Inserting an entire block of configuration using lineinfile

[Michael Baydoun]

I need to insert many lines of configuration and must use lineinfile or something similar.

The particular application in question also writes changes over time to other parts of the same file.

What is the best, cleanest way to accomplish this?

Is there a solution other than to string a bunch of lineinfile modules together?

You can try to loop using with_items: and storing the regexs, lines, etc in variables.

Yep, +1 to this.

For editing /etc/network/interfaces I use replace module with some patches.

- name: setup docker0 bridge

  replace:

    dest: /etc/network/interfaces

    regexp: '^(# role docker.*[\n\r]+)?iface\s+docker0\s+.*[\n\r]+([ \t]+.*[\n\r]?)*(# role docker.*[\n\r]?)?'

    replace: |

      # role docker script config BEGIN

      iface docker0 inet static

        bridge_ports    none

        bridge_stp      off

        bridge_maxwait  0

        bridge_fd       0

        address         {{ docker_net_prefix }}.255.254

        netmask         255.255.0.0

      # role docker script config END

    append: yes

  register: redocker

I have only trouble with missing trailing newline.

That regex is a brutal one.  Congrats.  I think.

This is really why I prefer the template module 99.9999999% of the time.  Ok, 100% :)
