Installing the OpenStack Client

Use this procedure to install the OpenStack CLI tool.

1. Install the OpenStack client CLI tool on the primary Ubuntu host.

   content_copy zoom_out_map

   apt install python-dev python-pip -y
   pip install --upgrade pip
   pip install python-openstackclient    OR
   apt-get install python-openstackclient

2. If you have problems installing the python-dev package, add another repository.

   content_copy zoom_out_map

   Add following repo to source "/etc/apt/sources.list"
   deb http://archive.ubuntu.com/ubuntu/ xenial-updates main universe multiverse
   apt-get update
   apt-get install python-dev

Create openstackrc File and Test OpenStack Client

1. Create an openstackrc file.

   content_copy zoom_out_map

   cat > /root/openstackrc << EOF
   export OS_USERNAME=admin
   export OS_PASSWORD=password
   export OS_TENANT_NAME=admin
   export OS_AUTH_URL=http://keystone-api.openstack:35357/v3
   # The following lines can be omitted
   #export OS_TENANT_ID=tenantIDString
   #export OS_REGION_NAME=regionName
   export OS_IDENTITY_API_VERSION=3
   export OS_USER_DOMAIN_NAME=${OS_USER_DOMAIN_NAME:-"Default"}
   export OS_PROJECT_DOMAIN_NAME=${OS_PROJECT_DOMAIN_NAME:-"Default"}
   EOF

2. Test the OpenStack client.

   content_copy zoom_out_map

   source openstackrc
   openstack server list
   openstack stack list
   openstack --help

Accessing the Contrail Web UI

1. Access the Contrail Web UI using port 8143. Use the IP address of the host where the contrail-webui pod is running, with the port 8143.

   content_copy zoom_out_map

   https://<IP address host with contrail-webui>:8143

2. At the Contrail login screen, enter the default username and password: admin, password.

Accessing OpenStack Horizon

The OpenStack Web UI (GUI) service is exposed by the Kubernetes service, using the IP address of the node port and the default port 31000.

1. Check the NodePort used for the OpenStack Web UI pod.

   content_copy zoom_out_map

   kubectl get svc -n openstack | grep horizon-int
   horizon-int           NodePort    10.99.150.28     <none>        80:31000/TCP         4d

2. Access the OpenStack Web UI and log in with the default username and password: admin, password.

   content_copy zoom_out_map

   http://<IP address NodePort>:31000/auth/login/?next=/
   

Accessing the Virtual Machine Console from Horizon

To access the virtual machine (VM) console, add the nova novncproxy fully-qualified domain name (FQDN) in the /etc/hosts file, using the host-ip where the osh-ingress pod is running.

The following example for MAC-OS shows the ingress pod running on the host with IP address 10.13.82.233.

/private/etc/hosts                                                                                                   
127.0.0.1	localhost
255.255.255.255	broadcasthost
::1             localhost
10.13.82.233 nova-novncproxy.openstack.svc.cluster.local
