I created a small python script that checks if all docker containers are running.
- Backup all container names into a file:
docker ps --format "{{.Names}}" > /root/containers.txt - Create a script that checks if all containers are running:
vim /root/check.py(Content see below) - Do stuff that might impact container uptime
- Run the script:
python3 /root/check.py - See if every container are still running
=> Offline-Containers are highlighted in red.
Script Content:
#!/usr/bin/python3
import subprocess
class bcolors:
HEADER = '\033[95m'
OKBLUE = '\033[94m'
OKCYAN = '\033[96m'
OKGREEN = '\033[92m'
WARNING = '\033[93m'
FAIL = '\033[91m'
ENDC = '\033[0m'
BOLD = '\033[1m'
UNDERLINE = '\033[4m'
f = open("/root/containers.txt", "r")
containers = f.read().splitlines()
docker_ps_output = str(subprocess.check_output('docker ps', shell=True))
for container in containers:
if docker_ps_output.find(container) != -1:
print(f"{bcolors.OKGREEN}Container found {container}{bcolors.ENDC}")
else:
print(f"{bcolors.FAIL}Container not found {container}{bcolors.ENDC}")
