58、 Helm 及其它功能性组件 - Helm（1](tiller)

发布时间：2023-01-14 13:19:04编辑：雪饮阅读（）

Step1

创建目录

mkdir /usr/local/install-k8s/helm

拿到这个资源

https://storage.googleapis.com/kubernetes-helm/helm-v2.13.1-linux-amd64.tar.gz

放到目录/usr/local/install-k8s/helm中

这里再熟悉一个命令，就是回到上次工作目录

[root@k8s-master01 helm]# cd !$

然后咱们重新回到咱们的主线，接着是解压这个helm-v2.13.1-linux-amd64.tar.gz

[root@k8s-master01 helm]# tar -zxvf helm-v2.13.1-linux-amd64.tar.gz

linux-amd64/

linux-amd64/LICENSE

linux-amd64/tiller

linux-amd64/helm

linux-amd64/README.md

cp -a 保留原文件属性的前提下复制文件 

那么接下来我们将可执行文件放到对应目录

[root@k8s-master01 helm]# cp -a linux-amd64/helm /usr/local/bin/

赋权

[root@k8s-master01 helm]# chmod a+x /usr/local/bin/helm




 

Step2

各节点提前加载所需依赖的一个可能大多数情况下无法正常docker pull的镜像（该镜像如果你docker不出现网络问题能正常pull下来则无需了）

我这里该镜像来自于老师的资料

E:\10、Kubernetes - Helm 及其它功能性组件\鸿鹄论坛_10、Kubernetes - Helm 及其它功能性组件\2、资料

中的镜像文件.zip.001进行分卷解压后的完整路径为

E:\10、Kubernetes - Helm 及其它功能性组件\鸿鹄论坛_10、Kubernetes - Helm 及其它功能性组件\2、资料\镜像文件.zip\Images\helm\ helm-tiller.tar

文件

[root@k8s-node01 ~]# docker load -i helm-tiller.tar

3fc64803ca2d: Loading layer [==================================================>]  4.463MB/4.463MB

79395a173ae6: Loading layer [==================================================>]  6.006MB/6.006MB

c33cd2d4c63e: Loading layer [==================================================>]  37.16MB/37.16MB

d727bd750bf2: Loading layer [==================================================>]  36.89MB/36.89MB

Loaded image: gcr.io/kubernetes-helm/tiller:v2.13.1

然后重回master节点咱们创建yaml模板如：

[root@k8s-master01 helm]# cat rbac.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

然后创建ServiceAccount和ClusterRoleBinding

[root@k8s-master01 helm]# kubectl create -f rbac.yaml

serviceaccount/tiller created

clusterrolebinding.rbac.authorization.k8s.io/tiller created

 

然后初始化哈

[root@k8s-master01 helm]# helm init --service-account tiller --skip-refresh

Creating /root/.helm

Creating /root/.helm/repository

Creating /root/.helm/repository/cache

Creating /root/.helm/repository/local

Creating /root/.helm/plugins

Creating /root/.helm/starters

Creating /root/.helm/cache/archive

Creating /root/.helm/repository/repositories.yaml

Adding stable repo with URL: https://kubernetes-charts.storage.googleapis.com

Adding local repo with URL: http://127.0.0.1:8879/charts

$HELM_HOME has been configured at /root/.helm.

 

Tiller (the Helm server-side component) has been installed into your Kubernetes Cluster.

 

Please note: by default, Tiller is deployed with an insecure 'allow unauthenticated users' policy.

To prevent this, run `helm init` with the --tiller-tls-verify flag.

For more information on securing your installation see: https://docs.helm.sh/using_helm/#securing-your-helm-installation

Happy Helming!

这样就没有问题咯

[root@k8s-master01 helm]# kubectl get pod -n kube-system

tiller-deploy-58565b5464-64scg         1/1     Running   0          37s

Step3

Hai。。。然后咱们给master节点也上传刚才的那个helm-tiller.tar的镜像到master的这个目录

/usr/local/install-k8s/helm

[root@k8s-master01 helm]# ls

helm-tiller.tar  helm-v2.13.1-linux-amd64.tar.gz  linux-amd64  rbac.yaml

当然了，这一步骤就目前来看好像是非必。

因为这里老师好像只是为了整理到一个文件夹里面，看起来整齐点

然后查看下helm版本哈

[root@k8s-master01 helm]# helm version

Client: &version.Version{SemVer:"v2.13.1", GitCommit:"618447cbf203d147601b4b9bd7f8c37a5d39fbb4", GitTreeState:"clean"}

Server: &version.Version{SemVer:"v2.13.1", GitCommit:"618447cbf203d147601b4b9bd7f8c37a5d39fbb4", GitTreeState:"clean"}

这样就是没问题了哈
