在浏览器中访问<http://172.20.0.113:8001/api/v1/namespaces/conduit/services/web:http/proxy/servicemesh>将看到如下页面：

## Conduit inject
|
||||
|
||||
Conduit注入的时候需要用到如下两个镜像：
|
||||
|
||||
- gcr.io/runconduit/proxy:v0.1.0
|
||||
- gcr.io/runconduit/proxy-init:v0.1.0
|
||||
|
||||
我将其备份到了DockerHub：
|
||||
|
||||
- jimmysong/runconduit-proxy:v0.1.0
|
||||
- jimmysong/runconduit-proxy-init:v0.1.0
|
||||
|
||||
查看conduit向yaml文件中注入了哪些配置，我们使用my-nginx.yaml为例：
|
||||
|
||||
```bash
|
||||
conduit inject --init-image sz-pg-oam-docker-hub-001.tendcloud.com/library/runconduit-proxy-init --proxy-image sz-pg-oam-docker-hub-001.tendcloud.com/library/runconduit-proxy my-nginx.yaml|kubectl apply -f -
|
||||
```
|
||||
|
||||
**注意：**只需要指定镜像名称即可，tag与使用的conduit server版本相同，会自动注入。
|
||||
|
||||
my-nginx.yaml的内容如下：
|
||||
|
||||
```yaml
|
||||
apiVersion: extensions/v1beta1
|
||||

|
||||

## 部署示例应用
|
||||
|
||||
使用下面的命令部署官方提供的示例应用：
|
||||
|
||||
```bash
|
||||
curl https://raw.githubusercontent.com/rootsongjc/kubernetes-handbook/master/manifests/conduit/emojivoto.yml | conduit inject --init-image sz-pg-oam-docker-hub-001.tendcloud.com/library/runconduit-proxy-init --proxy-image sz-pg-oam-docker-hub-001.tendcloud.com/library/runconduit-proxy - --skip-inbound-ports=80 | kubectl apply -f -
|
||||
```
|
||||
|
||||
**注意：**其中使用的镜像地址已经改为我的私有镜像仓库地址，大家使用时请注意修改。
