创建pod后如何使Kubectl运行容器 [英] How to Make Kubectl run a container after pod is created

问题描述

目的是从命令行执行加特林性能测试.等效的docker命令是

Intention is to execute gatling perf tests from command line .Equivalent docker command is

docker run --rm  -w /opt/gatling-fundamentals/ 
tarunkumard/tarungatlingscript:v1.0 
./gradlew gatlingRun-simulations.RuntimeParameters -DUSERS=500 -DRAMP_DURATION=5 -DDURATION=30

现在要使用kubectl映射在Kubernetes中运行的docker上方，我创建了一个pod，其gradlewcommand.yaml文件位于下面

Now to map above docker run in Kubernetes using kubectl, I have created a pod for which gradlewcommand.yaml file is below

apiVersion: v1
kind: Pod
metadata:
name: gradlecommandfromcommandline
labels:
purpose: gradlecommandfromcommandline
spec:
containers:
- name: gradlecommandfromcommandline
image: tarunkumard/tarungatlingscript:v1.0
workingDir: /opt/gatling-fundamentals/
command: ["./gradlew"]
args: ["gatlingRun-simulations.RuntimeParameters", "-DUSERS=500", "- 
DRAMP_DURATION=5", "-DDURATION=30"]
restartPolicy: OnFailure

现在使用以下命令创建窗格:-

Now pod is created using below command:-

kubectl apply -f gradlewcommand.yaml 

现在是我的实际要求或问题，我该如何运行或触发kubectl run命令以便在上面创建的容器中运行容器? ，请注意，您的广告连播名称是来自命令行的gradlecommand

Now comes my actual requirement or question that how do i run or trigger kubectl run command so as to run container inside the above pod created? ,mind you pod name is gradlecommandfromcommandline

推荐答案

以下是解决该问题的命令:

Here is the command which solves the problem:

 kubectl exec gradlecommandfromcommandline -- \
   ./gradlew gatlingRun-simulations.RuntimeParameters \
   -DUSERS=500 -DRAMP_DURATION=5 -DDURATION=30
