Jenkins+Gitlab+Ansible自動化部署(五)

Freestyle Job實現靜態網站部署交付（接Jenkins+Gitlab+Ansible自動化部署（四）http://www.javashuo.com/article/p-suybpulk-g.html）

• 環境構建
• 編寫ansible playbook腳本實現靜態網頁遠程部署
• 將playbook部署腳本提交到GitLab倉庫
• 構建Freestyle Job任務框架
• Jenkins集成Ansible與Gitlab實現靜態網頁的自動化部署

首先肯定本身的環境已經準備完畢。

添加描述

添加Git倉庫（該倉庫地址即爲上述配置的ansible-playbook-repo的倉庫地址）

參數化構建過程

添加構建步驟

在執行shell彈出的輸入框內輸入如下內容

#/bin/sh

set +x
source /home/deploy/.py3-a2.5-env/bin/activate
source /home/deploy/.py3-a2.5-env/ansible/hacking/env-setup -q

cd $WORKSPACE/nginx_playbooks
ansible --version
ansible-playbook --version

ansible-playbook -i inventory/$deploy_env ./deploy.yml -e project=nginx -e branch=$branch -e env=$deploy_env

點擊「Save」，而後點擊「Build with Parameters」，在右側下拉列表中選擇dev，點擊「Build」

查看輸出信息

驗證目標主機是否部署成功，在瀏覽器輸入test.exmaple.com查看

前提是保證本地windows主機下的C:\Windows\System32\drivers\etc\hosts文件中末尾有以下對應關係

192.168.244.130 gitlab.example.com
192.168.244.131 jenkins.example.com
192.168.244.132 ansible.example.com
192.168.244.133 test.example.com
