Docker：制作镜像上传阿里云
1、准备要上传镜像的材料
apache-tomcat-8.5.83.tar.gz
jdk-8u202-linux-x64.tar.gz
jdk 和Tomcat自己去官网下载
2、编写Dockerfile 文件
# 基础镜像
FROM ubuntu
# 描述
MAINTAINER jdk_comcat:8
# 解压与复制jdk.tar.gz
# 由于add/copy的文件必须使用上下文目录的内容, 因此要先将jdk.tar.gz拷贝到当前目录
ADD jdk-8u202-linux-x64.tar.gz /usr/local
ADD apache-tomcat-8.5.83.tar.gz /usr/local
# 配置 JDK 的环境变量和字符集
ENV JAVA_HOME /usr/local/jdk1.8.0_202
ENV PATH $JAVA_HOME/bin:$PATH
ENV CLASSPATH .:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
ENV LANG C.UTF-8
# 配置tomcat环境变量
ENV CATALINA_HOME /usr/local/apache-tomcat-8.5.83
ENV CATALINA_BASE /usr/local/apache-tomcat-8.5.83
ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/lib:$CATALINA_HOME/bin
# 暴露端口
EXPOSE 8080
# 启动tomcat -- 最后的命令要一直运行下去，以防容器退出
ENTRYPOINT /usr/local/apache-tomcat-8.5.83/bin/startup.sh && tail -f /usr/local/apache-tomcat-8.5.83/logs/catalina.out
3、构建镜像
采用docker build 指令构建jdk_tomcat:8指定的版本：
[root@localhost tomcat]# sudo docker build -t jdk_tomcat:8 .
Sending build context to Docker daemon 204.7MB

Removing intermediate container ad6353686b35
---> fa0bafc06889
Successfully built fa0bafc06889
Successfully tagged jdk_tomcat:8
4、启动当前镜像
通过docker run 启动jdk_tomcat:8 当前镜像
sudo docker run -itd -p 8080:8080 --name jdk_tomcat jdk_tomcat:8
启动成功后，通过 docker images 查看镜像。
通过docker ps查看容器：
[root@localhost tomcat]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
1faae7d0ce90 jdk_tomcat:8 "/bin/sh -c '/usr/lo…" 4 seconds ago Up 3 seconds 0.0.0.0:8080->8080/tcp, :::8080->8080/tcp jdk_tomcat
8e97133ab2de gitlab/gitlab-ce "/assets/wrapper" 30 hours ago Up 29 minutes (healthy) 80/tcp, 0.0.0.0:8090->8090/tcp, :::8090->8090/tcp, 0.0.0.0:8022->22/tcp, :::8022->22/tcp, 0.0.0.0:8443->443/tcp, :::8443->443/tcp gitlab
5、准备阿里云账号
5.1、创建镜像仓库：
5.2、选择本地仓库创建镜像库
5.3、在客户端登陆阿里云
通过docker login 登陆
docker login --username=*** registry.cn-hangzhou.aliyuncs.com
输入自己的密码：
问题：Error response from daemon: Get “https://registry.cn-hangzhou.aliyuncs.com/v2/”: unauthorized: authentication required
解决方法：
1、不要使用第三方授权登陆，自己注册一个阿里云账号
2、修改DNS存值。
[root@localhost tomcat]# vi /etc/resolv.conf
# Generated by NetworkManager
search localdomain
nameserver 192.168.220.2
保证DNS 存在值
5.4 添加标签和推送
通过docker images 获取镜像ID，然后通过阿里给的指令推送：
$ docker tag [ImageId] registry.cn-hangzhou.aliyuncs.com/lskdxhl/jdk_comcat:[镜像版本号]
$ docker push registry.cn-hangzhou.aliyuncs.com/lskdxhl/jdk_comcat:[镜像版本号]
[root@localhost tomcat]# docker tag fa0bafc06889 registry.cn-hangzhou.aliyuncs.com/lskdxhl/jdk_comcat:8
[root@localhost tomcat]# docker push registry.cn-hangzhou.aliyuncs.com/lskdxhl/jdk_comcat:8
The push refers to repository [registry.cn-hangzhou.aliyuncs.com/lskdxhl/jdk_comcat]
032714f94ad3: Pushed
4e3b53d854a6: Pushed
9f54eef41275: Pushed
8: digest: sha256:68b03cdf1d81b57489b7bf6de2761d7c0cce826e85c31a93fe11a029b3a21eb5 size: 954
5.5 查看和拉取
查看阿里云镜像仓库：
拉取上传的镜像：
sudo docker pull registry.cn-hangzhou.aliyuncs.com/lskdxhl/jdk_comcat:8
6、制作JDK 镜像
同理制作JDK镜像，添加jar包，测试jdk镜像是否成功：
docker run -d --name eureka-9001 --privileged=true --network host --restart always -w /usr/eureka/ -v /data/eureka:/usr/eureka registry.cn-hangzhou.aliyuncs.com/lskdxhl/jdk_li:8 /bin/sh -c 'sh start.sh'
成功启动Eureka:
