Accessing files inside the volume

what's the best way to export build artifacts from one service to another? during build process, a tls.cert and a .macaroon file are generated, which i need to pass to another service to be able to connect them as i understand, volumes can't be shared, they are scoped per-service, right? Brody — Today at 14:23 correct, if you could share a volume to multiple services (you will be able to at some point, its planned) then you just write those files to the volume and read them back from the other service, but thats not currently possible so maybe make those files available via a local only api? then your service can just download the files from the other service i am using a pre-built docker image for that piece of the system, so that's gonna be tricky is there a way to mount a volume remotely? i can just generate artifacts once and manually send them using env variable Brody — Today at 14:28 like you could just generate those files locally and upload them into the volume? no, the opposite way, that service autogenerates them on start, if they're not present, but then i can keep the volume in place so that the artifacts don't change Brody — Today at 14:31 unless im misunderstanding something, that is what a volume is for, persistent storage yeah, but i also need to be able to pass those files to another service using volume can help me not needing to pass them on each restart is there any way to read files from a volume, other that editing the code of the service?

so that's how i had it in my docker-compose

BBrody

so at the end of the day, two services still need to be able to access the same file system right?

Ccaffeinum

and I need to have these two files to connect

Ccaffeinum

macaroon is basically a cookie, and tls.cert is a custom signed ssl cert required to connect them lnd is not a service i control, i can edit docker file slightly, but i don't wanna change the source code accessing the same file system is not super required, it's just how it's done in docker compose, cause that was the easiest i can pass the file content using env variables, it's not a problem cause it's only two files

BBrody

9/7/2023

right but both services still need to access the same filesystem

Ccaffeinum

9/7/2023

no, the only interaction was passing these two files on init on go-stroom boot, it needs to have these two files

BBrody

9/7/2023

i cant see how that doesnt mean the same thing as what im saying

Ccaffeinum

9/7/2023

i mean if it's possible, yes, they need to access the same file system but you said it's not, so i am thinking of other ways to pass this data e.g. during runtime, there's no need to access the same file system, it's only a boot-time requirement

BBrody

9/7/2023

i think youll need to combine the two services into one for now, with something like multirun or parallel

Ccaffeinum

9/7/2023

i don't want to mix two codebases, it's gonna be a too much of a mess again, i don't need to access the same filesystem, i just need to be able to download the file once from the volume

BBrody

9/7/2023

aren't they both docker images?

Ccaffeinum

9/7/2023

oh, so you mean create another docker image that bundles them together into one docker image, and run that docker image?

BBrody

9/7/2023

indeed

Ccaffeinum

9/7/2023

ooooph

Brody — Today at 14:28 like you could just generate those files locally and upload them into the volume?

Okay, and is this possible?

BBrody

9/7/2023

yes https://railway.app/template/Nan7Bs

By default, the storage location is set to the storage subdirectory in the root of the volume, but by setting a service variable USE_VOLUME_ROOT to 1 you can opt to use the root of the volume as the storage location instead

Ccaffeinum

is there the same thing, but w/ bash access so that i can ping local services? wait, so you're telling me i can actually connect a volume to one service, let it generate files, then disconnect the volume and reconnect to another service?

BBrody

9/7/2023

yes

Ccaffeinum

9/7/2023

this would actually solve my problem

BBrody

9/7/2023

oh i though you knew that

Ccaffeinum

9/7/2023

that's why i was saying i don't need simultaneous filesystem acces i didn't know that cause i didn't reliase it's possible to move them
