Basic Deployment (CLI)

With these few steps you will be able to simply deploy via TripleO to your environment using our defaults in a few steps.

Prepare Your Environment

  1. Make sure you have your environment ready and undercloud running:

  2. Log into your undercloud (instack) virtual machine as non-root user:

    ssh root@<undercloud-machine>
    su - stack
  3. In order to use CLI commands easily you need to source needed environment variables:

    source stackrc

Get Images


If you already have images built, perhaps from a previous installation of TripleO, you can simply copy those image files into your regular user’s home directory and skip this section.

If you do this, be aware that sometimes newer versions of TripleO do not work with older images, so if the deployment fails it may be necessary to delete the older images and restart the process from this step.

Alternatively, images are available via RDO at which offers images from both the CentOS Build System (cbs) and RDO Trunk (called rdo_trunk or delorean). However this mirror is slow so if you experience slow download speeds you should skip to building the images instead.

The image files required are:


Images must be built prior to doing a deployment. An IPA ramdisk and openstack-full image can all be built using tripleo-common.

It’s recommended to build images on the installed undercloud directly since all the dependencies are already present, but this is not a requirement.

The following steps can be used to build images. They should be run as the same non-root user that was used to install the undercloud. If the images are not created on the undercloud, one should use a non-root user.

  1. Choose image operating system:


    The image build with no arguments will build CentOS 7. It will include the common YAML of /usr/share/openstack-tripleo-common/image-yaml/overcloud-images.yaml and the CentOS YAML at /usr/share/openstack-tripleo-common/image-yaml/overcloud-images-centos7.yaml.


    The common YAML is /usr/share/openstack-tripleo-common/image-yaml/overcloud-images.yaml. It must be specified along with the following.

    The default YAML for RHEL is /usr/share/openstack-tripleo-common/image-yaml/overcloud-images-rhel7.yaml

    export OS_YAML="/usr/share/openstack-tripleo-common/image-yaml/overcloud-images/rhel7.yaml"
  2. Install the current-tripleo delorean repository and deps repository:

Stable Branch

Enable the appropriate repos for the desired release, as indicated below. Do not enable any other repos not explicitly marked for that release.


Enable latest RDO Newton Delorean repository for all packages

sudo curl -L -o /etc/yum.repos.d/delorean-newton.repo

Enable the Newton Delorean Deps repository

sudo curl -L -o /etc/yum.repos.d/delorean-deps-newton.repo


Enable the CentOS Storage SIG Ceph/Jewel repository if using Ceph

sudo yum -y install --enablerepo=extras centos-release-ceph-jewel
sudo sed -i -e 's%gpgcheck=.*%gpgcheck=0%' /etc/yum.repos.d/CentOS-Ceph-Jewel.repo


Enable latest RDO Ocata Delorean repository for all packages

sudo curl -L -o /etc/yum.repos.d/delorean-ocata.repo

sudo sed -i -e 's%gpgcheck=.*%gpgcheck=0%' /etc/yum.repos.d/CentOS-Ceph-Jewel.repo

Enable last known good RDO Trunk Delorean repository for core openstack packages

sudo curl -L -o /etc/yum.repos.d/delorean.repo

Enable latest RDO Trunk Delorean repository only for the TripleO packages

sudo curl -L -o /etc/yum.repos.d/delorean-current.repo
sudo sed -i 's/\[delorean\]/\[delorean-current\]/' /etc/yum.repos.d/delorean-current.repo
sudo /bin/bash -c "cat <<EOF>>/etc/yum.repos.d/delorean-current.repo


Enable the Delorean Deps repository

sudo curl -L -o /etc/yum.repos.d/delorean-deps.repo


Enable the CentOS Storage SIG Ceph/Jewel repository if using Ceph

sudo yum -y install --enablerepo=extras centos-release-ceph-jewel
sudo sed -i -e 's%gpgcheck=.*%gpgcheck=0%' /etc/yum.repos.d/CentOS-Ceph-Jewel.repo
  1. Export environment variables

    export DIB_YUM_REPO_CONF="/etc/yum.repos.d/delorean*"


    export DIB_YUM_REPO_CONF="$DIB_YUM_REPO_CONF /etc/yum.repos.d/CentOS-Ceph-Jewel.repo"

    Stable Branch


    export STABLE_RELEASE="newton"


    export DIB_YUM_REPO_CONF="$DIB_YUM_REPO_CONF /etc/yum.repos.d/CentOS-Ceph-Jewel.repo"


    export STABLE_RELEASE="ocata"


    export DIB_YUM_REPO_CONF="$DIB_YUM_REPO_CONF /etc/yum.repos.d/CentOS-Ceph-Jewel.repo"
  2. Build the required images:


Download the RHEL 7.3 cloud image or copy it over from a different location, for example:, and define the needed environment variables for RHEL 7.3 prior to running tripleo-build-images:

export DIB_LOCAL_IMAGE=rhel-guest-image-7.3-35.x86_64.qcow2

RHEL Portal Registration

To register the image builds to the Red Hat Portal define the following variables:

export REG_METHOD=portal
export REG_USER="[your username]"
export REG_PASSWORD="[your password]"
# Find this with `sudo subscription-manager list --available`
export REG_POOL_ID="[pool id]"
export REG_REPOS="rhel-7-server-rpms rhel-7-server-extras-rpms rhel-ha-for-rhel-7-server-rpms \
    rhel-7-server-optional-rpms rhel-7-server-openstack-6.0-rpms"


If using Ceph, additional channels need to be added to REG_REPOS. Enable the appropriate channels for the desired release, as indicated below. Do not enable any other channels not explicitly marked for that release.


RHEL Satellite Registration

To register the image builds to a Satellite define the following variables. Only using an activation key is supported when registering to Satellite, username/password is not supported for security reasons. The activation key must enable the repos shown:

export REG_METHOD=satellite
# REG_SAT_URL should be in the format of:
# http://<satellite-hostname>
export REG_SAT_URL="[satellite url]"
export REG_ORG="[satellite org]"
# Activation key must enable these repos:
# rhel-7-server-rpms
# rhel-7-server-optional-rpms
# rhel-7-server-extras-rpms
# rhel-7-server-openstack-6.0-rpms
# rhel-7-server-rhceph-{2,1.3}-mon-rpms
# rhel-7-server-rhceph-{2,1.3}-osd-rpms
# rhel-7-server-rhceph-{2,1.3}-tools-rpms
export REG_ACTIVATION_KEY="[activation key]"


Git checkouts of the puppet modules can be used instead of packages. Export the following environment variable:

export DIB_INSTALLTYPE_puppet_modules=source

It is also possible to use this functionality to use an in-progress review as part of the overcloud image build. See Using an In-Progress Review for details.

openstack overcloud image build


openstack overcloud image build --config-file /usr/share/openstack-tripleo-common/image-yaml/overcloud-images.yaml --config-file $OS_YAML

See the help for openstack overcloud image build for further options.

The YAML files are cumulative. Order on the command line is important. The packages, elements, and options sections will append. All others will overwrite previously read values.


This command will build overcloud-full images (*.qcow2, *.initrd, *.vmlinuz) and ironic-python-agent images (*.initramfs, *.kernel)

In order to build specific images, one can use the --image-name flag to openstack overcloud image build. It can be specified multiple times.


If you want to use whole disk images with TripleO, please see Use whole disk images for overcloud.

Upload Images

Load the images into the undercloud Glance:

openstack overcloud image upload

To upload a single image, see Uploading a Single Image.

Register Nodes

Register and configure nodes for your deployment with Ironic:

openstack overcloud node import instackenv.json

The file to be imported may be either JSON, YAML or CSV format, and the type is detected via the file extension (json, yaml, csv). The file format is documented in instackenv.json.

The nodes status will be set to manageable by default, so that introspection may later be run. To also run introspection and make the nodes available for deployment in one step, the following flags can be used:

openstack overcloud node import --introspect --provide instackenv.json

Starting with the Newton release you can take advantage of the enroll provisioning state - see Bare Metal Node States for details.

If your hardware has several hard drives, it’s highly recommended that you specify the exact device to be used during introspection and deployment as a root device. Please see Setting the Root Device for Deployment for details.


If you don’t specify the root device explicitly, any device may be picked. Also the device chosen automatically is NOT guaranteed to be the same across rebuilds. Make sure to wipe the previous installation before rebuilding in this case.


It’s not recommended to delete nodes and/or rerun this command after you have proceeded to the next steps. Particularly, if you start introspection and then re-register nodes, you won’t be able to retry introspection until the previous one times out (1 hour by default). If you are having issues with nodes after registration, please follow Node Registration Problems.

Introspect Nodes


Once the undercloud is installed, you can run the pre-introspection validations:

openstack workflow execution create tripleo.validations.v1.run_groups '{"group_names": ["pre-introspection"]}'

Then verify the results as described in Running a group of validations.

Nodes must be in the manageable provisioning state in order to run introspection. Introspect hardware attributes of nodes with:

openstack overcloud node introspect --all-manageable

Nodes can also be specified individually by UUID. The --provide flag can be used in order to move the nodes automatically to the available provisioning state once the introspection is finished, making the nodes available for deployment.

openstack overcloud node introspect --all-manageable --provide


Introspection has to finish without errors. The process can take up to 5 minutes for VM / 15 minutes for baremetal. If the process takes longer, see Hardware Introspection Problems.


If you need to introspect just a single node, see Introspecting a Single Node

Provide Nodes

Only nodes in the available provisioning state can be deployed to (see Bare Metal Node States for details). To move nodes from manageable to available the following command can be used:

openstack overcloud node provide --all-manageable

Flavor Details

The undercloud will have a number of default flavors created at install time. In most cases these flavors do not need to be modified, but they can be if desired. By default, all overcloud instances will be booted with the baremetal flavor, so all baremetal nodes must have at least as much memory, disk, and cpu as that flavor.

In addition, there are profile-specific flavors created which can be used with the profile-matching feature. For more details on deploying with profiles, see Advanced Profile Matching.

Configure a nameserver for the Overcloud

Overcloud nodes can have a nameserver configured in order to resolve hostnames via DNS. The nameserver is defined in the undercloud’s neutron subnet. If needed, define the nameserver to be used for the environment:

# List the available subnets
openstack subnet list
openstack subnet set <subnet-uuid> --dns-nameserver <nameserver-ip>

Stable Branch

For Mitaka release and older, the subnet commands are executed within the neutron command:

neutron subnet-list
neutron subnet-update <subnet-uuid> --dns-nameserver <nameserver-ip>


A public DNS server, such as or the undercloud DNS name server can be used if there is no internal DNS server.


In virtual environments, the libvirt default network DHCP server address, typically, can be used as the overcloud nameserver.

Deploy the Overcloud


Before you start the deployment, you may want to run the pre-deployment validations:

openstack workflow execution create tripleo.validations.v1.run_groups '{"group_names": ["pre-deployment"]}'

Then verify the results as described in Running a group of validations.

By default 1 compute and 1 control node will be deployed, with networking configured for the virtual environment. To customize this, see the output of:

openstack help overcloud deploy


Swap files or partitions can be installed as part of an Overcloud deployment. For adding swap files there is no restriction besides having 4GB available on / (by default). When using a swap partition, the partition must exist and be tagged as swap1 (by default). To deploy a swap file or partition in each Overcloud node use one of the following arguments when deploying:

-e /usr/share/openstack-tripleo-heat-templates/environments/enable-swap-partition.yaml
-e /usr/share/openstack-tripleo-heat-templates/environments/enable-swap.yaml


When deploying Ceph with dedicated CephStorage nodes to host the CephOSD service it is necessary to specify the number of CephStorage nodes to be deployed and to provide some additional parameters to enable usage of Ceph for Glance, Cinder, Nova or all of them. To do so, use the following arguments when deploying:

--ceph-storage-scale <number of nodes> -e /usr/share/openstack-tripleo-heat-templates/environments/storage-environment.yaml

When deploying Ceph without dedicated CephStorage nodes, opting for an HCI architecture instead, where the CephOSD service is colocated with the NovaCompute service on the Compute nodes, use the following arguments:

-e /usr/share/openstack-tripleo-heat-templates/environments/hyperconverged-ceph.yaml -e /usr/share/openstack-tripleo-heat-templates/environments/storage-environment.yaml

The hyperconverged-ceph.yaml environment file will also enable a port on the StorageMgmt network for the Compute nodes. This will be the Ceph private network and the Compute NIC templates have to be configured to use that, see Configuring Network Isolation for more details on how to do it.

RHEL Satellite Registration

To register the Overcloud nodes to a Satellite add the following flags to the deploy command:

--rhel-reg --reg-method satellite --reg-org <ORG ID#> --reg-sat-url <satellite URL> --reg-activation-key <KEY>


Only using an activation key is supported when registering to Satellite, username/password is not supported for security reasons. The activation key must enable the following repos:






To deploy an overcloud with SSL, see Deploying with SSL.

Run the deploy command, including any additional parameters as necessary:

openstack overcloud deploy --templates [additional parameters]

To deploy an overcloud with multiple controllers and achieve HA, follow Configuring High Availability.


When deploying the Compute node in a virtual machine without nested guest support, add --libvirt-type qemu or launching instances on the deployed overcloud will fail.


To deploy the overcloud with network isolation, bonds, and/or custom network interface configurations, instead follow the workflow here to deploy: Configuring Network Isolation


Previous versions of the client had many parameters defaulted. Some of these parameters are now pulling defaults directly from the Heat templates. In order to override these parameters, one should use an environment file to specify these overrides, via ‘parameter_defaults’.

The parameters that controlled these parameters will be deprecated in the client, and eventually removed in favor of using environment files.



After the deployment finished, you can run the post-deployment validations:

openstack workflow execution create tripleo.validations.v1.run_groups '{"group_names": ["post-deployment"]}'

Then verify the results as described in Running a group of validations.

Access the Overcloud

openstack overcloud deploy generates an overcloudrc file appropriate for interacting with the deployed overcloud in the current user’s home directory. To use it, simply source the file:

source ~/overcloudrc

To return to working with the undercloud, source the stackrc file again:

source ~/stackrc

Setup the Overcloud network

Initial networks in Neutron in the overcloud need to be created for tenant instances. The following are example commands to create the initial networks. Edit the address ranges, or use the necessary neutron commands to match the environment appropriately. This assumes a dedicated interface or native VLAN:

openstack network create public --external --provider-network-type flat \
--provider-physical-network datacentre
openstack subnet create --allocation-pool start=,end= \
--network public --gateway --no-dhcp --subnet-range \ public

The example shows naming the network “public” because that will allow tempest tests to pass, based on the default floating pool name set in nova.conf. You can confirm that the network was created with:

openstack network list

Sample output of the command:

| ID                                   | Name     | Subnets                              |
| 4db8dd5d-fab5-4ea9-83e5-bdedbf3e9ee6 | public   | 7a315c5e-f8e2-495b-95e2-48af9442af01 |

To use a VLAN, the following example should work. Customize the address ranges and VLAN id based on the environment:

openstack network create public --external --provider-network-type vlan \
--provider-physical-network datacentre --provider-segment 195 \
openstack subnet create --allocation-pool start=,end= \
--network public --no-dhcp --gateway \
--subnet-range public

Validate the Overcloud

Source the overcloudrc file:

source ~/overcloudrc

Create a directory for Tempest (eg. naming it tempest):

mkdir ~/tempest
cd ~/tempest

Tempest expects the tests it discovers to be in the current working directory. Set it up accordingly:


The ~/tempest-deployer-input.conf file was created during deployment and contains deployment specific settings. Use that file to configure Tempest:

tools/ --deployer-input ~/tempest-deployer-input.conf \
                        --debug --create \
                        identity.uri $OS_AUTH_URL \
                        identity.admin_password $OS_PASSWORD

Run Tempest:



The full Tempest test suite might take hours to run on a single CPU.

Redeploy the Overcloud

The overcloud can be redeployed when desired.

  1. First, delete any existing Overcloud:

    heat stack-delete overcloud
  2. Confirm the Overcloud has deleted. It may take a few minutes to delete:

    # This command should show no stack once the Delete has completed
    heat stack-list
  3. It is recommended that you delete existing partitions from all nodes before redeploying. Starting with TripleO Ocata, you can use existing workflows - see Cleaning Nodes for details.

  4. Deploy the Overcloud again:

    openstack overcloud deploy --templates
