設置環境變量（kubernetes）

對不起，小白的問題，而是從https://github.com/kubernetes/kubernetes/blob/release-1.1/docs/getting-started-guides/logging-elasticsearch.md 它說：設置環境變量（kubernetes）

要使用Elasticsearch和Kibana羣集日誌，你應該設置以下環境變量，如下圖所示：

KUBE_LOGGING_DESTINATION=elasticsearch

在哪裏以及如何設置此Env Var？我在想，我應該使用

gcloud container clusters create

，並通過選項那裏，但沒有options ...

該文件被用戶認爲是通過開源shell腳本進行GCE轉向了集羣。目前不支持Elasticsearch爲羣集創建的一部分，谷歌集裝箱引擎命令。羣集創建完成後，您可以手動將其添加到羣集中。

正如羅伯特的回答已經提到的Elasticsearch/Kibana棧需要在集羣應該在谷歌集裝箱引擎（GKE）運行手動添加。使用這個post給出的信息，我能得到它的工作執行以下步驟：

啓動GKE集羣沒有云的日誌記錄

gcloud container --project <PROJECT_ID> clusters create <CLUSTER_ID> --no-enable-cloud-logging

添加配置fluentd容器各通過使用kubernetes DaemonSet運行節點。

kubectl create -f fluentd-es.yaml

fluentd-es.yaml

apiVersion: extensions/v1beta1 
kind: DaemonSet 
metadata: 
    name: fluentd-elasticsearch 
    namespace: kube-system 
    labels: 
    app: fluentd-logging 

spec: 
    template: 
    metadata: 
     labels: 
     app: fluentd-es 
    spec: 
     containers: 
     - name: fluentd-elasticsearch 
     image: gcr.io/google_containers/fluentd-elasticsearch:1.15 
     resources: 
      limits: 
      memory: 200Mi 
      requests: 
      cpu: 100m 
      memory: 200Mi 
     volumeMounts: 
     - name: varlog 
      mountPath: /var/log 
     - name: varlibdockercontainers 
      mountPath: /var/lib/docker/containers 
      readOnly: true 
     volumes: 
     - name: varlog 
     hostPath: 
      path: /var/log 
     - name: varlibdockercontainers 
     hostPath: 
      path: /var/lib/docker/containers

添加elasticsearch和kibana豆莢和服務。

kubectl create -f es-controller.yaml 
kubectl create -f es-service.yaml 
kubectl create -f kibana-controller.yaml 
kubectl create -f kibana-service.yaml

注意低於該kubernetes.io/cluster-service: "true"標籤（在原始files本）已被刪除。有在定義這個標籤，導致在運行莢終止。

創建kubectl代理
```
kubectl proxy

手錶kibana你的日誌你知道，如果是可以運行的兩個版本fluentd，@哈里哈勒。 1個用於ELK，1個用於GCL。 –
