tripleo-upgrade

This role aims to provide a unified tool for upgrading TripleO based deploments.

Requirements

This role requires:

• An ansible inventory file containing reacheable undercloud and overcloud nodes

• Nodes in the inventory file are placed in groups based on their roles (e.g compute nodes are part of the 'compute' group)

• Repositories containing packages to be upgraded are already installed on undercloud and overcloud nodes (or, for overcloud, define an upgrade_init_command variable)

• The initial overcloud deploy command is placed in a script file located in the path set by the overcloud_deploy_script var. Each option/environment file should be placed on a separate new line, e.g:

  source ~/stackrc
  export THT=/usr/share/openstack-tripleo-heat-templates/
  
  openstack overcloud deploy --templates $THT \
  -r ~/openstack_deployment/roles/roles_data.yaml \
  -e $THT/environments/network-isolation.yaml \
  -e $THT/environments/network-management.yaml \
  -e $THT/environments/storage-environment.yaml \
  -e ~/openstack_deployment/environments/nodes.yaml \
  -e ~/openstack_deployment/environments/network-environment.yaml \
  -e ~/openstack_deployment/environments/disk-layout.yaml \
  -e ~/openstack_deployment/environments/neutron-settings.yaml \
  --log-file overcloud_deployment.log &> overcloud_install.log

upgrade_workarounds: false

Allows the user to apply known issues workarounds during the upgrade process. The list of patches/commands used for workarounds should be passed via --extra-vars and it should include dictionaries for undercloud/overcloud workarounds:

use_oooq: false

Set to true when the deployment has been done by tripleo quickstart:

workload_launch: false

Set to true to launch an instance before starting upgrade. This can be useful for running tests during upgrade such as live migration or floating IP connectivity checks:

workload_cleanup: false

Set to true to cleanup previously launched workload when update/upgrade finishes:

external_network_name: "public"

Name of the external network providing floating IPs for instance connectivity. This provides external connectivity and needs to exist beforehand, created by the user:

workload_image_url: "https://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img"

URL of the image used for the workload instance:

workload_memory: "512"

Amount of memory assigned for the workload instance:

workload_sriov: false

Set to true to use an SRIOV PF port when workload is created. Notice this will not work with cirros images:

tripleo_ci: false

Set to true when running the role in the TripleO CI jobs. It avoids losing connectivity to the undercloud by skipping reboot and ssh kill tasks:

upgrade_init_command: |
    sudo tripleo-repos -b pike current

Bash commands, defines a custom upgrade init to be taken into account during overcloud upgrade.

update_cell: false

Set it to true to get a multi-cell update. It changes the way the oc_roles_hosts is calculated.

l3_agent_connectivity_check: false

When set to true add a vm with attached fip and monitor ping from the undercloud. If ping loss time is higher than loss_threshold seconds or loss_threshold_percent in percentage we fail.

update_loss_threshold: 0

For update run tasks we set a 0 seconds loss threshold by default.

loss_threshold: 60

Default time is second for ping loss.

loss_threshold_percent: 1

Failsafe percentage check for loss threashold in percentage

Dependencies

None.

Example Playbook

An example playbook is provided in tests/test.yml:

- hosts: undercloud
  gather_facts: true
  become: true
  become_method: sudo
  become_user: stack
  roles:
    - tripleo-upgrade

Usage with tripleo Quickstart

After a successful deployment with OOOQ, you can create the necessary scripts using this example playbook (duplicate from ./tests/oooq-test.yaml):

---
- hosts: undercloud
  gather_facts: true
  become: true
  become_method: sudo
  become_user: stack
  roles:
  - { role: tripleo-upgrade, use_oooq: 'true'}

And then you run it like this (adjust the paths to your oooq specific one):

ANSIBLE_SSH_ARGS="-F $(pwd)/ssh.config.ansible" \
  ANSIBLE_CONFIG=$PWD/ansible.cfg \
  ansible-playbook -i hosts -vvv tripleo-upgrade/tests/oooq-test.yaml

This will only create the file (without running the actual upgrade):

• undercloud_upgrade.sh
• composable_docker_upgrade.sh
• overcloud-compute-*_upgrade_pre.sh
• overcloud-compute-*_upgrade.sh
• overcloud-compute-*_upgrade_post.sh
• converge_docker_upgrade.sh

with the correct parameters.

Usage with InfraRed

tripleo-upgrade comes preinstalled as an InfraRed plugin. In order to install it manually, the following InfraRed command should be used:

infrared plugin add tripleo-upgrade
# add with a specific revision / branch
infrared plugin add --revision stable/rocky tripleo-upgrade

After a successful InfraRed overcloud deployment you need to run the following steps to upgrade the deployment:

Symlink roles path:

ln -s $(pwd)/plugins $(pwd)/plugins/tripleo-upgrade/infrared_plugin/roles

Set up undercloud upgrade repositories:

infrared tripleo-undercloud \
    --upgrade yes \
    --mirror ${mirror_location} \
    --ansible-args="tags=upgrade_repos"

Set up undercloud update repositories:

infrared tripleo-undercloud \
    --update-undercloud yes \
    --mirror ${mirror_location} \
    --build latest \
    --version 12 \
    --ansible-args="tags=upgrade_repos"

Upgrade undercloud:

infrared tripleo-upgrade \
    --undercloud-upgrade yes

Update undercloud:

infrared tripleo-upgrade \
    --undercloud-update yes

Set up overcloud upgrade repositories:

infrared tripleo-overcloud \
    --deployment-files virt \
    --upgrade yes \
    --mirror ${mirror_location} \
    --ansible-args="tags=upgrade_collect_info,upgrade_repos"

Set up overcloud update repositories/containers:

infrared tripleo-overcloud \
    --deployment-files virt \
    --ocupdate True \
    --build latest \
    --ansible-args="tags=update_collect_info,update_undercloud_validation,update_repos,update_prepare_containers"

Upgrade overcloud:

infrared tripleo-upgrade \
    --overcloud-upgrade yes

Update overcloud:

infrared tripleo-upgrade \
    --overcloud-update yes

Advanced upgrade options

Operator can now specify order of roles to upgrade by using roles_upgrade_order variable.

It's the responsibility of operator to specify Controller role first followed by all other roles.

roles_upgrade_order variable expects roles being separated by ;(semicolon), for e.g.:

infrared tripleo-upgrade \
    --overcloud-upgrade yes \
    -e 'roles_upgrade_order=ControllerOpenstack;Database;Messaging'

will upgrade ControllerOpenstack group, then Database and finally Messaging.

Multiple roles could be upgraded in parallel, to achieve this they should be separated by ,(comma), for e.g:

infrared tripleo-upgrade \
    --overcloud-upgrade yes \
    -e 'roles_upgrade_order=ControllerOpenstack;Database;Messaging'

will upgrade Controller and Database groups in parallel and then continue with Messaging.

Running the role manually from the undercloud

This role can be run manually from the undercloud by doing the following steps:

Note: before starting the upgrade process make sure that both the undercloud and overcloud nodes have the repositories with upgraded packages set up

Clone this repository

git clone https://opendev.org/openstack/tripleo-upgrade

Set ansible roles path::

ANSIBLE_ROLES_PATH=$(pwd)

Create inventory file::

printf "[undercloud]nlocalhost ansible_connection=local" > hosts

Run the playbook including this role::

ansible-playbook -i hosts tripleo-upgrade/tests/test.yml
