Is it possible to change the docker run deploy command?

I'd like to change it to docker run --rm --init --ulimit memlock=-1:-1 jarredsumner/bun:edge to support Bun as a JS runtime on railway

We have many that use Bun on Railway. Shouldn’t need to change the ulimit memlock for it to work

Oh interesting, I haven't tried my project yet but milo was mentioning that the memlock bug prevents it from working properly on railway https://discord.com/channels/713503345364697088/1020034124326641804/1020035062772809728

Oh? CC @salvage I think that’s unrelated we had some old hosts that have since been decommissioned If not, would love more info so we can fix it

I got the memlock issue

Interesting. Need more info and a much more clear bug report on buns side. Exposing any functionality is going to be subject to security review

nebula•2y ago

i think you just need to upgrade the kernel on those hosts

JustJake•2y ago

The builders are running very new kernels 5.9+

nebula•2y ago

Linux kernel 5.11+
