自定义Dockerfile

在运维主机HDSS7-200.host.com上编辑自定义dockerfile

复制/data/dockerfile/jenkins/Dockerfile

FROM harbor.od.com/public/jenkins:v2.164.1 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/sshd_config &&\ /get-docker.sh

 

这个Dockerfile里我们主要做了以下几件事

• 设置容器用户为root
• 设置容器内的时区
• 将ssh私钥加入（使用git拉代码时要用到，配对的公钥应配置在gitlab中）
• 加入了登录自建harbor仓库的config文件
• 修改了ssh客户端的
• 安装一个docker的客户端

生成ssh密钥对：

复制
