kubernetes 用dockerfile 创建jenkins容器

dockerfile 创建jenkins

下载链接 ：Docker Hub

##这里用的是jenkinsforCentos版本

[root@hy-202 ~]# docker pull jenkins/jenkins:2.316-centos7
​

##push 到本地仓库

[root@hy-202 ~]# docker tag 55b7502f8749 harbor.hy.com/infra/jenkins:2.316-centos7
[root@hy-202 ~]# docker push harbor.hy.com/infra/jenkins:2.316-centos7

##push 到本地仓库
[root@hy-202 ~]# docker tag 55b7502f8749 harbor.hy.com/infra/jenkins:2.316-centos7
[root@hy-202 ~]# docker push harbor.hy.com/infra/jenkins:2.316-centos7

##创建目录

/data/k8s_data/dockerfile/jenkins

##下载get-docker.sh

[root@hy-205 jenkins]# curl -fsSL get.docker.com -o get-docker.sh
[root@hy-205 jenkins]# chmod a+x get-docker.sh

##dockerfile 文件如下

[root@hy-205 jenkins]# cat Dockerfile 
FROM harbor.hy.com/infra/jenkins:2.316-centos7
USER root
RUN /bin/cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && 
    echo 'Asia/Shanghai' >/etc/timezone
ADD id_rsa /root/.ssh/id_rsa
ADD config.json /root/.docker/config.json
ADD get-docker.sh /get-docker.sh
RUN echo "    StrictHostKeyChecking no" >> /etc/ssh/ssh_config &&
    /get-docker.sh

##执行dockerfile

[root@hy-205 jenkins]# docker build . -t harbor.hy.com/infra/jenkins:2.316-centos7-latest

##执行dockerfile
​

[root@hy-205 jenkins]# docker build . -t harbor.hy.com/infra/jenkins:2.316-centos7-latest

​
##执行成功

##测试是否可以链接git@gitee.com 

[root@hy-205 jenkins]# docker run --rm harbor.hy.com/infra/jenkins:2.316-centos7-latest ssh -T git@gitee.com
Warning: Permanently added 'gitee.com,180.97.125.228' (ECDSA) to the list of known hosts.
Hi 左丿仔! You've successfully authenticated, but GITEE.COM does not provide shell access.

[root@hy-205 jenkins]# docker push harbor.hy.com/infra/jenkins:2.316-centos7-latest
