How to access Open vSwitch database server through unix socker

This article is about how to access Open vSwitch database server through unix socker, the editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

To interact with openvswitch, you can ovsdb-client list-dbs through commands, or manipulate ovsdb through api.

Ovsdb Protocol reference https://tools.ietf.org/html/rfc7047 (The Open vSwitch Database Management Protocol)

Here is an example of interacting with ovsdb through the unix sockert,json-rpc protocol

Import socketimport sysimport jsondef is_json (myjson): try: json.loads (myjson) except ValueError: return False return Truesock = socket.socket (socket.AF_UNIX, socket.SOCK_STREAM) server_address ='/ var/run/openvswitch/db.sock'try: sock.connect (server_address) except socket.error, msg: print (msg) sys.exit (1) try: message = {"method": "list_dbs" "params": [], "id": 0 } sock.sendall (json.dumps (message)) josn_result = "" while True: data = sock.recv (1024) if len (data) > 0: josn_result + = data if is_json (josn_result): break print (josn_result) finally: sock.close () above is how to access Open vSwitch database server through unix socker The editor believes that there are some knowledge points that we may see or use in our daily work.
