Docker containerized deployment of springboot projects

One, make the smallest jdk mirror

1、下载jre8:https://www.java.com/en/download/manual.jsp

2. Delete redundant files

a. Unzip the compressed package

$ tar -xvcf jre-8u181-linux-x64.tar.gz

b, delete redundant files

$ cd jre1.8.0_181/
$ rm -rf COPYRIGHT LICENSE README release THIRDPARTYLICENSEREADME-JAVAFX.txt THIRDPARTYLICENSEREADME.txt Welcome.html
$ rm -rf   lib/plugin.jar \
           lib/ext/jfxrt.jar \
           bin/javaws \
           lib/javaws.jar \
           lib/desktop \
           plugin \
           lib/deploy* \
           lib/*javafx* \
           lib/*jfx* \
           lib/amd64/libdecora_sse.so \
           lib/amd64/libprism_*.so \
           lib/amd64/libfxplugins.so \
           lib/amd64/libglass.so \
           lib/amd64/libgstreamer-lite.so \
           lib/amd64/libjavafx*.so \
           lib/amd64/libjfx*.so

c, repack

$ tar zcvf jre8.tar.gz *

3. Write Dockerfile (place jre8.tar.gz and Dockerfile in the same directory)

FROM docker.io/jeanblanchard/alpine-glibc
MAINTAINER micheal
ADD jre8.tar.gz /usr/java/jdk/
ENV JAVA_HOME /usr/java/jdk
ENV PATH ${PATH}:${JAVA_HOME}/bin
WORKDIR /opt

4. Build a mirror

$docker build -t jdk1.8-mini:v1 .

Note: The image built according to this method will have the problem of Chinese garbled characters. Refer to the solution: https://blog.csdn.net/zhuchuanwan/article/details/102957332 ; if you don’t pay attention to the problem of Chinese garbled characters, you can use it directly. 

Second, build the springboot project image

1. Type the springboot project into a jar package

2. Write Dockerfile (place jre8.tar.gz and search-demo.jar in a unified directory)

FROM docker.io/jeanblanchard/alpine-glibc
MAINTAINER simon
ADD jre8.tar.gz /usr/java/jdk/
ENV JAVA_HOME /usr/java/jdk
ENV PATH ${PATH}:${JAVA_HOME}/bin
WORKDIR /opt
ADD search-demo.jar .
ENTRYPOINT ["java","-jar","./search-demo.jar"]

3. Build a mirror

$docker build -t demo:v2 .

Three, start the mirror

1. Start

docker run -d -p 8082:8080 demo:v2 sh

2. View the startup result

$docker ps -a

Successful startup:
