N/A

Brody•2y ago

even erikh didnt know the answer to this question, so... dockerfile time

eirkOP•2y ago

ugh

Brody•2y ago

ask chatgpt to write you a dockerfile

eirkOP•2y ago

im looking at dockerfiles rn its not a problem how would a configuration for this look like (if railway were to add support fo rmulti binaries)?

root•2y ago

maybe a NIXPACKS_RUST_BINARY option? hold up though I'm pretty sure there's a way to do this Yes There's a NIXPACKS_RUST_BIN variable @eirk

eirkOP•2y ago

lol ty

root•2y ago

Also, Railway will respect your default_run option in Cargo.toml

eirkOP•2y ago

Brody•2y ago

there is? https://raw.githubusercontent.com/railwayapp/nixpacks/main/src/providers/rust.rs

eirkOP•2y ago

https://nixpacks.com/docs/providers/rust

Rust | Nixpacks

App source + Nix packages + Docker = Image

eirkOP•2y ago

its there tho

root•2y ago

Yes I see it in the source code

Brody•2y ago

root•2y ago

(Although I found it in the docs) It's referenced as RUST_BIN, nixpacks has a wrapper around env vars

Brody•2y ago

interesting

eirkOP•2y ago

doesnt seem to be working i think i k nope nixpacks doesnt recognize that oh coz its cached

Brody•2y ago

NIXPACKS_NO_CACHE = 1 maybe

eirkOP•2y ago

Brody•2y ago

is it dockerfile time yet

eirkOP•2y ago

yes so i figured out why it finds bins by looking thru src/bins but nooo workspaces

Brody•2y ago

why is there even multiple bins being built, sounds like a waste of time

eirkOP•2y ago

no theres multiple bins my goal is to basically a monorepo multiple packages (bins) exist, one is built

Brody•2y ago

too complicated

eirkOP•2y ago

yea too complicated for me to write patch for nixpacks to suport this dockerfile added lets see how long it takes for me to get it right coz i dont hae docker installed lol

Brody•2y ago

I don't and can't have docker installed either

eirkOP•2y ago

why

Brody•2y ago

slow-ish internet, doesn't make sense for me to download docker images locally

eirkOP•2y ago

its been two minutes

eirkOP•2y ago

crashed once no twice omfg its installing cargo deps every single time bruh any way to cache this lol

Brody•2y ago

kinda

eirkOP•2y ago

chatgpt time

Brody•2y ago

do you have nixpacks installed

eirkOP•2y ago

noo

Brody•2y ago

install it, tell it to just output the dockerfile, and then you will see how it caches

# Use the official Rust base image

WORKDIR /usr/src/myproject

# Copy the Cargo.toml and Cargo.lock files to the container
COPY Cargo.toml Cargo.lock ./

# Build the dependencies separately to improve caching
RUN mkdir src && echo "fn main() {}" > src/main.rs

RUN cargo build --release --package <your-package-name>

# Specify the entry point command to run the project

im all good ill work on copying just the binary later step 1: make it not error

Brody•2y ago

thats a good step 1

eirkOP•2y ago

so that dockerfile doesnt work for workspaces u cant build without a valid cargo.toml

Brody•2y ago

sounds correct

eirkOP•2y ago

10th build rn and its been an hour im done bot and website can go die

eirkOP•2y ago

Brody•2y ago

average railway user

eirkOP•2y ago

yk what im removing the website

eirkOP•2y ago

eirkOP•2y ago

💀

Brody•2y ago

success

eirkOP•2y ago

coz i removed the original problem no more mutlti bins

Brody•2y ago

multi bins dumb anyway

eirkOP•2y ago

aka pushing the problem to a later date

Brody•2y ago

just only build 1 bin

eirkOP•2y ago

ill need to make an api then or publish a privaate crate or dupe tons of code

Brody•2y ago

too complicated

eirkOP•2y ago

or no website but that was my entire goal too bad ig

root•2y ago

Just use default_run

eirkOP•2y ago

yeah i suppose i could modify Cargo.toml for each service i want to run i also attempted to use dockerfile again but nooooo i got it without caching but thats annoying
