The “manila-share” component in OpenStack Manila refers to the backend service responsible for handling the actual sharing and management of file systems. It is deployed on storage nodes and interacts with the underlying storage systems to provide file storage services to OpenStack users.
Here are some key aspects and functionalities of the OpenStack Manila-share component:
- Shared File Systems: Manila-share allows users to create and manage shared file systems. These file systems can be accessed by multiple instances within an OpenStack cloud environment simultaneously. The shared file systems can be used for various purposes such as data sharing, application deployment, and collaboration.
- Backend Storage Support: Manila-share integrates with different storage backends, including NFS (Network File System) and CephFS (Ceph File System), to provide the shared file system services. It supports a variety of storage drivers that communicate with the underlying storage infrastructure and handle tasks like file system creation, deletion, and access control.
- Multi-Tenancy: OpenStack Manila implements multi-tenancy, allowing multiple users and projects to share the same infrastructure while maintaining isolation and security. Each user or project can create and manage their own set of shared file systems without interfering with others.
- Access Controls: Manila-share provides fine-grained access control mechanisms to ensure secure sharing of file systems. It supports access rules and security features like access-level permissions (read-only or read-write) and IP-based access restrictions. These controls enable administrators and users to define who can access the shared file systems and what level of access they have.
- API and CLI: The Manila-share service exposes a set of APIs (Application Programming Interfaces) that allow users to interact with the shared file system service programmatically. Users can create, delete, and manage shared file systems, as well as perform operations like mounting and unmounting the file systems. OpenStack also provides a Command-Line Interface (CLI) tool for easier management and administration of the shared file systems.
- Integration with OpenStack: OpenStack Manila integrates with other OpenStack services such as Keystone (identity service), Nova (compute service), and Horizon (dashboard) to provide a seamless user experience. Users can leverage Keystone for authentication and authorization, Nova for managing instances that access the shared file systems, and Horizon for a graphical interface to manage the shared file systems.
In summary, the “manila-share” component in OpenStack Manila is responsible for managing shared file systems, integrating with different storage backends, enforcing access controls, and providing APIs for users to create and manage shared file systems in an OpenStack cloud environment.
