HELM_VERSION=${K8S_VERSION:-"2.11.0"}
HELM="helm-v${HELM_VERSION}-linux-amd64"
curl -L https://storage.googleapis.com/kubernetes-helm/$HELM.tar.gz -o $HELM.tar.gz
tar -xvzf $HELM.tar.gz -C /tmp
mv /tmp/linux-amd64/helm /usr/local/bin/helm
2、验证安装
helm version [apps@mvxl1484 ~]$ helm version Client: &version.Version{SemVer:"v2.11.0", GitCommit:"2e55dbe1fdb5fdb96b75ff144a339489417b146b", GitTreeState:"clean"} Error: could not find tiller
3、安装tiller。首先搜索tiller
docker search tiller [apps@mvxl1484 k8s]$ docker search tiller NAME DESCRIPTION STARS OFFICIAL AUTOMATED sapcc/tiller Mirror of https://gcr.io/kubernetes-helm/t... 5 jessestuart/tiller Nightly multi-architecture (amd64, arm64, ... 4 [OK] ist0ne/tiller https://gcr.io/kubernetes-helm/tiller 3 [OK] timotto/rpi-tiller k8s.io/tiller for Raspberry Pi 1 itinerisltd/tiller 1 rancher/tiller 1 luxas/tiller 1 ibmcom/tiller Docker Image for IBM Cloud private-CE (Com... 1 ansibleplaybookbundle/tiller-apb An APB that deploys tiller for use with helm. 0 [OK] pcanham/tiller tiller image for Raspberry Pi for testing ... 0 kubeapps/tiller-proxy 0 appscode/tiller 0 jmgao1983/tiller from gcr.io/kubernetes-helm/tiller 0 [OK] anjia0532/tiller 0 4admin2root/tiller gcr.io/kubernetes-helm/tiller 0 [OK] ibmcom/tiller-ppc64le Docker Image for IBM Cloud Private-CE (Com... 0 szgrgo/helm-with-tiller Use helm and tiller together 0 [OK] 关注第一行:Mirror of https://gcr.io/kubernetes-helm/t... 因为gcr.io库的封锁,用这个镜像。
4、编辑安装的yaml:
cat tiller.yaml --- apiVersion: v1 kind: ServiceAccount metadata: name: tiller namespace: kube-system --- apiVersion: rbac.authorization.k8s.io/v1beta1 kind: ClusterRoleBinding metadata: name: tiller roleRef: apiGroup: rbac.authorization.k8s.io kind: ClusterRole name: cluster-admin subjects: - kind: ServiceAccount name: tiller namespace: kube-system [root@compass-user-hd-master3]:~#
5、执行命令:
kubectl apply -f tiller.yaml
6、再次验证:
[apps@mvxl1484 k8s]$ helm version Client: &version.Version{SemVer:"v2.11.0", GitCommit:"2e55dbe1fdb5fdb96b75ff144a339489417b146b", GitTreeState:"clean"} Error: could not find a ready tiller pod
7、代表tiller的pod已经存在,但是没有运行起来。执行命令:
[apps@mvxl1484 k8s]$ kubectl get pod --all-namespaces NAMESPACE NAME READY STATUS RESTARTS AGE 3d kube-system kubernetes-dashboard-58f5cb49c-zf7cn 1/1 Running 0 2d kube-system tiller-deploy-9bdb7c6bc-28rv6 0/1 ImagePullBackOff 0 42s
8、查看错误描述:
[apps@mvxl1484 k8s]$ kubectl describe pod tiller-deploy-9bdb7c6bc-28rv6 -n kube-system Name: tiller-deploy-9bdb7c6bc-28rv6 Namespace: kube-system Node: mvxl2655/10.16.91.120 Start Time: Thu, 22 Nov 2018 18:00:01 +0800 Labels: app=helm name=tiller pod-template-hash=568637267 Annotations: <none> Status: Pending IP: 10.16.3.18 Controlled By: ReplicaSet/tiller-deploy-9bdb7c6bc Containers: tiller: Container ID: Image: gcr.io/kubernetes-helm/tiller:v2.11.0 Image ID: Ports: 44134/TCP, 44135/TCP State: Waiting Reason: ImagePullBackOff Ready: False Restart Count: 0 Liveness: http-get http://:44135/liveness delay=1s timeout=1s period=10s #success=1 #failure=3 Readiness: http-get http://:44135/readiness delay=1s timeout=1s period=10s #success=1 #failure=3 Environment: TILLER_NAMESPACE: kube-system TILLER_HISTORY_MAX: 0 Mounts: /var/run/secrets/kubernetes.io/serviceaccount from tiller-token-ls9t2 (ro) Conditions: Type Status Initialized True Ready False PodScheduled True Volumes: tiller-token-ls9t2: Type: Secret (a volume populated by a Secret) SecretName: tiller-token-ls9t2 Optional: false QoS Class: BestEffort Node-Selectors: <none> Tolerations: node.kubernetes.io/not-ready:NoExecute for 300s node.kubernetes.io/unreachable:NoExecute for 300s Events: Type Reason Age From Message ---- ------ ---- ---- ------- Normal Scheduled 1m default-scheduler Successfully assigned tiller-deploy-9bdb7c6bc-28rv6 to mvxl2655 Normal SuccessfulMountVolume 1m kubelet, mvxl2655 MountVolume.SetUp succeeded for volume "tiller-token-ls9t2" Normal Pulling 1m (x2 over 1m) kubelet, mvxl2655 pulling image "gcr.io/kubernetes-helm/tiller:v2.11.0" Warning Failed 55s (x2 over 1m) kubelet, mvxl2655 Failed to pull image "gcr.io/kubernetes-helm/tiller:v2.11.0": rpc error: code = Unknown desc = Error response from daemon: Get https://gcr.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers) Warning Failed 55s (x2 over 1m) kubelet, mvxl2655 Error: ErrImagePull Warning Failed 50s (x5 over 1m) kubelet, mvxl2655 Error: ImagePullBackOff Normal SandboxChanged 49s (x7 over 1m) kubelet, mvxl2655 Pod sandbox changed, it will be killed and re-created.

9、为此要使用之前搜索到的镜像,编辑deploy,更改镜像地址:
[apps@mvxl1484 k8s]$ kubectl edit deploy tiller-deploy -n kube-system apiVersion: extensions/v1beta1 kind: Deployment metadata: annotations: deployment.kubernetes.io/revision: "2" creationTimestamp: 2018-11-22T10:00:00Z generation: 2 labels: app: helm name: tiller name: tiller-deploy namespace: kube-system resourceVersion: "398202" selfLink: /apis/extensions/v1beta1/namespaces/kube-system/deployments/tiller-deploy uid: 5fd7370d-ee3d-11e8-a632-0050568a39f2 spec: replicas: 1 selector: matchLabels: app: helm name: tiller strategy: rollingUpdate: maxSurge: 1 maxUnavailable: 1 type: RollingUpdate template: metadata: creationTimestamp: null labels: app: helm name: tiller spec: automountServiceAccountToken: true containers: - env: - name: TILLER_NAMESPACE value: kube-system - name: TILLER_HISTORY_MAX value: "0" image: sapcc/tiller:v2.11.0 imagePullPolicy: IfNotPresent 将 image gcr.io/kubernetes-helm/tiller:v2.11.0 替换成 image: sapcc/tiller:v2.11.0
10:、保存后,kubernetes会自动生效,再次查看pod,已经处于running状态了。
[apps@mvxl1484 k8s]$ kubectl get pod -n kube-system tiller-deploy-6b84d85487-4h272 1/1 Running 0 45s
11、验证helm
[apps@mvxl1484 k8s]$ helm version Client: &version.Version{SemVer:"v2.11.0", GitCommit:"2e55dbe1fdb5fdb96b75ff144a339489417b146b", GitTreeState:"clean"} Server: &version.Version{SemVer:"v2.11.0", GitCommit:"2e55dbe1fdb5fdb96b75ff144a339489417b146b
[root@k8s-master hello-svc]# helm version Client: &version.Version{SemVer:"v2.8.1", GitCommit:"6af75a8fd72e2aa18a2b278cfe5c7a1c5feca7f2", GitTreeState:"clean"} E0224 14:13:16.077226 7416 portforward.go:331] an error occurred forwarding 37271 -> 44134: error forwarding port 44134 to pod 76a7312e49220a229e443546a4b32d3e0406f09fd9b3646b3d30f6833e121375, uid : unable to do port forwarding: socat not found. Error: cannot connect to Tiller
解决办法在k8s 所有node节点上安装socat
yum install socat -y
