Sealos Deploy

Compatibility

Sealos auth/workspace are required for deploys. Docker, buildx, and gh CLI are required only when the selected path needs local build/push. git is required when cloning from a GitHub URL or when git metadata is needed. Node.js 18+ and Python 3.8+ remain optional accelerators.

Deploy any GitHub project to Sealos Cloud — from source code to running application, one command.

kubectl Safety Rules (all phases)

All kubectl commands MUST use the Sealos kubeconfig:

KUBECONFIG=~/.sealos/kubeconfig kubectl --insecure-skip-tls-verify

System tool installation requires user confirmation. If docker, gh, or kubectl is missing and the skill can install it for the current platform, ask first and only run the install command after the user explicitly replies y.

kubectl delete requires user confirmation. Before deleting any resource (deployment, service, ingress, PVC, database, etc.), always ask:

WARNING: About to delete <resource kind>/<resource name>. This data cannot be recovered. Confirm? (y/n)

Only proceed after user confirms. This applies even if the pipeline logic suggests deletion — always ask first.

Template API cleanup must include Instance CRs. Deployments created through scripts/deploy-template.mjs create instances.app.sealos.io/<app-name> in addition to App/workload resources. A cleanup is incomplete until instances.app.sealos.io, apps.app.sealos.io, workloads, Services, Ingresses, PVCs, and Pods are all checked.

Use this check when cleaning Template API test deployments:

KUBECONFIG=~/.sealos/kubeconfig kubectl --insecure-skip-tls-verify -n "$NS" \
  get instances.app.sealos.io,app,statefulset,deployment,svc,ingress,pvc,pod | grep "$APP"

Delete in this order after confirmation:

KUBECONFIG=~/.sealos/kubeconfig kubectl --insecure-skip-tls-verify -n "$NS" delete instances.app.sealos.io "$APP" --ignore-not-found --wait=false
KUBECONFIG=~/.sealos/kubeconfig kubectl --insecure-skip-tls-verify -n "$NS" delete app "$APP" --ignore-not-found --wait=false
KUBECONFIG=~/.sealos/kubeconfig kubectl --insecure-skip-tls-verify -n "$NS" delete statefulset "$APP" --ignore-not-found --wait=false
KUBECONFIG=~/.sealos/kubeconfig kubectl --insecure-skip-tls-verify -n "$NS" delete deployment "$APP" --ignore-not-found --wait=false
KUBECONFIG=~/.sealos/kubeconfig kubectl --insecure-skip-tls-verify -n "$NS" delete ingress "$APP" --ignore-not-found --wait=false
KUBECONFIG=~/.sealos/kubeconfig kubectl --insecure-skip-tls-verify -n "$NS" delete svc "$APP" --ignore-not-found --wait=false
KUBECONFIG=~/.sealos/kubeconfig kubectl --insecure-skip-tls-verify -n "$NS" get pvc -o name | grep "$APP" | while read -r PVC; do
  KUBECONFIG=~/.sealos/kubeconfig kubectl --insecure-skip-tls-verify -n "$NS" delete "$PVC" --ignore-not-found --wait=false
done

Anti-example: do not report cleanup complete after only checking app,statefulset,svc,ingress,pvc,pod; that misses instances.app.sealos.io/<app-name> and leaves the Sealos Instance layer dirty.

Usage

/sealos-deploy <github-url>
/sealos-deploy                    # deploy current project
/sealos-deploy <local-path>

Quick Start

Execute the modules in order:

1. modules/preflight.md — Environment checks & Sealos auth
2. modules/pipeline.md — Full deployment pipeline (Phase 1–6)
3. modules/runtime-truth.md — Post-deploy Runtime Truth Pass (Phase 6.5)

Logging

Every run MUST write a log file at ~/.sealos/logs/deploy-<YYYYMMDD-HHmmss>.log.

At the very start of execution, create the log file once:

mkdir -p ~/.sealos/logs
LOG_FILE=~/.sealos/logs/deploy-$(date +%Y%m%d-%H%M%S).log
echo "[$(date '+%Y-%m-%d %H:%M:%S')] Deploy started" > "$LOG_FILE"

Important: create the log file ONLY ONCE at the start. All subsequent writes MUST append (>>) to this same $LOG_FILE. Do NOT create a second log file.

At each phase boundary, append a log entry to the same file with Bash >>:

build-push.mjs	node build-push.mjs <work-dir> <repo> [--registry ghcr|dockerhub] [--user <user>]	Build amd64 image & push to the selected registry (Docker Hub path assumes a public image at deploy time; omitting --registry keeps auto-detect behavior)

deploy-template.mjs	node deploy-template.mjs <template-path> [--dry-run] [--args-json '{"KEY":"value"}'|--args-file <file>]	Resolve the current region from ~/.sealos/auth.json, build the correct Template API URL, and post a local template YAML

sealos-live-smoke.mjs	node sealos-live-smoke.mjs --url <url> [--captcha-path <path>] [--login-method json-token|cookie-json] [--login-path <path>] [--username <user>] [--password <pass>] [--auth-path <path>]	Read-only or credentialed HTTP smoke test for the real Sealos App entry URL
sealos-log-scan.mjs	node sealos-log-scan.mjs --namespace <ns> --app <app> [--since 10m] [--tail 300] [--baseline <report.json|json>] [--min-window-seconds 60]	Read-only JSON scan of Pod/init/main logs plus Warning Event convergence after readiness, login, and random 404 checks
sealos-auth.mjs	node sealos-auth.mjs check|login|list|switch	Sealos Cloud authentication & workspace switching

All scripts output JSON. Run via Bash and parse the result.

For public web applications, run sealos-launchpad-network.mjs before HTTP smoke. Acceptance requires ok: true, an open public network, the expected Service port, and an App URL host match. The script emits an allowlisted network summary and excludes raw Launchpad application data, environment variables, Secrets, and kubeconfig content.

Runtime Event acceptance uses two scans. Capture the first report after readiness with no baseline, wait at least 60 seconds, then pass that report through --baseline for the final scan. Extend --min-window-seconds to cover one full known reconciliation, probe, or scheduled-work period. An initial Warning Event is an observation; a Warning that advances after the baseline, an unresolved referenced Secret, a Ready transition, a Pod replacement, or a restart delta is an active failure.

For intentional fault injection, retain a pre-injection report as evidence. After recovery reaches Ready, capture a fresh recovery baseline and compare the final scan against that recovery baseline after the full stability window.

Phase Overview

Phase	Action	Skip When
0 — Preflight	Capability scan, path-specific warnings, Sealos auth	Initial blockers resolved
0.5 — Template Fast Path	Match GitHub repo to a configured Sealos template	No match, or match cannot materialize template YAML
1 — Assess	Clone repo (or use current project), analyze deployability	Score too low → stop
2 — Detect	Find existing image (Docker Hub / GHCR / README)	Found → jump to Phase 5
3 — Dockerfile	Generate Dockerfile if missing	Already has one → skip
4 — Build & Push	docker buildx → GHCR (auto via gh CLI) or Docker Hub (fallback)	—
5 — Template	Generate Sealos application template	—
5.5 — Configure	Guide user through app env vars and inputs	No inputs needed
6 — Deploy	Deploy template to Sealos Cloud	—
6.5 — Runtime Truth Pass	Verify Launchpad public networking, the actual Sealos runtime, logs, Event convergence, App URL, login path, object-storage flow, and resource footprint	User explicitly requests deploy-only output

Execution rule: Phase 1 must never start while Phase 0 still has unresolved entry blockers. Docker, gh, builder, and registry failures must be reported early, but only become hard blockers if the run later requires local build/push.
