Use Shell scripts to batch start and stop Docker services

Use Shell scripts to batch start and stop Docker services

Recently, I often need to manually start or stop docker in daily testing, so I decided to write a Shell script to replace manual operation. In addition, the script can also be called remotely through a Python script, as shown below:

Currently, the script hard-codes the Container ID in the script. Of course, you can also control it by passing parameters to the script. You can modify it.

Start Docker

The startup script is 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 ${containerID} did not exist"
  break
 fi
 if [ "${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 is 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 ${containerID} did not exist"
  break
  fi
  if [ "${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 calling script

The Python sample script is as follows:

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 ")
