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 ")
