Shell脚本批量启停Docker

目录

  • 启动docker
  • 停止docker
  • Python调用脚本

    最近日常测试中经常需要手动启动或停止docker,于是决定写一个Shell脚本来代替人工操作,另外该脚本,也可以通过Python脚本实行远程调用,详细如下所示:

目前该脚本是将Container ID写死在脚本中,当然也可以通过传参给脚本来进行控制,大家可以改造一下。

启动docker

启动脚本详细如下所示:

#!/bin/bash

containerIDs="ad3e4d7fc407 a228730a915f ad3e4d7fc4099"
statusLived="live"
statusdead="Dead"
notExistContainer="None"
retryCount=3

function GetContainerStatus(){
   containerExist=$(sudo docker ps -a | grep -i $1 | wc -l )   
   if [ ${containerExist} -gt 0 ]
     then
       pid=$(sudo docker stats --format "{{.PIDs}}" --no-stream $1 )
       if [ "${pid}" != "0" ]
         then   
           echo "${statusLived}"
       else
           echo "${statusdead}"
       fi
    else
      echo "${notExistContainer}" 
   fi
}

function StartContainer(){
  sudo docker restart $1
}

for containerID in ${containerIDs}
 do
   for((i=1;i<=${retryCount};i++))
   do
    status=$(GetContainerStatus ${containerID} )
    echo "Container ${containerID} status is ${status}"

    if [ "${status}" == ${statusLived}  ]
      then
        echo "Container ${containerID} already running"
        break
    fi

    if [ "${status}" == ${notExistContainer}  ]
      then
        echo "Container ${containerID} not existed"
        break
    fi

    if [ "${status}" == ${statusdead}  ]
      then
        echo "Container ${containerID} stopped ,start container"
        StartContainer ${containerID}
        verifyStatus=$(GetContainerStatus ${containerID} )
        if [ "${verifyStatus}" == ${statusLived}  ]
           then
             echo "start container ${containerID} success "
             break
        else
           echo "${i} retry start container"
           StartContainer ${containerID}
        fi
    fi
  done
done

停止docker

停止脚本详细如下所示:

#!/bin/bash

containerIDs="589bda1309cd ad3e4d7fc407 a228730a915f ad3e4d7fc4099"
statusLived="live"
statusdead="Dead"
notExistContainer="None"
retryCount=3

function GetContainerStatus(){
   containerExist=$(sudo docker ps -a | grep -i $1 | wc -l )   
   if [ ${containerExist} -gt 0 ]
     then
       pid=$(sudo docker stats --format "{{.PIDs}}" --no-stream $1 )
       if [ "${pid}" != "0" ]
         then   
           echo "${statusLived}"
       else
           echo "${statusdead}"
       fi
    else
      echo "${notExistContainer}" 
   fi
}

function StopContainer(){
  sudo docker stop $1
}

for containerID in ${containerIDs}
 do
  for ((i=1;i<=${retryCount};i++))
    do
     status=$(GetContainerStatus ${containerID} )
     echo "Container ${containerID} status is ${status}"

     if [ "${status}" == ${statusdead}  ]
      then
        echo "Container ${containerID} already stopped"
        break
     fi

     if [ "${status}" == ${notExistContainer}  ]
       then
        echo "Container ${containerID} not existed"
        break
     fi

     if [ "${status}" == ${statusLived}  ]
       then
         echo "Container ${containerID} is lived ,stop container"
         StopContainer ${containerID}
         verifyStatus=$(GetContainerStatus ${containerID} )
         if [ "${verifyStatus}" == ${statusdead}  ]
           then
              echo "stop container ${containerID} success "
              break
         else
            echo "${i} retry stop container"
            StopContainer ${containerID}
         fi
      fi
   done
done

Python调用脚本

Python示例脚本如下所示:

import paramiko

def StartContainer(svr,port,user,pwd):
    client = paramiko.SSHClient()
    client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    client.connect(svr,port=port, username=user, password=pwd,timeout=5)
    client.exec_command("cd /home/TestCode/ && bash startContainer.sh")

def StopContainer(svr,port,user,pwd):
    client = paramiko.SSHClient()
    client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    client.connect(svr, port=port, username=user, password=pwd, timeout=5)
    client.exec_command("cd /home/TestCode/ && bash stopContainer.sh ")
