Final comments

• The script generate-ejabberd-yaml.sh may be used to create manifests for various environments.
• An AWS NLB will be created by the chart and a DNS record should be created to access the NLB - may be removed if not necessary.
• The annotations in statefulset will provide metrics for Prometheus and preparation for logging in Elasticsearch.
• Config secrets/ejabberd.yml and secrets/.erlang.cookie should be stored encrypted and be decrypted at manifest generation time.
• Istio template included for ejabberd GUI - may be removed if not necessary.
• AWS EFS included for document uploads - may be removed if not necessary.
