title: Kubernetes: Disable TLS 1.0 and 1.1 on nginx ingress
body: <p>An existing nginx ingress named <code>nginx-proxy</code> running on the K8 cluster.</p>
  <p>Now, there is a requirement from the Dev team to disable TLS 1.0, 1.1 support.</p>
  <p>Upon searching, I could see <a href="https://kubernetes.github.io/ingress-nginx/user-guide/tls/" rel="nofollow noreferrer">this solution</a> using configmap.</p>
  <p>Do you think applying/creating a new configmap as follows to an existing nginx ingress helps me to resolve the issue?</p>
  <pre><code>kind: ConfigMap
  apiVersion: v1
  metadata:
    name: nginx-proxy
  data:
    ssl-protocols: &quot;TLSv1.2 TLSv1.3&quot;
  </code></pre>
  <p>Adding a new configmap like that to an existing nginx ingress breaks anything?. Because this is for the production website.</p>
  <p>A piece of advice would be really helpful.</p>
