Project won't deploy

Are you using nixpacks or a Dockerfile?

It looks like you are running a .NET 8.0 project on the wrong version (.NET 6.0?)

I do have a docker file but I saw it building with nix packs

That's the build log.

Welcome to .NET 8.0!

SDK Version: 8.0.100-preview.5.23303.2

set the ENV NIXPACKSCSHARPSDK_VERSION=8.0.311

It shouldnt use Nixpacks if you have a dockerfile though

This is my Dockerfile, make sure its in your base directory (of your github repo)

FROM mcr.microsoft.com/dotnet/sdk:8.0 AS build
WORKDIR /app

# Copy and restore dependencies
COPY . .
RUN dotnet restore

# Publish the application
RUN dotnet publish -c Release -o /out

# Use a lightweight runtime image
FROM mcr.microsoft.com/dotnet/aspnet:8.0
WORKDIR /app
COPY --from=build /out .

# Set the entry point
ENTRYPOINT ["dotnet", "Discord Bot.dll"]

This is mine:

`# Build-Phase mit SDK
FROM mcr.microsoft.com/dotnet/sdk:8.0 AS build
WORKDIR /src
COPY ["SubBot/SubBot.csproj", "SubBot/"]
COPY . .
WORKDIR "/src/SubBot"
RUN dotnet publish "SubBot.csproj" -c Release -r linux-x64 --self-contained true -o /app/publish /p:PublishSingleFile=true /p:PublishTrimmed=false

Minimaler Runtime-Container – ohne dotnet runtime

FROM debian:bullseye-slim AS final
WORKDIR /app
COPY --from=build /app/publish .
RUN chmod +x SubBot
ENTRYPOINT ["./SubBot"]`

and it lies here

Is that the base directory for your repo? For mine, I have the Dockerfile in the solution directory.

This is at the top

should i place it there?

Yes, that is the git repo's base directory since it has the .git folder in it

Sorry, i feel utterly dumb asking this questions…

Nah its fine

now im getting this error:
✕ [build 6/6] RUN dotnet publish "SubBot.csproj" -c Release -r linux-x64 --self-contained true -o /app/publish /p:PublishSingleFile=true /p:PublishTrimmed=false

I believe you just need to change all of the SubBot.csproj instances with ./SubBot.csproj

Since you moved the Dockerfile to a different directory

in my dockerfile aight?

Yes

should look like that

i changed my dockerfile to this self containing thing. should i try yours and change the names obviously?

Wait sorry it should be ./SubBot/SubBot.csproj

Uh

Yeah one sec

This is a pretty bare bones one

This is the official visual studio one

I have my project and solution in the same directory so you would have to change the stuff around slightly

oh boi

then im trying that offical one

When I created my newest project, I set it up to use the dockerfile by default

on railway?

On visual studio

I dont think you can change it now

But ill generate a dockerfile for you

i haave this now

I would assume that would work if you change the RUN dotnet line to have "./SubBot/SubBot.csproj" and the entrypoint to be ["dotnet", "SubBot.dll"]

why dotnet?

Dotnet = .NET

looks like this now

Its the CLI for c#

That looks correct

pushing it.

i mean i have no clue what those lines excatly do 😄 so yea…

should i remove the global.json?

yeah

its interfering with it

<:KEKW:947842215005286460>

oh boi i guess its a path thing

uhhhhhhhhhhhhhhhhh

yea 😄

Oh okay im stupid

No

IM stupid!

RUN dotnet build "SubBot.csproj"

do that

I told you to change that one

publish aswell?

and the same with publish

yea

it's taking longer now

ahh

its active but crashed

The configuration file 'appsettings.json' was not found and is not optional. The expected physical path was '/app/appsettings.json'.

need to replace the config logic with the enviroment logic from raailway for tokens i guess

Or you can put it in a volume

But for tokens definitely use ENV

Do i place them into the service variables or shared variables?

service unless you are using the token across multiple services which is unlikely (e.g. you have a main bot and an seperate API service)

if you arent planning on using ENVs on more than one service then use the service variables

nah its just a simple bot for registering substitute players.
i need to connect a database now.
That was the reason to try railway because i didnt want to host a db myself locally

Do you have a .net bot with dsharpplus as well?

i created a custom discord api wrapper package for my bots

i dont use any packages

Ah, okay nice.
And if I read thatr correctly i log to Console.WriteLine(); to see it in Railway?

Yes

ah and your were a huuuuuuuuge help!!!

Thank you so much!

I was bored

No problem

Best thing that could happen

very

is it possible to run an sql file to fill a database here?

ive never tried it

you could probably use an external program like tableplus to run SQL queries on the database

Ah yea, i can connect to the db from my computer and run it there. im using heidisql

that should work

yeah that should work

the database should have a public and a private url

use public to connect to it externally and the private to connect to it on your main program when running on railway (to save on egress costs)

postgresql://postgres:@metro.proxy.rlwy.net:42005/railway

Like this?

yes

that should be the public one

the internal one is just a variable

${{ Postgres.DATABASE_URL }}

Yup

oops i just saw i used mysql back then 😄
Reviving the bot atm 😄

_connectionString = enviroment.mysql.DATABASE_URL; MySqlConnection connection = new MySqlConnection(_connectionString); try { await connection.OpenAsync(); Console.WriteLine("Die Verbindung zur HL-Datenbank wurde erfolgreich geöffnet."); return connection; } catch (Exception ex) { Console.WriteLine("Fehler beim Öffnen der Verbindung zur HL-Datenbank: " + ex.Message); return new MySqlConnection(); }

that would be my guess to connect internally

Yes, Is environment a custom class or?

it should be

Environment.GetEnvironmentVariable("DATABASE_URL")

ah yeas. i meant that 😄

do i have to insert the databse variables into my service variables or are they "gobally" by default?

you would have to insert them

${{MySql.DATABASE_URL}}

Or whatever

ahhh now i see the connection

Thank you!!!

How do you debug your bot when its running on railway?
Is it the old write logs, deploy and repeat thing? 😄

ofcourse

love that <:KEKW:947842215005286460>

im used to it

oh bro thanks again

no problem!

relatable

looks like we’re good to call this solved?

Yup
