服务器

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：

创新互联是一家集网站建设,卧龙企业网站建设,卧龙品牌网站建设,网站定制,卧龙网站建设报价,网络营销,网络优化,卧龙网站推广为一体的创新建站企业，帮助传统企业提升企业形象加强企业竞争力。可充分满足这一群体相比中小企业更为丰富、高端、多元的互联网需求。同时我们时刻保持专业、时尚、前沿，时刻以成就客户成长自我，坚持不断学习、思考、沉淀、净化自己，让我们为更多的企业打造出实用型网站。

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 )
