最好的方法是使用容器编排器/调度器,而不是手动执行类似的操作。例如,可以使用kubernetes cron jobs。

https://kubernetes.io/docs/tasks/job/automated-tasks-with-cron-jobs/

bt=[]
print("Enter the number of process: ")
n=int(input())
print("Enter the burst time of the processes: \n")
bt=list(map(int, raw_input().split()))

wt=[]
avgwt=0
tat=[]
avgtat=0

wt.insert(0,0)
tat.insert(0,bt[0])

for i in range(1,len(bt)):
   wt.insert(i,wt[i-1]+bt[i-1])
   tat.insert(i,wt[i]+bt[i])
   avgwt+=wt[i]
   avgtat+=tat[i]

avgwt=float(avgwt)/n
avgtat=float(avgtat)/n
print("\n")
print("Process\t  Burst Time\t  Waiting Time\t  Turn Around Time")

for i in range(0,n):
   print(str(i)+"\t\t"+str(bt[i])+"\t\t"+str(wt[i])+"\t\t"+str(tat[i]))
   print("\n")

print("Average Waiting time is: "+str(avgwt))
print("Average Turn Arount Time is: "+str(avgtat))

运行:

也许你需要修复你的dockerfile,并注意docker指令的顺序和一些最佳实践。

FROM openjdk:11-jre-slim
WORKDIR /dist
COPY dist/* .
EXPOSE 9000 9443

CMD ["/dist/bin/start","-Dhttps.port=9443"]

首先进行本地测试,通过执行到容器中并执行 ls

• 您不需要在Docker容器中运行SystemCtl
• 只是 docker restart <container name> 将执行此操作(如果要重新启动nginx)
• 你甚至不需要使用docker compose来运行nginx
• 你可以跑了 docker run --name nginx -v /opt/nginx:/usr/share/nginx/html -p 8080:80 docker.io/nginx

现在卷曲 http://<you machine ip>:8080 应该工作

为了检查目的,您可以使用input()方法,然后相应地进行决定。

列表理解版本:

sublist = [ i for i in the_list if i > n ]

生成器表达式:(如果列表太大)

sublist = ( i for i in the_list if i > n )

此设置在 /etc/docker/daemon.json 为我的用例工作:

{
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "1g"
  }
}
