之前使用 docker-compose 来架设 GitLab：【浅谈 Docker 基础】GitLab 篇：简易架设
今天则要来简单记录一下，如何在 GitLab 设定 Gmail 邮件伺服器

设定 Gmail

environment:  GITLAB_OMNIBUS_CONFIG: |    gitlab_rails['smtp_enable'] = true    gitlab_rails['smtp_address'] = "smtp.gmail.com"    gitlab_rails['smtp_port'] = 587    gitlab_rails['smtp_user_name'] = "{your_account}@gmail.com"    gitlab_rails['smtp_password'] = "{your_password}"    gitlab_rails['smtp_domain'] = "smtp.gmail.com"    gitlab_rails['smtp_authentication'] = "login"    gitlab_rails['smtp_enable_starttls_auto'] = true    gitlab_rails['smtp_tls'] = false    gitlab_rails['smtp_openssl_verify_mode'] = 'peer'

version: "3.6"services:  gitlab:    image: gitlab/gitlab-ce:latest    restart: always    privileged: true    ports:      - '80:80'      - '443:443'      - '22:22'    volumes:      - '~/gitlab/data:/var/opt/gitlab'      - '~/gitlab/logs:/var/log/gitlab'      - '~/gitlab/config:/etc/gitlab'    environment:      GITLAB_OMNIBUS_CONFIG: |        gitlab_rails['smtp_enable'] = true        gitlab_rails['smtp_address'] = "smtp.gmail.com"        gitlab_rails['smtp_port'] = 587        gitlab_rails['smtp_user_name'] = "{your_account}@gmail.com"        gitlab_rails['smtp_password'] = "{your_password}"        gitlab_rails['smtp_domain'] = "smtp.gmail.com"        gitlab_rails['smtp_authentication'] = "login"        gitlab_rails['smtp_enable_starttls_auto'] = true        gitlab_rails['smtp_tls'] = false        gitlab_rails['smtp_openssl_verify_mode'] = 'peer'

docker-compose up -d

若设定没有问题，之后系统就能正常的发送相关的邮件了
