I have tried the above one getting below error message
ERROR! 'apt' is not a valid attribute for a Play
The error appears to be in '/projects/challenge/fresco_nginx/tasks/main.yml': line 3, column 3, but may
be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
#installing nginx and postgresql
- name: Install nginx
^ here

Answer 4

All the answers give above works on installing nginx, the problem is nginx is running port 80 and the score script check 9090. If you curl using port 80 you will get response. So you need to find some way to change the nginx conf file to use port 9090.

Answer 5

Below code worked for me:
Define your port number and the site you wish to redirect nginx server to in .j2 file in Templates folder under your roles.
Include a task in Playbook to set the template to /etc/nginx/sites-enabled/default folder. Include a notify for the handler defined in
'Handlers' folder.
In some cases if nginx server doesnt restart, use 'sudo service nginx restart' at the terminal before testing your code.
Ansible-Sibelius (Try it Out- Write a Playbook)

- name: Start PostgreSQL
service:

state: started
- name: Set the configuration for the template file
template:
src: /<path-to-your-roles>/templates/sites-enabled.j2
dest: /etc/nginx/sites-enabled/default
notify: restart nginx
