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.

Manifest

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

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/.

Available samples:

• postgresql-18: single PostgreSQL 18 container with a named data volume.
• valkey-9: cache container backed by a Quadlet volume.
• rustfs: S3-compatible object storage on a Quadlet network and volume.
• keycloak: multi-container Keycloak and PostgreSQL service on a shared network.
• app-pod: Podman pod with web and sidecar containers.
• local-api-build: local image build consumed by a container Quadlet.

dew infra validate postgresql-18
dew infra up postgresql-18
