How can I configure a cloud storage bucket to hold data only for a single day

Question

I want to configure a bucket such that it holds data in it only for 24 hours and automatically deletes it after the time elapses. How do I do that? Can somebody help me with it?

Answer 1

Suppose you only want to keep files in a particular bucket around for just one day, then you can set up the lifecycle rule for the bucket with:

echo '{ "rule": [{ "action": {"type": "Delete"}, "condition": {"age": 1}}]}' > lifecycle_config.json
gsutil lifecycle set lifecycle_config.json gs://example-bucket

Now, any objects in your bucket older than a day will automatically get deleted from this bucket. 

You can verify the configuration you just set with the gsutil lifecycle command (other configuration commands work in a similar fashion):

gsutil lifecycle get gs://example-bucket
