N/A

the replicas option you see in your service settings has absolutely nothing to do with mongo replicas despite the same name, and it's absolutely not what you want.

are you using prisma?

I dont think so

whats prisma?

an orm

no

quite simply all i did was plug in the mongodb private uri from railway in place of the one i got from digitalocean

thats when i started getting that errror

something in your code requires a mongo replica set, you have a few options-

• remove that requirement

• deploy the mongo replica set template

• continue using the digital ocean database

i deployed the template but it's 3 instances, i only need 1

i deleted 2 of them

and now it errors this:

2024/07/29 00:09:30 server selection error: server selection timeout, current topology: { Type: ReplicaSetNoPrimary, Servers: [{ Addr: mongo1.railway.internal:27017, Type: RSGhost, Average RTT: 1288054 }, { Addr: :27017, Type: Unknown, Last error: dial tcp :27017: connect: connection refused }, { Addr: :27017, Type: Unknown }, ] }

that's what a mongo replica set is, you can not just delete them

oh

so i connect to the url of the top one

correct

will this be a lot costlier in terms of resources?

Vs digital ocean, not sure, never ran a database on DO

$15/mo is what im currently paying

its on the more expensive side i just did it with the free credit when i started and didnt care enough to switch

then it's likely you will pay less for the database on railway, but that's not a promise

yeah fair enough

plus you will not be charged egress fees for communicating with an external database

true

this looks ok so far

thanks man

btw another thing ive been wondering you may be able to answer, when i use log,Println in Go it makes the logs red for some reason on the railway UI

do u know why?

because that logs to stderr

you can create your own logger and set the output to stdout

Ok

thanks

no problem!

would something like

fmt.Println

log to stdout native?

correct

oh

so i dont have to make my own logger ill just change them all to that

perfect

if you don't actually need a logging framework, yes

though id highly recommend looking into slog, railway has great support for structured logging

good to know

just was a lot easier for me to mindlessly spam log.println

I feel ya

Hey Brody i have a follow up question

I'm trying to get into this replicaset db with mongodb compass

I'm copying this on Mongo1

you would need to use the public host and port

Where can I find that?

In the service settings

I think that template comes with a public TCP proxy

Oh so its this port

smae host it appears just a diff port

yes correct

that's a different bost

kk

mongodb makes everything so complicated

never using that shit again lol

Postgres FTW

yeah i just

im spending so mch money

just to keep this app even running

i cant afford to go recode it rn

Thats fair

railway doesnt support static ips right

google said it doesnt

You can get a static outbound ip on the Pro plan

whole reason im even not using my digitalocean db rn is because it requires you to access from a certain ip

oh yeah?

yeah -

ahh im gonna go bankrupt

whats your usecase for static outbound ips?

digitalocean has a whitelist for IPs

where im hosting the managed db

seems a lot easier than going through this whole headache

May I ask whats tricky about the mongo replica set template?

just doesnt work for me man

i have a full time job im completely drained

cant sit down for 3 hours and figure this out

Care to share what there is to figure out? would love to know how we can improve the template

i mean for me its just like

the simplicity of just being able to copy the url on the DO managed service

paste it in and have it work first time

was incredible

thats the point of a managed service obviously but

i guess the way they presented it was just less outwardly intimidating

i also noticed that once i removed the deployments i couldnt seem to get it back on

hmm, does the template not come with a public url?

you can! click the removed deployments 3-dot menu and then click redeploy

thats what i was using but it didnt work

to try and get into my mongodb compass, etc

bc also for the replica set it doesnt supply a db ui

that was a private url

the way it does for the singular mongodb instance

no i was using the regular one

i deleted it now but i saw there was a private one too it isnt the one i was using

this is a private domain

yeah thats why i got weirded out

it isnt the domain i plugged in

like i used the public one and it gave me that error message

you would have had to put the internal domain in compass in one way or another

i put this domain

look i still have it

odd, guess compass had something cached

maybe

im gonna just do this railway migration

when my business is not bleeding cash

lol

too stressed to deal with it

Fair enough
