HTTPS ingress configuration
HTTPS ingress is controlled by the server holmium and forwarded to the configured servers.
To set up a new HTTPS vhost, the following steps need to be taken:
- Select a domain (for internal services we use sub-domains of
.n39.eu). - Create an external CNAME from this domain to
dyndns.n39.eu. - Create an internal DNS entry in the Descartes DNS config. This is usually an alias on an existing server.
- Add the entry to the holmium playbook.
- Set up Dehydrated and vhost on the target host, e.g. using
setup_http_site_proxy.
Do not forget to execute all playbooks with relevant changes.
