Basic Deployment (UI)

Basic Deployment (UI)

This document will show you how to access the TripleO UI and perform a simple deployment with some customizations. Validations are automatically run at every step to help uncover potential issues early.

Prepare Your Environment

The UI is installed by default with the undercloud. You can confirm this by opening undercloud.conf and checking for:

enable_ui = true
enable_validations = true

The validations are optional but strongly recommended.

  1. Make sure you have your environment ready and undercloud running:
  2. Make sure the images are uploaded in Glance on the undercloud:

Access the UI

The UI is accessible on the undercloud URL. With the default settings the URLs may look like the following, depending on whether the undercloud was set up with SSL:

The username is admin and the password can be obtained by running the following command on the undercloud:

$ sudo hiera admin_password

Note

On an undercloud deployed without SSL, the UI and API endpoints are deployed on the control plane which may not be routable. In this case you will need to create a tunnel or use a tool such as sshuttle to be able to use the UI from a local browser:

sshuttle -r user@undercloud 192.168.24.0/24

Virtual

If you cannot directly access the undercloud (for example because the undercloud is installed in a VM on a remote lab host), you will need to create a tunnel and make some configuration changes in order to access the UI locally.

  1. Open the tunnel from the virt host, to the undercloud:

    ssh -Nf user@virthost -L 0.0.0.0:443:192.168.24.2:443 # If SSL
    ssh -Nf user@virthost -L 0.0.0.0:3000:192.168.24.1:3000 # If no SSL
    

    Note

    Quickstart started creating the tunnel automatically during Pike. If using an older version you will have to create the tunnel manually, for example:

    ssh -F /root/.quickstart/ssh.config.ansible undercloud -L 0.0.0.0:443:192.168.24.2:443
    
  2. Edit the UI config on the undercloud to replace the undercloud IP with your virt host name, for example:

    sudo sed -i.bak s/192.168.24.2/virthost/ /var/www/openstack-tripleo-ui/dist/tripleo_ui_config.js
    

    Additionally, make sure all the API endpoints are commented out in this file.

    Note

    Changes to tripleo_ui_config.js are overwritten on undercloud upgrades.

  3. You may have to open port 3000 or 443 on your virt host.

    Stable Branch

    Newton

    Starting in Ocata, all the API ports are proxied through 3000 (non-SSL) or 443 (SSL). If using Newton, you will need to ensure ports for all the API endpoints specified in tripleo_ui_config.js are open and accessible. If using SSL with self-signed certificates, Firefox will also require a SSL certificate exception to be accepted for every port.

  4. The UI should now be accessible at http://virthost:3000 or https://virthost.

Manage Plans

A default plan named overcloud is created during the undercloud installation, based on the default tripleo-heat-templates installed on the system. This plan can be customized and deployed.

It is also possible to create and manage additional plans in parallel, in order to test different configurations.

By clicking on “Manage Deployments” beside the deployment name, you can perform actions on plans such as create, export, delete, etc.

Note

There can be confusion with node assignments when switching between plans, particularly in previous releases like Newton. If doing work with multiple plans, ensure the Node counts are what you expect before starting the deployment, for example by navigating to Edit Configuration -> Parameters.

Manage Nodes

Register Nodes

Navigate to the Nodes tab in the top bar and click on the Register Nodes button. New nodes can be added in two ways:

  • Importing an instackenv.json file
  • Manually defining nodes via the Add New button.

Introspect Nodes

Introspection is a required step when deploying from the UI. Once the nodes are registered and in the manageable provision state, select the nodes and click on the Introspect Nodes button.

Provide Nodes

Once introspection is completed, nodes need to be “provided” in order to move to the available state and be available for deployments. Select the nodes and click on the Provide Nodes button.

Note

For more information about node states, see Bare Metal Node States.

Tag Nodes

Nodes need to be tagged to match a specific profile/role before they can be used in a deployment. Select the nodes you want to assign a profile to, then click on Tag Nodes (the option may be in a dropdown menu).

Stable Branch

In Newton and Ocata, node assignment and node tagging are done at the same time when assigning nodes on the Deployment Plan page.

Configure the Deployment

On the Deployment Plan tab, you can configure both the overall deployment, as well as specific roles.

Clicking on the Edit Configuration link displays the list of environments available and their description, based on the templates provided in the plan. After enabling environments as desired, click on Save Changes and navigate to the Parameters tab. Once saved, the enabled environments will also be configurable on this tab.

The Parameters tab lets you set configuration options for the deployment in general, as well as for each individual environment.

Stable Branch

Newton

In Newton it was not possible to configure individual environments. The environment templates should be updated directly with the required parameters before uploading a new plan.

Individual roles can also be configured by clicking on the Pencil icon beside the role name on each card.

Stable Branch

Newton

In Newton, you may need to assign at least one node to the role before the related configuration options are loaded.

Assign Nodes

The second number on each card indicates the number of nodes tagged with this particular profile. The number of nodes manually assigned via the number picker will be deployed.

Stable Branch

In Newton and Ocata, nodes are tagged as part of assigning a node to a profile. This can cause issues when switching deployment plans, as the node counts displayed on the card may not match the value actually stored in the plan. You can correct this by clicking on Edit Configuration -> Parameters and checking/updating the node counts for ControllerCount, ComputeCount, etc.

Additionally, when using custom roles you should make sure to unassign the nodes associated with these roles before deleting the plan, as the role cards are displayed based on the roles in the current plan only. Therefore it is not possible to unassign a node which is associated with a role that does not exist in the current plan.

Deploy the Overcloud

Click on the Deploy button.

You may see a warning if not all validations passed. While this is expected in resources-constrained virtual environments, it is recommended to check the failed validations carefully before proceeding.

The View detailed information link shows the details for all the Heat resources being deployed.

Post-Deployment

Once the deployment completes, the progress bar will be replaced with information about the overcloud such as the IP address and login credentials.

If the deployment failed, information about the failure will be displayed.

Virtual

To access the overcloud, you will need to update your tunnel in order to access the new URL. For example, if your overcloud information is as such:

Overcloud IP address: 192.168.24.12
Username: admin
Password: zzzzzz

Assuming you deployed the overcloud with SSL enabled, you could create the following tunnel from your virt host to the undercloud:

ssh -Nf user@undercloud -L 0.0.0.0:1234:192.168.24.12:443

After opening port 1234 on your virt host, you should be able to access the overcloud by navigating to https://virthost:1234.
