# 与 bootstrap.sh 配套. bootstrap 在每次 update 之前会把当前
|
|
# compose / .env / app.ini / nginx.conf 打包成一个快照存进
|
|
# $DATA_ROOT/lighthouse/snapshots/<TS>/. 这里负责把它恢复回去.
|
|
#
|
|
# 用法:
|
|
# bash rollback.sh # 回滚到上一个快照 (默认)
|
|
# bash rollback.sh --list # 列出所有可用快照
|
|
# bash rollback.sh --to <TS> # 回滚到指定快照
|
|
#
|
|
# 设计理念:
|
|
# - 数据盘 (Gitea repo / Postgres / Redis) **不动**, 只回滚配置
|
|
# 和 compose 编排; 这样数据安全, 行为可逆
|
|
# - 自动停 compose → 还原配置 → docker compose up -d → 健康检查
|
|
# - 写出回执到 _logs/rollback-*.json
