how to traverse through each line of a text file in ansible - linux

Question

I have to traverse through package list file which contains list of packages with their architecture. How can I feed those input to my playbook file? I found a way to get the package names alone but architecture version is not coming. This is my package_list file
nginx | x86_64
telnet| x86_64
openssh | i386
This is my playbook
- name: get contents of package.txt
command: cat "/root/packages.txt"
register: _packages
- name: get contents of architecture from packages.txt
command: cat "/root/packages.txt" | awk '{print $3}'
register: _arch
- name: Filter
theforeman.foreman.content_view_filter:
username: "admin"
password: "mypass"
server_url: "myhost"
name: "myfilter"
organization: "COT"
content_view: "M_view"
filter_type: "rpm"
architecture: "{{ _arch }}"
package_name: "{{ item }}"
inclusion: True
loop: "{{ _packages.stdout_lines }}"
loop: "{{ _arch.stdout_lines }}"
Any help would be appreciated
The required output is package name and architecture should be read from packages.txt file through ansible-playbook

Answer 1

try this playbook:
- name: Reproduce issue
hosts: localhost
gather_facts: no
tasks:
- name: get contents of package.txt
command: cat "/root/packages.txt"
register: _packages
- debug:
msg: "package: {{ line.0 }}, arch: {{ line.1 }}"
loop: "{{ _packages.stdout_lines }}"
vars:
line: "{{ item.split('|')|list }}"
result:
ok: [localhost] => (item=nginx | x86_64) => {
"msg": "package: nginx , arch: x86_64 "
}
ok: [localhost] => (item=telnet| x86_64) => {
"msg": "package: telnet, arch: x86_64 "
}
ok: [localhost] => (item=openssh | i386) => {
"msg": "package: openssh , arch: i386 "
}
for your case:
- name: Filter
theforeman.foreman.content_view_filter:
:
:
architecture: "{{ line.1 }}"
package_name: "{{ line.0 }}"
inclusion: True
loop: "{{ _packages.stdout_lines }}"
vars:
line: "{{ item.split('|')|list }}"
following the version of ansible you could write too line: "{{ item | split('|') | list }}"

Answer 2

You need to split up the line into the necessary values by filtering.

- hosts: localhost
become: false
gather_facts: false
tasks:
- name: Gahter package list
shell:
cmd: cat package.txt
register: _packages
- name: Show packages
debug:
msg: "Name: {{ item.split('|')[0] }}, Arch: {{ item.split('|')[1] }}"
loop: "{{ _packages.stdout_lines }}"
