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：

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 ")
