Jenkins-在Centos上配置自動化部署（Jenkins+Gitlab+Rancher）

Jenkins-在Centos上配置自動化部署（Jenkins+Gitlab+Rancher）

環境：centos7

首先在服務器上安裝好Jenkins和Gitlab和Rancher

Gitlab安裝：http://www.javashuo.com/article/p-bdwquasu-hb.html

Jenkins安裝：http://www.javashuo.com/article/p-uizxhgev-gt.html

 Rancher安裝：http://www.javashuo.com/article/p-bbdatcwt-m.html

 

打開Jenkins，地址：http://192.168.122.199:8078/

 

 

 

 

添加憑據 

 

 

 增長全局憑據

類型：SSH類型

username:自定義

Key:C:\Users\lihongyuan\.ssh\id_rsa（如何生成 SSH 密鑰可在網上查到）

 

 

  肯定後，添加成功

 

 

 

  

建立一個新任務

 

 

 

項目配置General

 

 

 

配置源碼管理

注意提早安裝GitLab 插件。 

Repository URL:GitLab中的項目地址

credentials:憑據

獲取代碼的分支 此處以 master 爲例

 

 

 

構建觸發器

記下 這個地址，配置到 GitLab中 （當有分支有提交時，自動推送代碼過來，自動構建） 

GitLab 中的配置方式：http://www.javashuo.com/article/p-bdwquasu-hb.html

 

 

  

點擊高級，生成密鑰，密鑰配置到 GitLab中 （當有分支有提交時，自動推送代碼過來，自動構建） 

 

構建 執行shell腳本。

需安裝dotnet core 環境：http://www.javashuo.com/article/p-skantnaw-gp.html

也可在服務器上 /var/lib/jenkins/workspace 目錄下 運行下面的語句。

 

 

 

 

 

 

 

Jenkins在shell腳本運行docker權限報錯解決，參考：http://www.javashuo.com/article/p-dwmhopex-gk.html

Jenkins在執行shell腳本時可能會報相似以下的錯誤，是因爲Jenkins沒有docker權限

Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post http://%2Fvar%2Frun%2Fdocker.sock/v1.38/containers/create?name=my-node-8: dial unix /var/run/docker.sock: connect: permission denied.

解決方法

將jenkins用戶加入docker組
重啓Jenkins服務 

sudo gpasswd -a jenkins docker
systemctl restart jenkins

 

 

查看權限組

cat /etc/group

 

 

 

OK 配置完成，可從新構建測試。

 

 

Jenkins自動部署Rancher:

獲取Rancher API調用的語句，填寫在Execute Shell 中。以下：

Rancher API調用的語句，請查詢：http://www.javashuo.com/article/p-bbdatcwt-m.html

 

具體以下命令以下：

 

#!/bin/bash

var=`date +%Y%m%d%H%M%S`


#發佈
dotnet publish ProjNetCore2/ProjNetCore2.csproj -c Release -o ../publish/
#打鏡像

保存。

當Jenkins從新構建時，會自動調用Rancher的API，使Rancher項目從新部署。
