Synopsis
|
|
--------
|
|
- This connection plugin provides a connection to remote devices over gRPC and is typically used with devices for sending and receiving RPC calls over gRPC framework.
|
|
- Note this connection plugin requires the grpcio python library to be installed on the local Ansible controller.
|
|
|
|
|
|
|
|
Requirements
