1.概述

  容器服务云上环境与弹内差别较大，很多弹内支持默认埋点的 agent 在云上没法使用，同时需要预先部署一些云上环境需要的 agent, 因而云上的基础镜像跟弹内差异较大，需要从centos基础镜像开始配置环境。
  容器镜像服务在云上，当云效部署时，需要从镜像服务拉取基础镜像建立镜像，因而需要将基础镜像 push 到镜像服务仓库中。
  为了方便镜像 push 到镜像仓库，因而采用一个跳板机制作镜像，并上传到镜像仓库的方式来加快镜像制作和上传。
最终执行环境：

• 本地办公电脑执行打包脚本命令；
• 跳板机打包镜像；
• 跳板机镜像上传到镜像仓库。

2. 镜像制作：

  主要步骤有：

1. 跳板机环境安装 Docker；
2. 上传镜像中需要的第三方包和基础软件安装包上传到跳板机，比如 jdk, agent等；
3. 编写本地执行脚本，执行镜像打包，并 push 镜像到仓库；

## 2.1 镜像打包跳板机环境配置：
  安装 docker:

1、检查内核版本，必须是3.10及以上     
uname -r   
注：如果版本低于3.10，使用 yum update 升级   
2、安装docker  
yum install docker
3、输入y确认安装
4、启动docker
[root@localhost ~]# systemctl start docker
[root@localhost ~]# docker -v
Docker version 1.12.6, build 3e8e77d/1.12.6
5、开机启动docker
[root@localhost ~]# systemctl enable docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.
6、停止docker
systemctl stop docker

2.2 上传安装依赖包：

上传 jdk, Agent 等应用依赖的第三方包：

#!/bin/bash
env=$1

if [ ! -n "${env}" ]; then
  echo "Usage: ./upload.sh env "
  echo "env is resource upload or erase enviroment name:daily or online"
  exit 1
fi
## 设置跳板机登录证书和账号等
if [ ${env} == "online" ]; then
    echo "upload wukong resource to online jump machine."
    source "../ssh-production.sh" 
else
    echo "upload wukong resource to daily jump machine."
    source "../ssh-testing.sh"
fi
## 删除原有资源目录
echo "remove file on jump machine ssh  -i ${JUMP_CERT} -t ${JUMP_USER}@${JUMP_MACHINE}  'rm -rf /home/admin/resources/; mkdir /home/admin/resources/;'"
## ssh  -i ${JUMP_CERT} -t ${JUMP_USER}@${JUMP_MACHINE}  "rm -rf /home/admin/resources; mkdir /home/admin/resources/;"
## 上传依赖软件
echo "scp packag/home/admin/resources/target to jump machine ${JUMP_MACHINE}"
scp -i ${JUMP_CERT} -r ./jdk/  ${JUMP_USER}@${JUMP_MACHINE}:/home/admin/resources
scp -i ${JUMP_CERT} -r ./sunfire/  ${JUMP_USER}@${JUMP_MACHINE}:/home/admin/resources
${JUMP_USER}@${JUMP_MACHINE}:/home/admin/resources
scp -i ${JUMP_CERT}  ./tengine-yun-1.0.2-1652752.el7u2.x86_64.rpm  ${JUMP_USER}@${JUMP_MACHINE}:/home/admin/resources
scp -i ${JUMP_CERT}  ./taobao-tomcat-7.0.59.3.tar.gz  ${JUMP_USER}@${JUMP_MACHINE}:/home/admin/resources
scp -i ${JUMP_CERT}  ./start.sh  ${JUMP_USER}@${JUMP_MACHINE}:/home/admin/resources
scp -i ${JUMP_CERT}  ./shutdown.sh  ${JUMP_USER}@${JUMP_MACHINE}:/home/admin/resources

echo "upload success."

2.3 编写执行脚本：

本地办公环境通过 ssh 执行打包命令：

#!/bin/bash
APP_NAME=my-pandora-boot-base
NAMESPACE=app-base
REPO=${APP_NAME}
VERSION=$1

source "../../../../ssh-production.sh" 

if [ ! -n "${VERSION}" ]; then
  echo "Usage: ./build.sh version "
  echo "version is docker image version"
  exit 1
fi

cd ../../../

cd APP-META/docker-config/

echo "复制需要包含的 jdk,sunfire,key,i18n等 on jump machine ${JUMP_USER}@${JUMP_MACHINE}"
ssh -i ${JUMP_CERT} -t ${JUMP_USER}@${JUMP_MACHINE} "mkdir -p /home/admin/${APP_NAME}/dev-base/; \
    cp /home/admin/resources/taobao-hsf.tgz /home/admin/${APP_NAME}/dev-base; \
    cp /home/admin/resources/sunfire/crontabs-1.11.rpm /home/admin/${APP_NAME}/dev-base; \
    cp /home/admin/resources/sunfire/cronie-1.4.11.rpm /home/admin/${APP_NAME}/dev-base; \
    cp /home/admin/resources/sunfire/start-sunfire.sh /home/admin/${APP_NAME}/dev-base; \
    cp /home/admin/resources/sunfire/tsar-2.1.33-1568425.82ced85.el7.x86_64.rpm /home/admin/${APP_NAME}/dev-base; \
    cp /home/admin/resources/sunfire/sunfire-agent-1.0.10-20190916175607.noarch.rpm /home/admin/${APP_NAME}/dev-base; \
    cp /home/admin/resources/jdk/ajdk-8_3_6-b129-8.3.6-1207912.alios7.x86_64.rpm /home/admin/${APP_NAME}/dev-base "
    
echo "scp package scp -i ${JUMP_CERT} -r ./dev-base/  ${JUMP_USER}@${JUMP_MACHINE} " 
scp -i ${JUMP_CERT} -r ./dev-base/  ${JUMP_USER}@${JUMP_MACHINE}:/home/admin/${APP_NAME}/
scp -i ${JUMP_CERT} -r ./environment/  ${JUMP_USER}@${JUMP_MACHINE}:/home/admin/${APP_NAME}/

echo "exec : docker build on ${JUMP_USER}@${JUMP_MACHINE} --build-arg APP_NAME=${APP_NAME} --build-arg APPID=${APPID} --pull -f Dockerfile_base -t registry-vpc.cn-north-2-gov-1.aliyuncs.com/${NAMESPACE}/${REPO}:${VERSION} ."
ssh -i ${JUMP_CERT} -t ${JUMP_USER}@${JUMP_MACHINE} "cd /home/admin/${APP_NAME}/;sudo docker build --build-arg APPNAME=${APP_NAME} --build-arg  --pull -f ./dev-base/Dockerfile_base -t registry-vpc.cn-north-2-gov-1.aliyuncs.com/${NAMESPACE}/${REPO}:${VERSION} ."

echo "exec : docker push registry-vpc.cn-north-2-gov-1.aliyuncs.com/${NAMESPACE}/${REPO}:${VERSION}"
ssh -i ${JUMP_CERT} -t ${JUMP_USER}@${JUMP_MACHINE} "cd /home/admin/${APP_NAME}/;sudo docker push registry-vpc.cn-north-2-gov-1.aliyuncs.com/${NAMESPACE}/${REPO}:${VERSION}"

echo "docker push done"
