Running go program on Google Cloud Run without listening for incoming HTTP requests

Question

I wrote a Go program which doesn't need to retrieve external http calls at all by default. I tried to deploy it on Google Cloud Run and received the following error:

The user-provided container failed to start and listen on the port defined provided by the PORT=8080 environment variable. Logs for this revision might contain more information.

I understand it happens because my code doesn't provide a port. As this answer states:

container must listen for incoming HTTP requests on the port that is defined by Cloud Run and provided in the $PORT environment variable

My question is what can I do if wouldn't like define any ports and just want to run the same code I run locally? Is there an alternate solution to deploy my code without it, or I must add it anyway if I want run the code from Cloud Run?

Answer 1

For containers that do not require an HTTP listener (HTTP server), use Cloud Run Jobs.

• Cloud Run Jobs is in preview.
• Your Go program must exit with exit code 0 for success and non-zero for failure.
• Your container should not listen on a port or start a web server.
• Environment variables are different from Cloud Run.
• Container instances run until the container instance exits, until the task timeout is reached, or until the container crashes. Task timeout default is 10 minutes, max is one hour.
