Shell脚本批量启停Docker（shell自动重启脚本）

Shell脚本批量启停Docker（shell自动重启脚本）

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 ")
