This article instructs on how to integrate on-prem Kubernetes Clusters with Cloudaware.

Adding Kubernetes Cluster

1. Log in to your Cloudaware account. Select Admin under your username in the upper right corner.

2. Locate Kubernetes in the list of Cloud Integrations. Click +Add.

3. Click Get New Certificate Request.

Insert the username that will be utilized in Kubernetes. Click Generate.

As a result, a certificate will be generated in .csr format (e.g. cloudaware_test.csr)

4. Sign the Cloudaware certificate request that will be used by Kubernetes control plane node - see the example below:

openssl x509 -req -in cloudaware_test.csr -CA /etc/kubernetes/pki/ca.crt -CAkey /etc/kubernetes/pki/ca.key -CAcreateserial -out cloudaware_test.crt -days 3650

5. Set up authorization for the user on RBAC level. Create a custom Cluster role node-reader for Cloudaware to be able to fetch the information about Cluster nodes:

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  name: node-reader
rules:
- apiGroups: [""]
  resources: ["nodes"]
  verbs: ["get", "watch", "list"]
CODE

Create a RoleBinding - see the sample command below:

kubectl create -f cloudaware-user.yaml
CODE

Two bindings are in use, the first one binds the default role view, the second one binds the custom Cluster role node-reader:

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: cloudaware_test-binding
subjects:
- kind: User
  name: cloudaware_test
  namespace: default
  apiGroup: ""
roleRef:
  kind: ClusterRole
  name: view
  apiGroup: ""
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: cloudaware_test-binding2
subjects:
- kind: User
  name: cloudaware_test
  namespace: default
  apiGroup: ""
roleRef:
  kind: ClusterRole
  name: node-reader
  apiGroup: ""
CODE

5. Once the certificate is signed, go back to Cloudaware. Insert Cluster URL* and click Upload Signed Certificate to upload the certificate. Click Save.

*If your Kubernetes Cluster is public, use a direct web link in 'Cluster URL'.

If your Kubernetes Cluster is private, install Breeze agent, set up TunHub Gateway and use the TunHub route URL (e.g. https://tunhub.cloudaware.com:12345) in 'Cluster URL'.
