Hello,
I did not know the set_fact plugin it is worth investigating thanks.
Here are 2 other options :
(1) concatenate via echo
- hosts: localhost
gather_facts: no
tasks:
- name: initialize nginx build options
command: echo "./configure"
register: nginx_build_options
- name: nginx_spdy option
command: echo "{{ nginx_build_options.stdout ~ '
--with-http_spdy_module'}}"
register: nginx_build_options
when: nginx_spdy
- name: nginx_upload_progress option
command: echo "{{ nginx_build_options.stdout ~ '
--add-module=/var/opt/nginx-upload-progress-module/'}}"
register: nginx_build_options
when: nginx_upload_progress
- name: output
debug: var=nginx_build_options
beware: this will make a lot of ssh round trips i guess i you have tons of
options. maybe using local_action: could help here.
(2) template: and command:
use the template: module to send to the remote a templated build script.
in this template, you will be able to hide all the complexity of the
configure options without making a long list of nearly useless tasks + you
will send a lot less ssh commands
then execute your script with the command: module
Hope this helps
Jerome
