# MoShiro 节点一键安装（Agent 和 Probe 共用同一份）。面板在 /install?code=… 生成这份脚本，把下面四个值填好：
|
||
# curl -fsSL 'https://panel/install?code=jt_…' | bash （macOS 用 zsh）
|
||
# 做的事：用 Docker 或 Podman 起一个容器，身份和配置存在命名卷里（重启、换新镜像重建都不用再给参数），节点名字默认取主机名。
|
||
# 可选环境变量：MOSHIRO_NAME=节点名字（名字被占用时用）、MOSHIRO_ENGINE=docker|podman、MOSHIRO_DRY_RUN=1（只打印命令）、
|
||
# MOSHIRO_ALLOW_UNVERIFIED=1（面板还没有已签名的发布清单时，不验签、按标签安装；默认拒绝）。
|
||
# 镜像：向面板取 CI 签名的发布清单，用下面内置的发布公钥验签，再按清单里的 digest 拉取（镜像按内容寻址，换不了）。
