Shell腳本批量啟停Docker

目錄

• 啟動docker
• 停止docker
• Python調用腳本

    最近日常測試中經常需要手動啟動或停止docker，於是決定寫一個Shell腳本來代替人工操作，另外該腳本，也可以通過Python腳本實行遠程調用，詳細如下所示：

目前該腳本是將Container ID寫死在腳本中，當然也可以通過傳參給腳本來進行控制，大家可以改造一下。

啟動docker

啟動腳本詳細如下所示：

#!/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

停止腳本詳細如下所示：

#!/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調用腳本

Python示例腳本如下所示：

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 ")
