# 集群一次性准备（在 42 上）:

#
# GitHub Secrets（本仓 Settings → Secrets）:
#   SSH_K3S_HOST      — 42 公网 IP
#   SSH_K3S_USERNAME  — 一般 root
#   SSH_K3S_PASSWORD  — SSH 密码
#
# 排障：看哪个 step 红了
#   1 print-info     — 仅输出变量，几乎不会挂
#   2 check-cluster  — SSH / kubeconfig / 节点不通
#   3 check-secrets  — 未跑 16-setup-kaniko，或 Secret 名不对
#   4 kaniko-build   — 拉代码 / Dockerfile / 推 TCR（看 Job 日志）
#   5 set-image      — Deployment 名或容器名不对
#   6 rollout        — 镜像拉不下来 / 探针失败 / 资源不够
