第二十七章 Centos7下Docker安装Jenkins

一、拉取Jenkins镜像文件

[root@ip-10-0-12-212 ~]# docker pull jenkins/jenkins

二、创建挂载目录并授权

[root@ip-10-0-12-212 ~]# mkdir -p /data/jenkins_mount
[root@ip-10-0-12-212 ~]# chmod  777 /data/jenkins_mount

三、创建并启动Jenkins容器

[root@ip-10-0-12-212 ~]# docker run \
-itd \
-p 10240:8080 \
-p 10241:50000 \
-v /data/jenkins_mount:/var/jenkins_home \
-v /etc/localtime:/etc/localtime \
--restart always \
--privileged=true \
--name Datalake_Jenkins \
jenkins/jenkins

四、查看jenkins是否启动成功

[root@ip-10-0-12-212 ~]# docker ps
CONTAINER ID   IMAGE             COMMAND                  CREATED          STATUS          PORTS                                                                                        NAMES
e0a9964d61fd   jenkins/jenkins   "/sbin/tini -- /usr/…"   13 seconds ago   Up 12 seconds   0.0.0.0:10240->8080/tcp, :::10240->8080/tcp, 0.0.0.0:10241->50000/tcp, :::10241->50000/tcp   Datalake_Jenkins

五、查看docker容器日志

[root@ip-10-0-12-212 ~]# docker logs Datalake_Jenkins

webroot: EnvVars.masterEnvVars.get("JENKINS_HOME")
