制作基于 apline 的 jdk11 环境
制作基于 apline 的 jdk11 环境
没有搞定的方法：

以上两种方法都试过了，没有成功。也不想深究原因了，主要是执行到 RUN 命令时报错：
Step 4/10 : ADD openjdk-11.0.2_linux-x64_bin.tar.gz .
---> e689709810fd
Step 5/10 : RUN echo http://mirrors.aliyun.com/alpine/v3.10/main/ > /etc/apk/repositories && echo http://mirrors.aliyun.com/alpine/v3.10/community/ >> /etc/apk/repositories
---> Running in c95b21a59983

使用这里介绍的办法：https://www.coder.work/article/7507519
docker run -it alpine:3.11
# apk add openjdk11 安装 openjdk11的命令，类似于centos 的 yum install
# java -version
openjdk version "11.0.5" 2019-10-15
OpenJDK Runtime Environment (build 11.0.5+10-alpine-r0)
OpenJDK 64-Bit Server VM (build 11.0.5+10-alpine-r0, mixed mode)
先拉取镜像 alpine:3.11，并启动一个容器，进入该容器，安装 openjdk11，这里应该是可以通过将下载的jdk11相关tar.gz复制到容器中，然后配置好环境变量，目的是可以全局访问 JAVA_HOME 的bin 目录，最好配置以下的环境变量
ENV JAVA_HOME=/cpc_docker/jdk/jdk1.8.0_221
ENV CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
ENV PATH=$JAVA_HOME/bin:$PATH
将该容器提交为一个镜像
docker rename jovial_jepsen apline-openjdk11
docker commit -m '自己制作的apline-openjdk11奖项(描述信息)' -a '作者信息' apline-openjdk11 apline-openjdk11:1.0
将该镜像作为基础镜像打包新镜像的时候
# 设置基准镜像
FROM cumtsgw/alpine-openjdk11:v1.0 AS BUILD
# FROM 8feb2cdbcb55 AS BUILD
# 维护者
MAINTAINER nickel cumtsgw@163.com
# 将指定的文件或者目录复制到镜像的指定目录中
ADD . /server
WORKDIR /server
ENV dir="hello"
ENV rtsp="hello"
# 启动端口
EXPOSE 8080
# 容器运行后默认将要执行jar包的命令
ENTRYPOINT ["sh", "-c", "java -jar demo-0.0.1-SNAPSHOT.jar --rtsp=${rtsp} --dir=${dir}"]
FROM 后面的镜像，不能是本地镜像，起码是要从仓库下载，下载过一次之后，后面打包是否还要下载就不知道了。
如果考虑使用本地镜像作为基础镜像，而仓库里没有的时候，会报错：
