App not updating nightly
Closed this issue · 4 comments
Our app isn't updating nightly like it should be.
We have a command run in the middle of the night to look for new SORNs. Yet, our worker isn't awake then. We need to define a worker process to be waiting to do do work.

We had been starting GoodJob (our worker) by hand. It gets stopped whenever there is a deploy though (I assume).
On Heroku, this would double the monthly bill. I don't know how Cloud.gov charges.
I started GoodJob by hand yesterday on production. It still didn't get any new SORNs last night.
we could use github actions to do a nightly redeploy and then just have it run find-sorns then
Ah, I see. Cloud.gov doesn't let us use their cron to run tasks. https://cloud.gov/docs/management/one-off-tasks/
Run periodic scheduled tasks
If you’d like to run a periodic scheduled task (similar to a cron job), you should find a cron-like library in the programming language that you’re working with, and implement the task using that library. You may run this as part of an existing application or as a separate application.
If you use continuous deployment, you can use a timer as an input to a task or pipeline that runs a Cloud Foundry Task. You can see a demonstration of this approach using the Travis CI/CD platform here. Note - this same approach can be easily adapted to other common CI/CD platforms like Jenkins, CircleCI and GitHub Actions.
We should remove the crontab and whenever gem that we were trying.
Laura had some ideas I wanted to write down so we don't forget:
- Use a Github Action to run
find_sornseverynight. - Schedule a repeating GoodJob to run
find_sornseverynight. Reading about this though, it can be a little fragile. Our job is simple enough though, that I still think it is a valid approach.
