kubernetes设置所有物理节点的列表
我已经按照以下步骤设置了Kubernetes。 一切看起来都不错 – 但它运行在单个节点/服务器上。
现在我想要在多个节点上运行下一步。 我想知道我应该在哪里configuration我的物理服务器的ip，所以我可以在多个物理服务器上创buildpod。
我运行：
hack/local-up-cluster.sh 然后（在另一个terminal）：
cluster/kubectl.sh config set-cluster local --server=http://127.0.0.1:8080 --insecure-skip-tls-verify=true cluster/kubectl.sh config set-context local --cluster=local cluster/kubectl.sh config use-context local
和：
cluster/kubectl.sh create -f run-aii.yaml
我的跑步aii.yaml：
apiVersion: extensions/v1beta1 kind: Deployment metadata: name: aii spec: replicas: 1 template: metadata: labels: run: aii spec: containers: - name: aii image: localhost:5000/dev/aii ports: - containerPort: 5144 env: - name: KAFKA_IP value: kafka volumeMounts: - mountPath: /root/script name: scripts-data readOnly: true - mountPath: /home/aii/core name: core-aii readOnly: false - mountPath: /home/aii/genome name: genome-aii readOnly: true - mountPath: /home/aii/main name: main-aii readOnly: false - name: kafka image: localhost:5000/dev/kafkazoo volumeMounts: - mountPath: /root/script name: scripts-data readOnly: true - mountPath: /root/config name: config-data readOnly: true volumes: - name: scripts-data hostPath: path: /home/aii/general/infra/script - name: config-data hostPath: path: /home/aii/general/infra/config - name: core-aii hostPath: path: /home/aii/general/core - name: genome-aii hostPath: path: /home/aii/general/genome - name: main-aii hostPath: path: /home/aii/general/main - mountPath: /home/aii/main name: main-aii readOnly: false - name: kafka image: localhost:5000/dev/kafkazoo volumeMounts: - mountPath: /root/script name: scripts-data readOnly: true - mountPath: /root/config name: config-data readOnly: true volumes: - name: scripts-data hostPath: path: /home/aii/general/infra/script - name: config-data hostPath: path: /home/aii/general/infra/config - name: core-aii hostPath: path: /home/aii/general/core - name: genome-aii hostPath: path: /home/aii/general/genome - name: main-aii hostPath: path: /home/aii/general/main

听起来你想要build立一个多节点集群，有很多方法可以做到这一点（ http://kubernetes.io/docs/getting-started-guides/ ）。
如果你想在你的机器上使用本地解决scheme，那么无用的方式或者docker的方式非常简单。
如果要查找云，那么GCE是下一个最简单的（ https://cloud.google.com/container-engine/ ）。
一旦完成了多节点集群的设置，那么当您部署pod时，它将被安排到集群中的一个节点。
在上面给出的清单中，唯一需要注意的是，您是否正在使用HostPaths进行所有卷装载。 当你知道什么机器在运行时，这很好，但是，你应该把自己从这个抽象出来。
为了更好地解决问题，您需要查看一些不是主机特定的持久性卷。 但现在，你可以得到它的工作。 =）
