为什么国内做持续集成各人都选择 Jenkins ,用 travis-ci 的人那么少呢？

在之后的该文中如是说了Gitlab天然情况的修建和CI与Gitlab的资本整合，所以那时次要就如是说Docker中修建CI的天然情况，Docker问世于云计算的黄金时代，它次要是如前所述Go词汇与此同时实现的开放源码罐子工程项目，现阶段有关Docker罐子的生态系早已很健全，所以数十家非支流的功课系统子公司都全力撑持Docker。那时次要就如是说在Docker中修建Jenkins的天然情况，有关Docker天然情况的修建在中后期的该文中逐步的如是说。CI就不必要负担的如是说了, 它是智能化试验中要要掌控的两个专业技能寡所周知，与此同时也是与此同时实现CICD资本整合的核心理念辅助东西寡所周知。

加拆好Docker的天然情况之后，继续施行docker run hello-world，就会表白如下表所示的重要信息：

在docker中加拆Jenkins，详细来说必要找出Jenkins的快照，与此同时提议加拆新一代版的Jenkins，假设加拆的是旧版的，可能将引致的情形是那类应用法式难以加拆，或是是加拆之后不相容等情形。继续施行如下表所示指示以获取Jenkins的快照：

docker pull jenkins/jenkins:lts 见莱盖后的截屏重要信息：

接纳docker images查阅快照，见莱盖后输入的重要信息：

留下来莱盖docker inspect f32b4bb22e4d查阅快照的重要信息，见莱盖后输入的重要信息：

在如上的重要信息中，就可以看到Jenkins的版为：JENKINS_VERSION=2.176.3。

留下来必要设置装备摆设Jenkins的目次，详细如下表所示如下表所示：

mkdir jenkins_home chown -R 1000 /root/jenkins_home/

最初是在罐子中启动Docker了，启动的指示如下表所示：

docker run --name ci -p 8080:8080 -p 5000:5000 -v /r

oot/jenkins_home/:/var/jenkins_home jenkins/jenkins:lts

#那里对参数做一点解释，次要就为 --name:对快照自定义的名称， -p:映射罐子端口和办事器端口,8080端口是jenkins的端口，5000端口用于毗连Agent，-v:参数把jenins的home目次挂载到当地，继续施行如上的指示后，输入的log为：

表白出如上的重要信息后，申明启动Jenkins已胜利，必要在阿里云的办事器开放8080的端口。接纳docker ps -a 能够查阅所有的罐子，见如下表所示截屏重要信息：

继续施行docker port ci查阅罐子的占用端口，见如下表所示的输入成果重要信息：

[root@wuya ~]# docker port ci 8080/tcp -> 0.0.0.0:8080 5000/tcp -> 0.0.0.0:5000 [root@wuya ~]#

能够看到罐子占用的端口情形，当然也能够继续施行如下表所示的指示查阅端口的占用情形，详细为：

[root@wuya ~]# lsof -i:8080;lsof -i:5000 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME docker-pr 9811 root 4u IPv6 16411374 0t0 TCP *:webcache (LISTEN) COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME docker-pr 9828 root 4u IPv6 16411481 0t0 TCP *:commplex-main (LISTEN)

Jenkins在罐子里面启动胜利后，与此同时8080的端口开放后，在阅读器输入http://x.x.x.x:8080/jenkins就会表白Jenkins的启动界面，如下表所示图所示：

留下来输入密码，然后是加拆应用法式以及点击Finish完成。当然下次在罐子里面怎么启动Jenkins了，继续施行docker ps -a | grep ci ，以获取到它的CONTAINER ID后，间接就能够启动或是停行，见指示：

[root@wuya ~]# docker stop bdf19546027b bdf19546027b [root@wuya ~]# docker port ci [root@wuya ~]# docker start bdf19546027b bdf19546027b [root@wuya ~]# docker port ci 5000/tcp -> 0.0.0.0:5000 8080/tcp -> 0.0.0.0:8080

当然与此同时继续施行docker stats CONTAINER ID，就能够得到某两个罐子的资本接纳情形，如查阅Jenkins的，见如下表所示的输入重要信息：
