I have some python files inside of a VM that will run every week to scrape info from a website. This is automated through cloud scheduler and cloud function and it is confirmed that it works. I wanted to use cloud build and cloud run to update the code inside of the VM each time I update the code inside of the Github. I read somewhere that in order to deploy a container image to a VM, the VM has to have a container-os, so I manually made a new VM matching that criteria through compute engine. The container-os VM is already made. I just need to have the container image for it updated with the new container image built with the updated code from Github.
I'm trying to build a container image that I will later use to update the code inside of a virtual machine. Cloud run is triggered every time I push to a folder in my Github repository.
I checked Container Registry and the images are being created, but I keep getting this error when I check the virtual machine:
"Error: Failed to start container: Error response from daemon:
{
"message":"manifest for gcr.io/$PROJECT_ID/$IMAGE:latest not found: manifest unknown: Failed to fetch \"latest\" from request \"/v2/$PROJECT_ID/$IMAGE:latest/manifests/latest\"."
}"
Why is the request being made for the latest tag when I wanted the tag with the commit hash and how can I fix it?
This is the virtual machine log (sudo journalctl -u konlet-startup):

This is the dockerfile:

This is hello.py:
