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 ")

The above is the site to introduce the use of Shell script batch start-stop Docker service, I hope to help you!
