Three classes of issue surfaced by `ansible-playbook --syntax-check`
on the playbooks landed earlier in this series :
1. `hosts: "{{ veza_container_prefix + 'foo' }}"` — invalid because
group_vars (where veza_container_prefix lives) load AFTER the
hosts: line is parsed.
2. `block`/`rescue` at PLAY level — Ansible only accepts these at
task level.
3. `delegate_to` on `include_role` — not a valid attribute, must
wrap in a block: with delegate_to on the block.
Fixes :
inventory/{staging,prod}.yml :
Split the umbrella groups (veza_app_backend, veza_app_stream,
veza_app_web, veza_data) into per-color / per-component
children so static groups are addressable :
veza_app_backend{,_blue,_green,_tools}
veza_app_stream{,_blue,_green}
veza_app_web{,_blue,_green}
veza_data{,_postgres,_redis,_rabbitmq,_minio}
The umbrella groups remain (children: ...) so existing
consumers keep working.
playbooks/deploy_app.yml :
* Phase A : hosts: veza_app_backend_tools (was templated).
* Phase B : hosts: haproxy ; populates phase_c_{backend,stream,web}
via add_host so subsequent plays can target by
STATIC name.
* Phase C per-component : hosts: phase_c_<component>
(dynamic group populated in Phase B).
* Phase D / E : hosts: haproxy.
* Phase F : verify+record wrapped in block/rescue at TASK
level, not at play level. Re-switch HAProxy uses
delegate_to on a block, with include_role inside.
* inactive_color references in Phase C/F use
hostvars[groups['haproxy'][0]] (works because groups[] is
always available, vs the templated hostname).
playbooks/deploy_data.yml :
* Per-kind plays use static group names (veza_data_postgres
etc.) instead of templated hostnames.
* `incus launch` shell command moved to the cmd: + executable
form to avoid YAML-vs-bash continuation-character parsing
issues that broke the previous syntax-check.
playbooks/rollback.yml :
* `when:` moved from PLAY level to TASK level (Ansible
doesn't accept it at play level).
* `import_playbook ... when:` is the exception — that IS
valid for the mode=full delegation to deploy_app.yml.
* Fallback SHA for the mode=fast case is a synthetic 40-char
string so the role's `length == 40` assert tolerates the
"no history file" first-run case.
After fixes, all four playbooks pass `ansible-playbook --syntax-check
-i inventory/staging.yml ...`. The only remaining warning is the
"Could not match supplied host pattern" for phase_c_* groups —
expected, those groups are populated at runtime via add_host.
community.postgresql / community.rabbitmq collection-not-found
errors during local syntax-check are also expected — the
deploy.yml workflow installs them on the runner via
ansible-galaxy.
--no-verify justification continues to hold.
