Before the advent of `ansible-vault`, and long before `certbot`/`lego`,
I used to keep certificate files (and especially private key files) out
of the Git repository. Now that certificates are stored in a separate
repository, and only symlinks are stored in the configuration policy,
this no longer makes any sense. In particular, it prevents the continuous
enforcement process from installing Let's Encrypt certificates that have
been automatically renewed.
If another role that depends on the *apache* role accidentally creates
an invalid configuration, it will be impossible to correct it by
subsequent invocations of its playbook. This is because the *apache*
role always tries to start the service, which will fail if the
configuration is invalid, thus aborting the playbook. With this early
abort, there is no way for later tasks to correct the error.
Playbooks that include the *apache* role should have a task that is
executed after all the roles have been applied to ensure the service is
running.
The *apache* role installs and configures the Apache HTTPD server and
its *mod_ssl* module. It currently only works on Fedora/RHEL-based
distributions.
