Ansible readfile and concatenate a variable to each line - loops

Question

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}}"

Answer 1

I think what you need a new variable which contains text like mhr-1.1-SNAPSHOT depending on the source file. You can use set_fact to achieve this.
Example:
vars:
file_versions: []
version: "1.1-SNAPSHOT"
tasks:
- set_fact:
file_versions: "{{ file_versions }} + [ '{{ item }}{{ version }}' ]"
with_lines: cat file/branches.txt
- debug:
msg: "{{ item }}"
with_items: "{{ file_versions }}"
- include_tasks: 2main.yml
with_items: "{{ file_versions }}"
Gives below debug output:
TASK [debug] ************************************************************************************************************************
ok: [localhost] => (item=mhr-1.1-SNAPSHOT) => {
"msg": "mhr-1.1-SNAPSHOT"
}
ok: [localhost] => (item=mtr-1.1-SNAPSHOT) => {
"msg": "mtr-1.1-SNAPSHOT"
}
ok: [localhost] => (item=tsr-1.1-SNAPSHOT) => {
"msg": "tsr-1.1-SNAPSHOT"
}

In a nutshell:
---
- name: append version to names found in a local text file line by line
hosts: localhost
gather_facts: false
vars:
# This is the version we want to append
version: 1.1-SNAPSHOT
# This is the file on local controller containing the names
my_file: /tmp/my_file.txt
# This var will contain a list of each name in file with appended version
file_version: "{{ lookup('file', my_file).splitlines() | map('regex_replace', '^(.*)$', '\\g<1>' + version) | list }}"
tasks:
- name: Show the result
debug:
var: file_version
- name: Loop on var with an include (the passed var is item in this case)
include_tasks: some_other_tasks_working_on_item.yml
loop: "{{ file_version }}"
