I am using ansible to update configuration file of newly added NIC for
that i have defined some variables in separate yml file
*/tmp/ip.yml*
#first interface
interface1: eth1
bootproto1: static
ipaddress1: 192.168.211.249
netmask1: 255.255.255.0
gateway: 192.168.211.2
DNS1: 192.168.211.2
#second interface
interface2: eth2
bootproto2: static
ipaddress2: 10.0.0.100
netmask2: 255.0.0.0
*Playbook*
- include_vars: /tmp/ip.yml
- name: configuring interface
lineinfile:
state=present
create=yes
dest=/etc/sysconfig/network-scripts/ifcfg-{{interface1}}
regexp="{{ item.regexp }}"
line="{{ item.line }}"
with_items:
- { regexp: '^BOOTPROTO=.*', line: 'BOOTPROTO={{interface1}}' }
- { regexp: '^IPADDR=.*', line: 'IPADDR={{ipaddress1}' }
- { regexp: '^NETMASK=.*', line: 'NETMASK={{netmask1}}' }
- { regexp: '^GATEWAY=.*', line: 'GATEWAY={{gateway}}' }
- { regexp: '^PEERDNS=.*', line: 'PEERDNS=no' }
- { regexp: '^DNS1=.*', line: 'DNS1={{DNS1}}' }
- { regexp: '^ONBOOT=.*', line: 'ONBOOT={{onboot}}' }
when: bootproto1 == 'static'
- name: configuring for DHCP
lineinfile:
state=present
create=yes
dest=/etc/sysconfig/network-scripts/ifcfg-{{interface1}}
regexp="{{ item.regexp }}"
line="{{ item.line }}"
with_items:
- { regexp: '^BOOTPROTO=.*',line: 'BOOTPROTO={{bootproto1}}' }
- {regexp: '^PEERDNS=.*',line: 'PEERDNS=yes' }
- { regexp: '^ONBOOT=.*', line: 'ONBOOT={{onboot}}' }
when: bootproto1 == 'dhcp'
//*similarly repeated for second interface*.//
Even Though this method works for 2 NIC,this is too difficult to manage
,that is for each new NIC added i need to modify playbook and update
corresponding variable in */tmp/ip.yml*.
Is there a way to add variables to /tmp/ip.yml and may be using some
separator. parse it to playbook with out modifying playbook each time a NIC
is connected.
