<!here> Calling all builders! We are looking for software engineers, LLM enthusiasts and data/AI app builders to join Backdrop Build, a 4-week program (free, online, low time commitment, remote, and async) where folks join forces to build and launch their projects on Ploomber Cloud. We would love to support members in our community build and deploy projects https://backdropbuild.com. Please send me a DM if this is of interest to you - if you have questions on the program and the types of projects that we will build and deploy let us know!

Hello! I'm trying to run a simple Flask + Torch app (lightweight, 300kb zip file including 100kb trained model, very small) and it fails deployment with: The container failed due to insufficient memory

Is there way to set papermill "--execute-timeout=-1" option in Ploomber-engine. My long running notebook get killed with timeout error

137 on gnu/Linux

Say I'd like to modify a notebook node significantly enough that I can't just rinse and repeat with

ploomber build

until it works as intended. How should I go about running it in isolation as a proper notebook in VSC or jupyter, and still having benefits of the information in

upstream = [ 'get', ...]

preamble and perhaps in

pipeline.yaml

and

env.yaml

? I could add some shim code to inject desired inputs into

upstream

, only to excise it later, when not needed anymore, but I'm hoping you guys could suggest a tried and proved pattern...

what is this ploomber

how it works

Hello. Am I missing something with the ploomber cli, or it is not possible to specify a name for an app from the cli on a paid plan?

Hi all, deploying an app, previously worked fine from another dev account.. now stuck in the final stage, how long does this usually take?

"Serving traffic: Pending" ...

Hi, i cannot redeploy an app that was running for months (r-f66c3f57). With the error:

Bad Request - Failed to read your file app/aws/__init__.py, please reach out for support if you need help

Can you please have a look? Thanks.

Hello, when I deploy everything seems to be fine but after the deploy stage it's stuck in "Serving traffic: Pending". Yesterday the app was up & running, while since this morning it's stuck in the "provisioning" stage.

I am receiving

Error: An error occurred: We apologize, but our system is currently down. Please try again later. (Request ID: r-0f47eb04)
If you need help solving this issue, send us a message: <https://ploomber.io/community>

I'll come back tomorrow to see if this is worked out!

Hey folks. Does Envoy sidecar being used for Ploomber services? If that's the case, can I modify the timeout on the Envoy proxy? When I am streaming LLM response, it times out at 15 second so I am not getting entirety of response back

I need help with this code

Hi, one of my apps (small-sun-0625) just stopped working. I havent deployed or anything in a while. I redeployed but it is still not reachable. Can you please check? Thanks a lot. Its just a react frontend.

It worked yesterday and stopped again to work today. Can someone have a look please. Thanks

Hi, how to ignore files in the zip file created with ploomber? gitignore file is not taking into account apparently and I get the limit to 50Mb size, so no deploy is posssible.

How do you guys define "Idle apps are removed": After 1 week of inactivity ?

Is the open source Ploomber project still under active development? I went to Ploomber.io and it looks like the docs are all about Ploomber Cloud. It looks like there's not much development happening on it nowadays on Github. Thanks!

I see this error in my Dash app and according to online forums it may be due to an old version? https://community.plotly.com/t/dash-2-9-2-keyerror-callback-function-not-found-for-output-does-not-make-any-sence-in-docker/74254/8

Is there any documentation about "persistent storage"? I've tried looking at https://docs.cloud.ploomber.io/ but didtn't find anything. Thanks!

Hi. May I ask what is the infrastructure update about you mentioned in the email? How will it affect the performance of the apps?

<!here> 🚀 Ploomber.io Just Got Even Better! 🚀 We’ve made some big improvements to our infrastructure, and deployment times are now faster than ever! 🎉 Plus, you can now launch a PostgreSQL database directly from Ploomber.io, making it even easier to manage your data applications. Try it out and let us know what you think! 🚀✨ You can write ideas here on stuff that are currently missing if Postgres isn’t it! #product-update #ploomber

I see this error on my website:

upstream connect error or disconnect/reset before headers. retried and the latest reset reason: remote connection failure, transport failure reason: delayed connect error: 111

and this in the Ploomber logs:

2025-04-22T13:37:52.107000+00:00 - /srv/entrypoint.sh: line 33: unexpected EOF while looking for matching `"'

The app was working earlier, and I haven't redeployed since

I deleted my old project, which was on a custom domain, and created a new one. I am not able to add my old custom domain (now unused) to this one: Conflict - hosted zone already exists (Request ID: r-db29fbc0) also I can't be sure but I think when I redeployed with new source code, the old source code from a previous upload was being deployed
