| 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". |
| 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
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.
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 authmodules/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 |
| 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 | — |

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.
