| MetalLB | ||
| ------- | ||
|
|
||
| MetalLB is a load-balancer implementation for bare metal [Kubernetes][k8s-home] | ||
| clusters, using standard routing protocols. | ||
|
|
||
| TL;DR; | ||
| ------ | ||
|
|
||
| ```console | ||
| $ helm install --name metallb stable/metallb | ||
| ``` | ||
|
|
||
| Introduction | ||
| ------------ | ||
|
|
||
| This chart bootstraps a [MetalLB][metallb-home] installation on | ||
| a [Kubernetes][k8s-home] cluster using the [Helm][helm-home] package manager. | ||
| This chart provides an implementation for LoadBalancer Service objects. | ||
|
|
||
| MetalLB is a cluster service, and as such can only be deployed as a | ||
| cluster singleton. Running multiple installations of MetalLB in a | ||
| single cluster is not supported. | ||
|
|
||
| Prerequisites | ||
| ------------- | ||
|
|
||
| - Kubernetes 1.9+ | ||
|
|
||
| Installing the Chart | ||
| -------------------- | ||
|
|
||
| The chart can be installed as follows: | ||
|
|
||
| ```console | ||
| $ helm install --name metallb stable/metallb | ||
| ``` | ||
|
|
||
| The command deploys MetalLB on the Kubernetes cluster. This chart does | ||
| not provide a default configuration; MetalLB will not act on your | ||
| Kubernetes Services until you provide | ||
| one. The [configuration](#configuration) section lists various ways to | ||
| provide this configuration. | ||
|
|
||
| Uninstalling the Chart | ||
| ---------------------- | ||
|
|
||
| To uninstall/delete the `metallb` deployment: | ||
|
|
||
| ```console | ||
| $ helm delete metallb | ||
| ``` | ||
|
|
||
| The command removes all the Kubernetes components associated with the | ||
| chart, but will not remove the release metadata from `helm` — this will prevent | ||
| you, for example, if you later try to create a release also named `metallb`). To | ||
| fully delete the release and release history, simply [include the `--purge` | ||
| flag][helm-usage]: | ||
|
|
||
| ```console | ||
| $ helm delete --purge metallb | ||
| ``` | ||
|
|
||
| Configuration | ||
| ------------- | ||
|
|
||
| See `values.yaml` for configuration notes. Specify each parameter | ||
| using the `--set key=value[,key=value]` argument to `helm | ||
| install`. For example, | ||
|
|
||
| ```console | ||
| $ helm install --name metallb \ | ||
| --set rbac.create=false \ | ||
| stable/metallb | ||
| ``` | ||
|
|
||
| The above command disables the use of RBAC rules. | ||
|
|
||
| Alternatively, a YAML file that specifies the values for the above | ||
| parameters can be provided while installing the chart. For example, | ||
|
|
||
| ```console | ||
| $ helm install --name metallb -f values.yaml stable/metallb | ||
| ``` | ||
|
|
||
| By default, this chart does not install a configuration for MetalLB, and simply | ||
| warns you that you must follow [the configuration instructions on MetalLB's | ||
| website][metallb-config] to create an appropriate ConfigMap. | ||
|
|
||
| If you have a more complex configuration and want Helm to manage it for you, you | ||
| can provide it in the `config` parameter. The configuration format is | ||
| [documented on MetalLB's website][metallb-config]. | ||
|
|
||
| ```console | ||
| $ cat values.yaml | ||
| configInline: | ||
| peers: | ||
| - peer-address: 10.0.0.1 | ||
| peer-asn: 64512 | ||
| my-asn: 64512 | ||
| address-pools: | ||
| - name: default | ||
| protocol: bgp | ||
| cidr: | ||
| - 198.51.100.0/24 | ||
|
|
||
| $ helm install --name metallb -f values.yaml stable/metallb | ||
| ``` | ||
