[JVMs involved] Deploying Vespa on Railway, struggling with some limits even on a pro plan.

Question

I am trying to deploy https://docs.vespa.ai/ on railway as part of a bigger support bot https://docs.onyx.app/introduction

I use image `vespaengine/vespa:8.277.17` with moutned volume at `/opt/vespa/var` with limits of 50 gb for volume and 32gb/vcpu.

Now, I'm quite sure that because vespa itself is essentially a cluster, it runs into a problem with constraints:
```
1739796351.347337    e5113ac9d486    5    configserver    vespa-start-configserver    warning    Wanted 409600 as limit for max user processes but cannot exceed current hard limit: 99999

runserver(configserver) running with pid: 21

1739796351.441423    e5113ac9d486    22    -    vespa-start-services    info    Too low vm.max_map_count [65530] - trying to increase it to 262144

1739796351.441523    e5113ac9d486    22    -    vespa-start-services    warning    Could not increase vm.max_map_count - current value [65530] too low, should be at least 262144
```
I thought switching to pro plan would help, but nah, same thing as hobby. Can't seem to change those in Dockerfile as well.

Would really appreciate any help/workaround for this. The rest of the stack is deployed and only Vespa seems to keep having trouble with railway :/
