How do I choose which binary to deploy for a rust project with multiple workspaces and binaries?

N/A

languid rune May 31, 2023, 1:07 AM

#

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

wet harness May 31, 2023, 1:08 AM

#

ugh

languid rune May 31, 2023, 1:08 AM

#

ask chatgpt to write you a dockerfile

wet harness May 31, 2023, 1:08 AM

#

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)?

quiet hare May 31, 2023, 1:10 AM

#

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

#

@wet harness

wet harness May 31, 2023, 1:11 AM

#

lol ty

quiet hare May 31, 2023, 1:11 AM

#

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

wet harness May 31, 2023, 1:12 AM

#

ye

languid rune May 31, 2023, 1:12 AM

#

quiet hare There's a `NIXPACKS_RUST_BIN` variable

there is?

wet harness May 31, 2023, 1:12 AM

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

Rust | Nixpacks

App source + Nix packages + Docker = Image

#

its there tho

quiet hare May 31, 2023, 1:12 AM

#

Yes

quiet hare May 31, 2023, 1:12 AM

#

languid rune there is? <https://raw.githubusercontent.com/railwayapp/nixpacks/main/src/provid...

I see it in the source code

languid rune May 31, 2023, 1:12 AM

#

quiet hare May 31, 2023, 1:12 AM

#

(Although I found it in the docs)

#

It's referenced as RUST_BIN, nixpacks has a wrapper around env vars

languid rune May 31, 2023, 1:13 AM

#

interesting

wet harness May 31, 2023, 1:14 AM

#

doesnt seem to be working

#

i think i k

#

nope nixpacks doesnt recognize that

#

oh coz its cached

languid rune May 31, 2023, 1:17 AM

#

NIXPACKS_NO_CACHE = 1

#

maybe

wet harness May 31, 2023, 1:25 AM

#

no

languid rune May 31, 2023, 1:25 AM

#

is it dockerfile time yet

wet harness May 31, 2023, 1:27 AM

#

yes

#

so

#

i figured out why

#

it finds bins by looking thru src/bins

#

but nooo

#

workspaces

languid rune May 31, 2023, 1:28 AM

#

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

wet harness May 31, 2023, 1:29 AM

#

no

#

theres multiple bins

#

my goal is to basically a monorepo

#

multiple packages (bins) exist, one is built

languid rune May 31, 2023, 1:30 AM

#

too complicated

wet harness May 31, 2023, 1:30 AM

#

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

languid rune May 31, 2023, 1:34 AM

#

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

wet harness May 31, 2023, 1:35 AM

#

why

languid rune May 31, 2023, 1:35 AM

#

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

wet harness May 31, 2023, 1:37 AM

#

its been two minutes

#

crashed once

#

no twice

#

omfg its installing cargo deps every single time bruh

#

any way to cache this lol

languid rune May 31, 2023, 1:42 AM

#

kinda

wet harness May 31, 2023, 1:44 AM

#

chatgpt time

languid rune May 31, 2023, 1:44 AM

#

do you have nixpacks installed

wet harness May 31, 2023, 1:45 AM

#

noo

languid rune May 31, 2023, 1:45 AM

#

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

wet harness May 31, 2023, 1:49 AM

#

dw

#

# Use the official Rust base image
FROM rust:latest

# Set the working directory inside the container
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

# Copy the entire project to the container
COPY . .

# Build the project
RUN cargo build --release --package <your-package-name>

# Specify the entry point command to run the project
CMD ["cargo", "run", "--release", "--package", "<your-package-name>"]

#

im all good

#

ill work on copying just the binary later

#

step 1: make it not error

languid rune May 31, 2023, 1:49 AM

#

thats a good step 1

wet harness May 31, 2023, 1:51 AM

#

so that dockerfile doesnt work for workspaces

#

u cant build without a valid cargo.toml

languid rune May 31, 2023, 1:58 AM

#

sounds correct

wet harness May 31, 2023, 2:01 AM

#

10th build rn

#

and its been an hour

#

im done

#

bot and website can go die

#

languid rune May 31, 2023, 2:04 AM

#

average railway user

wet harness May 31, 2023, 2:06 AM

#

yk what im removing the website

#

#

💀

languid rune May 31, 2023, 2:11 AM

#

success

wet harness May 31, 2023, 2:11 AM

#

coz i removed the original problem

#

no more mutlti bins

languid rune May 31, 2023, 2:12 AM

#

multi bins dumb anyway

wet harness May 31, 2023, 2:12 AM

#

aka pushing the problem to a later date

languid rune May 31, 2023, 2:12 AM

#

just only build 1 bin

wet harness May 31, 2023, 2:13 AM

#

ill need to make an api then

#

or publish a privaate crate

#

or dupe tons of code

languid rune May 31, 2023, 2:13 AM

#

too complicated

wet harness May 31, 2023, 2:14 AM

#

or

#

no website

#

but that was my entire goal

#

too bad ig

quiet hare May 31, 2023, 10:18 AM

#

Just use default_run

wet harness May 31, 2023, 8:42 PM

#

yeah i suppose i could modify Cargo.toml for each service i want to run

#

i also attempted to use dockerfile again but nooooo
