背景介绍

作为一个老派程序员，偶尔能接到一些私单，不少私单涉及到代码安全问题，就不是很适合用Gitlab、Gitee 等在线代码托管服务了，于是在我的开发服务器上自己搭建了一个 git 服务，可选的git 服务有很多，如：：Gitea、Gogs、Gitlab 等，由于公司环境基本上用 Gitlab，且Gitlab 功能足够强大，所以便选择了 Gitlab 作为服务端，Gitlab 在国内成立了极狐公司（https://gitlab.cn/）专门运营国内的 Gitlab，在部署的时候也就选择了 Gitlab 的极狐版本，部署的完整 docker-compose.yml 如下：

services:
  gitlab:
    image: 'registry.gitlab.cn/omnibus/gitlab-jh:latest'
    # image: 'registry.gitlab.cn/omnibus/gitlab-jh:16.11.3'
    #image: 'registry.gitlab.cn/omnibus/gitlab-jh:16.7.7'
    restart: always
    container_name: gitlab
    hostname: 'git.work.zhuzhilong.com'
    environment:
      GITLAB_OMNIBUS_CONFIG: |
        external_url 'http://git.work.zhuzhilong.com'
        # Add any other gitlab.rb configuration here, each on its own line
        alertmanager['enable']=false
    networks:
      - net-zzl
    ports:
      - '8007:80'
      - '2223:22'
    volumes:
      - './config:/etc/gitlab'
      - './logs:/var/log/gitlab'
      - './data:/var/opt/gitlab'
      - ../hosts:/etc/hosts
      - /etc/timezone:/etc/timezone:ro
      - /etc/localtime:/etc/localtime:ro
    shm_size: '256m'
networks:
  net-zzl:
    name: bridge_zzl
    external: true

在开发过程中，涉及多成员协作，而 Gitlab 自带的邮件服务还是很有必要的，所以本次我们就将我们的 gitlab 服务搭上邮件的快车。

配置过程如下：

1、进入 docker 容器

docker exec -it gitlab /bin/bash

2、编辑 /etc/gitlab/gitlab.rb 文件

### GitLab email server settings
###! Docs: https://docs.gitlab.com/omnibus/settings/smtp.html
###! **Use smtp instead of sendmail/postfix.**

gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "smtp.feishu.cn"
gitlab_rails['smtp_port'] = 465
gitlab_rails['smtp_user_name'] = "sender@zhuzhilong.com"
gitlab_rails['smtp_password'] = "xxxxxxxx"
gitlab_rails['smtp_domain'] = "mail.feishu.cn"
gitlab_rails['smtp_authentication'] = "login"
# gitlab_rails['smtp_enable_starttls_auto'] = true
gitlab_rails['smtp_tls'] = true
gitlab_rails['smtp_pool'] = false

###! **Can be: 'none', 'peer', 'client_once', 'fail_if_no_peer_cert'**
###! Docs: http://api.rubyonrails.org/classes/ActionMailer/Base.html
# gitlab_rails['smtp_openssl_verify_mode'] = 'none'

# gitlab_rails['smtp_ca_path'] = "/etc/ssl/certs"
# gitlab_rails['smtp_ca_file'] = "/etc/ssl/certs/ca-certificates.crt"

### Email Settings

gitlab_rails['gitlab_email_enabled'] = true

##! If your SMTP server does not like the default 'From: gitlab@gitlab.example.com'
##! can change the 'From' with this setting.
gitlab_rails['gitlab_email_from'] = 'xxxx@zhuzhilong.com'
gitlab_rails['gitlab_email_display_name'] = '朱治龙git'
gitlab_rails['gitlab_email_reply_to'] = 'reply@zhuzhilong.com'
# gitlab_rails['gitlab_email_subject_suffix'] = ''
# gitlab_rails['gitlab_email_smime_enabled'] = false
# gitlab_rails['gitlab_email_smime_key_file'] = '/etc/gitlab/ssl/gitlab_smime.key'
# gitlab_rails['gitlab_email_smime_cert_file'] = '/etc/gitlab/ssl/gitlab_smime.crt'
# gitlab_rails['gitlab_email_smime_ca_certs_file'] = '/etc/gitlab/ssl/gitlab_smime_cas.crt'

3、使配置生效并重启服务

gitlab-ctl reconfigure && gitlab-ctl restart

4、验证邮件发送服务

可在个人资料 -> 电子邮件 中添加新的邮件地址：

添加后，对应的邮箱会收到如下验证邮件即表示配置成功了：
