Deploys a TripleO undercloud
Setup an Undercloud¶
--version: TripleO release to install.
Accepts either an integer for RHEL-OSP release, or a community release name (
Newton, etc…) for RDO release
--build: Specify a build date or a label for the repositories.
Supports any rhos-release labels. Examples:
GANot used in case of RDO.
--buildmods: Let you the option to add flags to rhos-release:
pin- Pin puddle (dereference ‘latest’ links to prevent content from changing). This flad is selected by default
flea- Enable flea repos.
unstable- This will enable brew repos or poodles (in old releases).
none- Use none of those flags.
--buildflags are internal Red Hat users only.
--enable-testing-repos: Let you the option to enable testing/pending repos with rhos-release. Multiple values
have to be coma separated. Examples:
--cdnRegister the undercloud with a Red Hat Subscription Management platform.
Accepts a file with subscription details.
server_hostname: example.redhat.com username: user password: HIDDEN_PASS autosubscribe: yes server_insecure: yes
For the full list of supported input, see the module documentation.
Pre-registered undercloud are also supported if
--cdnflag is missing.
The contents of the file are hidden from the logged output, to protect private account credentials.
--from-sourceBuild tripleo components from the upstream git repository.
Accepts list of tripleo components. The delorean project is used to build rpm packages. For more information about delorean, visit Delorean documentation.
To deploy specific tripleo components from git repository:
infrared tripleo-undercloud --version 13 \ --from-source name=openstack/python-tripleoclient \ --from-source name=openstack/neutron,refs=refs/changes/REF_ID \ --from-source name=openstack/puppet-neutron
- This feature is supported by OSP 13 or RDO queens versions.
- This feature is expiremental and should be used only for development.
To deploy a working undercloud:
infrared tripleo-undercloud --version 10
For better fine-tuning of packages, see custom repositories.
The final part of the undercloud installation calls for creating the images from which the OverCloud will be later created.
--images-taskthese the undercloud can be either:
Build the overcloud images from a fresh guest image. To use a different image than the default CentOS cloud guest image, use
--images-urlto define base image than CentOS. For OSP installation, you must provide a url of a valid RHEL image.
importimages from url:
Download pre-built images from a given
- Download images via
Starting from OSP 8, TripleO is packages with pre-built images avialable via RPM.
To use different RPM, use
--images-urlto define the location of the RPM. You need to provide all dependencies of the remote RPM. Locations have to be separated with comma
This option is invalid for RDO installation.
- Download images via
--images-packagesto define a list of additional packages to install on the OverCloud image. Packages can be specified by name or by providing direct url to the rpm file.
--images-cleanuptells infrared do remove the images files original after they are uploaded to the undercloud’s Glance service.
To configure overcloud images:
infrared tripleo-undercloud --images-task rpm
This assumes an undercloud was already installed and
will skip installation stage
--version is missing.
When using RDO (or for OSP 7),
rpm strategy in unavailable. Use
--images-url to download
overcloud images from web:
infrared tripleo-undercloud --images-task import --images-url http://buildlogs.centos.org/centos/7/cloud/x86_64/tripleo_images/mitaka/delorean
The RDO overcloud images can be also found here: https://images.rdoproject.org
If pre-packaged images are unavailable, tripleo can build the images locally on top of a regular cloud guest image:
infrared tripleo-undercloud --images-task build
CentOS or RHEL guest images will be used for RDO and OSP respectively.
To use a different image specify
infrared tripleo-undercloud --images-task build --images-url http://cloud.centos.org/centos/7/images/CentOS-7-x86_64-GenericCloud.qcow2
building the images takes a long time and it’s usually quicker to download them.
See the RDO deployment page for more details on how to setup RDO product.
Undercloud is configured according to
--config-file to provide this file, or let infrared generate one automatically, based on
a sample file provided by the project.
--config-options to provide a list of
section.option=value that will override
specific fields in it.
--ssl=yes option to install enable SSL on the undercloud. If used, a self-signed SSL cert will be generated.
Add custom repositories to the undercloud, after installing the TripleO repositories.
--repos-configsetup repos using the ansible yum_repository module.
Using this option enables you to set specific options for each repository:
--- extra_repos: - name: my_repo1 file: my_repo1.file description: my repo1 base_url: http://myurl.com/my_repo1 enabled: 0 gpg_check: 0 - name: my_repo2 file: my_repo2.file description: my repo2 base_url: http://myurl.com/my_repo2 enabled: 0 gpg_check: 0 ...
This expicitly supports some of the options found in yum_repository module (name, file, description, base_url, enabled and gpg_check). For more information about this module, visit Ansible yum_repository documentation.
repos-urls: comma separated list of URLs to download repo files to
Both options can be used together:
infrared tripleo-undercloud [...] --repos-config repos_config.yml --repos-urls "http://yoururl.com/repofile1.repo,http://yoururl.com/repofile2.repo"
TripleO Undercloud User¶
--user-password define a user, with password,
for the undercloud. Acorrding to TripleO guidelines, the default username is
User will be created if necessary.
When working on a virtual environment, infrared can create a snapshot of the installed undercloud that can be later used to restore it on a future run, thus saving installation time.
In order to use this feature, first follow the Setup an Undercloud section. Once an undercloud VM is up and ready, run the following:
ir tripleo-undercloud --quickstart-backup yes
Or optionally, provide the file name of the image to create (defaults to “undercloud-quickstart.qcow2”). .. note:: the filename refers to a path on the hypervisor.
ir tripleo-undercloud –quickstart-backup yes –quickstart-filename custom-name.qcow2
This will prepare a qcow2 image of your undercloud ready for usage with Restore.
When working on a virtual environment, infrared can use a pre-made undercloud image to quickly set up an environment. To use this feature, simply run:
ir tripleo-undercloud --quickstart-restore yes
Or optionally, provide the file name of the image to restore from (defaults to “undercloud-quickstart.qcow2”). .. note:: the filename refers to a path on the hypervisor.
Upgrade is discovering current Undercloud version and upgrade it to the next major one. To upgrade Undercloud run the following command:
infrared tripleo-undercloud -v --upgrade yes
The Overcloud won’t need new images to upgrade to. But you’d need to upgrade the images for OC nodes before you attempt to scale out nodes. Example for Undercloud upgrade and images update:
infrared tripleo-undercloud -v --upgrade yes --images-task rpm
Currently, there is upgrade possibility from version 9 to version 10 only.
Upgrading from version 11 to version 12 isn’t supported via the tripleo-undercloud plugin anymore. Please check the tripleo-upgrade plugin for 11 to 12 upgrade instructions.
Update is discovering current Undercloud version and perform minor version update. To update Undercloud run the following command:
infrared tripleo-undercloud -v --update-undercloud yes
Example for update of Undercloud and Images:
infrared tripleo-undercloud -v --update-undercloud yes --images-task rpm
Infrared support update for RHOSP from version 8.
Setup TLS Everywhere with FreeIPA.
tls-everywhere: It will install FreeIPA on first node from freeipa group and it will configure undercloud for TLS Everywhere.
