Build a detonation velocity website with Cloud Run and Python (Flask)
Build a detonation velocity website with Cloud Run and Python (Flask)
I created a website for #Weekend Hackathon, so I decided to publish it. There are many options such as AWS and rental server, but this time I decided to use Cloud Run, which is serverless and can be operated almost free of charge.

Supplement
In operation, create deploy_run.sh so that it can be deployed all at once. Since the local Docker environment can be published as it is, it can be published at explosive speed Also, Cloud Run is a charge per access, so it is ideal for the initial release. Please try it.
