# =============================================================================
# Octop 容器入口脚本
#
# 环境变量:
#   HOME                      — 必须为 /data，使 ~/.octop 映射到数据卷
#   OCTOP_DEFAULT_PASSWORD    — 首次管理员密码（须 ≥8 位且含字母和数字）。
#                               合格则 octop init 建账号；未设置或未通过
#                               策略则不建管理员，启动后走 Web 设置向导。
#   OCTOP_ADMIN_USERNAME      — 首次管理员用户名（默认: admin）
#   OCTOP_ADMIN_DISPLAY_NAME  — 可选显示名
#   OCTOP_PORT                — 服务端口（默认: 8088）
#
# 首次引导（issue #502）：容器不得因弱默认密码重启循环。未设置或不合格
# 的 OCTOP_DEFAULT_PASSWORD 不再静默换成随机管理员密码，而是把向导口令
# 写到数据卷（/data/.octop/octop-login.txt），打开页面走设置向导。

Octop Setup Required
====================
URL:      http://<host>:${PORT}

No admin account has been created yet.
Open the dashboard and complete the setup wizard.

Wizard password: ${pw}

This password only unlocks the wizard (same value as octop-login.txt).
Choose the admin username and password in the browser.

Octop Login Credential
======================
URL:      http://<host>:${PORT}
Username: ${ADMIN_USERNAME}
Password: ${password}

Please change this password after first login!
  - Via Web: avatar menu → Change password
  - Via CLI: docker exec -it <container> octop user passwd --username $ADMIN_USERNAME

This file is rewritten whenever the initial password is (re)generated here.
If you changed the password inside the Web console, that password wins.
