We don't actually build it here, we just use the alpine package, which is
already included in the linuxkit/alpine base.
Can be instantiated with a service stanza such as:
- name: qemu-ga
image: "linuxkit/qemu-ga:e5fbcf55926f6e1a96b3e49a392e547e8be1022c"
binds:
- /dev/vport0p1:/dev/vport0p1
The only functionality I've tested is to report IP addresses to the host (e.g.
via `virsh domifaddr`).
The image is configured to use `/dev/vport0p1` by default. If your VM image is
using a different port number then you can either incorporate the rename into
the bind ("/dev/vport1p1:/dev/vport0p1") or override the command with:
command: ["/usr/bin/qemu-ga", "-p", "/dev/vport1p1"]
The mdev tool appears to not create the symlinks which udev would provide
`/dev/virtio-ports/org.qemu.guest_agent.0` hence the need to hardcode the
potentially unstable `/dev/vportNp1`, `N` seems to depend on the number and
order of virtio devices in use. I don't know if it is possible to get mdev to
create these links. For reference the udev rule is:
SUBSYSTEM=="virtio-ports", KERNEL=="vport*", ATTR{name}=="?*", SYMLINK+="virtio-ports/$attr{name}"
See https://wiki.libvirt.org/page/Qemu_guest_agent for more info on the guest
agent.
A suitable stanza is added to `projects/swarmd/swarmd.yml` since that is where
I am using it.

The latest version of the `moby` tool now requires that the output formats
be specified in the CLI not in the yaml file.

Since containers are spawned by containerd (which is in the host PID namespace)
and not in the swarmd container's namespace.

The sha1 tag should be sufficient to uniquely identify the image
and the sha256 versions are just very long...

This is needed for cloud environments that want to get their metadata in
the onboot phase over the network.

A few YAML files include the binfmt container, where it's not really
needed. Remove it to make the samples simpler.

As suggested by @shykes these are clearer
- onboot for things that are run at boot time to completion
- services for persistent services

It is not necessary to bring up `eth0`, the program does it fine.
This means we can remove shell script, clean up build.

In #1485 I was still using a local mobylinux/init containing #1436, even though
I had included the necessary files in the swarmd container.
Switch to the current standard init package and drop the unnecessary bind.
Also `git add .gitignore` which I forgot last time too.

This is based on https://github.com/docker/swarmkit/pull/1965 which adds a
direct containerd executor to swarmkit. It is very much a work in progress.
With a suitable moby image (such as projects/swarmd/swarmd.yml) something like
this should work:
runc exec swarmd swarmctl service create --image docker.io/library/nginx:alpine --name nginx
runc exec swarmd swarmctl service ls
