前言
jenkins是常用的开源持续继承工具，现在所在的工作场景，也是使用jenkins进行基于github代码的拉取、打包、构建、部署的一系列流程，并结合了容器和函数计算实现金丝雀部署。本文先从基础的jenkins环境搭建开始。
一 jenkins本地安装部署
jenkins官网的下载速度太慢，可使用下面镜像：
官网文档，jenkins入门，下载jenkins.war之后，使用下面命令启动和访问：
1.下载 Jenkins.
- 2.打开终端进入到下载目录.
- 3.运行命令
java -jar jenkins.war --httpPort=8080. - 4.打开浏览器进入链接
http://localhost:8080. - 5.按照说明完成安装.
按照说明，java -jar jenkins.war --httpPort=8080 后控制台输出如下：

浏览器访问，注意，页面会提示等待初始化，结束后会自动跳转到首页，这个过程会花1-2分钟时间，并非出错。
待弹出上面这个输入秘钥页面时，输入上面的1072ca47a779473dbad450aee6d6946e 完成安装，进入后续操作即可。
完成后，进入熟悉的页面：
二 docker下的安装部署
注，这里不再介绍docker的安装方式，默认已完成本地的docker部署。
笔者使用的docker版本如下：
flamingskys:logs $ docker --version Docker version 19.03.5, build 633a0ea
在docker中下载并安装jenkins，可参照说明: docker中安装jenkins，使用镜像： jenkinsci/blueocean，这是来自 Docker Hub repository 的jenkins Docker镜像。
安装步骤：
1、使用下面命令直接运行：
docker run -p 8080:8080 jenkinsci/blueocean
2、run成功后，当看到下面输出时，代表已经启动完成。浏览器中通过http://localhost:8080端口访问，与本地部署相同：密码： d71cb009aa2e4343896110ccbc86778d
