## 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
kind: Deployment
metadata:
name: my-nginx
spec:
replicas: 2
template:
metadata:
labels:
run: my-nginx
spec:
containers:
- name: my-nginx
image: sz-pg-oam-docker-hub-001.tendcloud.com/library/nginx:1.9

apiVersion: v1

metadata:
name: my-nginx
labels:
app: my-nginx
spec:
ports:
- port: 80
protocol: TCP
name: http

```
Conduit自动注入后生成的新的yaml文件内容如下：
```yaml

## 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。
