CI-CD

Scripts to handle automated creation of test instances and the production environment

Setup:

Periodic Shutdown of Instances

Configure CRON with the following line (or similar). You can do this with crontab -e.

PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
0 0 * * * /bin/bash /home/pollbuddy/CI-CD/periodicShutdown.sh >> /var/log/cron/pollbuddy-periodicShutdown.log 2>&1
0 0 * * * /bin/bash /home/pollbuddy/CI-CD/periodicDelete.sh >> /var/log/cron.d/pollbuddy-periodicDelete.log 2>&1

Path is just what I had. It can likely be much more limited. You may want to use the output of the echo $PATH command so that it's specific to your system.

This will run the scripts periodicShutdown.sh and periodicDelete.sh every day at midnight and log output to /var/log/cron/pollbuddy-periodicShutdown.log and /var/log/cron/pollbuddy-periodicDelete.log, respectively.

Notes:

If you are running this yourself, add this line to your docker.service file to ensure there is enough Docker Network space for all the instances: --default-address-pool base=10.127.0.0/16,size=28

Alternatively, configure it in /etc/docker/daemon.js: (... indicates possible existing values. Do not include the ...'s)

{
    ...
    "default-address-pools":
        [
            {
                "base": "10.127.0.0/16",
                "size": 28
            }
        ]
    ...
}
