使用Shell脚本批量启停Docker服务

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 ")

总结
