site name as variable about ansible-role-nginx

[jdauphant]

Hello,

Try with {{ item }}, it could work.
It could be interesting to introduce variables into the template.

Best regards,
Julien

Yeah I've tried that but does't work from the playbook, as the "{{ item }}" variable won't be defined, I'm a bit new to ansible but that's the first thing that cross my mind...

Probably the only way to achieve this is really introducing vars in the template as you suggest, might be a nice improvement to the role :)

[jdauphant]

Don't hesitate to submit a MR, unfortunately I don't have time to do that myself :(

You can also try this syntaxe also (but I think I won't work either)

    example.org: |
            listen 80;
            server_name {{ item }};

Sure, I'll poke around, I wonder if there's some way to dump/see all vars in verbose mode or something...

In alternative I guess I can use global vars and re-use them in the playbook, maybe a dictionary or something, If you don't mind can we keep this open in case I find a solution (for a while ofc)

[jdauphant]

Ok I keep it open

@jdauphant I've been looking at this again and I was wondering if there would be a way to have example.org: set to "{{site_name}}":

Say one passes a extra var ` ansible-playbook site.yml -e "site_name=example.org"

And then we have (in the site.yml playbook):

nginx_sites:
        '{{site_name}}':
          - |
            listen 80;
            server_name {{site_name}} www.{{site_name}};

            access_log  "{{nginx_log_dir}}/{{site_name}}-access.log";
            error_log   "{{nginx_log_dir}}/{{site_name}}-error.log";

Something like this would be awesome cause we can have a single playbook to spin up a bunch of nginx-sites by just passing the site_name var

But when I try to do that I get:

failed: [example.org] => (item={{site_name}}) => {"failed": true, "item": "{{site_name}}", "msg": "AnsibleUndefinedVariable: 'dict object' has no attribute u'{#site_name#}'"

I was expecting '{{site_name}}' to use the var value, but it fails with the dic object error, and I honestly don't get why, do you have any idea?

(note that this happen either with {{site_name}} or '{{site_name}}'

Guess this is the issue I'm facing --> ansible/ansible#9008 or at least similar.

My understanding is that ansible recent versions wont' do variable interpolation for "keys" cause some example seemed to indicate this worked before...

The alternative would be using set_fact I guess, but I would prefer a cleaner way, oh well

[jdauphant]

Sorry, no idea, I do not use as much Ansible

I don't think you can use a variable as a dictionary key.

You can certainly use a variable as the value for your server_name like you do in your first example but you'd have to define the variable as usual (i.e. in the playbook, or in group_vars, or wherever).

You can probably close this one?

[mike-pt]

@philipwigg yeah, you're correct and I could never really take the time to maybe find a work around.

Fell free to close

[philipwigg]

Cheers. I don't think I can close this one as it's not my issue and I'm not an owner.

[mike-pt]

lol sorry I did not realised that
