Check last S3 file
A useful script that search for last file in a s3 bucket and check size and last edit timestamp. We use this with a cron job for check that our backups are up to date.
Following environment variables are mandatory:
TIMEZONE= // ex. Europe/Rome
AWS_ACCESS_KEY_ID=
AWS_SECRET_ACCESS_KEY=
AWS_REGION= // ex. eu-west-1
BUCKET= // Only the bucket name ex. Backups
PATH_PREFIX= // You can insert here subpath and the name prefix ex. /databases/my-database
OLDER_THAN_MINUTES= // ex. 60 for 1 hour
SMALLER_THAN_MEGABYTES= // ex. 100 for 100MB
Usage
docker run --env-file .env leen15/check-last-s3-file
And it responses with something like:
Check last file in:
Bucket: backups
Prefix: databases/my-database
Older than: 60 minutes
Smaller than: 100 MB
Files in bucket: 4
Most recent file is:
Name: my-database.2019-11-22-00-10-09.native.dump.bz2
modified at: 2019-11-22 01:10:11 +0100 CET
Size: 50 MB
[ERROR] The file is older than max allowed. ( 13h57m23.59s ago )
[ERROR] The file is smaller than min allowed. ( 50 vs 100 MB )
