Every user on kuber have free subdomain as
myapp.kuber.host, subdomain name is same as kubernetes namespace for your account.
You may also add custom domains for free, as much as you need.
To add custom domain, register it in domains page (for security reasons), and make DNS settings:
ALIASDNS record to your namespace domain e.g.
ADNS record to
CNAMEDNS record to to your namespace domain e.g.
myapp.kuber.host(only for subdomains)
HTTPS with Let's Encrypt
It's always better to use HTTPS so your internet provide won't spy on you. Kuber can generate free HTTPS certificate automatically for domains as
and custom domains (via Let's Encrypt). To enable it - add annotaion
certmanager.k8s.io/cluster-issuer: letsencrypt and section
tls in your ingress (see example bellow).
Few minutes after you create create or update ingress - it will be ready to use
Ingress is kubernetes object to manage external access for running services. In provides load balancing, SSL, custom headers, http authentication, access control, etc. You may have multiple ingress object to expose different services or to utilize multiple domains.

Generated HTTPS certificate will be stored in kubernetes secret, secret's name is set via
