Red Hat OpenStack Administration I: Core Operations for Domain Operators

Procedure 8.2. Instructions

1. Source the /home/student/operator1-finance-rc credentials file to enable administrator privileges, and deploy the 3-tier web application using the /home/student/3tier-stack.yml Heat template.

   [student@workstation ~]$ source ~/operator1-finance-rc
   [student@workstation ~(operator1-research)]$

   1. Review the /home/student/3tier-stack.yml Heat template.

   2. Use the openstack stack create command to deploy the 3-tier stack.

      [student@workstation ~(operator1-finance)]$ openstack stack create \
      > -t 3tier-stack.yml apptracker
      +---------------------+--------------------------------------+
      | Field               | Value                                |
      +---------------------+--------------------------------------+
      | id                  | 7523351e-aec2-4f8d-9110-be3390c467a0 |
      | stack_name          | apptracker                           |
      | description         | application-tracker                  |
      | creation_time       | 2020-08-27T10:08:58Z                 |
      | updated_time        | None                                 |
      | stack_status        | CREATE_IN_PROGRESS                   |
      | stack_status_reason | Stack CREATE started                 |
      +---------------------+--------------------------------------+

   3. Use the openstack server list command to view the deployed servers from the template.

      [student@workstation ~(operator1-finance)]$ openstack server list \
      > -c ID -c Name -c Status -c Networks
      +-----------+------------+--------+---------------------------------------------+
      | ID        | Name       | Status | Networks                                    |
      +-----------+------------+--------+---------------------------------------------+
      | 49e...c48 | app_server | ACTIVE | app_app=192.168.8.10                        |
      | 88c...f81 | web        | ACTIVE | external_network=192...7.10, 172.25.250.171 |
      | 04d...d91 | database   | ACTIVE | app_db=192.168.9.10                         |
      +-----------+------------+--------+---------------------------------------------+

   4. Use the openstack floating ip list command to view the used floating IP address that will be used to access the application.

      [student@workstation ~(operator1-finance)]$ openstack floating ip list
      +-----------+---------------------+------------------+-----------+
      | ID        | Floating IP Address | Fixed IP Address | Port      |
      +-----------+---------------------+------------------+-----------+
      | 1cf...48c | 172.25.250.171      | 192.168.7.10     | c9c...a8c |
      +-----------+---------------------+------------------+-----------+

2. On workstation, open a web browser and navigate to the floating IP address obtained from the previous step.

   1. Add an item to the queue to verify that the application is working.

   2. Use the openstack console url show command with the server ID obtained from the openstack server list command to obtain the novnc console URL to access the individual instances.

      [student@workstation ~(operator1-finance)]$ openstack console url \
      > show 88c87f40-6f7a-4a4d-87d3-3793e0608689
      +-------+---------------------------------------------------------+
      | Field | Value                                                   |
      +-------+---------------------------------------------------------+
      | type  | novnc                                                   |
      | url   | http://172.25.250.50:6080/vnc_auto.html?path=%3Ft...62d |
