netctl

Role for deploy profiles for systemd-based network-manager netctl.

Requirements for usage

  • Ansible 2.5+;

Link types supported

  • ethernet (inc. pseudo, like IMQ);
  • vlan (802.1q);
  • pppoe;
  • mobile_ppp (USB modem support);
  • tunnel (ipip, gre, etc);
  • bonding;
  • bridge;

Extra

  • ip addresses, before deploy will be checked by Jinja with python-netaddr lib;
  • Support 'static' and 'dhcp' connections;
  • Support arrays of addresses, DNS;
  • DHCP client can be reassigned and accept options;
  • Any ip commands can be executed with profile;
  • Support for link options (run ip link add type bond help to see the available options);
  • Support PostUp and PreDown command execution;

Example configuration

---
netctl_restart: 'false'
netctl_enable: 'false'
netctl_drop_exists_interfaces: 'true'
netctl_drop_exists_hooks: 'true'
netctl_deploy_interfaces: 'true'
netctl_deploy_interface_hooks: 'true'
netctl_deploy_global_hooks: 'true'

# Whenever a profile is read, all executable scripts in '/etc/netctl/hooks' and any
# executable script in '/etc/netctl/interfaces' with the name of the interface for
# the profile are sourced. Declarations in an interface script override declarations
# in a profile, which override declarations in hooks.
netctl_hooks:
- name: 'hook1'
  action:
  - 'echo 1 > /proc/net/super'
  - 'echo 2 > /proc/net/super'

netctl_interfaces:
# Interface name
- interface: 'lag0'
# A description of the profile.
  description: 'Bonded interface'
# The connection type used by the profile. Available connection types:
#
# ethernet - For wired connections.
# bond - For bonded interfaces.
# bridge - For bridge interfaces.
# pppoe - For PPPoE connections.
# mobile_ppp - For mobile broadband PPP connections that use a USB modem.
# tunnel - For tunnel interfaces.
# tuntap - For TUN/TAP interfaces.
# vlan - For VLANs on ethernet-like connections.
  connection: 'bond'
# Bonding slaves, one or more devices.
  physdev:
  - 'eth0'
  - 'eth1'
# One of 'static' or 'dhcp'.
  ip: 'static'
# One nameserver or list of nameservers.
  dns: '127.0.0.1'
# Whether or not the absence of a carrier (plugged-in cable) is acceptable.
# Defaults to 'no'.
  skip_no_carrier: 'yes'
# Set to 'yes' to force connecting even if the interface is up. Do not use this
# unless you know what you are doing.
  force_connect: 'yes'
# Maximum time, in seconds, to wait for an interface to get up. Defaults to '5'.
  timeout_up: '5'
# Set to 'yes' to consider the profile activated only when it is online.
  wait_online: 'no'
# Additional options to be passed to ip link. Run `ip link add type bond help`
# to see the available options.
  link_options:
  - 'mode 4'
  - 'xmit_hash_policy 2'
  - 'lacp_rate 1'
  - 'miimon 100'
# A command that is executed after a connection is established. If the specified
# command returns anything other than 0 (success), netctl will abort and stop
# the profile. If the command should be allowed to fail, add '|| true' to the
# end of it.
  ifup_local:
  - 'ethtool -K eth0 tso off'
  - 'ethtool -K eth1 tso off'
# A command that is executed before a connection is brought down. Similar precautions
# should be taken as with 'ifup_local'.
  ifdown_local:
  - 'ethtool -K eth0 tso on'
  - 'ethtool -K eth1 tso on'
# An list to pass to ip. This can be used to achieve complicated configurations
# within the framework of netctl.
