我有一个像这样的豆荚列表：
❯ kubectl get pods -l app=test-pod (base)
NAME READY STATUS RESTARTS AGE
test-deployment-674667c867-jhvg4 1/1 Running 0 14m
test-deployment-674667c867-ssx6h 1/1 Running 0 14m
test-deployment-674667c867-t4crn 1/1 Running 0 14m
我有服务
kubectl get services (base)
NAMESPACE NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
default test-service ClusterIP 10.100.4.138 <none> 4000/TCP 15m
我执行一个 dns 查询：
❯ kubectl exec -ti test-deployment-674667c867-jhvg4 -- /bin/bash (base)
root@test-deployment-674667c867-jhvg4:/# busybox nslookup test-service
Server: 10.100.0.10
Address: 10.100.0.10:53
Name: test-service.default.svc.cluster.local
Address: 10.100.4.138
我的配置：
apiVersion: apps/v1
kind: Deployment
metadata:
name: test-deployment
spec:
replicas: 3
selector:
matchLabels:
app: test-pod
template:
metadata:
labels:
app: test-pod
spec:
containers:
- name: python-http-server
image: python:2.7
command: ["/bin/bash"]
args: ["-c", "echo \" Hello from $(hostname)\" > index.html; python -m SimpleHTTPServer 80"]
ports:
- name: http
containerPort: 80
kind: Service
apiVersion: v1
metadata:
name: test-service
spec:
selector:
app: test-pod
ports:
- protocol: TCP
port: 4000
targetPort: http
我怎样才能通过 dns 查询获取所有 pod 的 IP 地址列表？
理想情况下，我想执行nslookup一个名称并获取列表中所有 pod 的 ips 的列表。
