You can access the Operations Hub home page using the following URL:

https://{Hostname}

Hostname is the Fully Qualified Domain Name (FQDN) of the Cisco Operations Hub cluster, which is configured using the ingress-hostname key of the deployer configuration. If the Cisco Operations Hub cluster is deployed without the ingress-hostname key, then you must use the Hostname format as {vip}.nip.io, where vip is the virtual IP address of the Cisco Operations Hub cluster.

We recommend that you use FQDN for the Operations Hub cluster.

Once you deploy the Operations Hub successfully, you can navigate through the Operations Hub Web User Interface (UI) from the Main Menu.

The following table highlights the navigation options in Operations Hub:

This section explains how you can use REST APIs.

1. Create a user.

   To create a new user, see Adding Users procedure in Managing Users.

2. Call auth REST API to create a token.

   Encode the username and password with base 64. Fill the encode output into the Authentication Header.

   The following is a sample configuration to use REST API:

   User: admin
   Password: bell
   
   Get the Base64 under Linux: echo -n 'admin:lab' | base64
   Base64 encode output: YWRtaW46bGFi
   
   curl -X POST "https://{Hostname}/api/auth/v1/token" -H  "accept: application/json" -H  "authorization: Basic YWRtaW46bGFi"
   
   Response code: 201

When you deploy the Cisco Operations Hub cluster, the cluster is configured with a selfsigned certificate by default. You can deploy the cluster with a CA-signed certificate before running deploy script.

Use this task to deploy the cluster with the CA-signed certificate.

1. Generate a CA-signed certificate with a common name as "ingress-hostname" used in the day 0 configuration YAML file.

2. On the staging server, create a directory with the cluster name as the directory name under the path: "/certs/client_certificates". For example, if you use the cluster name as "testcluster", then the directory name must be "/certs/client_certificates/testcluster". This directory is the cluster ingress certificates directory.

3. Create the "cert-api-ingress" and "default-ssl-certificate" directories under the cluster ingress certificates directory.

4. Place the CA-signed certificate and keys under the "cert-api-ingress" directory. The CA signed certificate file has ".crt" extension and key file has ".key" extension.
