikube, kind, k9s, k3d, AKS, EKS, kops I have been using k8s for few years and currently study to prepare for CKAD certification. Here is some notes I captured for the various k8s tools that I have tried or trying. minikube/kind Minikube is a tool to simulate a single node…

JDK_JAVA_OPTIONS is only picked up by the java launcher, so use it for options that you only want to apply (or only make sense for) the java startup command. This variable is also new on JDK 9+, and will be ignored by earlier JDK versions. Hence, it's useful when migrating from older versions to 9+. JAVA_TOOL_OPTIONS is picked up also by other java tools like jar and javac so it should be used for flags that you want to apply (and are valid) to all those java tools.
