Issue when deploying node app using docker

I'm having issues when I'm trying to deploy a node app with docker, when I build and run the image locally it runs fine but on railway it shows me the build the built node file not found. Also, this is something that is fairly recent and my docker config file hasn't changed so not sure why this might be happening. Help appreciated, thanks!

Solution:

ah thanks, just found out the cause of the issue. It was a change that was pushed yesterday that resulted in dist folder not being generated in CI builds which is why it worked locally but not when it was deployed via CI.

033f39f1-9797-405f-88f8-343ca4ac4254 For some context, the build succeeds but when the cmd command is ran is when the error is thrown and the healthcheck fails, causing the deployment to fail.

Please send the dockerfile and the error that is thrown

Hey, thanks for the quick reply! Is there a private portal that I can send it through? nvm, sorry I just realized I don't have any sensitive info in the docker file so here it goes

just realized I don't have any sensitive info in the docker file

i would sure hope so 😆 can you try removing the WORKDIR /app/apps/api line

JayOP•8mo ago

sure, I'll try it and be back in a bit! appreciate the quick responses! okay, so it just finished a deployment but I'm still getting the same error. I updated the dockerfile to remove WORKDIR /app/apps/api and updated the CMD command to run node apps/api/dist/index.js but I'm still seeing the same error.

Brody•8mo ago

are you sure the dist folder is going to end up in /app/apps/api?

JayOP•8mo ago

mhm, yeah I checked the built image locally and the index.js file to be run is inside the /app/apps/api/dist directory.

Brody•8mo ago

chuck in some ls commands and see what that prints on railway?

JayOP•8mo ago

I'm sorry but I don't know how to do that in railway? is there an article i can follow to see how to do so?

Brody•8mo ago

RUN ls -l

JayOP•8mo ago

ah, gotcha in the docker image, right?

Brody•8mo ago

Dockerfile

JayOP•8mo ago

yes, got it thanks! will try and get back with what shows up

Brody•8mo ago

sounds good
