# Fleet operator — release & deploy
How the operator ships: build + publish a versioned image and helm
chart, then `harmony apply` (a plain `helm upgrade --install` of that
published chart). No Argo, no GitOps controller — Harmony owns the loop
(ADR-012-2). CD is **roll-forward only**: to back out a bad release,
deploy a previous good version.
## 1. Cut a release (automated on tag)
```sh
git tag harmony-fleet-operator-v0.0.2 && git push --tags
```
The `harmony-fleet-operator` workflow builds the image and the hydrated
helm chart and pushes both to `hub.nationtech.io` at `0.0.2`. No human
touches a Dockerfile, chart, or registry.
Laptop fallback (does exactly what the workflow's job does):
```sh
# docker + helm must be logged in to hub.nationtech.io first.
cargo run --release -p harmony-fleet-deploy --bin harmony-fleet-release -- \
--from-tag harmony-fleet-operator-v0.0.2
# build + package only, no push (local k3d smoke-test):
cargo run -p harmony-fleet-deploy --bin harmony-fleet-release -- \
--from-tag harmony-fleet-operator-v0.0.2 --no-push
```
## 2. Deploy a published version (`harmony apply`)
`--operator-chart-version` switches the operator to install the
published `oci://hub.nationtech.io/harmony/harmony-fleet-operator:0.0.2`
chart instead of rendering one from local source. Same command
bootstraps and upgrades; re-running with the same version is a no-op.
```sh
export HARMONY_FLEET_NATS_ADMIN_USER=HARMONY_FLEET_NATS_ADMIN_PASS=
export HARMONY_FLEET_NATS_DEVICE_USER=HARMONY_FLEET_NATS_DEVICE_PASS=
harmony-fleet-deploy \
--filter FleetOperatorScore \
--operator-chart-version 0.0.2 \
--namespace fleet-system \
--yes
```
## 3. Roll forward
Same command, a newer (or previous-good) version:
```sh
harmony-fleet-deploy --filter FleetOperatorScore --operator-chart-version 0.0.3 --namespace fleet-system --yes
```
`helm upgrade --install` applies it and fails loudly if convergence
fails — no automatic rollback. Fix the spec, bump, re-run.
## Automated vs. manual
| Step | Where |
|---|---|
| Build + push image + chart on tag | CI (`release` job) |
| Deploy a published version + roll forward | Manual `harmony apply` (above) |
A staging-auto / production-gated CD job is a follow-up — it needs the
cluster `KUBECONFIG` + NATS secrets provisioned, which is out of scope
for the initial CD branch (ADR-012-2). The release job is fully
functional today.
