Instance Scheduler #18

Open robertmassaioli opened 2 years ago

Great AWS template! Saves me the effort of having to do this myself.

I have a feature idea: could you integrate an EC2 Scheduler into this such that we only run this EC2 instance at legitimate times that I would actually Play Factorio.

For example, I would only ever play Factorio from 5pm-9pm Weekdays and 7am-Midday on Weekends. If the EC2 instance automatically came up during those times it would prevent me from having to manually update the stack. Cheers!

Even just documentation for how to use something like https://aws.amazon.com/solutions/implementations/instance-scheduler/ in tandem with this would be useful.

Hi @robertmassaioli glad you like it.

You probably don't want that instance scheduler from AWS, last time I looked it was expensive to run and regardless, from memory it doesn't support auto scaling groups - it just turns on and off individual instances.

We don't need that much complexity. I should be able to have a look in a little bit (you can look if you like and submit a PR); you probably want to add a couple of AWS::AutoScaling::ScheduledAction resources to the CloudFormation template. One of these resources would let you set the auto scaling group to desired/min/max 1/1/1 at the start of the day which will start the server, and the other 0/0/0 at the end of the day. Note that the Recurrence property will be a cron in UTC time, not your local time.

If you submit a PR, just be sure to make the feature optional via params / update docs etc.
