Activate dashboard you cluster
In order to make it more convenient to monitor the state of the cluster, it is possible to activate 2 types of dashboard The address where the dashboard will be available https://dashboard.you-base.domain
- A simpler one that does not require additional configuration is Kube dashboard To access the panel, you need to get a secret for this, while in the cluster, run:
kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep admin | awk '{print $1}')`
- More flexible and professional Grafana tool it will additionally install Prometheus and Loki to cover basic administration needs. Grafana by default does not carry ready-made dashboards, the user himself must configure it to suit his needs To start, we recommend that you import your dashboard using the code 7249
Example config
Kube dashboaerd
metrics:
kubedashboard:
enable: true
url: you-base.domain
Grafana + Prometheus + loki
metrics:
grafana:
enable: true
username: ""
password: ""
url: you-base.domain
Installing Weave Scope
Weave Scope tool for quick analysis of cluster health to activate it follow
kubectl apply -f "https://cloud.weave.works/k8s/scope.yaml?k8s-version=$(kubectl version | base64 | tr -d '\n')"
kubectl port-forward -n weave "$(kubectl get -n weave pod --selector=weave-scope-component=app -o jsonpath='{.items..metadata.name}')" 4040
after analysis, you can delete this dashboard
kubectl delete ns weave
Installing Telegram Alerts
In order to receive messages about the status of the cluster in the chat with the project or in person, you must:
- register a bot through BotFather
- using the @RawDataBot bot to get the ID of a personal chat or a group
- create a separate namespace in the kubectl cluster create ns alert
- launch the bot with execution
kubectl --namespace alert run kubewatch --image xxxvikxakerxxx / telegramalert: 0.0.1 - --telegramapi = "" --telegramgroup = "" pods
