Pedro Almeida 25f9cc35db Update cert-manager version to v1 from v1alpha2

Following the cert-manager migration to FluxCD, it was upversioned to
v1.7.1 from v0.41.2, which means we need to update our helm-chart
docs to use v1 instead of v1alpha2.

Configure Docker Registry Certificate

The local Docker registry provides secure HTTPS access using the registry API.

By default, a self-signed server certificate is generated at installation time for the registry API. For more secure access, an intermediate or Root CA-signed server certificate is strongly recommended.

To configure or update the HTTPS certificate for the local Docker registry, create a certificate named system-registry-local-certificate in the deployment namespace. The secretName attribute of this certificate's spec must also be named system-registry-local-certificate.

See the example procedure below for creating the certificate for the local Docker registry. This example assumes you have configured a system-local-ca ClusterIssuer as described in starlingx-rest-api-applications-and-the-web-admin-server-cert-9196c5794834.

Update the following fields:

The duration and renewBefore dates for the expiry and renewal times you desire. The system will automatically renew and re-install the certificate.
The subject fields to identify your particular system.
The ipAddresses with the Floating IP Address and the MGMT Floating IP address for this system. Use the system addrpool-list command to get the floating IP Address and management floating IP Address for your system.
The dnsNames with registry.local, registry.central and any names configured for this system's Floating IP Address in an external DNS server.

Create the Docker certificate yaml configuration file.

~(keystone_admin)]$ cat <<EOF > docker-certificate.yaml
---
apiVersion: cert-manager.io/v1
kind: Certificate
metadata:
  name: system-registry-local-certificate
  namespace: deployment
spec:
  secretName: system-registry-local-certificate
  issuerRef:
    name: system-local-ca
    kind: ClusterIssuer
  duration: 2160h    # 90d
  renewBefore: 360h  # 15d
  subject:
    organizations:
      - ABC-Company
    organizationalUnits:
      - StarlingX-system-registry-local
  ipAddresses:
    - <OAM_FLOATING_IP>
    - <MGMT_FLOATING_IP>
  dnsNames:
    - registry.local
    - registry.central
    - <external-FQDN-for-OAM-Floating-IP-Address, if applicable>

Apply the configuration.

~(keystone_admin)]$ kubectl apply -f docker-certificate.yaml

Verify the configuration.
```
~(keystone_admin)]$ kubectl get certificate system-registry-local-certificate –n deployment
```
If configuration was successful, the certificate’s Ready status will be True.

The Docker registry certificate installation is now complete, and Cert-Manager will handle the lifecycle management of the certificate.
