In ansible we are trying to access different templates based on variable.
We have following template files like:
templates
taks
In tasks we need to copy template file based on the app name. for eg: we will specify a variable named "instance_name" to either app1 or app2 or app3.
Now based on the variable we need to copy the app file to /opt/(( instance_name }}/conf.d/.
we created ansbile task as follows but its not working.
- name: 'Copy {{ instance_name }} file to /opt/conf.d/ Directory'
template:
src: "{{ instance_name }}"
dest: "/opt/{{ instance_name }}/conf.d/"
owner: root
group: root
mode: 0644
When we hard code "src" to app1.conf.j2 its working for app1.
We have following template files like:
templates
app1.conf.j2
app2.conf.j2
app3.conf.j2
app2.conf.j2
app3.conf.j2
taks
app.yml
In tasks we need to copy template file based on the app name. for eg: we will specify a variable named "instance_name" to either app1 or app2 or app3.
Now based on the variable we need to copy the app file to /opt/(( instance_name }}/conf.d/.
we created ansbile task as follows but its not working.
- name: 'Copy {{ instance_name }} file to /opt/conf.d/ Directory'
template:
src: "{{ instance_name }}"
dest: "/opt/{{ instance_name }}/conf.d/"
owner: root
group: root
mode: 0644
When we hard code "src" to app1.conf.j2 its working for app1.
Please let us know is it possible with this method? We are having around 20 apps and whats the best method to simplify the ansible playbook to specify only the variable.
Thanks & Regards
Geo

You don't give any details how your task fails, but I would guess you need to say:

Thanks Racke.
Sorry it was my typo. Pls see my app.yml:
- name: 'Copy {{ instance_name }} file to /opt/conf.d/ Directory'
template:
template:
src: "{{ instance_name }}.conf.j2"

owner: root
group: root
mode: 0644
In defaults main.yml defined vaiable as
instance_name: 'app1'
Please see the error I am getting:

Where is your template located? It needs to be on the Ansible controller.

Yes template located on controller itself. We can it's getting the name "app1".
For template src only its getting error.
Pls see variable instance_name
got it's value as app1 in the result. Issue is only with src:
TASK [test : Copy app1 file to /opt/conf.d/ Directory

What is the exact file name of the app1 template ? Also why don't you use copy: instead of template: ?
