docs: restructure docs Introduce two main sections "Deployment" and "Usage" and move "Developer guide" to the top level, too. In particular, split the huge deployment-and-usage file into multiple parts under the new main sections. Move customization guide from "Advanced" to "Usage". This patch also renames "Advanced" to "Reference" as only that is left there is reference documentation.

## Prerequisites
[Helm package manager](https://helm.sh/) should be installed.
## Deployment
To install the latest stable version:
```bash
export NFD_NS=node-feature-discovery
helm repo add nfd https://kubernetes-sigs.github.io/node-feature-discovery/charts
helm repo update
helm install nfd/node-feature-discovery --namespace $NFD_NS --create-namespace --generate-name
```
To install the latest development version you need to clone the NFD Git
repository and install from there.
```bash
git clone https://github.com/kubernetes-sigs/node-feature-discovery/
cd node-feature-discovery/deployment/helm
export NFD_NS=node-feature-discovery
helm install node-feature-discovery ./node-feature-discovery/ --namespace $NFD_NS --create-namespace
```
See the [configuration](#configuration) section below for instructions how to
alter the deployment parameters.
## Configuration
You can override values from `values.yaml` and provide a file with custom values:
```bash
export NFD_NS=node-feature-discovery
helm install nfd/node-feature-discovery -f <path/to/custom/values.yaml> --namespace $NFD_NS --create-namespace
```
To specify each parameter separately you can provide them to helm install command:
```bash
export NFD_NS=node-feature-discovery
helm install nfd/node-feature-discovery --set nameOverride=NFDinstance --set master.replicaCount=2 --namespace $NFD_NS --create-namespace
```

## Upgrading the chart
To upgrade the `node-feature-discovery` deployment to {{ site.release }} via Helm.
### From v0.7 and older

2024-10-18 11:36:46 +02:00
Please see

Add helm migration guide Signed-off-by: Carlos Eduardo Arango Gutierrez <eduardoa@nvidia.com>
2024-07-23 13:26:11 +02:00
And then follow the standard [deployment instructions](#deployment).
### From v0.8 - v0.11
Helm deployment of NFD was introduced in v0.8.0.
```bash
export NFD_NS=node-feature-discovery
# Uninstall the old NFD deployment
helm uninstall node-feature-discovery --namespace $NFD_NS
# Update Helm repository
helm repo update
# Install the new NFD deployment
helm upgrade --install node-feature-discovery nfd/node-feature-discovery --namespace $NFD_NS --set master.enable=false
# Wait for NFD Worker to be ready
kubectl wait --timeout=-1s --for=condition=ready pod -l app.kubernetes.io/name=node-feature-discovery --namespace $NFD_NS
# Enable the NFD Master
helm upgrade --install node-feature-discovery nfd/node-feature-discovery --namespace $NFD_NS --set master.enable=true
```
### From v0.12 - v0.13
In v0.12 the `NodeFeature` CRD was introduced as experimental.
The API was not enabled by default.
```bash
export NFD_NS=node-feature-discovery
# Update Helm repository
helm repo update
# Install and upgrade CRD's
kubectl apply -f https://raw.githubusercontent.com/kubernetes-sigs/node-feature-discovery/master/deployment/base/nfd-crds/nfd-api-crds.yaml
# Install the new NFD deployment
helm upgrade node-feature-discovery nfd/node-feature-discovery --namespace $NFD_NS --set master.enable=false
# Wait for NFD Worker to be ready
kubectl wait --timeout=-1s --for=condition=ready pod -l app.kubernetes.io/name=node-feature-discovery --namespace $NFD_NS
# Enable the NFD Master
helm upgrade node-feature-discovery nfd/node-feature-discovery --namespace $NFD_NS --set master.enable=true
```
### From v0.14+
As of version v0.14 the Helm chart is the primary deployment method for NFD,
and the CRD `NodeFeature` is enabled by default.
```bash
export NFD_NS=node-feature-discovery
# Update Helm repository
helm repo update
# Install and upgrade CRD's
kubectl apply -f https://raw.githubusercontent.com/kubernetes-sigs/node-feature-discovery/{{ site.release }}/deployment/base/nfd-crds/nfd-api-crds.yaml
# Install the new NFD deployment
helm upgrade node-feature-discovery nfd/node-feature-discovery --namespace $NFD_NS
```
