尝试部署heapster-controller以使Heapster + Graphana + InfluxDB适用于Kubernetes。尝试使用heapster-controller.yaml文件进行ot部署时获取错误消息:
heapster-controller.yaml apiVersion: extensions/v1beta1kind: Deploymentmetadata: name: heapster-v1.1.0-beta1 namespace: kube-system labels: k8s-app: heapster kubernetes.io/cluster-service: "true"spec: replicas: 1 selector: matchLabels: k8s-app: heapster template: metadata: labels: k8s-app: heapster kubernetes.io/cluster-service: "true" spec: containers: - image: gcr.io/google_containers/heapster:v1.1.0-beta1 name: heapster resources: # keep request = limit to keep this container in guaranteed class limits: cpu: 100m memory: 200m requests: cpu: 100m memory: 200m command: - /heapster - --source=kubernetes.summary_api:'' - --sink=influxdb:http://monitoring-influxdb:8086 - --metric_resolution=60s - image: gcr.io/google_containers/heapster:v1.1.0-beta1 name: eventer resources: # keep request = limit to keep this container in guaranteed class limits: cpu: 100m memory: 200m requests: cpu: 100m memory: 200m command: - /eventer - --source=kubernetes:'' - --sink=influxdb:http://monitoring-influxdb:8086 - image: gcr.io/google_containers/addon-resizer:1.0 name: heapster-nanny resources: limits: cpu: 50m memory: 100Mi requests: cpu: 50m memory: 100Mi env: - name: MY_POD_NAME valueFrom: fieldRef: fieldPath: metadata.name - name: MY_POD_NAMESPACE valueFrom: fieldRef: fieldPath: metadata.namespace command: - /pod_nanny - --cpu=100m - --extra-cpu=0m - --memory=200 - --extra-memory=200Mi - --threshold=5 - --deployment=heapster-v1.1.0-beta1 - --container=heapster - --poll-period=300000 - image: gcr.io/google_containers/addon-resizer:1.0 name: eventer-nanny resources: limits: cpu: 50m memory: 100Mi requests: cpu: 50m memory: 100Mi env: - name: MY_POD_NAME valueFrom: fieldRef: fieldPath: metadata.name - name: MY_POD_NAMESPACE valueFrom: fieldRef: fieldPath: metadata.namespace command: - /pod_nanny - --cpu=100m - --extra-cpu=0m - --memory=200 - --extra-memory=200Ki - --threshold=5 - --deployment=heapster-v1.1.0-beta1 - --container=eventer - --poll-period=300000
部署已经完成，但随后出现错误:[root@node236 influxdb]# kubectl get pods -o wide --namespace=kube-systemNAME READY STATUS RESTARTS AGE NODEheapster-v1.1.0-beta1-3082378092-t6inb 2/4 RunContainerError 0 1m node262.local.net[root@node236 influxdb]#
显示失败容器的日志:[root@node236 influxdb]# kubectl logs --namespace=kube-system heapster-v1.1.0-beta1-3082378092-t6inbError from server: a container name must be specified for pod heapster-v1.1.0-beta1-3082378092-t6inb, choose one of: [heapster eventer heapster-nanny eventer-nanny][root@node236 influxdb]#
我可能在哪里出错？

最佳答案
正确的语法是kubectl logs <pod> <container>。
在您的示例中，kubectl logs heapster-v1.1.0-beta1-3082378092-t6inb heapster --namespace=kube-system将显示命名容器内“heapster”容器的日志。
