metallb

We have hosted the application metallb in order to run this application in our online workstations with Wine or directly.

Quick description about metallb:

MetalLB is a load-balancer implementation for bare metal Kubernetes clusters, using standard routing protocols. Kubernetes does not offer an implementation of network load balancers (Services of type LoadBalancer) for bare-metal clusters. The implementations of network load balancers that Kubernetes does ship with are all glue code that calls out to various IaaS platforms (GCP, AWS, Azure�). If you�re not running on a supported IaaS platform (GCP, AWS, Azure�), LoadBalancers will remain in the �pending� state indefinitely when created. Bare-metal cluster operators are left with two lesser tools to bring user traffic into their clusters, �NodePort� and �externalIPs� services. Both of these options have significant downsides for production use, which makes bare-metal clusters second-class citizens in the Kubernetes ecosystem. MetalLB aims to redress this imbalance by offering a network load balancer implementation that integrates with standard network equipment.

Features:

• Previous versions of MetalLB are configurable via a configmap
• MetalLB implements a FRR Mode that uses an FRR container as the backend for handling BGP sessions
• Requires some IPv4 addresses for MetalLB to hand out
• When using the BGP operating mode, you will need one or more routers capable of speaking BGP
• When using the L2 operating mode, traffic on port 7946 (TCP & UDP, other port can be configured) must be allowed between nodes, as required by memberlist
• Documentation available

Programming Language: Go.
