I believe many inexperienced people don't know what to do about how to use dockerfile in docker. Therefore, this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Copy the downloaded JDK to the server scp / jdk path / location where the jdk-8u211-linux-x64.tar.gz ubuntu@ server IP:/ writes the dockerfile / docker-centos-vim write dockerfile# Select the basic image I choose UbuntuFROM ubuntu:tag # tag as the version # add maintainer information LABEL version= "1.0" # version LABEL description= "this is an Image for Springboot application" # basic description LABEL maintainer= "haoyuehong91@163.com" # Maintainer Information # configure JDK# 1. Why do you use ADD instead of COPY inside the JDK ADD container on the host? because ADD decompresses and JDK is better to configure the environment variable ENV JAVA_HOME / soft/jdk1.8.0_211ENV JRE_HOME ${JAVA_HOME} / jreENV CLASSPATH.: ${JAVA_HOME} / lib:$ {JAR_HOME} / libENV PATH ${M2_HOME} / bin in the same directory as dockerfile. PATH# COPY the project jar package into the container with COPY because it will not unzip the COPY admin-0.0.1-SNAPSHOT.jar / app/# exposed port EXPOSE 900 switch to the working directory WORKDIR / app/# run the jar package # ENTRYPOINT ["java" "- jar", "/ app/admin-0.0.1-SNAPSHOT.jar"] or shell ENTRYPOINT nohub java-jar admin-0.0.1-SNAPSHOT.jar& to create an image docker build-t image_name.

Don't forget the rest.

Image_name is the name of the mirror

Build the container docker run-d-- name container-p 9000 image_nmae 8000 image_nmae

-d represents the daemon if you want to change-d to-it interactively

-- name is followed by a custom name

-p port mapping above means to map port 8000 in the container to port 9000 of the host
