For other protocols check MetalLB [configuration docs]. With Docker on Linux, you can send traffic directly to the loadbalancer's external IP if the IP space is within the docker IP space. On macOS and Windows, docker does not expose the docker network to the host. Because of this limitation, containers (including kind nodes) are only reachable from the host via port-forwards, however other containers/pods can reach other things running in docker including loadbalancers. You may want to check out the [Ingress Guide] as a cross-platform workaround. You can also expose pods and services using extra port mappings as shown in the extra port mappings section of the [Configuration Guide]. - [Metallb]: https://metallb.universe.tf/ + [MetalLB]: https://metallb.universe.tf/ [installation docs]: https://metallb.universe.tf/installation/ [configuration docs]: https://metallb.universe.tf/configuration/ @@ -24,32 +24,35 @@ description: |- --- -## Installing metallb using default manifests +## Installing MetalLB using default manifests -### Apply metallb manifest +### Apply MetalLB manifest Since version 0.13.0, MetalLB is configured via CRs and the original way of configuring it via a ConfigMap based configuration is not working anymore. {{< codeFromInline lang="bash" >}} -kubectl apply -f https://raw.githubusercontent.com/metallb/metallb/v0.13.5/config/manifests/metallb-native.yaml +kubectl apply -f https://raw.githubusercontent.com/metallb/metallb/v0.13.7/config/manifests/metallb-native.yaml {{< /codeFromInline >}} -Wait for metallb pods to have a status of Running +Wait until the MetalLB pods (controller and speakers) are ready: {{< codeFromInline lang="bash" >}} -kubectl get pods -n metallb-system --watch +kubectl wait --namespace metallb-system \ + --for=condition=ready pod \ + --selector=app=metallb \ + --timeout=90s {{< /codeFromInline >}} ### Setup address pool used by loadbalancers -To complete layer2 configuration, we need to provide metallb a range of IP addresses it controls.
