blockinfile – Insert/update/remove a text block surrounded by marker lines¶
Synopsis¶
This module will insert/update/remove a block of multi-line text surrounded by customizable marker lines.
Parameters¶
Notes¶
Note
This module supports check mode.
When using ‘with_*’ loops be aware that if you do not set a unique mark the block will be overwritten on each iteration.
As of Ansible 2.3, the dest option has been changed to path as default, but dest still works as well.
Option follow has been removed in Ansible 2.5, because this module modifies the contents of the file so follow=no doesn’t make sense.
When more then one block should be handled in one file you must change the marker per task.
Examples¶
# Before Ansible 2.3, option 'dest' or 'name' was used instead of 'path'
- name: Insert/Update "Match User" configuration block in /etc/ssh/sshd_config
blockinfile:
path: /etc/ssh/sshd_config
block: |
Match User ansible-agent
PasswordAuthentication no
- name: Insert/Update eth0 configuration stanza in /etc/network/interfaces
(it might be better to copy files into /etc/network/interfaces.d/)
blockinfile:
path: /etc/network/interfaces
block: |
iface eth0 inet static
address 192.0.2.23
netmask 255.255.255.0
- name: Insert/Update configuration using a local file and validate it
blockinfile:
block: "{{ lookup('file', './local/sshd_config') }}"
dest: /etc/ssh/sshd_config
backup: yes
validate: /usr/sbin/sshd -T -f %s
- name: Insert/Update HTML surrounded by custom markers after <body> line
blockinfile:
path: /var/www/html/index.html
marker: "<!-- {mark} ANSIBLE MANAGED BLOCK -->"
insertafter: "<body>"
block: |
<h1>Welcome to {{ ansible_hostname }}</h1>
<p>Last updated on {{ ansible_date_time.iso8601 }}</p>
- name: Remove HTML as well as surrounding markers
blockinfile:
path: /var/www/html/index.html
marker: "<!-- {mark} ANSIBLE MANAGED BLOCK -->"
block: ""
- name: Add mappings to /etc/hosts
blockinfile:
path: /etc/hosts
block: |
{{ item.ip }} {{ item.name }}
marker: "# {mark} ANSIBLE MANAGED BLOCK {{ item.name }}"
loop:
- { name: host1, ip: 10.10.1.10 }
- { name: host2, ip: 10.10.1.11 }
- { name: host3, ip: 10.10.1.12 }
