使用Shell腳本批量啟停Docker服務(wù)
發(fā)布日期：2022-02-22 13:37 | 文章來源：腳本之家
最近日常測試中經(jīng)常需要手動啟動或停止docker，于是決定寫一個(gè)Shell腳本來代替人工操作，另外該腳本，也可以通過Python腳本實(shí)行遠(yuǎn)程調(diào)用，詳細(xì)如下所示：
目前該腳本是將Container ID寫死在腳本中，當(dāng)然也可以通過傳參給腳本來進(jìn)行控制，大家可以改造一下。
啟動docker
啟動腳本詳細(xì)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 ${containerID}
fi
fi
done
done
停止docker
停止腳本詳細(xì)如下所示：
#!/bin/bash
containerIDs="589bda1309cd ad3e4d7fc407 a228730a915f ad3e4d7fc4099"
statusLived="live"
statusdead="Dead"
notExistContainer="None"
retryCount=3
function GetContainerStatus(){
containerExist=$(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調(diào)用腳本
Python示例腳本如下所示：
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 ")
總結(jié)
