Bifrost supports different operating systems such as + Ubuntu, CentOS, and openSUSE. + More information about this project can be seen on + `Bifrost documentation `_. + +- **openstack/openstack-ansible:** OpenStack-Ansible is an official OpenStack + project which aims to deploy production environments from source in a way + that makes it scalable while also being simple to operate, upgrade, and grow. + More information about this project can be seen on + `OpenStack Ansible documentation `_. + +- **opnfv/releng:** OPNFV Releng Project provides additional scripts, Ansible + playbooks and configuration options in order for developers to have easy + way of using openstack/bifrost and openstack/openstack-ansible by just + setting couple of environment variables and executing a single script. + More infromation about this project can be seen on + `OPNFV Releng documentation _`. + +========== +Basic Flow +========== + +Here are the steps that take place upon the execution of the sandbox script +``xci-deploy.sh``: + +1. Sources environment variables in order to set things up properly. +2. Installs ansible on the host where sandbox script is executed. +3. Creates and provisions VM nodes based on the flavor chosen by the user. +4. Configures the host where the sandbox script is executed. +5. Configures the deployment host which the OpenStack installation will + be driven from. +6. Configures the target hosts where OpenStack will be installed. +7. Configures the target hosts as controller(s) and compute(s) nodes. +8. Starts the OpenStack installation. + +===================== +Sandbox Prerequisites +===================== + +In order to use this sandbox, the host must have certain packages installed. + +- libvirt +- python +- pip +- git +- +- passwordless sudo + +The host must also have enough CPU/RAM/Disk in order to host number of VM +nodes that will be created based on the chosen flavor. See the details from +`this link `_. + +=========================== +Flavors Provided by Sandbox +=========================== + +OPNFV XCI Sandbox provides different flavors such as all in one (aio) which +puts much lower requirements on the host machine and full-blown HA. + +* aio: Single node which acts as the deployment host, controller and compute. +* mini: One deployment host, 1 controller node and 1 compute node. +* noha: One deployment host, 1 controller node and 2 compute nodes. +* ha: One deployment host, 3 controller nodes and 2 compute nodes. + +See the details of the flavors from +`this link `_. + +========== +How to Use +========== + +Basic Usage +----------- + +clone OPNFV Releng repository + + git clone https://gerrit.opnfv.org/gerrit/releng.git + +change into directory where the sandbox script is located + + cd releng/prototypes/xci + +execute sandbox script + + sudo -E ./xci-deploy.sh + +Issuing above command will start aio sandbox deployment and the sandbox +should be ready between 1,5 and 2 hours depending on the host machine. + +Advanced Usage +-------------- + +The flavor to deploy, the versions of upstream components to use can +be configured by developers by setting certain environment variables. +Below example deploys noha flavor using the latest of openstack-ansible +master branch and stores logs in different location than what is configured. + +clone OPNFV Releng repository + + git clone https://gerrit.opnfv.org/gerrit/releng.git + +change into directory where the sandbox script is located + + cd releng/prototypes/xci + +set the sandbox flavor + + export XCI_FLAVOR=noha + +set the version to use for openstack-ansible + + export OPENSTACK_OSA_VERSION=master + +set where the logs should be stored + + export LOG_PATH=/home/jenkins/xcilogs + +execute sandbox script + + sudo -E ./xci-deploy.sh + +Warning:: + + Please encure you always execute the sandbox script using **sudo -E** + in order to make the environment variables you set available to the + sandbox script or you end up with the default settings. + +=============== +User Variables +=============== + +All user variables can be set from command line by exporting them before +executing the script. The current user variables can be seen from +``releng/prototypes/xci/config/user-vars``. + +The variables can also be set directly within the file before executing +the sandbox script. + +=============== +Pinned Versions +=============== + +As explained above, the users can pick and choose which versions to use. If +you want to be on the safe side, you can use the pinned versions the sandbox +provides. They can be seen from ``releng/prototypes/xci/config/pinned-versions``. + +How Pinned Versions are Determined +---------------------------------- + +OPNFV runs periodic jobs against upstream projects openstack/bifrost and +openstack/ansible using latest on master and stable/ocata branches, +continuously chasing the HEAD of corresponding branches. + +Once a working version is identified, the versions of the upstream components +are then bumped in releng repo. + +=========================================== +Limitations, Known Issues, and Improvements +=========================================== + +The list can be seen using `this link `_. + +========= +Changelog +========= + +Changelog can be seen using `this link `_. + +======= +Testing +======= + +Sandbox is continuously tested by OPNFV CI to ensure the changes do not impact +users. In fact, OPNFV CI itself uses the sandbox scripts to run daily platform +verification jobs. + +======= +Support +======= + +OPNFV XCI issues are tracked on OPNFV JIRA Releng project. If you encounter +and issue or identify a bug, please submit an issue to JIRA using +`this link _`. + +If you have questions or comments, you can ask them on ``#opnfv-pharos`` IRC +channel on Freenode. diff --git a/prototypes/xci/xci-deploy.sh b/prototypes/xci/xci-deploy.sh index c5cfab36d..7eb3ecdff 100755 --- a/prototypes/xci/xci-deploy.sh +++ b/prototypes/xci/xci-deploy.sh @@ -2,30 +2,42 @@ set -o errexit set -o nounset set -o pipefail -set -o xtrace +#------------------------------------------------------------------------------- # This script must run as root +#------------------------------------------------------------------------------- if [[ $(whoami) != "root" ]]; then echo "Error: This script must be run as root!" exit 1 fi +#------------------------------------------------------------------------------- +# Set environment variables +#------------------------------------------------------------------------------- +# The order of sourcing the variable files is significant so please do not +# change it or things might stop working. +# - user-vars: variables that can be configured or overriden by user. +# - pinned-versions: versions to checkout.
