这个配置看着也是对的，你的电脑能够远程么，我看下，可以把登录方式发到 kubesphere@yunify.com

for-mat · 2019年10月17日

没法远程。。

我到这一步，都是正常的，这里也显示了istio-proxy，创建后是就绪的，但是查看pod状态，就没有这个istio-proxy了

for-mat · 2019年10月17日

不行我再手动部署istio官方的实例试试

Jeff · 2019年10月17日

for-mat 执行下这个命令看下，ns是否打上label了

kubectl get ns test-namespace -o yaml

Jeff · 2019年10月17日

for-mat 把这个label去掉 istio-injection: enabled，重新部署应用试下

for-mat · 2019年10月17日

Jeff 去掉试了还是不行，另外我照着istio官方文档操作了下
也没有注入sidecar，我检查了apiserver启动项
–admission-control=NamespaceLifecycle,LimitRanger,ServiceAccount,DefaultStorageClass,ResourceQuota,NodeRestriction \
也开启了自动sidecar注入，但就是不生效。
我的k8s是1.13.10
奇了怪了，我再手动试试。。。

for-mat · 2019年10月17日

Jeff 大佬，istio-sidecar-injector的configmap没有values
[root@master100 bin]# ./istioctl kube-inject -f ../samples/sleep/sleep.yaml | kubectl apply -f -
Error: missing configuration map key “values” in “istio-sidecar-injector”
error: no objects passed to apply

Jeff · 2019年10月17日

for-mat 你的环境是默认安装的么，还是在已有的k8s上安装的？最好能有个环境我看下

for-mat · 2019年10月17日

我滴妈呀，终于解决了
1、我是已有k8s集群上搭的kubesphere
kube-apiserver的启动参数中，要有–admission-control=MutatingAdmissionWebhook，开启自动注入
2、MutatingWebhookConfiguration配置有问题
kubectl -n istio-system edit MutatingWebhookConfiguration istio-sidecar-injector
下面两个参数改成In和enabled
operator: In
values:
- enabled
3、给用到的namespace打标签
kubectl label namespace test-namespace istio-injection=enabled
4、感谢大佬帮忙

for-mat · 2019年10月17日

不知道是不是默认都会这样，我装了两次是都不行。也可能是因为我自己搭的集群

Jeff · 2019年10月17日

安装bookinfo示例总是没有注入sidecar
