Lineinfile append at EOF

Hi all,

I am trying to use the lineinfile module to append some of the software details to a file.
I don’t want to match to any regexp, but just insert every software details at the EOF.

Below is the piece of code.

  • name: Collect python details
    action: get_python_details
    register: python

  • name: Write registered variable to file
    local_action: lineinfile dest={{ third_party_dest_path }} line={{ python }} regexp=“” insertafter=EOF state=present create=yes

Have also tried giving regexp=“^$”, regexp=“^\s*$” as well to match to an empty line, but throws the below error.

Error:

An exception occurred during task execution. The full traceback is:
Traceback (most recent call last):
  File "/root/.ansible/tmp/ansible-tmp-1465888759.41-82910653497853/lineinfile", line 2540, in <module>

    lines.append(line + os.linesep)

fatal: [172.19.3.60 -> localhost]: FAILED! => {"changed": false, "failed": true, "invocation": {"module_name": "lineinfile"}, "parsed": false}




Kindly help on how to go about appending to EOF without matching to any regexp.



Thanks in advance,

Hi All,

I figured out that the below works to append to a file,

  • name: Write redis details to file
    local_action: lineinfile dest={{ third_party_dest_path }} line=redis state=present create=yes

However, i am unable to append the registered variable value to the file

  • name: Write redis details to file
    local_action: lineinfile dest={{ third_party_dest_path }} line=“{{ redis }}” state=present create=yes

Mona, I don’t think you need the regexp parameter, just set ‘insertafter: EOF’ to get it to append at the end of the file. See for what works for me in one of my scripts:

  • name: add script exec to bashrc
    lineinfile:
    dest: /home/.bashrc
    state: present
    line: ‘. /home/.profile-custom’
    insertafter: EOF

You should probably try using {{ redis.stdout }}. Registered variables are not inherently strings, unlike extra_vars.
