chatwork/postfix本镜像是基于Postfix邮件服务器的Docker镜像,旨在提供轻量级、易于部署的邮件服务。由于Postfix依赖syslog守护进程进行日志输出,镜像集成了Supervisord进程管理工具,用于协同管理Postfix主进程与rsyslog日志服务,确保服务稳定运行及日志正常记录。主要用途为快速部署SMTP服务,适用于需要简易邮件发送能力的场景。
通过以下命令启动Postfix容器,将主机的***端口映射到容器的25端口(SMTP端口):
bashdocker run --rm --name postfix -p ***:25 chatwork/postfix
参数说明:
--rm:容器退出后自动删除,避免残留容器文件。--name postfix:指定容器名称为postfix,便于管理。-p ***:25:将主机的***端口映射到容器内的25端口(Postfix默认SMTP端口)。chatwork/postfix:镜像名称。容器启动后,将输出类似以下日志,表明Postfix和rsyslog进程正常运行:
2018-11-07 09:21:36,518 INFO Set uid to user 0 succeeded 2018-11-07 09:21:36,520 INFO supervisord started with pid 13 2018-11-07 09:21:37,522 INFO spawned: 'rsyslog' with pid 15 2018-11-07 09:21:37,524 INFO spawned: 'master' with pid 16 2018-11-07T09:21:37.660367+00:00 1a6c8af85c6f postfix/postfix-script[81]: starting the Postfix mail system 2018-11-07T09:21:37.663653+00:00 1a6c8af85c6f postfix/master[82]: daemon started -- version 3.3.0, configuration /etc/postfix 2018-11-07 09:21:38,665 INFO success: rsyslog entered RUNNING state, process has stayed up for > than 1 seconds (startsecs) 2018-11-07 09:21:38,665 INFO success: master entered RUNNING state, process has stayed up for > than 1 seconds (startsecs)
通过curl或telnet工具测试Postfix服务是否正常监听端口:
bashcurl telnet://localhost:***
若服务正常,将返回Postfix的SMTP欢迎信息:
220 fdb0484594ab.localdomain ESMTP Postfix
/etc/postfix),无需额外设置即可运行基础SMTP服务。/etc/postfix目录,例如:
bashdocker run --rm --name postfix -p ***:25 -v /host/postfix/config:/etc/postfix chatwork/postfix
