          package:
            state: present # required. Whether to install (C(present)), or remove (C(absent)) a package. Other states depend on the underlying package module, i.e C(latest).
            name: influxdb # required. Package name, or package specifier with version, like C(name-1.0).,Be aware that packages are not always named the same and this module will not 'translate' them per distro.

              state: started # not required. choices: reloaded;restarted;started;stopped. C(started)/C(stopped) are idempotent actions that will not run commands unless necessary.  C(restarted) will always bounce the service.  C(reloaded) will always reload. B(At least one of state and enabled are required.) Note that reloaded will start the service if it is not already started, even if your chosen init system wouldn't normally.

          firewalld:
              state: enabled # required. choices: enabled;disabled;present;absent. Enable or disable a setting. For ports: Should this port accept(enabled) or reject(disabled) connections. The states "present" and "absent" can only be used in zone level operations (i.e. when no other parameters but zone and state are set).
              permanent: yes # not required. Should this configuration be in the running firewalld configuration or persist across reboots. As of Ansible version 2.3, permanent operations can operate on firewalld configs when it's not running (requires firewalld >= 3.0.9). (NOTE: If this is false, immediate is assumed true.)d
              port: '{{ item }}/tcp' # not required. Name of a port or port range to add/remove to/from firewalld. Must be in the form PORT/PROTOCOL or PORT-PORT/PROTOCOL for port ranges.
