Chapter 4. Installing the CRDs and controller using YAML

As an alternative to the Red Hat Service Interconnect Operator, you can use YAML to install the CRDs and controller.

Prerequisites

Procedure

Download YAML files, choose the latest Version for 2.2 at Software Downloads and download the Skupper deployments (yamls).
Determine the scope of the installation:
- cluster - You can create a site in any namespace (skupper-cluster-scope-2.2.1-rh.yaml).
- namespace - Although the installation affects the entire cluster, you can only create a site in the namespace where the YAML is deployed (skupper-namespace-scope-2.2.1-rh.yaml).
To install Red Hat Service Interconnect cluster wide, apply the YAML:
```
$ kubectl apply -f skupper-cluster-scope-2.2.1-rh.yaml
```
Note
This YAML installs the controller and supporting resources in the skupper namespace.

To install Red Hat Service Interconnect in a specific namespace:

Create a namespace, for example:

$ kubectl create namespace west
$ kubectl config set-context --current --namespace west

Apply the namespace scoped YAML:

$ kubectl apply -f skupper-namespace-scope-2.2.1-rh.yaml
