[POTENTIAL BUG] - Unable to run Quickstart demo

[CjuanRcris7]

Description

I tried to run the quickstart in Ubuntu 24.04, but when doing so, I encountered an error similar to the one reported in issue 26 [BUG - Unable to start the demo], which is currently closed. Looking at the logs, I noticed that from the file conductorScripts/deployments/platform.sh it is attempting to execute a script called /scripts/services/elasticSearchSetup.sh. In the repository, this script is actually named differently due to a capitalization: it is /scripts/services/elasticsearchSetup.sh, so the file is never found.

Even after fixing this (I renamed the script to match, so it became /scripts/services/elasticSearchSetup.sh), the make platform command still produces errors when starting the containers due to an issue with the "Maestro" service:
ERROR | org.springframework.boot.SpringApplication | Application run failed.

The error seems related to Linux cgroups and a Java NullPointerException:

Thanks for taking a look at this!

Hey! Thanks for reaching out, I suspect this is a docker version issue

If you pull the most recent commit you'll see the updated casing fix (good catch), i've also added a pre-deployment check script that you can run with:

make deployCheck

You'll get some basic feedback on whether you are set up for success (docker version + resources available)

Let me know how it goes, if pre-deployment is successful and the problem persists I can test further in Ubuntu 24.04 to see if i can replicate

Thanks again for reaching out

Hi, Mitchell:
Thanks for your help!

I ran the deployCheck script and it completed successfully, although it displayed a warning about the number of CPU cores. I’m not sure if this is a critical issue that could affect the deployment.

Since I don’t have Docker Desktop installed, I assume this CPU core limitation shouldn’t apply in my case — is that correct?

I’ve attached a screenshot of the deployCheck output, in case it helps identify whether my system might still be missing some of the recommended requirements, even though the check shows a successful result.

Regarding the first message related on the elasticsearchSetup.sh script, thank you — it’s now fixed and working properly.

However, even though the deployCheck script completes successfully, I’m still getting the same error as before when running the application: ERROR | org.springframework.boot.SpringApplication | Application run failed.

Thanks again for your support,
Juancris

Great, ok been poking around and i think i've identified the issue, working on updating the maestro image now, that should fix it.

If interested i do have a more lightweight demo branch available: https://github.com/overture-stack/prelude/tree/demo/exploration

I'll update here once i make the commit

K, I've updated the branch to use our newer version of maestro, it's written in typescript so will resolve the compatibility issue with JAVA.

Thanks for catching this, i'm seeing a few other things i'd like to update here, i'll spend some time next week updating the quickstart and the relevant guides, in the meantime i'll point you to the simpler/newer demo branch .

I'll also extend an invite to schedule a chat, always happy to hear how people are thinking about using our software and helping them get started. If interested shoot me an email at [email protected] and we can arrange a zoom call.

Of course let me know if this resolves your issue, Cheers!

Hi, Mitchell:

The quickstart branch is working perfectly now, thank you very much!
I also tried testing the demo branch, but I ran into a couple of issues, which I’m sharing here in case it helps.

First, I got a "Bad substitution" error. The Makefile uses parameter expansion like ${variable:0:64}, which only works in bash, but make was using /bin/sh by default. I tried adding SHELL := /bin/bash as the first line of the Makefile, and that seemed to work!

Then I hit an "exec format error" during the Docker build. The docker-compose.yml had platform: linux/arm64/v8 for the stage service but linux/amd64 for everything else. Since I'm on x86_64, I changed stage to linux/amd64 to match, and that solved it.

After these changes, everything works perfectly!
Thanks again for your help!
