Shell脚本批量启停Docker

目录

• 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：

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 ")
