name: sealos-deploy description: Deploy any GitHub project to Sealos Cloud in one command. Assesses readiness, generates Dockerfile, builds image, creates Sealos template, and deploys — fully automated. Use when user says "deploy to sealos", "deploy this project", "deploy to cloud", "deploy this repo", mentions Sealos deployment, wants to deploy a GitHub URL or local project to a cloud platform, or asks about one-click deployment. Also triggers on "/sealos-deploy". metadata: author: labring 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.

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:

modules/preflight.md — Environment checks & Sealos auth
modules/pipeline.md — Full deployment pipeline (Phase 1–6)

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 >>:

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 the actual Sealos runtime, logs, App URL, login path, 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.
