Docker(三十三)k8s 監控以及容器之間呼叫關係
阿新 • • 發佈:2018-11-22
主要是觀察各個pod 之間的呼叫關係,選用weave-scope
安裝
curl https://cloud.weave.works/k8s/scope.yaml\?k8s-version\=1.8.13 -sL -o scope.yaml
curl https://cloud.weave.works/k8s/scope.yaml\?k8s-version\=1.8.13 -sL -o scope.yaml
curl https://cloud.weave.works/k8s/scope.yaml\?k8s-version\=1.8.13 -sL -o scope.yaml
curl https://cloud.weave.works/k8s/scope.yaml\?k8s-version\=1.8.13 -sL -o scope.yaml
curl https://cloud.weave.works/k8s/scope.yaml\?k8s-version\=1.8.13 -sL -o scope.yaml
curl https://cloud.weave.works/k8s/scope.yaml\?k8s-version\=1.8.13 -sL -o scope.yaml
獲取當前k8s 當前版本的scope 檔案,我用的是1.8.13
檔案內容如下

這裡已經給分配好了namespace,所以直接部署就好
kubectl apply -f scope.yaml
kubectl apply -f scope.yaml
kubectl apply -f scope.yaml
然後分配好ip 地址,自己能訪問到的,如果是公有云,有需要制定k8s 的直接,然後暴露公網地址
