 - 节点容器 fallback 到 FTP：通常为 bundle 结构异常或健康检查失败（早期脚本在 `sh` 下执行）。当前 `node-bootstrap.sh` 已使用 `bash` 执行健康检查，并在本地安装成功后跳过 FTP。
 - 代理 502：查看容器 `argus-web-proxy` 的 `/var/log/nginx/error.log` 与启动日志中 `upstream check` 行；若后端未就绪（尤其 Kibana），等待 `02_wait_ready.sh` 通过后再访问。
+
+### 在 worker 上用 compose 起 GPU 节点的网络预热（overlay not found）
+在多机 Swarm 场景，如果在 worker（如 `lm1`）上直接运行 `05_gpu_node_up.sh`，`docker compose` 对 external overlay `argus-sys-net` 的本地预检查可能报错 `network ... not found`。这是因为 worker 尚未在本地“加入”该 overlay。
+
+Workaround：先在 worker 启一个临时容器加入 overlay 进行“网络预热”，随后再运行 GPU compose。
+
+```
+# 在 worker 节点（lm1）
+cd src/sys/swarm_tests
+set -a; source .env; source .env.nodes; set +a
+
+# 预热 overlay（默认 600s 超时自动退出，可重复执行）
+bash scripts/05a_net_warmup.sh
+
+# 然后再启动 GPU 节点
+bash scripts/05_gpu_node_up.sh
+```
+
+清理时 `scripts/99_down.sh` 会顺带移除预热容器 `argus-net-warmup`。
+
+更推荐的做法是改用 `docker stack deploy` 由 manager 调度 GPU 节点（支持渐进式扩容与节点约束），详见 `specs/issues/2025-11-07-swarm-compose-worker-overlay-network-not-found-lm1.md`。
+
+### （可选）Stack 部署 GPU 节点（manager 上执行）
+前置：已在 manager（lm2）完成 `00_bootstrap.sh` 与 `01_server_up.sh`，并通过 `02_wait_ready.sh` 生成 `.env.nodes`；给目标 GPU 节点打标签 `argus.gpu=true`。
+
+```
+cd src/sys/swarm_tests
+# 给 GPU 节点打标签（示例）
+docker node update --label-add argus.gpu=true lm1
+
+# 可按需覆盖挂载路径（每个 GPU 节点都需存在同一路径）
+export AGENT_VOLUME_PATH=/data1/yuyr/dev/argus/src/sys/swarm_tests/private-gpu-nodes/argus/agent
+
+# 在 manager 上部署（global 模式，自动在打标节点各拉起 1 副本）
+bash scripts/05b_gpu_stack_deploy.sh
+
+# 查看
+docker stack services argus-swarm-gpu
+docker stack ps argus-swarm-gpu
+```
+
+移除 stack：`docker stack rm argus-swarm-gpu`（不会删除 overlay 网络与数据目录）。
