準備工做

下載安裝包

# Linux x86-64
sudo wget -O /usr/local/bin/gitlab-runner https://gitlab-runner-downloads.s3.amazonaws.com/latest/binaries/gitlab-runner-linux-amd64

# Linux x86
sudo wget -O /usr/local/bin/gitlab-runner https://gitlab-runner-downloads.s3.amazonaws.com/latest/binaries/gitlab-runner-linux-386

# Linux arm
sudo wget -O /usr/local/bin/gitlab-runner https://gitlab-runner-downloads.s3.amazonaws.com/latest/binaries/gitlab-runner-linux-arm

若是是離線安裝的話，能夠手工聯網下載，而後放到內網中，放到/usr/local/bin目錄下，並命名爲gitlab-runner

# 賦予可執行權限
sudo chmod +x /usr/local/bin/gitlab-runner

# 建立 GitLab CI 用戶
sudo useradd --comment 'GitLab Runner' --create-home gitlab-runner --shell /bin/bash
 
# 安裝
sudo gitlab-runner install --user=gitlab-runner --working-directory=/home/gitlab-runner

# 運行
sudo gitlab-runner start

註冊 Runner

首先須要準備URL和Token，能夠在 GitLab 項目的 settings->CI/CD->Runners settings 中找到

# 註冊
sudo gitlab-runner register

# 輸入本地的 gitlab URL
Please enter the gitlab-ci coordinator URL (e.g. https://gitlab.com )
https://gitlab.com

# 輸入 Token
Please enter the gitlab-ci token for this runner
xxx

# 輸入 tag, 注意要跟 job 的 tag 一致，後續詳細說明
Please enter the gitlab-ci tags for this runner (comma separated):
my-tag,another-tag

# 選擇 executor, 
Please enter the executor: ssh, docker+machine, docker-ssh+machine, kubernetes, docker, parallels, virtualbox, docker-ssh, shell:
docker

使用 tags

Runner 默認只會在配置了和自身 tags 一致的項目上運行，是爲了防止 Runner 運行在大量項目上出現問題。

同時能夠在 Runner 中取消該設置，容許 Runner 運行在無 tags 的項目上，配置以下

1. Visit your project’s Settings ➔ CI/CD
2. Find the Runner you wish and make sure it’s enabled
3. Click the pencil button
4. Check the Run untagged jobs option
5. Click Save changes for the changes to take effect

Executor 比較

Executor	SSH	Shell	VirtualBox	Parallels	Docker	Kubernetes
Clean build environment for every build	✗	✗	✓	✓	✓	✓
Migrate runner machine	✗	✗	partial	partial	✓	✓
Zero-configuration support for concurrent builds	✗	✗ (1)	✓	✓	✓	✓
Complicated build environments	✗	✗ (2)	✓ (3)	✓ (3)	✓	✓
Debugging build problems	easy	easy	hard	hard	medium	medium

1. It’s possible, but in most cases it is problematic if the build uses services installed on the build machine
2. It requires to install all dependencies by hand
3. For example using Vagrant

GitLab 中配置 Runner

在 GitLab 項目中新增.gitlab-ci.yml ，能夠選擇預先設置好的模版。
