You declare a configuration state. If the machine is in that state, Ansible
makes no change.
Don't check if the package has been downloaded. Let Ansible worry about that.
It is fair to worry about whether the download folder exists. For that you only
need to name the folder in the file task.
file:
path: /home/pvs/Build/data
state: directory
mode: 0755
register: file_stat
Is /home/pvs/Build/data a local folder on the control host where you run
Ansible, or on each remote machine?

Thank you for the help.
sorry I had corrected the yum download portion (see below), but did not update
here. the below solves the download only part.
I need to be able to download it to a directory as I am not always going to be
online to access repositories. I will be online at one point to get the files,
but in the future may not as I switch between builds. I just do not know how to
structure the when statement for downloading only when the file is not there.
- name: Download RPMs
yum:
name: "{{ rpms }}"
state: present
enablerepo: "*"
download_dir: /home/pvs/Build/data/
download_only: true
when: file_stat.stat.exists == False

Have you looked at the module docs? They show you what "results" is supposed to
look like. If I may I'd like to suggest a slightly different approach. The
Ansible philosophy is for each task to declare a state and let Ansible ensure
the machine is in that state when it is done with the task.
Let's break your problem down into three states:
1. a local directory needs to exist
2. RPMs need to be in that local directory
3. RPMs in that local directory need to be installed
Given those three states you have three tasks:
- name: make sure /home/pvs/Build/data exists
file:
path: /home/pvs/Build/data
state: directory
mode: 0755
The task above looks fine. It accomplishes state #1 in a single task.
- name: Make sure RPMs are in /home/pvs/Build/data
yum:
name: "{{ item }}"
state: present
enablerepo: "*"
dest: /home/pvs/Build/data/
with_items: "{{ rpms }}"
The task above doesn't look great. I am not convinced it will download the
packages to /home/pvs/Build/data. The yum module does not have a "dest"
parameter. It has a download_dir parameter. The download_dir parameter is only
effective when used in conjunction with download_only. The next question I have
is why do you want these packages downloaded to an alternate local directory?
Are they in a repo you have enabled? If so why download them vs simply
installing them FROM THAT REPO? This would let you accomplish states 2 and 3 in
a single step and eliminate state 1 entirely.
- name: RPMs are installed from /home/pvs/Build/data
yum:
name: /home/pvs/Build/data/{{ item }} .x86_64.rpm
state: present
installroot: /home/pvs/Build/data
enablerepo: "*"
allowdowngrade: yes
with_items: "{{ rpms }}"
register: yum_result
Given what I wrote about task / state 2 it seems task 3 may be unnecessary.

This Ansible script loads the list of RPMs to download from a separate file
called "rpms.yml" using the vars_files directive. This file should be in the
same directory as the playbook and should be in YAML format.
The file should contain a list of RPMs names like this:
rpms:
- file1
- file2
- file3
Background on my script:
This Ansible script first uses the yum command to download the RPMs to a local
directory, it will also check if the file already exists in the directory
before downloading it, if it already exists it will skip the downloading task.
Once all the files are downloaded, it will use the yum command again to install
the RPMs from the local directory.
Please make sure to provide the correct path to the directory where you want to
store the RPMs, and the correct file names in the rpms.yml file.
any help would be appreciated.
Thank you
