這篇文章主要介紹了Helm管理工具怎么用，具有一定借鑒價(jià)值，感興趣的朋友可以參考下，希望大家閱讀完這篇文章之后大有收獲，下面讓小編帶著大家一起了解一下。
成都創(chuàng)新互聯(lián)響應(yīng)式網(wǎng)站特點(diǎn)就是不管在電腦、平板還是手機(jī)上，H5建站都會(huì)根據(jù)屏幕尺寸自動(dòng)調(diào)節(jié)大小、圖片分辨率，并且融入一定的動(dòng)畫(huà)特效，讓網(wǎng)站看起來(lái)非常的美觀大方。從網(wǎng)站需求對(duì)接到網(wǎng)站制作設(shè)計(jì)、從代碼編寫(xiě)到項(xiàng)目上線運(yùn)維，技術(shù)人員全程跟蹤，快速響應(yīng)
一 Helm 簡(jiǎn)介
Helm:
chart: 一個(gè)helm程序包
Repository: Charts倉(cāng)庫(kù)，https/http服務(wù)器
Release：特定的chart部署于目標(biāo)集群上的一個(gè)實(shí)例
Chart -> Config -> Release
helm:客戶(hù)端。管理本地Chart倉(cāng)庫(kù)，管理Chart，與Tiller服務(wù)器交互，發(fā)送Chart，實(shí)例安裝，查詢(xún)，卸載等操作
Tiller： 服務(wù)端，接收helm發(fā)來(lái)的Chart與Config,合并生成Release
二 部署Helm
1 下載helm
wget https://storage.googleapis.com/kubernetes-helm/helm-v2.13.1-linux-amd64.tar.gz
2 解壓
tar xf helm-v2.13.1-linux-amd64.tar.gz
3 安裝helm
重慶分公司
重慶分公司
cd linux-amd64/
mv helm /usr/bin/
# helm version
Client: &version.Version{SemVer:"v2.13.1", GitCommit:"618447cbf203d147601b4b9bd7f8c37a5d39fbb4", GitTreeState:"clean"}
Error: could not find tiller4 安裝 tiller
部署tiller對(duì)于開(kāi)啟rbac認(rèn)真的集群需要進(jìn)行rbac授權(quán)并且綁定在集群級(jí)別的clusterrolebinding
# cat tiller-rbac.yaml apiVersion: v1 kind: ServiceAccount metadata: name: tiller namespace: kube-system --- apiVersion: rbac.authorization.k8s.io/v1 kind: ClusterRoleBinding metadata: name: tiller roleRef: apiGroup: rbac.authorization.k8s.io kind: ClusterRole name: cluster-admin subjects: - kind: ServiceAccount name: tiller namespace: kube-system kubectl apply -f tiller-rbac.yaml 如果想要部署在特定的名稱(chēng)該空間使用請(qǐng)參考官網(wǎng) https://github.com/helm/helm/blob/master/docs/rbac.md 查看tiller # kubectl get serviceaccount -n kube-system | grep tiller tiller 1 4m25s
5 初始化tiller
helm init --service-account tiller --history-max 200 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! 可以預(yù)先設(shè)置下載proxy export HTTPS_PROXY='http://www.ik8s.io:10080' 如果提示失敗并且是連接https://ip:6443超時(shí)可以通過(guò)設(shè)置環(huán)境變量 export NO_PROXY='節(jié)點(diǎn)ip/16,回環(huán)地址/16' 再次安裝
