1. Scraping Tekton Metrics Add a ConfigMap configuration file 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 cat <<EOF | kubectl apply -f - apiVersion: v1 kind: ConfigMap metadata: name: config-observability namespace: tekton-pipelines labels: app.kubernetes.io/instance: default app.kubernetes.io/part-of: tekton-pipelines data: metrics.backend-destination: prometheus metrics.taskrun.level: "task" metrics.

1. Why kube-status-metrics is needed Kubernetes monitoring mainly focuses on two kinds of metrics: Basic performance metrics CPU, memory, disk, network, and so on. These can be collected by deploying node-exporter as a DaemonSet and having Prometheus scrape the relevant metrics. Resource object metrics The replica count of a Deployment, the running state of a Pod, and so on.

1. Adding via kubectl create 1 kubectl create secret docker-registry mypullsecret --docker-server=harbor.chenshaowen.com --docker-username=robot-test --docker-password=xxxxxx With kubectl create you can add credentials for pulling images directly. 2. Adding via ~/.docker/config.json Log in to the image registry with an account and password 1 docker login harbor.chenshaowen.com:5000 1 docker login harbor.chenshaowen.com You can add more than one.

1. Global Network Planning Many global, multi-region infrastructures do not put much thought into network planning at the outset. Once the business grows complex enough, they are forced into network adjustments and optimization. Yet any major network change has a huge impact on the business. In the end you are stuck in a dilemma, able to do nothing but invest more people, carry the baggage of history, and walk along the edge of a cliff again and again.

1. Layering of Monitoring As shown above, when building a monitoring system, two strategies are used: Layered monitoring. The benefit of separating IaaS, MySQL middleware, and App layer monitoring is that the systems have high availability and fault tolerance between them. When App layer monitoring stops working, IaaS layer monitoring will immediately make that visible.
