# 0524 平台：按现有约定替换/回滚单个（或多个）服务容器
|
|||
|
|
# 位置：服务器 /mnt/web/0524-replace.sh
|
|||
|
|
#
|
|||
|
|
# 用法：
|
|||
|
|
# bash 0524-replace.sh admin # 用 0524admin:latest 重建 admin
|
|||
|
|
# bash 0524-replace.sh fishgame admin # 一次替换多个
|
|||
|
|
# TAG=dual-20261008 bash 0524-replace.sh admin # 回滚 admin 到旧镜像
|
|||
|
|
#
|
|||
|
|
# 约定（与线上既有部署保持一致）：
|
|||
|
|
# - 网络 webapi_backend
|
|||
|
|
# - 端口只绑 127.0.0.1
|
|||
|
|
# - 配置挂载 /mnt/web/config -> /app/Config（全服务共用）
|
|||
|
|
# - 日志挂载 /mnt/web/logs -> /app/logs
|
|||
|
|
# - ASPNETCORE_URLS 按各服务内部端口
|
