Only the directory /tmp is writable in Cloud Run. So, change the default write location to write into this directory.
However, you have to be aware of 2 things:
- Cloud Run is stateless, that means when a new instance is created, the container start from scratch, with an empty
/tmpdirectory /tmpdirectory is an in-memory file system. The maximum allowed memory on Cloud Run is 2Gb, your app memory footprint included. In addition of your file and Airflow, not sure that you will have a lot of space.
A final remark. Cloud Run is active only when it process request, and a request has a maximum timeout of 15 minutes. When no request, the allowed cpu is close to 0%. I'm not sure of what you want to achieve with Airflow on Cloud Run, but my feeling tells me that your design is strange. And I prefer to warn you before you spend too much effort on this.
