docknet: Distribution system for docker containers
A container distribution system for docker containers (based on docker, etcd and pipework)
Each host has an
etcd daemon running. This provides access to a shared configuration among the hosts. The configuration consists of two data sets:
Containers - for each container to be present in the overall system, a set of properties are defined.
Map - the map defines for each container the host it is assigned to.
docknet is implemented by a few simple scripts:
docknet-etcd- used for starting the
etcddaemon on each host. The supplied script is just an example. See
etcddocumentation for more details.
docknet-bridge- used for setting up the
docknetnetwork on each host. It creates a bridge device (
docknet0) and then binds the physical network device to the bridge.
docknet-scan- scans the configuration (
maps) and determines which containers should execute on the current host. These containers are then created/started and assigned the IP address as given by the configuration.
The following software needs to be installed on each host in the
Currently no tool is available for editing the
etcd key/value pairs. Use
etcdctl to create and update your configuration.
