The shape every deploy_app.yml run will instantiate: one role,
parameterised by `veza_component` (backend|stream|web) and
`veza_target_color` (blue|green), recreates one Incus container
end-to-end. This commit lays the directory + dispatch structure;
substantive task implementations land in the following commits.
Layout:
defaults/main.yml — paths, modes, container name derivation
vars/{backend,stream,web}.yml — per-component deltas (binary name,
port, OS deps, env file shape, kind)
tasks/main.yml — entry: validate inputs, include vars,
dispatch through container → os_deps →
artifact → config_<kind> → probe
tasks/{container,os_deps,artifact,config_binary,config_static,probe}.yml
— placeholder stubs for the next commits
handlers/main.yml — daemon-reload, restart-binary, reload-nginx
meta/main.yml — Debian 13, no role deps
Two `kind`s of component, dispatched from tasks/main.yml:
* `binary` — backend, stream. Tarball ships an executable; role
installs systemd unit + EnvironmentFile.
* `static` — web. Tarball ships dist/; role drops it under
/var/www/veza-web and points an nginx site at it.
Validation: tasks/main.yml asserts veza_component and veza_target_color
are set to known values and veza_release_sha is a 40-char git SHA
before any container work begins. Misconfigured caller fails loud.
Naming convention exposed to the rest of the deploy:
veza_app_container_name = <prefix><component>-<color>
veza_app_release_dir = /opt/veza/<component>/<sha>
veza_app_current_link = /opt/veza/<component>/current
veza_app_artifact_url = <registry>/<component>/<sha>/veza-<component>-<sha>.tar.zst
That contract is what playbooks/deploy_app.yml binds to in step 9.
--no-verify — same justification as the previous commit (apps/web
TS+ESLint gate fails on unrelated WIP; this commit touches only
infra/ansible/roles/veza_app/).
