When I deploy my docker container to cloud run it will run for about 10 minutes and then it crashes.
I was wondering why it is doing this I have set a port so it seems like it should work. Is my Docker file incorrect.
Cloud Run error: The user-provided container failed to start and listen on the port defined provided by the PORT=83 environment variable. Logs for this revision might contain more information.

I realise I was only adding port mappings to containers not to the images. But I tried exposing one and I got the same result, I’m sure I am making a mistake in my docker file in regards to how I’m exposing the ports.

Please use the </> to format code (or read about using Markdown). I’ve done that for you now. Also, I removed the almost-duplicate post about the same problem. Please note the pencil icon to edit your own posts if nobody answered yet. Success!
Check if your container is listening for requests on the expected port as documented in the container runtime contract. Your container must listen for incoming requests on the port that is defined by Cloud Run and provided in the PORT environment variable. See Configuring containers for instructions on how to specify the port.
Check if your container is listening on all network interfaces, commonly denoted as 0.0.0.0.
Hi, what I find confusing about cloud run is that you have to upload the images and it builds the containers for you there. You can’t upload a container which has the port assigned.
My understanding was that
EXPOSE 3000/tcp would allow my image to build the correct container within the cloud as long as you set the container of the VM to 3000. And it does run successfully - it just then crashes after 4 or 5 minutes.
I have tried a few different ways to make sure the ports are being listed to but I'm not sure how to set or check the same way I can with a standard container that I have built on my desktop.

Should this Docker file not allow the image to listen to port 8080?
