使用Shell脚本批量启停Docker服务
作者：Surpassme
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，下面小编把我实现过程分享到脚本之家平台，需要的朋友参考下
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
