Ch15 建立 iperf 測試環境
步驟
-
在此使用 Docker Hub networkstatic/iperf3 1 預先安裝好
iperf32 命令的 image。 以下建置 iperf server-side：$ cat ./iperf3-demo.yaml
apiVersion: v1
kind: Namespace
metadata:
name: iperf3
---
apiVersion: v1
kind: Pod
metadata:
name: iperf3-client
namespace: iperf3
spec:
nodeSelector:
kubernetes.io/hostname: ip-192-168-34-221.eu-west-1.compute.internal
containers:
- name: iperf3
image: networkstatic/iperf3
command:
- sleep
- infinity
imagePullPolicy: IfNotPresent
restartPolicy: Always
---
apiVersion: v1
kind: Pod
metadata:
name: iperf3-server
namespace: iperf3
spec:
nodeSelector:
kubernetes.io/hostname: ip-192-168-34-221.eu-west-1.compute.internal
containers:
- name: iperf3
image: networkstatic/iperf3
command:
- sleep
- infinity
imagePullPolicy: IfNotPresent
restartPolicy: Always -
使用
networkstatic/iperf3image 部署 server-side 及 client-side。$ kubectl apply -f ./iperf3-demo.yaml
namespace/iperf3 created
pod/iperf3-client created
pod/iperf3-server created -
檢視 pod 啟用於相同的節點上，instance id：
i-0ea90c13bca800dc5。$ kubectl -n iperf3 get po -o wide
NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES
iperf3-client 1/1 Running 0 5m27s 192.168.45.50 ip-192-168-34-221.eu-west-1.compute.internal <none> <none>
iperf3-server 1/1 Running 0 5m27s 192.168.60.100 ip-192-168-34-221.eu-west-1.compute.internal <none> <none>
$ kubectl get no ip-192-168-34-221.eu-west-1.compute.internal -o jsonpath='{.spec.providerID}'
aws:///eu-west-1d/i-0ea90c13bca800dc5 -
使用 iperf3 命令作為 server side。
$ kubectl -n iperf3 exec -it iperf3-server -- iperf3 -s -f K
-----------------------------------------------------------
Server listening on 5201
----------------------------------------------------------- -
使用 iperf3 command 作為 client side 並指定 server IP
192.168.60.100。$ kubectl -n iperf3 exec -it iperf3-client -- iperf3 -c 192.168.60.100 -f K
