Sync Kolla Inventory

Sync Kolla Inventory

When to Use

• Preparing Kayobe for a new Kolla Ansible release
• Syncing inventory changes from kolla-ansible multinode inventory
• Verifying new/removed inventory groups are reflected in the correct Kayobe template

Last validated for 2026.1.

Source and Targets

• Source inventory in kolla-ansible:
  • ansible/inventory/multinode
• Kayobe targets:
  • ansible/roles/kolla-ansible/templates/overcloud-top-level.j2
  • ansible/roles/kolla-ansible/templates/overcloud-components.j2
  • ansible/roles/kolla-ansible/templates/overcloud-services.j2

Kayobe splits multinode inventory into three parts.

Boundary Rules

Top level

Target: ansible/roles/kolla-ansible/templates/overcloud-top-level.j2

• This file is heavily templated and does not typically need changes.
• Look for changes in multinode before the [baremetal] group.
• If there are changes in that region, port them carefully while preserving existing Kayobe templating.

Components

Target: ansible/roles/kolla-ansible/templates/overcloud-components.j2

• Includes multinode groups from [baremetal] down to this marker:

# Additional control implemented here. These groups allow you to control which
# services run on which hosts at a per-service level.

• This file maps components to top-level groups.

Services

Target: ansible/roles/kolla-ansible/templates/overcloud-services.j2

• Includes multinode groups from the marker above to end of file.
• This file maps service containers to components.
• Keep Kayobe-specific small changes in this section unless intentionally removed.

Procedure

1. Get the source inventory snapshot

Prompt for the target <release> (for example 2026.1), then ensure the kolla-ansible checkout exists under ${KAYOBE_AGENT_WORKDIR} in kolla-ansible/.

Before cloning or reusing the checkout, source .agents/scripts/agent-environment.sh to set KAYOBE_AGENT_WORKDIR.

If kolla-ansible/ does not exist, clone with:

source .agents/scripts/agent-environment.sh
git clone https://github.com/openstack/kolla-ansible -b stable/<release> "${KAYOBE_AGENT_WORKDIR}/kolla-ansible"

If kolla-ansible/ already exists, checkout the correct branch:

source .agents/scripts/agent-environment.sh
git -C "${KAYOBE_AGENT_WORKDIR}/kolla-ansible" status --porcelain

If this command returns any output, stop and ask the user to clean, commit, or stash changes before continuing. Abort all sync checks until the checkout is clean.

Then run:

source .agents/scripts/agent-environment.sh
git -C "${KAYOBE_AGENT_WORKDIR}/kolla-ansible" fetch origin
git -C "${KAYOBE_AGENT_WORKDIR}/kolla-ansible" checkout stable/<release>
git -C "${KAYOBE_AGENT_WORKDIR}/kolla-ansible" pull --ff-only origin stable/<release>

2. Compare multinode against Kayobe split templates

Review group additions/removals/renames in the source and map each change by section boundary:

• Before [baremetal] -> overcloud-top-level.j2
• [baremetal] to marker -> overcloud-components.j2
• Marker to end -> overcloud-services.j2

3. Apply updates to the correct Kayobe template

Port each relevant change into the appropriate file while preserving existing Kayobe templating and comments.

4. Validate new services are placed correctly

When new services appear in multinode:

• Add top-level component groups to overcloud-components.j2 when appropriate.
• Add per-service container groups to overcloud-services.j2.
• Sub-services/exporters of an existing component generally belong in overcloud-services.j2 only.

5. Re-check Kayobe-specific behavior

After sync, confirm intentional Kayobe differences are still present and valid, particularly in overcloud-services.j2.

Checklist

• Prompted for target <release>
• Ensured kolla-ansible/ exists in repo root on stable/<release>
• Confirmed kolla-ansible/ has no uncommitted changes before checkout
• Aborted all sync checks if kolla-ansible/ was dirty
• Compared kolla-ansible ansible/inventory/multinode with Kayobe templates
• Reviewed pre-[baremetal] changes for overcloud-top-level.j2
• Synced component groups into overcloud-components.j2
• Synced service groups into overcloud-services.j2
• Verified new services are in the correct file(s)
• Preserved intentional Kayobe-specific service-section changes
