sudo vim /etc/kubernetes/manifests/kube-apiserver.yaml
- --service-account-issuer=api
- --service-account-api-audiences=api,vault,factors
- --feature-gates=RemoveSelfLink=false
- --service-account-signing-key-file=/etc/kubernetes/pki/sa.key
2、创建 namespace
kubectl create namespace istio-system
3
、添加 helm 源
helm repo add istio https://istio-release.storage.googleapis.com/charts
helm repo list
helm repo update
4、 安装 Istio Base Chart
helm install istio-base istio/base -n istio-system --set defaultRevision=default
5、查看
helm ls -n istio-system
6
、安装 Istio Discovery Chart，它用于部署 istiod 服务
helm install istiod istio/istiod -n istio-system
7
、安装 gateway
kubectl create namespace istio-ingress
helm install istio-ingress istio/gateway -n istio-ingress
8、验证
创建 nginx
-rw-rw-r-- 1 keda keda 709 12月 10 15:16 nginx-VirtualService.yaml
keda@citc-OpenStack-Nova:~/istio$ cat nginx-deployment.yaml
apiVersion: apps/v1
