This is mac only (for now) and will not actually do anything until syslogd is told to forward to /var/run/syslog.vsock. syslog uses a SOCK_DGRAM connection to /var/run/syslog.vsock, however vsock today is SOCK_STREAM only, so we need to "packetise" the stream. Do so by writing the datagram length as a (little-endian) uint32 before the data itself. This is slightly modelled after rfc6587 (syslog over TCP) but simplified by using a 4-byte binary value rather than ASCII digits. Arrange for vsudd to start before the logger so it is ready and waiting. Note that the code in vsyslog.go needs to be rather careful about its own logging, in particular logging forwarding failures over syslog seems likely to make things worse. Instead this file logs to the console when errors occur, this will be captured by the logging of the hyperkit VM console. Signed-off-by: Ian Campbell <ian.campbell@docker.com>
Base repo for Moby, codename for the Docker Linux distro
Initial requirements are being driven by the very minimal goal of replacing boot2docker for the new Mac app.
However these requirements are fairly small and the scope is intended to be much broader.
Simple build instructions: use make to build. make xhyve will boot it up on a Mac; unless you run with sudo you will not get any networking.
make qemu will boot up in qemu in a container.
You can build for arm, some parts still under development, make clean first, then make qemu-arm will run in qemu.
