Production Checklist
Cloud Run is in Alpha, which means APIs may change in any version and documentation is not yet finished. See the changelog to stay up to date with breaking changes.
import {DefaultTimeout} from '../../components/cloudrun/default-timeout';
You have implemented your solution with Remotion Cloud Run and are ready to launch your project into the world. Congrats! Before you go live, go through this checklist to make sure Cloud Run is running stable.
Optimizing for memory
Adding too much memory to your Cloud Run services can make rendering more costly. Reducing the memory of your service by 25% will also decrease your cost by 25%! Redeploy your service multiple times and lower the memory size as much as possible until you feel you hit the sweet spot between low costs and confidence that your video will render reliably.
Maximum file size
The output file size on Cloud Run is constrained by the memory limit, minus the size of the supporting software for Remotion Cloud Run running on the service. Adjust the disk space parameter of Cloud Run to accommodate for the maximum video length that you would like to support. Test the file sizes of your outputs and make sure they don't run at risk of exceeding the limit. If your video is based on user input, prevent your users from rendering very long videos that would exceed the space available in Remotion Cloud Run.
Permissions
Make sure your GCP Service Account only has as many permissions as needed and store your credentials as environment variables. Review the Permissions page to see what the minimum amount of permissions is.
Selecting the right concurrency
Using the Remotion API, services will be deployed with a concurrency of 1 (i.e no concurrency). This is to ensure no issues arise from shared CPU and memory of unrelated renders. If you wish to change this, you will need to click 'Edit and Deploy New Revision' from within the Cloud Run section of the GCP Console, and select the desired concurrency.
Selecting the right instance limit
By default, the Cloud Run service will have a minimum number of instances set to 0, and a maximum instance limit of 100. If more than 100 simultaneous render requests are made at once, a 503 service unavailable will be returned. Read more about the instance limit here.
Bucket privacy
By default the rendered videos are publicly accessible in your bucket. Use the privacy setting in renderMediaOnCloudrun() and renderStillOnCloudrun() to make renders private if you'd like so.
Rate limiting
Consider if it's possible for a user to invoke many video renders that will end up on your GCP bill, and implement a rate limiter to prevent a malicious actor from rendering many videos.
Timeout
The default timeout for your Cloud Run service is
Valid Company license
Companies with more than 3 people need to buy cloud rendering seats in order to use Remotion Cloud Run. Please familiarize yourself with the license and buy the necessary cloud seats before launching.
