charmlibs.rollingops

RollingOps is a Juju charm library for coordinating rolling operations across application units.

It provides a single API to ensure that disruptive actions such as restarts, reconfigurations, or maintenance tasks are executed in mutual exclusion, with at most one unit operating at a time.

The library supports two coordination modes:

• Peer-based (application level) Uses peer relations to coordinate operations within a single application.

• Etcd-based (cluster level) Uses etcd for distributed coordination across units, enabling asynchronous, non-blocking execution of long-running operations.

To install, add charmlibs-rollingops to your Python dependencies. Then in your Python code, import as:

from charmlibs import rollingops
