2.jenkins環(huán)境搭建與啟動(dòng)

jenkins的環(huán)境搭建步驟:
1.搜索jenkins：docker search jenkins
2.拉取jenkins鏡像：docker pull jenkins/jenkins:lts
3.查看jenkins鏡像：docker images
4.創(chuàng)建本地?cái)?shù)據(jù)卷:
mkdir -p /var/jenkins_home/ #創(chuàng)建目錄
chmod 777 /var/jenkins_home/ #修改權(quán)限目錄
5.創(chuàng)建容器:docker run -id --name=jenkins -p 7070:8080 -v /var/jenkins_home/:/var/jenkins_home jenkins/jenkins:lts
其中命令詳解：注意冒號(hào)后面的全部是固定值，不能改變，前面可以變更。
-d:容器后臺(tái)運(yùn)行
-p:端口映射
-v:數(shù)據(jù)卷掛載，綁定數(shù)據(jù)庫(kù)
6.配置jenkins，訪問(wèn)網(wǎng)址：http://宿主機(jī)ip:7070/
7.界面進(jìn)入jenkins,輸入管理員密碼：cat /var/jenkins_home/secrets/initialAdminPassword #獲取管理員密碼

提升技巧
1.容器的配置文件修改對(duì)應(yīng)的端口號(hào)---修改完請(qǐng)重啟容器
/var/lib/docker/containers/容器的id/hostconfig.json
docker start 容器id
2.docker logs 容器id #指令獲取jenkins密碼
jenkins密碼獲取執(zhí)行命令-方式一：
docker logs 132e5cf78f6a
或者
2.cat /var/jenkins_node/secrets/initialAdminPassword#該指令也可以獲取jenkins密碼
jenkins密碼獲取執(zhí)行命令-方式二：
[root@ecs-429b ~]$>cat /var/jenkins_home/secrets/initialAdminPassword

3.jenkins下安裝python相關(guān)資源

4.jenkins相關(guān)資源文檔
