# 1. 在容器中获取 Pod 的IP
|
||
|
|
|
||
|
|
通过环境变量来实现，该环境变量直接引用 resource 的状态字段，示例如下：
|
||
|
|
|
||
|
|
```Yaml
|
||
|
|
apiVersion: v1
|
||
|
|
kind: ReplicationController
|
||
|
|
metadata:
|
||
|
|
name: world-v2
|
||
|
|
spec:
|
||
|
|
replicas: 3
|
||
|
|
selector:
|
||
|
|
app: world-v2
|
||
|
|
template:
|
||
|
|
metadata:
|
||
|
|
labels:
|
||
|
|
app: world-v2
|
||
|
|
spec:
|
||
|
|
containers:
|
||
|
|
- name: service
|
||
|
|
image: test
|
||
|
|
env:
|
||
|
|
- name: POD_IP
|
||
|
|
valueFrom:
|
||
|
|
fieldRef:
|
||
|
|
fieldPath: status.podIP
|
||
|
|
ports:
|
||
|
|
- name: service
|
||
|
|
containerPort: 777
|
||
|
|
```
|
||
|
|
|
||
|
|
容器中可以直接使用 `POD_IP` 环境变量获取容器的 IP。
