* The process to install modules has changed. You will now have to use a list variable, `nginx_modules`, instead of manually setting the modules you want to install to `true` or `false`. This change will also simplify adding future supported modules to this role. You can find a list of supported modules for NGINX and NGINX Plus in [`vars/main.yml`](https://github.com/nginxinc/ansible-role-nginx/blob/main/vars/main.yml).
* Modules can no longer be added to your NGINX config using this role. Please use the [`nginx_config`](https://github.com/nginxinc/ansible-role-nginx-config) role instead.
* Changed `nginx_configure` default value from `true` to `false` to further promote the adoption of the [NGINX config](https://github.com/nginxinc/ansible-role-nginx-config) role.
*`nginx_setup_license` -- Determine whether you want to use this role to upload your NGINX license to your target host.
* The role will now fail automatically if you try to deploy NGINX from an official repository in an unsupported distribution. You can find a list of supported distributions for NGINX and NGINX Plus in [`vars/main.yml`](https://github.com/nginxinc/ansible-role-nginx/blob/main/vars/main.yml)
* Three new tags have been introduced -- `nginx_setup_license`, `nginx_install` and `nginx_check_support`.
* Add Alpine 3.12 to the list of supported platforms.
* Remove Alpine 3.8 from the list of supported platforms.
* The Debian and Ubuntu repositories have slightly changed. You may run into some duplication issues when running the role on a preexisting target that already has had NGINX installed using the role. To fix this, manually remove the old repository source.
ENHANCEMENTS:
* Update Ansible to `2.9.12` and Ansible Lint to `4.3.2`.
* Explicitly define `mode` in relevant tasks.
* Explicitly define the `nginx``apt_repository` filename in Debian based distros.
FEATURES:
* TravisCI now always uses the latest version of Docker.
BUG FIXES:
* Building OpenSSL from source should now work properly in CentOS 8.
With the advent of Ansible collections and to reduce the overhead of this role, the decision has been made to split this role into three smaller roles:
* The NGINX Ansible role will keep working as is and be used to install and setup NGINX.
* There now is a separate role to manage and create NGINX configurations available [here](https://github.com/nginxinc/ansible-role-nginx-config). Any new issues or PRs related to configuring NGINX should be submitted in the new NGINX Config repository. New issues or PRs related to configuring NGINX submitted in this repository will not be worked on. The NGINX configuration functionalities included in this role will be removed in an upcoming release.
* NGINX Unit now has a separate role available [here](https://github.com/nginxinc/ansible-role-nginx-unit). Any new issues or PRs related to NGINX Unit should be submitted in the new NGINX Unit repository. New issues or PRs related to NGINX Unit submitted in this repository will not be worked on. The NGINX Unit functionalities included in this role will be removed in an upcoming release.
* The Debian and Ubuntu repositories have slightly changed. You may run into some duplication issues when running the role on a preexisting target that already has had NGINX installed using the role. To fix this, manually remove the old repository source.
* If you use `custom_options` you will now need to manually end each directive with a semicolon.
* The listen directive structure in the `stream` template has been updated to the listen directive structure found in the `http` template. You can now specify multiple `listen` directives in the same `server` block as well as include any extra `listen` options you might need.
Old configuration example
```yaml
listen_address: localhost
listen_port: 80
udp_enable: false
```
New configuration example
```yaml
listen:
listen_localhost:
ip: 0.0.0.0 # Wrap in square brackets for IPv6 addresses
port: 80
ssl: false
opts: [] # Listen opts like udp which will be added (ssl is automatically added if you specify 'ssl:').
```
The one major change is that instead of using `udp_enable: true` you will now need to use `opts: [udp]` if you wish to enable `udp`.
* Two new variables have been introduced -- `nginx_install` and `nginx_configure` -- to let you choose whether you want to install NGINX, configure NGINX, or both.
* Improve configuration cleanup capabilities. You can now remove all `*.conf` files in a given directory, or specify a list of files you wish to delete.
This is a relatively minor release, but it includes a potential breaking change (hence the version bump). The one major new feature is the ability to install/build NGINX Open Source from source.
* The new listen templating options are not backwards with the previous listen templating options. Check the `README` or `molecule/template_module/playbook.yml` for examples on how to use the new listen template.
* BSD and Linux NGINX installation tasks have undergone some major changes. As such, you may have to update your playbooks accordingly.
* When deleting your NGINX Plus license from the system, the NGINX Plus repository will also be deleted to prevent issues further down the line if you run a repository update since there will not be a license anymore to authenticate into the NGINX Plus repository.
* Role should now work correctly in distros with old versions of Python.
* Rest API configuration will now only be created when rest_api_enable is set to true (an empty file would be created in previous versions if rest_api_enable was set to false).
* Uploading/dynamically generating files should now result in the files being uploaded/created to/in the correct directory.
