Issues creating database cluster in Singapore

Gabriel · April 18, 2021, 5:25pm

I’m trying to create a database cluster following the docs

Ran fly postgres create

Selected sin as the location.

After taking 11 minutes, the process stopped running. I checked it with fly postgres list and noticed it’s “pending”. Trying fly restart divine-wind-7241 causes it to go into “suspended” mode.

Here’s the logs if it helps:

$ flyctl --app divine-wind-7241 logs

We just deployed a fix for this. If you delete that app and create a new one you should be good to go.

Gabriel · April 18, 2021, 5:33pm

Trying that now! Thanks Michael!!

Any idea what went wrong? Wondering if there’s any way I could debug issues with setting up PG clusters in future.

michael · April 18, 2021, 5:35pm

This was a bug on our end that wasn’t configuring consul correctly, not much you could do.

Gabriel · April 18, 2021, 5:38pm

Oh no. Gotcha, thanks for resolving this so quickly! You’re awesome!

Just got it deployed in 2m55s.

Can’t wait to get this connected with my other fly apps!

2 quick questions though:

can I use the same cluster for multiple, non-related fly apps?
when scaling the PG cluster, does it replicate data over? (any downtime when doing so?)

michael · April 18, 2021, 5:49pm

Glad it worked!

Yes you can share one or more databases in the cluster across multiple fly apps

Yes, everything replicates to secondaries. Unless the primary fails over (restart from scaling memory/cpu, failure, etc) you won’t have downtime.
