This section explains how to create SEs using heat templates in a no-access mode.

Prerequisites

Ensure the following:

  • Heat stack is installed on the OpenStack Controller node.

  • Cloud is on no-orchestrator type.

  • SE image is downloaded as qcow2 and has been pushed into Glance. For more details, see Installing Avi Load Balancer OpenStack in No-Access OpenStack Cloud section.

  • Heat template files are present on the OpenStack Controller node. You can download the files from this location.

Deploying an Avi Load Balancer Service Engine

You can deploy the Service Engine as follows:

  • Edit the se-no- orc-env.yaml file and alter the following parameters as explained:

se_networks: avimgmt, client-network, webserver- network, provider1.

The SE can be part of:

  • num_se_networks: 4 - This is the number of networks that the SE is part of.

  • allowed_address_cidr: 12.10.0.0/24 - AAP entry.

  • avi_se_name: OS-SE- No-Orch - An arbitrary name for the SE.

  • auth_token: 4c7f5489-df57- 4f4d-a5b6- c6fa5fb88ea5 - Needs to be fetched from the Avi Load Balancer UI.

  • controller_ip: 10.140.4.46 - Avi Load Balancer Controller IP.

  • avi_se_flavor: m1.small - The flavor needed to spin up the SE. Ensure that this flavor exists in the OpenStack Controller node.

  • avi_se_image: Avi-SE- OS-No- Orch - The name of the SE image which is created from Horizon or using CLI.

Note:

  • If multi-tenancy has to be used, ensure that the token is used or fetched from the respective tenant in Avi Load Balancer UI and is populated in the yaml file.

  • In case more than one SE has to be spinned up, the YAML file has to run with a different token as Avi Load Balancer uses only one token per SE per tenant.

Creating Service Engine using Heat-Templates

You can create SE using heat-templates as follows:

heat stack-create -f se-no-orc.yaml -e ./se-no-orc-env.yaml ocata

Where, ocata is the name of the heat-stack that we are creating.

Check the stack creation using the following command:

root@openstack-ocata:/root# openstack stack list
+--------------------------------------+------------+-----------------+----------------------+--------------+
 | ID                                   | Stack Name | Stack Status    | Creation Time        | Updated Time |
 +--------------------------------------+------------+-----------------+----------------------+--------------+
 | 45c44c59-7d24-4d41-ac93-0d6f4200d5b5 | ocata      | CREATE_COMPLETE | 2017-12-06T08:41:48Z | None         |
 +--------------------------------------+------------+-----------------+----------------------+--------------+

Check the server list using the following command:

root@openstack-ocata:/root# openstack server list
