HELB (Homemade External Load-Balancer) does what you would normally see in cloud providers (AWS ELB EKS or ALIYUN SLB CSK)

• Load balance traffic across nodes (why?)
• Resolve sub-domain DNS for services
• Assign custom domain names to services, access services without memorizing ip and ports.

Working on better examples see install for deployment into kubernetes cluster

Because kubernetes pods requires port usage declaration upon creation, you port usages in services (see below) are limited to what you specified when you started up HELB

If you want unlimited access, try clone the repo and run go -o helb build cli/balance to build your own copy for bare-metal deployment.
