<p>Is possible to add authentication adding additional annotations in the Ingress rule. The source of the authentication is a secret that contains usernames and passwords inside the key <code class="codehilite">auth</code>.</p>

The other possible values for <code class="codehilite">nginx.ingress.kubernetes.io/lua-resty-waf</code> are <code class="codehilite">inactive</code> and <code class="codehilite">simulate</code>.
In <code class="codehilite">inactive</code> mode WAF won't do anything, whereas in <code class="codehilite">simulate</code> mode it will log a warning message if there's a matching WAF rule for given request. This is useful to debug a rule and eliminate possible false positives before fully deploying it.</p>
<p><code class="codehilite">lua-resty-waf</code> comes with predefined set of rules <a href="https://github.com/p0pr0ck5/lua-resty-waf/tree/84b4f40362500dd0cb98b9e71b5875cb1a40f1ad/rules">https://github.com/p0pr0ck5/lua-resty-waf/tree/84b4f40362500dd0cb98b9e71b5875cb1a40f1ad/rules</a> that covers ModSecurity CRS.
You can use <code class="codehilite">nginx.ingress.kubernetes.io/lua-resty-waf-ignore-rulesets</code> to ignore a subset of those rulesets. For an example:</p>
