Workers have no where near the power needed to be a runner

Cyb3r-Jak3OP•3/19/25, 1:34 AM

And Cloudflare doesn't offer compute that other providers do

peterviszt•3/19/25, 1:38 PM

Where should i report a "bug"? The example code here is wrong

So how does Cloudflare Builds work?

And cannot that be used for running GitHub workers?

Chaika•3/19/25, 3:34 PM

Once it launches maybe, depends on how easily they give it to the public

Chaika•3/19/25, 3:35 PM

might not make sense cost wise and such

LordSilver•3/19/25, 3:57 PM

I thought Cloudflare Builds had no coldstart at all, but I read that's 10s now?

LordSilver•3/19/25, 3:57 PM

LordSilver•3/19/25, 3:59 PM

Kinda in-line with GitHub Actions runners hosted on Azure to be fair.

Chaika•3/19/25, 4:00 PM

Cloudflare workers don't (well.. mostly), maybe that's what you're thinking of?

Chaika•3/19/25, 4:01 PM

they advert Workers having no cold start in quite a few places but never builds as far as I know lol

Walshy•3/19/25, 4:02 PM

yeah workers != builds

Great tip, 100% agree with it

joris•3/19/25, 7:01 PM

lol, i literally created a library yesterday for that reason

joris•3/19/25, 7:01 PM

for easy ssr in workers using html templates

LordSilver•3/19/25, 8:13 PM

so Builds is just normal VMs, not V8 isolate

Walshy•3/19/25, 8:48 PM

yeah, it's just a build server - it's basically just GitHub Actions and Workers is the app GitHub Actions deploys

When using the new automated worker builds, how is it possible to access configured build secrets? For example I would like to execute drizzle migrations on push to main, before deploying to workers. But I don‘t get the database url within drizzle config currently!

Hi all, I have a question about Logpush and Workers work. I wanted to customize the sending of my Workers logs to Grafana, for this I found an option to set up a special Worker that will take requests from Logpush, format them and send them to Grafana Loki. I have enabled Worker Logs - Enabled and Logpush - Enabled in my Worker Logs, and I have a business subscription and a workers subscription in my account. I have set up a Job in Logpush, but I can only see test messages in Grafana (apparently they are created when the Job is created), but after that I don't see any messages. What could be the reason for this behavior? I also added console.log(); but it didn't help, I think I did everything according to the instructions but no positive result, has anyone experienced this?

HHello, I’m Allie!This? https://developers.cloudflare.com/workers/ci-cd/builds/configuration/

Exactly!

Hello, I’m Allie!•3/20/25, 2:38 PM

Just to confirm, did this answer your question?

Ah okay, sry I thought that was just to confirm which build configuration I meant. Question still there. Within the link you provided there‘s an section about build configuration and how to provide build time secrets and variables. I added a secret and try to access it via process.env.DATABASE_URL but it seems like there is no issue available. So I‘m wondering how to get access to this issue from within the drizzle.config.ts file to execute the Migration?

darkpool•3/20/25, 4:32 PM

For a worker that is just an entry-point for other workers to invoke via RPC how come we have to add a fetch method?

How come we cant do something like:

import { WorkerEntrypoint } from "cloudflare:workers";
export default class extends WorkerEntrypoint {
  add(a, b) { return a + b; }
}

import { WorkerEntrypoint } from "cloudflare:workers";
export default class extends WorkerEntrypoint {
  add(a, b) { return a + b; }
}

I'm following the code examples from the alarms API, where I only

setAlarm

setAlarm

getAlarm()

getAlarm()

returns

null

null

. I identified a durable object where

getAlarm()

getAlarm()

was consistently returning a date several weeks in the past though. Is this supposed to be possible? Does this mean that alarm reached its retry / backoff limit? What's the best practice in this case? Current workaround is to re-set the alarm if its date is too far in the past.

I’m making a cf bot to handle http interactions that are sent by discord (a bot, or app if you want). When discord sends an interaction, I return a new response. Is it possible to see the response discord sends back about the response I sent to discord? (If that makes sense)

.gwapes•3/20/25, 10:11 PM

I’m dumb

Tincan•3/21/25, 4:55 PM

Will make a "help" topic if need be but I have some headers being set in _headers file which I can see in the CF dashboard. Looks as expected, but these headers are not being set when viewing with ZAP test or $ curl -I <domain>.

Any idea why CF might be picking themup from the file ok but then not applying to the actual deployment?

Tincan•3/21/25, 5:10 PM

Perhaps it just takes some time to propegate?

juanferreras•3/21/25, 11:45 PM

Browser Rendering (cloned puppeteer) used to have a weird color shift when using

this.client.on("Page.screencastFrame"

this.client.on("Page.screencastFrame"

. I was procrastinating on creating a issue on GitHub but it looks like it's been silently fixed! Just wanted to say many many thanks on that one to who ever was

How to create Astro Template Minimal ?
npm create cloudflare@latest -- mycode --framework=astro

Evgeny•3/22/25, 10:28 AM

Interesting RPC behavior that doesn't seem to be documented anywhere... The caller gets terminated with "Exceeded CPU Time Limits" error after 15 mins wall time (~30ms CPU time) and the callee (server) shows "Client Disconnected" with ~40ms CPU time in the metrics. The callee produces healthy logs for 15 mins, waking up every 30 seconds to check a job status and to extend its life with setTimeout. The caller works fine if the job takes less than 15 mins wall time or no RPC is used.

Workers have no where near the power needed to be a runner
