No, there was no warning at all! I tweeted Oracle Cloud to point out the issue, and then I tweeted Larry Ellison himself. I doubt whether he will respond...

I've just been reading about Larry Ellison on Wikipedia; I don't think he's going to starve any time soon 😡

This was the email I received a few days ago...

Dear Customer,

This letter is to inform you that your Cloud Services described below were terminated on Monday, April 7, 2025 03:16 AM Coordinated Universal Time.

The termination stopped all running services and purged the data. All data was deleted and is non-recoverable.

For any further assistance, please contact Oracle Support.

Absolutely no warning, whatsoever 😡 As a piece of customer relations, it stinks to high heaven, and will ensure that I never have anything to do with Oracle again.

In any case it's all a bit immaterial because those scumbags at Oracle have just deleted the free tier account that I had foolishly and naively thought would continue indefinitely. @Owen Hilyard, do you know why Oracle would just delete my account with no warning or opportunity to extend it?

Does this mean that Lightbug has moved to a 0.1.17 version which is not compatible?

@a2svior It still has problems, occasionally, connecting to the web site, but I think this may be more to do with the fact that I'm using the free-tier service from Oracle (words that I thought I would never use in the same sentence 😉) rather than any software related issue.

Interesting! Looks like we have a Gemini 2.0 Flash vs Claude AI faceoff 😉 I agree about the redundent docker start command. Also, I've discovered that after running this script, it seems to take Oracle about a minute or so before it will star receiving web requests again. I like the addition of the --restart unless-stopped flag. I've just looked it up and it seems totally appropriate for my situation. Thanks for the heads up 🙏🏽

However, I think there is a slight problem. Okay, the docker ps -a shows that the instance has been running for 24 hours now! But I had to run docker start ca-web-container on two occasions now in order for me to be able to access the site at http://132.145.47.167:8080/.
