docker_network

The docker_network resource is responsible for managing Docker named networks. Usage of overlay driver requires the docker_service to be configured to use a distributed key/value store like etcd, consul, or zookeeper.

Actions

• :create - create a network
• :delete - delete a network
• :connect - connect a container to a network
• :disconnect - disconnect a container from a network

Properties

• aux_address - Auxiliary addresses for the network. Ex: ['a=192.168.1.5', 'b=192.168.1.6']
• container - Container-id/name to be connected/disconnected to/from the network. Used only by :connect and :disconnect actions
• driver - The network driver to use. Defaults to bridge, other options include overlay.
• enable_ipv6 - Enable IPv6 on the network. Ex: true
• gateway - Specify the gateway(s) for the network. Ex: 192.168.0.1
• ip_range - Specify a range of IPs to allocate for containers. Ex: 192.168.1.0/24
• subnet - Specify the subnet(s) for the network. Ex: 192.168.0.0/16

Examples

Create a network and use it in a container

docker_network 'network_g' do
  driver 'overlay'
  subnet ['192.168.0.0/16', '192.170.0.0/16']
  gateway ['192.168.0.100', '192.170.0.100']
  ip_range '192.168.1.0/24'
  aux_address ['a=192.168.1.5', 'b=192.168.1.6', 'a=192.170.1.5', 'b=192.170.1.6']
end
 
docker_container 'echo-base' do
  repo 'alpine'
  tag '3.1'
  command 'nc -ll -p 1337 -e /bin/cat'
  port '1337'
  network_mode 'network_g'
  action :run
end

Connect to multiple networks

docker_network 'network_h1' do
  action :create
end
 
docker_network 'network_h2' do
  action :create
end
 
docker_container 'echo-base-networks_h' do
  repo 'alpine'
  tag '3.1'
  command 'nc -ll -p 1337 -e /bin/cat'
  port '1337'
  network_mode 'network_h1'
  action :run
end
 
docker_network 'network_h2' do
  container 'echo-base-networks_h'
  action :connect
end

IPv6 enabled network

docker_network 'network_i1' do
  enable_ipv6 true
  subnet 'fd00:dead:beef::/48'
  action :create
end
