Directory start docker stop dockerPython call script
Recently, it is often necessary to start or stop docker manually in daily tests, so it is decided to write an Shell script instead of manual operation. In addition, this script can also be called remotely through Python script, as follows:
At present, the script is Container ID written dead in the script, of course, can also pass the reference to the script for control, we can transform 1.
Start docker
The startup script is detailed as follows:
#!/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 ${containerID}
fi
fi
done
done
Stop docker
The stop script details are as follows:
#!/bin/bash
containerIDs="589bda1309cd ad3e4d7fc407 a228730a915f ad3e4d7fc4099"
statusLived="live"
statusdead="Dead"
notExistContainer="None"
retryCount=3
function GetContainerStatus(){
containerExist=$(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 call script
The Python sample script looks like this:
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 ")
Summarize
The above is the site to introduce the use of Shell script batch start-stop Docker service, I hope to help you!
