This is a forklift of the nova novncproxy service to act as the noVNC
front-end to graphical consoles.
The service does the following:
- serves noVNC web assets for the browser based VNC client
- creates a websocket to proxy VNC traffic to an actual VNC server
- decouples authentication traffic so that the source server can have
a different authentication method than the browser client
The forklifted code has been adapted to Ironic conventions, including:
- [vnc] config options following Ironic conventions and using existing
config options where appropriate
- Removing the unnecessary authentication method VeNCrypt, leaving only
the None auth method.
- Adapting the ironic-novncproxy command to use Ironic's service launch
approach, allowing it to be started as part of the all-in-one ironic
- Replace Nova's approach of looking up the instance via the token.
Instead the node UUID is included in the websocket querystring
alongside the token
- Removing cookie fallback when token is missing from querystring
- Removing expected protocol validation in the websocket handshake
- Removing internal access path support
- Removing enforce_session_timeout as this will be done at the
container level
