迈向istio-0 安装
istio-安装
[TOC]
下载istio的release
curl -L https://git.io/getLatestIstio | sh -
cd istio-1.0.2
#设置环境变量,以便后面可以执行istioctl命令
export PATH=$PWD/bin:$PATH
下载helm
wget https://storage.googleapis.com/kubernetes-helm/helm-v2.11.0-linux-amd64.tar.gz
tar zxvf helm-v2.11.0-linux-amd64.tar.gz
export PATH=$PWD/linux-amd64/:$PATH
开始安装
$ kubectl apply -f install/kubernetes/helm/istio/templates/crds.yaml
有两种方式均可以安装istio,这里我们使用helm生成yaml的方式(因为helm的方式安装的istio,不用再去自己下载gcr.io中的镜像)
因为我本人使用的是本地电脑,所以我需要对istio安装的参数进行一定的修改,具体修改如下:
复制一个新的istio-1.0.2/install/kubernetes/helm/istio/values.yaml文件出来
修改gateways为NodePort
gateways: enabled: true #省略n多节点 type: ClusterIP #修改为NodePort启用grafana,将grafana节点下的enabled修改为true
grafana: enabled: false #修改为true #省略... service: annotations: {} name: http type: ClusterIP #修改为NodePort externalPort: 3000 internalPort: 3000启用prometheus
prometheus: enabled: true replicaCount: 1 hub: docker.io/prom tag: v2.3.1 service: annotations: {} nodePort: enabled: false #修改为true port: 32090启用servicegraph
servicegraph: enabled: false #修改为true replicaCount: 1 image: servicegraph service: annotations: {} name: http type: ClusterIP #修改为NodePort externalPort: 8088 internalPort: 8088启用jaeger
tracing: enabled: false #修改为true provider: jaeger #省略... service: annotations: {} name: http type: ClusterIP #修改为NodePort externalPort: 9411 internalPort: 9411(可选) 修改追踪
pilot: enabled: true replicaCount: 1 autoscaleMin: 1 autoscaleMax: 5 image: pilot sidecar: true traceSampling: 1.0 #修改为100.0,默认采样1%,但是在测试阶段 可以采取大量采样模式(可选) 启用kiali
kiali: enabled: false #修改为true replicaCount: 1 hub: docker.io/kiali tag: v0.9 ingress:
修改完成后保存文件
$ helm template install/kubernetes/helm/istio --name istio --namespace istio-system -f 修改后的value路径.yaml > ./istio.yaml
$ kubectl create namespace istio-system
$ kubectl apply -f ./istio.yaml
在安装istio的过程中某一些镜像下载的时间过长,请耐心等待.
