[Gitlab] 使用Gitlab進行自動部署之配置自動部署腳本

 

一、環境說明

當前Gitlab Runner與需要進行自動部署服務的目標機器是同一臺機器，環境說明如下

Gitlab Runner宿主機、目標機器

• 系統：CentOS Linux release 7.4.1708 (Core)
• IP：172.50.13.11

Gitlab Runner 環境

• Docker環境
• Docker鏡像：gitlab/gitlab-runner:latest

二、配置ssh密鑰進行免登錄

進入Gitlab Runner容器內，使用gitlab-runner用戶生產公鑰，並將公鑰拷貝到目標機器上，配置到目標服務器的授權密鑰列表中，後續遠程操作時可以免輸入密碼。

查看當前Gitlab Runner容器

fac5a3deb2b7        gitlab/gitlab-runner:latest   "/usr/bin/dumb-init …"   16 hours ago        Up 16 hours                                             gitlab-runner

進入容器

docker exec -it fac5a3deb2b7 /bin/bash

查看確認當前用戶

cat /etc/passwd

確認有gitlab-runner，如下紅色部分

 

 

 切換到gitlab-runner用戶，生成密鑰

su gitlab-runner
ssh-keygen

直接回車，自動生成密鑰到/home/gitlab-runner/.ssh/id_rsa目錄下

 拷貝密鑰到目標機器

ssh-copy-id -i /home/gitlab-runner/.ssh/id_rsa.pub  -p22 [email protected]

測試面密鑰登錄

ssh [email protected]

 

 退出當前容器

exit

　　此時，gitlab-ruuner中的gitlab-runner用戶可以免登錄進行遠程操作目標機器

三、配置自動部署腳本

當前時後端服務項目，添加了mvn倉庫的緩存配置，加快打包速度
