DroChange

DroChange is an open‑source configuration management tool designed to facilitate dynamic, real‑time changes in distributed computing environments. First released in 2019 by the DroChange Foundation, the project has since evolved into a community‑driven stack that supports a range of deployment targets, including Kubernetes, Docker Swarm, and traditional virtual machine clusters. The software is written primarily in Go, with a companion Python SDK that allows users to script complex change workflows.

At its core, DroChange provides a declarative model for specifying desired state. Users define configuration changes in YAML files, which DroChange then reconciles against the actual state of the system. The tool incorporates a robust event‑driven architecture, issuing WebSocket notifications to registered clients whenever a change cycle completes. This feature is particularly useful for audit logging and for integrating DroChange into continuous‑integration pipelines. DroChange also supports rollback mechanisms via snapshotting, allowing administrators to revert to previous configurations with minimal interruption.

Security is addressed through role‑based access control, with support for OAuth2 authentication and integration with existing directory services like LDAP. The project is distributed under the Apache License 2.0, encouraging both institutional adoption and commercial use. Documentation is maintained in a dedicated wiki and includes tutorials on common use cases such as blue‑green deployments, canary releases, and policy‑driven configuration enforcement.

Since its inception, DroChange has been adopted by several mid‑size cloud service providers and is actively maintained on GitHub, where contributors submit bug reports, feature requests, and pull requests. The development roadmap highlights planned support for multi‑cloud orchestrators and a dedicated mobile management UI.
