ObjInSync

Daemon to continuously and incrementally synchronize a directory from remote object store to a local directory.

Usage

objinsync pull --exclude '**/__pycache__/**' s3://bucket/keyprefix ./localdir

When running in daemon mode (without --once flag), a health check endpoint is served at :8087/health and a prometheus metrics endpoint is served at :8087/metrics. You can use --status-addr to override the binding address.

Objinsync also comes with builtin Sentry integration. To enable it, set the SENTRY_DSN environment variable.

You can also run objinsync in pull once mode, which behaves just like aws s3 sync:

objinsync pull --once s3://bucket/keyprefix ./localdir

To use with Minio instead of S3, you can set --s3-endpoint and --disable-ssl flags for pull command as you see fit.

The -i or --interval flags allows to configure the pull time interval, which is 5 seconds by default:

objinsync pull --interval 20s s3://bucket/keyprefix ./localdir

Enable debug logs by setting the DEBUG environment variable DEBUG=1 objinsync pull ...
