Having issue deploying for the first time with Dockerfile

Hey! I just deployed my application successfully and the instance logs say it is running on port 8000 (which I get locally too so it is working as expected). But when I go to the domain I setup -- https://api.wriggly.io/ -- I get the following message "Application error: a client-side exception has occurred (see the browser console for more information)." This is my deploymentID 456ea53 Additionally, is this potentially an issue with my Dockerfile? I know when I run the dockerfile locally I run docker run -p 8000:8000 {containername} to map it to the external port 8000. does that matter?

you want your app to listen on $PORT not 8000

oh got it do I configure this in environment variables? also since my dockerfile sets it up to run on port 8000 will I need to update my dockerfile to read this var ?

Brody•2y ago

send the dockerfile?

ErikTOP•2y ago

oh got it -- what looks wrong ?

Brody•2y ago

few things you are using the root as the workdir you want WORKDIR /app remove the EXPOSE and in app.js have it listen on process.env.PORT || 8000

Brody•2y ago

you've changed the workdir right?

ErikTOP•2y ago

uhhh this is the new docker file I need to make some requests against the service to ensure it works but it looks correct
