Clayton Coleman 363b616908 Expose exec and logs via WebSockets ... Not all clients and systems can support SPDY protocols. This commit adds support for two new websocket protocols, one to handle streaming of pod logs from a pod, and the other to allow exec to be tunneled over websocket. Browser support for chunked encoding is still poor, and web consoles that wish to show pod logs may need to make compromises to display the output. The /pods/<name>/log endpoint now supports websocket upgrade to the 'binary.k8s.io' subprotocol, which sends chunks of logs as binary to the client. Messages are written as logs are streamed from the container daemon, so flushing should be unaffected. Browser support for raw communication over SDPY is not possible, and some languages lack libraries for it and HTTP/2. The Kubelet supports upgrade to WebSocket instead of SPDY, and will multiplex STDOUT/IN/ERR over websockets by prepending each binary message with a single byte representing the channel (0 for IN, 1 for OUT, and 2 for ERR). Because framing on WebSockets suffers from head-of-line blocking, clients and other server code should ensure that no particular stream blocks. An alternative subprotocol 'base64.channel.k8s.io' base64 encodes the body and uses '0'-'9' to represent the channel for ease of use in browsers.		2015-10-09 14:33:40 -04:00
