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•3y ago

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

JustJake•3y ago

The builders are running very new kernels 5.9+

nebula•3y ago

Linux kernel 5.11+

JustJake•3y ago

Fkn hell

nebula•3y ago

💀

JustJake•3y ago

K probably won’t happen for a bit then. At one point this worked.

nebula•3y ago

buns just using a ton of new stuff ig

JustJake•3y ago

Yea I’ve mentioned it to Jarred before but compatibility is make or break

HarrisOP•3y ago

What would be the timeframe for migrating to 5.11+? Guessing I shouldn't hold my breath for it lol I'd love to switch my project over to bun, but keeping it working with railway is more important.

JustJake•3y ago

Yea not gonna happen in the next month+

HarrisOP•3y ago

😦 makes sense though

nebula•3y ago

what kernels are the deployment hosts running?

JustJake•3y ago

Varies. None of them are going to be 5.11+ though So, suppose buns out until compatibility is solved

HarrisOP•3y ago

anything I could do to help this effort?

JustJake•3y ago

You’d have to ask Jarred from Bun

My goal for this week is to ship bun’s new http client. It impacts bun install and fetch() More reliable, faster, and it fixes the error about memlock/Linux kernel version incompatibility

Sounds like he’s on it lol

he responded to our open issue before he tweeted about it 😄

JustJake•3y ago

Give it a go and let us know! If it's green we can include it in the changelog this week

HarrisOP•3y ago

will do discord.js doesn't support bun so can't test it properly on my one project could potentially try it on milos test repo

yeah give it a shot

Is it possible to change the docker run deploy command?
