# Infrastructure
|
|
|
|
`dew infra` manages project-local infrastructure services declared under
|
|
`.project/infrastructure`.
|
|
|
|
The initial runtime backend is Podman Quadlets installed into systemd search
|
|
paths. The command surface is runtime-oriented rather than Podman-specific so
|
|
future backends can be added without changing project manifests or common CLI
|
|
workflows.
|
|
|
|
## Layout
|
|
|
|
```text
|
|
.project/infrastructure/
|
|
└── services/
|
|
└── postgres/
|
|
├── manifest.yaml
|
|
├── app_postgres.container
|
|
├── app_postgres.container.d/
|
|
├── app_postgres.profiles.d/
|
|
├── schemas/
|
|
│ ├── configure.schema.json
|
|
│ └── init.schema.json
|
|
└── config/
|
|
```
|
|
|
|
## Manifest
|
|
|
|
```yaml
|
|
id: postgres
|
|
name: PostgreSQL
|
|
|
|
runtime:
|
|
type: podman-quadlet
|
|
|
|
quadlets:
|
|
- file: app_postgres.container
|
|
unit: app_postgres.service
|
|
container_name: app_postgres
|
|
dropins_dir: app_postgres.container.d
|
|
profiles_dir: app_postgres.profiles.d
|
|
|
|
schemas:
|
|
configure: schemas/configure.schema.json
|
|
init: schemas/init.schema.json
|
|
```
|
|
|
|
The `quadlets` list can contain any supported Podman Quadlet source type:
|
|
`.artifact`, `.build`, `.container`, `.image`, `.kube`, `.network`, `.pod`, and
|
|
`.volume`. If `unit` is omitted, Dew derives the default generated systemd unit
|
|
from the Quadlet filename. Declare `unit` when the Quadlet file uses a
|
|
`ServiceName=` override.
|
|
|
|
The package-level schema for this file is
|
|
`packages/infra/schemas/service-manifest.schema.json`.
|
|
|
|
## Commands
|
|
|
|
```bash
|
|
dew infra list
|
|
dew infra show postgres
|
|
dew infra validate --all
|
|
dew infra configure postgres schema
|
|
dew infra configure postgres show
|
|
dew infra configure postgres apply --file config.json --set port=5432
|
|
dew infra init postgres schema
|
|
dew infra init postgres run --file init.json
|
|
dew infra install postgres
|
|
dew infra up postgres
|
|
dew infra status postgres
|
|
dew infra logs postgres --lines 200
|
|
dew infra down postgres
|
|
dew infra delete postgres --container
|
|
```
|
|
|
|
Use `--dry-run` on mutating commands to print filesystem, systemctl, journalctl,
|
|
and podman actions without applying them. Use `--scope user` for the default
|
|
user systemd path or `--scope system` for `/etc/containers/systemd`.
|
|
|
|
`dew infra up` installs missing Quadlet files, reloads systemd, then starts the
|
|
declared units.
|
|
|
|
## Samples
|
|
|
|
The Dew repository includes sample service bringups under
|
|
`.project/infrastructure/services/`.
|
|
|
|
`postgresql-18` brings up a local PostgreSQL 18 container through Podman
|
|
Quadlets:
|
|
|
|
```bash
|
|
dew infra validate postgresql-18
|
|
dew infra up postgresql-18
|
|
```
