check-container-status

Simply bash script to check connectivity of expected $docker_network for a defined number of containers (last ip of subnet = $last_ip) and send $email if the numbers of containers up are not the expected (declare as $expected_containers).

Usage

• To use that script you have to change variables on the script (at the start).
  • $docker_network (network to analyze).
  • $firts_ip (firts ip of the network).
  • $email (email to send alerts).
  • $expected_containers (number of containers expected on $docker_network).
• For automate that task add script to crontab and do it with the frecuence that you want.
• Additionally you can remove echo msgs on script to cleaner output.
• By default alerts go to spam folder, just declare this alerts as no spam.
