Command

Tag 7: the server relays a command the container asked to have run, its bytes verbatim; the client answers with one channel response per item the command produced, an error last, and the channel response finish, each relayed to the container.

The server opens this channel when the container’s proxy sends a command ask on /requests. The bytes of the command are relayed verbatim.

• The request. The tag byte 7 followed by the bytes of the command. Request states its form.
• The response. One channel response per item, an error last when the client sends one, and the channel response finish. Response states the sequence.
• The conduit. The server relays each channel response to the proxy’s /command/{channel} as one message, in order, and closes that connection when the channel finishes. The server does not read the command or an item, and does not send the command twice.
