It's connecting with SSL, exclusively, using the standard suite of Mozilla Web PKI CAs

Struggling to set up a Tunnel to my HD. I get as far as step 7:

Once the command has finished running, your connector will appear in Zero Trust.

This doesn't happen for me - it stays empty ("No connectors installed"), even though the command ran successfully in my terminal. Any idea what I could be doing wrong?

That command runs cloudflared as a service. Generally for long-lived things that's what you want, but it may need to be started by your service manager (e.g.

systemd

systemd

or similar). For initial setup it might be easier to do it as cloudflared tunnel run <NAME>cloudflared tunnel run <NAME>

ZT team has pretty good docs on this, that seems like it'll be most helpful for you here.

Mitya•1/23/25, 7:51 PM

Thanks, I'll have a read of that. So it seems I was on the wrong lines. I was just following the guide in the docs (though I did wonder why I needed to download and install an MSI to set up a tunnel to a remote DB.) I'm trying to switch from IP-based connection to my Azure-hosted DB to use tunnels instead. Is that possible?

Isaac McFadyen•1/23/25, 8:03 PM

You'll need the Tunnel within the same VPC/network/whatever Azure calls it as the DB.

Isaac McFadyen•1/23/25, 8:04 PM

I believe with Azure you can either change the DB to be within the same VPC as a VM instance or use Private Connect (I think that's what they call it?)

Isaac McFadyen•1/23/25, 8:04 PM

Regardless, the Tunnel needs to be able to contact the Azure DB.

Mitya•1/23/25, 8:04 PM

Eeek, sounds complex. I'm no network administrator. Appreciate the info, though, I'll do some reading.

Isaac McFadyen•1/23/25, 8:05 PM

Hyperdrive can either connect over the public internet, or via a Tunnel. If you use the public internet your DB security will be weakened a bit because you'll need give it a public IP or similar. If you use a Tunnel then you can use the private IP of the DB, but whatever is running the Tunnel needs to be able to contact that private IP (that's why I mentioned VPC).

Mitya•1/23/25, 8:07 PM

Yeah at the moment my HD is connecting over public IP, which isn't ideal for the reason you mention. When you say "whatever is running the tunnel," what does that mean? Isn't that Cloudflare? I realise I'm quite ignorant here.

AJR•1/23/25, 8:07 PM

(we are working on getting over to the cloudflare IPs, to get a door #3 where you allowlist just those and could skip setting up the tunnel. it's taking a while to land, but is still coming)

AJR•1/23/25, 8:08 PM

The egress end of the tunnel, where traffic leaves it and goes to your DB, has to run somewhere. That's what

cloudflared

cloudflared

does, and that's what needs to be reachable by your DB.

Isaac McFadyen•1/23/25, 8:09 PM

^ Usually that's a VM instance hosted by you, probably on Azure as otherwise there's no way for it to talk to the DB.

Isaac McFadyen•1/23/25, 8:09 PM

That's what the MSI you were using was for. If you installed that on Windows Server (or the Linux one on a Linux machine) then Hyperdrive would route through that server to contact your DB.

AJR•1/23/25, 8:09 PM

Im using hyperdrive to cache queries to my supabase db, is there a way to cache bust a particular document. E.g. if I run a volatile query like SELECT random() FROM table WHERE id = 1234SELECT random() FROM table WHERE id = 1234 will the cache only be invalidated for that record or the whole table?

AJR•1/25/25, 8:10 PM

We don't do any purging. If you do SELECT random(), * FROM table WHERE id = 1234SELECT random(), * FROM table WHERE id = 1234 you'll get uncached results for that query. What's in the cache won't be touched either way.

AJR•1/27/25, 2:54 PM

We skip checking the cache. The delay for doing so is incredibly small, but no reason to waste the traffic.

AJR•1/27/25, 2:58 PM

For the record, we are aware this is not the best UX for bypassing cache on a single query, and are hoping to find/build something better that still plays nicely with the variety of drivers/libs we want to support.

letincho5•1/27/25, 8:15 PM

Hi, I'm using Hyperdrive + Neon + Drizzle, and I've an issue: I've to connect a new connection (const db = drizzle()...) for each query, in the same "request/worker" execution. When I not use Hyperdrive, I can have a singleton of drizzle and do multiples queries.

I'm use thats imports:
import { drizzle, NodePgDatabase } from "drizzle-orm/node-postgres";

Any ideas?

How does Hyperdrive handle replicas now?

HHello, I’m Allie!How does Hyperdrive handle replicas now?

AJR•1/28/25, 11:21 AM

For now, the same as it always has. Folks generally make separate Hyperdrives for read replicas and direct queries there at the application level.

Jeroen•1/29/25, 4:14 AM

I get a ton of errors of this form:

[ERROR]   Error: write CONNECTION_ENDED 4386caf43864cfa4ca634cafca3a4cf2.hyperdrive.local:5432

[ERROR]   Error: write CONNECTION_ENDED 4386caf43864cfa4ca634cafca3a4cf2.hyperdrive.local:5432

What causes this? I think it is on Cloudflare's end, since I have no errors in my actual database.

Happens in about 50% of cases.

Hey folks! We announced the new automatic configuration for Hyperdrive's support for private databases over tunnels. You may have caught this previously, but now you only need to setup your tunnel in your virtual network/VPC where you can access your database, and then Hyperdrive will automatically configure the tunnel to be restricted to Hyperdrive

AJR•1/29/25, 9:45 PM

I don't believe anyone is doing that, no. We haven't tested it, though some brief googling does show spanner has a "postgres-compatible" interface, which I hadn't realized. Might be worth us taking a look, at some point.
