undercloud-deploy

An Ansible role to execute the deployment of the tripleo undercloud

Requirements

This requires a running host to deploy the undercloud.

Role Variables

• undercloud_templates_path: <'/usr/share/openstack-tripleo-heat-templates'> -- a path to git clone and check-out t-h-t templates from the corresponding repo/branch/ref paths.
• undercloud_config_file: <'undercloud.conf.j2'> -- the name of the jinja template used as the base for the undercloud.conf
• undercloud_install_script: <'undercloud-install.j2'> -- the name of the jinja template used as the base for the undercloud-install bash script and dev envs hacking. Note, the defaults imply the 'openstack undercloud install' command will be invoked. See the undercloud deployment methods section below for the alternative modes.
• undercloud_install_log: <'{{ working_dir }}/undercloud_install.log'> -- the full path to the undercloud install log file.
• undercloud_hieradata_override_file: <'hieradata-overrides-classic-undercloud.yaml.j2'> -- the name of jinja template used to override the undercloud's install hieradata. DEPRECATED. Use instead:
• hieradata_override_file_classic_undercloud: <hieradata-overrides-classic-undercloud.yaml.j2> -- the source template for hieradata overrides for instack-undercloud deployments.
• hieradata_override_file_t_h_t_undercloud: <hieradata-overrides-t-h-t-undercloud.yaml.j2> -- the source template for hieradata overrides for heat driven containerized undercloud deployments.
• undercloud_ironic_ipxe_port: <'3816'> -- port to use for httpd ipxe server for ironic deploy
• enable_vbmc: <'true'> use a virtual bmc instead of pxe ssh
• step_introspect: <'false'> -- boolean value to enable/disable ironic introspection
• bash_deploy_ramdisk: <'false'> -- the variable allows older versions of tripleo to upload images properly with the option --old-deploy-image
• step_install_undercloud: <'true'> -- turn on/off the undercloud deployment
• libvirt_uri: <'qemu:///session'> -- the URI used by libvirt, by default tripleo-quickstart uses user sessions to provide greater flexixiblity to our users. ** additional documentation ** is at https://docs.openstack.org/tripleo-quickstart/latest/accessing-libvirt.html
• undercloud_conf_extra: <''> -- extra options to be added to ~/undercloud.conf
• undercloud_extra_args: <''> -- extra options for undercloud deploy command.
• undercloud_install_cmd: <'openstack undercloud install'> -- command used to install the undercloud
• undercloud_install_cli_options: <''> -- extra options for undercloud install command.
• undercloud_enable_mistral: <'true'> -- sets up the 'enable_mistral' option in undercloud.conf.
• undercloud_enable_monitoring: <'false'> -- sets up the 'enable_monitoring' option in undercloud.conf.
• undercloud_enable_telemetry: <'true'> -- sets up the 'enable_telemetry' option in undercloud.conf.
• undercloud_enable_tempest: <'true'> -- sets up the 'enable_tempest' option in undercloud.conf.
• undercloud_enable_ui: <'true'> -- sets up the 'enable_ui' option in undercloud.conf.
• undercloud_enable_validations: <'true'> -- sets up the 'enable_validations' option in undercloud.conf.
• undercloud_enable_novajoin: <'false'> -- sets up the 'enable_novajoin' value from undercloud.conf. Note that using 'enable_tls_everywhere' will have the same effect.
• novajoin_connect_timeout: <5> Sets vendordata_dynamic_connect_timeout when novajoin is enabled
• novajoin_read_timeout: <20> Sets vendordata_dynamic_read_timeout when novajoin is enabled
• prepare_novajoin: If set to true, it will install novajoin in the undercloud, and run a script that will create the required privileges/permissions in FreeIPA, as well as the undercloud host entry. this requires 'enable_tls_everywhere' to be set to true, and the following variables to be properly defined: 'freeipa_admin_password', 'freeipa_server_hostname', 'overcloud_cloud_domain', 'undercloud_undercloud_hostname'. If you plan to do this yourself, you can set this variable to false. Defaults to true.
• freeipa_admin_password: The password for the admin principal for FreeIPA. This will be used to run the script to prepare FreeIPA for novajoin.
• freeipa_server_hostname: The hostname for the FreeIPA server. This will be used to run the script to prepare FreeIPA for novajoin.
• overcloud_cloud_domain: The domain configured for use by the overcloud nodes. If TLS everywhere is enabled, this will also be the domain used by FreeIPA. This sets up the 'overcloud_domain_name' configuration option in undercloud.conf . Note: This also affects CloudDomain in the cloud-names.yaml template used by the overcloud-deploy role.
• undercloud_cloud_domain: The domain configured for use by containerized undercloud via the tripleo client's --local-domain option. It is unset by default.
• tripleo_ui_secure_access: Defaults to false due to the self signed certificate and usability issues. See the tripleo-quickstart documentation accessing the undercloud for details.
• local_docker_registry_host: <docker_registry_host> -- registry host/port for containerized undercloud services. Defaults to the value provided for overcloud. You may want to diverge it, if building locally, or fetching from remote registries not fitting the overcloud deployment needs.
• undercloud_container_images_file: <""> -- The environment file with default parameters for containers to use with undercloud install CLI. This should only be used to override image prepare generating this during the undercloud install.
• undercloud_custom_env_files: -- A space-separate string for custom t-h-t env files for undercloud.conf used with heat installer.
• undercloud_undercloud_output_dir: -- allows customize output directory for state, like downloaded ansible configs and processed heat templates for heat installer
• undercloud_undercloud_cleanup: -- controls tear down of the processed heat templates
• undercloud_upgrade_cleanup: -- controls post upgrade cleanup after we containerize the undercloud.
• update_containers: -- whether to update containers from the local registry.
• undercloud_enable_tempest: -- The tempest container will be available on the undercloud.
• undercloud_roles_data: -- A custom t-h-t roles file. Consumed from undercloud_templates_path or an alternative location as well.
• undercloud_selinux_enabled: <'true'> -- Enabled for RHEL by default, Disabled for CentOS by default
• undercloud_enable_paunch: -- Enable or disable Paunch to manage containers. Undefined by default.
• undercloud_container_cli: <'podman'> -- Container CLI to use for the Undercloud deployment. Default to 'podman'.

Role Network Variables

• undercloud_network_cidr: <'192.168.24.0/24'> -- the network cidr for the undercloud, note this also currently the default cidr used in other CI environments for tripleo.
• undercloud_network_gateway: <a 1st host of the undercloud_network_cidr> -- Sets up the undercloud_network_gateway parameter from undercloud.conf.
• undercloud_local_ip: <hostvars['undercloud'].undercloud_ip> -- Sets up the local_ip parameter from an inventory. Must be belonging to the undercloud_network_cidr. It is used by overcloud nodes to access the undercloud node via a routable [ctlplane network]((https://docs.openstack.org/developer/tripleo-docs/advanced_deployment/network_isolation). Note that the undercloud.conf takes the default value based on the undercloud_network_cidr instead.
• undercloud_undercloud_public_host: <a 2nd host of the undercloud_network_cidr> -- Sets up the 'undercloud_public_host' parameter from undercloud.conf. It is also used by overcloud nodes to access the undercloud node via a VIP/hostname that resolves to a routable IP address.
• undercloud_undercloud_admin_host: <a 3rd host of the undercloud_network_cidr> -- Sets up the 'undercloud_admin_host' from undercloud.conf. Note, use the undercloud_admin_vip instead for Mitaka/Newton releases.
• undercloud_dhcp_start: <a 5th host of the undercloud_network_cidr> -- Sets up the 'undercloud_dhcp_start' from undercloud.conf.
• undercloud_dhcp_end: <a 30th host of the undercloud_network_cidr> -- Sets up the 'undercloud_dhcp_end' from undercloud.conf.
• undercloud_undercloud_nameservers: <['8.8.8.8']> -- Sets up the 'undercloud_undercloud_nameservers' from undercloud.conf. May be a string or a sequence. Only the last item goes for the undercloud deploy command.
• undercloud_undercloud_hostname: Sets up the 'undercloud_hostname' value from undercloud.conf. Note, use the undercloud_public_vip instead for Mitaka/Newton releases.
• undercloud_heat_public_endpoints: <'false'> -- when the ctlplane network is not routable from overcloud nodes, for example pre-provisioned deployed servers, the undercloud deploy --local_ip (and local_ip in the undercloud.conf) may not be used. Enable this variable instead. Doing so changes the heat endpoint type from the default internal to public and changes the signaling method to use TempURLs from OpenStack Object Storage (swift).
• undercloud_resource_registry_args: Complements 'resource_registry' for undercloud heat templates. Defaults to nothing.
• undercloud_network_environment_args: Complements Undercloud networking setup with the default parameters for heat templates (parameter_defaults).
• undercloud_net_config_override: -- a j2 template for os-net-config used to override network configuration, which is normally defined via 'OS::TripleO::Undercloud::Net::SoftwareConfig'. Accepts instack tags like LOCAL_IP et al. When it is defined, the undercloud_resource_registry_args value will be discarded.

Undercloud deployment methods

The undercloud uses openstack undercloud install command, {{working_dir}}/undercloud.conf config and the file coming from the hieradata_override_file_classic_undercloud variable to set the hieradata overrides that will be used for the puppet deployment. Alternatively there is a heat yaml way to provide overrides as well. For these cases, hiera override data is consumed from hieradata_override_file_t_h_t_undercloud.
