官方介紹

目前微服務盛行環境下，服務部署優先考慮Docker方式，便於遷移和彈性伸縮

官方映象介紹 GitLab Docker images

GitLab Docker images

Both GitLab CE and EE are in Docker Hub:

• GitLab CE Docker image
• GitLab EE Docker image

The GitLab Docker images are monolithic images of GitLab running all the necessary services on a single container.

In the following examples we are using the image of GitLab CE. To use GitLab EE instead of GitLab CE, replace the image name to gitlab/gitlab-ee:latest.

If you want to use the latest RC image, use gitlab/gitlab-ce:rc or gitlab/gitlab-ee:rc for GitLab CE and GitLab EE respectively.

The GitLab Docker images can be run in multiple ways:

• Run the image in Docker Engine
• Install GitLab into a cluster
• Install GitLab using docker-compose

docker-compose 指令碼

此處選擇社群版(CE)安裝，同時為了便於引數配置，使用docker-compose方式編寫指令碼檔案

Install GitLab using docker-compose

With Docker compose you can easily configure, install, and upgrade your Docker-based GitLab installation.

1. Install Docker Compose

2. Create a docker-compose.yml file (or download an example):

    web:
      image: 'gitlab/gitlab-ce:latest'
      restart: always
      hostname: 'gitlab.example.com'
      environment:
        GITLAB_OMNIBUS_CONFIG: |
          external_url 'https://gitlab.example.com'
          # Add any other gitlab.rb configuration here, each on its own line
      ports:
        - '80:80'
        - '443:443'
        - '22:22'
      volumes:
        - '/srv/gitlab/config:/etc/gitlab'
        - '/srv/gitlab/logs:/var/log/gitlab'
        - '/srv/gitlab/data:/var/opt/gitlab'

3. Make sure you are in the same directory as docker-compose.yml and run docker-compose up -d to start GitLab

Read “Pre-configure Docker container” to see how the GITLAB_OMNIBUS_CONFIG variable works.

Below is another docker-compose.yml example with GitLab running on a custom HTTP and SSH port. Notice how the GITLAB_OMNIBUS_CONFIG variables match the ports section:

web:
  image: 'gitlab/gitlab-ce:latest'
  restart: always
  hostname: 'gitlab.example.com'
  environment:
    GITLAB_OMNIBUS_CONFIG: |
      external_url 'http://gitlab.example.com:9090'
      gitlab_rails['gitlab_shell_ssh_port'] = 2224
  ports:
    - '9090:9090'
    - '2224:22'
  volumes:
    - '/srv/gitlab/config:/etc/gitlab'
    - '/srv/gitlab/logs:/var/log/gitlab'
    - '/srv/gitlab/data:/var/opt/gitlab'
複製程式碼

This is the same as using --publish 9090:9090 --publish 2224:22.

官方提示說明Docker CE版基於Omnibus版本，故環境配置也可參考相關文件

Omnibus文件目錄

Installation and Configuration using omnibus package

Note: This section describes the commonly used configuration settings. Check configuration section of the documentation for complete configuration settings.

• Installing GitLab
  • Manually downloading and installing a GitLab package
• Setting up a domain name/URL for the GitLab Instance so that it can be accessed easily
• Enabling HTTPS
• Enabling notification EMails
• Enabling replying via email
  • Installing and configuring postfix
• Enabling container registry on GitLab
  • You will require SSL certificates for the domain used for container registry
• Enabling GitLab Pages
  • If you want HTTPS enabled, you will have to get wildcard certificates
• Enabling Elasticsearch
• GitLab Mattermost Set up the Mattermost messaging app that ships with Omnibus GitLab package.
• GitLab Prometheus Set up the Prometheus monitoring included in the Omnibus GitLab package.
• GitLab High Availability Roles

結合配置目標編寫yaml檔案

注意：

• 此處郵件使用163郵箱（官方沒有提供163郵箱支援案例）
• Docker私服公鑰執行從私服上獲取
• 由於特殊原因，目標配置未啟動SSL安全連線，但GitLab可以通過簡單配置支援SSL並自動更新證書

配置文件

Let’s Encrypt Integration

Primary GitLab Instance

Note: Introduced in GitLab version 10.5 and disabled by default. Enabled by default in GitLab version 10.7 and later if external_url is set with the httpsprotocol and no certificates are configured.

Note: In order for Let’s Encrypt verification to work correctly, ports 80 and 443 will need to be accessible to the Let’s Encrypt servers that run the validation. Also note that the validation currently does not work with non-standard ports.

Caution Administrators installing or upgrading to GitLab version 10.7 or later and do not plan on using Let’s Encrypt should set the following in /etc/gitlab/gitlab.rb to disable:

letsencrypt['enable'] = false
複製程式碼

Add the following entries to /etc/gitlab/gitlab.rb to enable Let’s Encrypt support for the primary domain:

letsencrypt['enable'] = true                      # GitLab 10.5 and 10.6 require this option
external_url "https://gitlab.example.com"	  # Must use https protocol
letsencrypt['contact_emails'] = ['foo@email.com'] # Optional
