Sealos Deploy

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:

⚠️ 即将删除 <resource kind>/<resource name>，数据不可恢复。确认？(y/n)

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

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)

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 >>:

[2026-03-05 14:30:38] Status: 201 — deployed successfully
[2026-03-05 14:30:38] === DONE ===

On error, log the error details before stopping:

[2026-03-05 14:30:10] === ERROR ===
[2026-03-05 14:30:10] Phase: 4 (Build & Push)
[2026-03-05 14:30:10] Error: docker buildx build failed — "npm ERR! Missing script: build"
[2026-03-05 14:30:10] Retry: 1/3

At the very end, tell the user where the log is:

Log saved to: ~/.sealos/logs/deploy-20260305-143001.log

Scripts

Script	Usage	Purpose
score-model.mjs	node score-model.mjs <repo-dir>	Deterministic readiness scoring (0-12)
validate-artifacts.mjs	node validate-artifacts.mjs --dir <work-dir>	Validate .sealos JSON artifacts against enforced schemas
detect-image.mjs	node detect-image.mjs <github-url> [work-dir] or node detect-image.mjs <work-dir>	Detect existing Docker/GHCR images
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)
ensure-image-pull-secret.mjs	node ensure-image-pull-secret.mjs <namespace> <secret-name> <image-ref> [deployment-name]	Create/update app-scoped GHCR pull Secret and optionally patch an existing Deployment to reference it
gh-refresh-scopes.mjs	node gh-refresh-scopes.mjs write:packages	Refresh GHCR package access in the current TTY; write:packages is sufficient for both push and private pull in this workflow
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-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.

Phase Overview

Phase	Action	Skip When
0 — Preflight	Capability scan, path-specific warnings, Sealos auth	Initial blockers resolved
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	—

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.
