Hi,

for this to work artifacturl always needs to be a list. A first attempt could look like this:

Is it possible to set_fact in a loop store the constructed variable in a list and pass it to *get_url* method .

- include_vars:
file: vars.yml
- set_fact:
b_url: http://{{item}}/sr/pr/
# jar is a list in vars.yml
loop: "{{ jars }}"
register: b_url
- debug:
msg: "no of sites are ==> {{ b_url }} "
- name: Container Checks
block:
- name: download "{{file }}"
get_url:
url: "{{ item }}"
dest: "/manual/jar/"
loop: {{b_url}}

Hello Manoj,

1) Using register in a set_fact task doesn't make sense, as set_fact is supposed to set the
   variables.

2) Do you really need to use set_fact?

  - name: download "{{file }}"
    get_url:
      url: "http://{{item}}/sr/pr/"
      dest: "/manual/jar/"
    loop: "{{ jars }}"

    Hi,

    for this to work artifacturl always needs to be a list. A first attempt could look like this:

    *---*
    *- name: Block to Deploy on Servers*
    * block:*
    * - set_fact:*
    * artifact_url: "https://my.url/>"\*
    * - set_fact:*
    *
    *
    * group_id: "{% if app_name == 'group1' %}/com/connectors/{% elif app_name == 'group2' %}*
    * /com/connectors/{%

else %}/com/services/{% endif %}"*

    * register: group_id *
    * *
    * - set_fact:*
    * artifacturls: *
    * - "{ artifact_url }}{{ group_id }}jar1/{{ app_version }}/{{ item }}-{{ app_version }}.jar"*
    * **- "{ artifact_url

}}{{ group_id }}jar2/{{ app_version }}/{{ item }}-{{ app_version }}.jar"*

    * when: app_name == group2*
    * *
    **
    * - set_fact:*
    * artifacturls: *
    * - "{ artifact_url }}{{ group_id }}{{ app_name }}/{{ app_version }}/{{ app_name }}-{{ app_version }}.jar"*
    * when: app_name != group2*

    /pass the constructed variable to another block /

    *- name: Block to get file "{{app_name}}"*
    * block:*
    * - name: download "{{app_name}}" form url*
    * get_url:*
    * url: "{{ item }}"*
    * dest: "/manual/{{ app_name }}.jar"*
    * loop:*
    * - {{ artifacturls }}*

    This leads to a bit of duplication for group2 which could be omitted by a more complex construct like this:

    * - set_fact:*
    * artifacturls: "({{ artifact_urls | default()) + {{ artifact_url }}{{ group_id }}{{ item }}/{{
    app_version }}/{{ item }}-{{ app_version }}.jar"*
    * when: app_name == group2*
    * loop:*
    * - jar1*
    * - jar2 *
    *
    *

    Hope that helps,*
    *
