minimum2scp/baseimage 镜像说明

镜像概述和主要用途

该镜像基于 minimum2scp/debian 构建，默认运行 /opt/init-wrapper/sbin/init 初始化脚本，集成sysvinit初始化系统及多个基础守护进程，适用于需要同时运行SSH服务、日志管理和定时任务的Docker环境，可作为基础镜像构建依赖这些服务的应用。

核心功能和特性

• 初始化流程：默认执行 /opt/init-wrapper/sbin/init，依次运行 /opt/init-wrapper/pre-init.d 目录下的脚本，替换 sysvinit-core 包提供的 /sbin/init，启动 sshd、rsyslogd、cron 守护进程，最后通过 /etc/rc.local 运行 /opt/init-wrapper/post-init.d 目录下的脚本。
• 本地化支持：支持 ja_JP.UTF-8 locale（默认locale为C）。
• 时区设置：默认时区为 Asia/Tokyo。
• 系统工具：预装 etckeeper，用于跟踪 /etc 目录的变更。

使用场景和适用范围

• 需要在Docker容器中运行SSH服务以进行远程管理的场景。
• 需同时运行日志收集（rsyslogd）和定时任务（cron）的应用环境。
• 作为基础镜像构建需要多后台服务支持的应用容器。

使用方法和配置说明

启动容器

使用以下命令启动容器，映射SSH端口（示例映射到主机2222端口）：

docker run -d -p 2222:22 minimum2scp/baseimage:latest

SSH登录容器

直接通过容器IP登录

ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no debian@<容器IP地址>

通过映射端口登录

ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -p 2222 debian@localhost

登录相关配置

• 可用用户：debian
• 默认密码：debian
  • 修改密码：设置环境变量 USER_PASSWORD（详见 /opt/init-wrapper/pre-init.d/04-chpass-and-sshkey）
  • 设置SSH公钥：设置环境变量 USER_SSH_KEY_URI，将公钥写入 ~/.ssh/authorized_keys（详见同上脚本）
• 用户权限：debian 可无密码使用 sudo 命令
• 用户ID信息：uid=2000(debian) gid=2000(debian) groups=2000(debian),4(adm),27(sudo)

进程列表

容器运行时的典型进程结构如下：

UID        PID  PPID  C STIME TTY      STAT   TIME CMD
