What it is and what it does
py-consul is a Python client for HashiCorp Consul, a distributed service mesh and configuration management system. It wraps Consul's HTTP API to let you interact with Consul's key-value store, service registration and discovery, health checks, and access control lists (ACLs) from Python code. The library supports both synchronous and asynchronous patterns and is maintained by Criteo as an active fork of the original python-consul project, which has been unmaintained since 2018.
The package is designed for developers building applications that need to integrate with Consul for service discovery, distributed configuration, or health monitoring. It handles the HTTP communication with a Consul agent and provides a clean Python interface to common operations like storing and retrieving configuration values, registering services, querying service health, and managing ACL policies and tokens.
Use it for
- Store and retrieve application configuration from Consul's key-value store with watch-based polling for updates.
- Register microservices in Consul's service catalog and query for healthy instances of dependent services.
- Manage ACL tokens and policies programmatically for fine-grained access control in a Consul cluster.
- Monitor service health by querying Consul's health check endpoints and reacting to state changes.
- Implement service-to-service authentication and authorization using Consul Connect policies.
- Build configuration management tools that synchronize settings across distributed systems via Consul.
