Deploying Red Hat OpenStack 10 via the Tripleo UI

tripleo_owl

In this lab, we are going to deploy a functional, yet simple, Overcloud via the Tripleo WebUI using Virtual Machines. Our test deployment will consist of three Overcloud Controller Nodes (configured with HA) and one Overcloud Compute Node.

Prerequisites

Note that we have installed squid on our hypervisor node and are using that node to proxy all web traffic to the undercloud controller. This also requires configuring your web browser to use the hypervisor as its proxy.

Logging into the WebUI

We first need to determine the Admin password for the Tripleo WebUI. We can determine this using the following command.

[stack@undercloud ~]$ sudo hiera admin_password

Now we navigate to the WebUI and log in as Admin using the password above.

Once we log in we are greeted by the screen below.

Create a Plan

Select “Create New Plan“.  Enter the “Plan Name“. Select “Tar Archive (tar.gz)” and select the tarball that you have created of your templates directory. Then select “Upload Files and Create Plan

Note, that you can also upload an entire directory (using Chrome only).

Once complete, your new plan will appear as shown below.

Register Nodes

Now, we need to register our nodes

Select the “Nodes” tab, and then select the blue “Register Nodes” button.

register_nodes

Select “Upload From File” and select your instackenv.json.  The Node Details should pre-fill as shown in the image below.

Now, select “Register Nodes“.

Wait while the nodes are registered. Once the process has completed, select the nodes to be used for your deployment.

In this lab we will deploy using the following nodes:

  • overcloud-ctrl01
  • overcloud-ctrl02
  • overcloud-ctrl03
  • overcloud-compute01

Select the nodes by clicking on the check-box on the left, then select “Introspect Nodes“. See screenshot below.

See, post-introspection screenshot below. Now select your introspected nodes, and select “Provide Nodes” to set them to a provisionable state.

Specify Deployment Configuration

From the “Deployment Plan” tab, select “Edit Configuration” under “Specify Deployment Configuration“. See screenshot below.

specify-dep

A new window labeled “Deployment Configuration“, will appear.  This window has two tabs; “Overall Settings” and “Parameters“.

depoyment-configuration

Overall Settings Tab

Under the tab, “Overall Settings” you can configure items such as network isolation, storage, fluentd logging,  High Availability,  and deploy Neutron Plugins (BSN, Cisco N1KV, OpenDaylight).

overall-settings

As previously mentioned, we are going to deploy three Overcloud Controller Nodes (using HA).

Under “Overall Settings“, Select “Deployment Options” in the left sidebar. Check the “Pacemaker” box under “High Availability“.  See screenshot below.

Parameters Tab

This tab allows you to set parameters specific to the deployment of your overcloud.  Set “ComputeCount =1” and “ControllerCount =3“. See screenshot below.

count

Once complete, select “Save Changes“.

Configure Flavors

We now need to assign a flavor to each role. Note that in this lab, we are only using two flavors, Compute and Control.

control-flavor

Configure Roles and Assign Nodes

First, we will associate the Controller role with the Control Flavor. Click on the blue pencil to edit the Controller Flavor. Under “Controller Role” scroll down until you see the field labeled “OvercloudControlFlavor“. Change “baremetal” to “control“.  Then select “Save Changes“. See below.

control-flav

Now, assign the “compute” flavor to the “Compute Role“.  Follow the same process as you used to assign the Controller flavor.

compute-role

Select “Save Changes“.

Assigning Nodes

Now we need to assign nodes to each role.

roles-nodes

Starting with Controller role, click on “Assign Nodes“.  Select the three controller nodes, select “Assign/Unassign Selected Nodes” then select “Done“. See screenshot below.

Now onto the Compute role. Click on “Assign Nodes“.  Select the compute node, select “Assign/Unassign Selected Nodes” then select “Done“. See screenshot below.

assign-compute-node

Deploying

Once you have assigned three nodes to the “Controller” role and one node to the “Compute” node, it’s time to start our deploy.

Click on “Validate and Deploy

You may see a screen similar to what is shown below. Since this is a lab deployment, and our failed validations are minor, we will proceed.

deploy-validations

A progress screen will appear while the deploy is ongoing. Note, that there is a search box that you can use to search resources that have a status of “CREATE_IN_PROGRESS” or “FAILED“.

See example output below.

progress

Note that the deploy can take a while, so please be patient.

Troubleshooting Deployment Failures

Note, that if your deployment fails, troubleshooting a failed deployment in the Tripleo UI/OSP 10 is much easier than you may be used to.

If your deployment fails, you should see a screen similar to what is shown below.

failed1.png

You can use the Tripleo UI to search for the specific failed resource as shown below.

For more detail on your failure, run the following command, which is new in Red Hat OSP 10, on the undercloud node.

$ openstack stack failures list overcloud

The output of which indicates an issue with galera/mysql. Now I just need to troubleshoot.

  1. Hi!

    Did you solved that problem? I’m facing a very similar one in the same scenario (I’m using RH Director based on TripleO).

    Thanks!
