Fail to Upload Large File to Google App Engine Managed VMs
After deploying a Node.js app with custom runtime to Google App Engine, when uploading file larger than 1MB, the server returns HTTP 413 status code, meaning the server is refusing to process the request because the uploading entity size is too large.
I had the following setup:
- The App Engine application is Google managed
- The application is Node.js app with custom Dockerfile
- The application Docker container runs
nodecommand directly on port 8080
After accessing the server (which changed from Google managed to user managed), and checked the Docker containers:
It looks like Nginx is running as the proxy to Node.js application. When uploading file that is larger than 1MB, the response is HTTP 413 error:
And the Nginx access log from the server:
By default, Nginx limits uploading size or
client_max_body_size to be 1MB. The default size is just too small. A short video upload could easily exceed the limit. So, how to accept file upload larger than 1MB via Google Managed VMs in App Engine? Is there a way to change the value through
app.yamlcustom runtime configuration file? Or a custom Nginx Docker container can be deployed along with the application Docker container?
