Stopping right after coming up

[sanealytics]

I'm using this image with 4Gb Google Cloud Run for a small experiment.
It comes up, but shuts down rightaway.

No obvious errors. Here are the only things that stand out to me:

I tried passing discovery.type=single-node and http.host=0.0.0.0 as environment variables, but still had the same outcome.

I'm not very familiar with elasticsearch.
Any suggestions on how to run this configuration?

Thanks
