背景说明

每次临近重要日子
各种境外网站都会嗝屁

没办法, 同事又要求进行一下xc设备的镜像验证
我这边先找同事帮忙要了一个base images 
然后进行了一些相关的处理

私有镜像库的public镜像

registry.xxxxx.com/public/docker.io/library/eclipse-temurin:8-jdk
同事告知, 现在建议使用这个 eclipse-temurin 
比较适合生产环境的运行. 

AdoptOpenJDK最高只到16，是没有更新吗？了解了一下，
原来是AdoptOpenJDK被废弃了，那该怎么办呢？
这就要提到Eclipse基金会旗下的ADOPTIUM了，
它是一个发布二进制安装包的项目，而OpenJDK的发行版也被其囊括在内。
AdoptOpenJDK从长远考虑，加入到ADOPTIUM，成为Eclipse Temurin。
它被设定为用于苛刻的生产环境，换句话说AdoptOpenJDK改名了，
叫做Eclipse Temurin。

打包镜像的快速方法

FROM registry.xxxxxx.com/public/docker.io/library/eclipse-temurin:8-jdk
WORKDIR app
COPY gscloud app
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-Dloader.path=./server/runtime/3rd,./server/runtime/libs", \
"-Dparallel.startup=true","-Dserver.runtime.path.name=server","-XX:+UseContainerSupport","-XX:MaxRAMPercentage=75.0", \
"-XX:InitialRAMPercentage=75.0","-XX:MinRAMPercentage=75.0","-XX:+DisableExplicitGC","-XX:+PrintGC","-XX:+PrintGCDateStamps", \
"-XX:+PrintGCDetails","-XX:+PrintGCTimeStamps","-Xloggc:/app/dump/gclog","-XX:+HeapDumpOnOutOfMemoryError",\
"-XX:HeapDumpPath=/app/dump","-jar","./server/runtime/caf-bootstrap.jar","--spring.config.location=./server/runtime/"]

打包镜像

docker build . -t baseimages:01

分层打包的快速方法

FROM baseimages:01
COPY application.yaml app/server/runtime/application.yaml
ENV  TZ=Asia/Shanghai
WORKDIR app
ADD myfonts.tar.gz      usr/share/fonts/
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-Dloader.path=./server/runtime/3rd,./server/runtime/libs", \
"-Dparallel.startup=true","-Dserver.runtime.path.name=server","-XX:+UseContainerSupport","-XX:MaxRAMPercentage=75.0", \
"-XX:InitialRAMPercentage=75.0","-XX:MinRAMPercentage=75.0","-XX:+DisableExplicitGC","-XX:+PrintGC","-XX:+PrintGCDateStamps", \
"-XX:+PrintGCDetails","-XX:+PrintGCTimeStamps","-XX:+HeapDumpOnOutOfMemoryError","-XX:+PrintGCCause","-XX:+PrintGCApplicationStoppedTime",\
"-XX:HeapDumpPath=/app/dump","-jar","./server/runtime/caf-bootstrap.jar","--spring.config.location=./server/runtime/"]

分层打包第二层

docker build . -t baseimages:02

说明, 可以修改配置文件进行注入, 这样基于基础镜像可以实现微服务的拆分.
