Ansible readfile and concatenate a variable to each line

[Manoj Chander]

Hi I have a file with list of filenames .I want to read each line and add a variable {{version}} to the end and pass it to another task which will download the artifact 

MY_File

cat file/branches.txt mhr- mtr- tsr

I want to get each line add {{version}} to it

mhr-1.1-SNAPSHOT mtr-1.1-SNAPSHOT tsr-1.1-SNAPSHOT

I couldn't get the file names and append them. below is a failed attempt by me.

---

- name: get file names

  shell: echo {{item}}{{version}}

  register: result

  with_lines: cat files/branches.txt

- include_tasks: 2main.yml

  with_items: "{{result.results}}"

The task below does the job

- debug:
msg: "{{ lookup('file',
'files/branches.txt').split()|
product([version])|
map('join')|
join(' ') }}"

gives

msg: mhr-1.1-SNAPSHOT mtr-1.1-SNAPSHOT tsr-1.1-SNAPSHOT

In addition to this, you've said "each line add {{version}} to it".
If there are more lines, e.g.

cat files/branches.txt
mhr- mtr- tsr-
xhr- xtr- xsr-
yhr- ytr- ysr-

the task below iterates the lines

- debug:
msg: "{{ item.split()|

product([version])|
map('join')|
join(' ') }}"

loop: "{{ lookup('file',
'files/branches.txt').splitlines() }}"

gives

msg: mhr-1.1-SNAPSHOT mtr-1.1-SNAPSHOT tsr-1.1-SNAPSHOT

msg: xhr-1.1-SNAPSHOT xtr-1.1-SNAPSHOT xsr-1.1-SNAPSHOT
msg: yhr-1.1-SNAPSHOT ytr-1.1-SNAPSHOT ysr-1.1-SNAPSHOT

 not able to achieve desired result.

- include_vars:

    file: releasevars.yml
  when: env == "dev"
 
- slurp:
    src: '{{item}}'
  register: input_file_content
  loop:
    - "{{file}}"
  delegate_to: localhost

- debug:
    msg: "{{ item['content'] | b64decode }}"
  loop: '{{ input_file_content["results"] }}'
- set_fact:
      files_version: "{{ (input_file_content['content'] | b64decode).split('\n') | map('regex_replace', '^(.+)$', '\\g<1>' + version ) }}"

- name: Download artifact
  maven_artifact:
      group_id: com.devops.services

Try this

- set_fact:
files: "{{ lookup('file','releasevars.yml').split()|

product([version])|
map('join')|

list }}"

- slurp:
src: "{{ item }}"
register: input_file_content

loop: "{{ files }}"
