Martynas Pumputis 2a12053122 Do not skip bridge initialization if such exists
EnsureBridge used to skip creation and initialization of the weave
bridge and friends if such existed. This caused problems when
EnsureBridge failed before completing all init steps and so, subsequent
weaver could not work without "weave reset".

This change makes EnsureBridge idempotent.

Martynas Pumputis ade6738789 Handle "weave expose" in weaver
The change makes "weave expose" to call the "/expose" HTTP
endpoint implemented in router which exposes the bridge.

Such architectural change required as we need to know whether NPC is
enabled when exposing the bridge and weaver knows this fact the best.

Unfortunately, this change makes impossible to "weave expose"
when weaver is not running.

Bryan Boreham 9a90898c7d Merge branch 1.9 2017-05-05 20:54:46 +01:00
Martynas Pumputis 2ebd358aeb Workaround missing docker.sock in plugin-v2
"docker.sock" is used to access Docker API which is required to:

1. subscribe to Docker events to configure-arp,
2. query Docker network info to detect whether multicast should be
   enabled.
3. get list of Swarm peers before starting the plugin.

(1) is currently not implemented.

(2) is replaced by WEAVE_MULTICAST env var which
can enable multicast for all Weave networks created by
the plugin (not ideal, but better than nothing).

(3) is fixed by not removing "restart.sentinel".

Marc CARRE be11db45d8 Ignore error when deleting a container's interface.
Fixes #2921, as all errors are now ignored, including `ENOENT`.
This command typically attempts to delete the network interface `eth0` of a container being destroyed by Kubernetes.
If this interface has already been destroyed or is missing for whatever reason, we still want to remove this container's entry from IPAM in order to free associated resources.

Martynas Pumputis cfe26ae346 Add an ugly way to match whether network is ours to plugin
Docker Plugin V2 does not expose a plugin name to the plugin, so we
check for "net-plugin" within driver name of a network to detect
whether network is ours.

Martynas Pumputis 01bfa602ad Pass noDNS and isPluginV2 flags to plugin
- "noDNS" controls whether upon ContainerStarted event a container
  should be registered within the Weave DNS.
- "isPluginV2" will be used to determine a path to host's /proc.

Martynas Pumputis d3d2de5f1f Make NetworkAllocate to return original options
NetworkAllocate is called on Swarm master node which creates a network.
The return option map is used to describe the network, and is passed
to CreateNetwork  which is called on all nodes when a service is
created.

Returning nil instead the actual options made Docker to omit
the "works.weave.multicast" flag, thus no multicast could be used
in Swarm.
