* https://github.com/kubernetes/contrib/pull/122 merged submit-queue into mungegithub. This fixes links to the old submit-queue location.
* Standardized to use "submit-queue" instead of "submit queue". Just picked one since both were used.
* Fixes dead link to on-call wiki.
Document how we implement kubernetes on AWS, so that configuration tools
other than kube-up can have a reference for what they should do, and
generally to help developers get up to speed.
- Refactor common and gce/upgrade.sh to use arbitrary published releases
- Update hack/get-build to use cluster/common code
- Use hack/get-build.sh in cluster upgrade test logic
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.
