用Dockerfile創建tomcat鏡像

用Dockerfile創建tomcat鏡像

1.準備軟件

1. jdk 例如：jdk-8u211-linux-x64.tar.gz
2. tomcat 例如：apache-tomcat-8.5.42.tar.gz

2.創建Dockerfile文件

#pull down centos image
FROM centos
#maintainer
MAINTAINER junpeng li
#copy jdk and tomcat into image
ADD ./software/apache-tomcat-8.5.42.tar.gz /root
ADD ./software/jdk-8u211-linux-x64.tar.gz /root
#set environment variable
ENV JAVA_HOME /root/jdk1.8.0_211
ENV PATH $JAVE_HOME/bin:$PATH
#define entry point which will be run first when the container starts up
ENTRYPOINT /root/apache-tomcat-8.5.42/bin/startup.sh && tail -F /root/apache-tomcat-8.5.42/logs/catalina.out
#port
EXPOSE 8080

Dockerfile文件在此不做過多解釋

3.文件目錄結構

tomcat-linux

├── Dockerfile
└── software
    ├── apache-tomcat-8.5.42.tar.gz
    └── jdk-8u211-linux-x64.tar.gz

4.編譯docker鏡像

1. 輸入命令 docker build -t [your docker repository]/tomcat-centos:latest --rm=true .

docker build -t [your docker repository]/tomcat-centos:latest --rm=true .

3. 上傳鏡像

docker push [your docker repository]/tomcat-centos:latest

控制檯輸出信息

The push refers to a repository [docker.io/[your docker repository]/tomcat-centos]
2eba6206d8f3: Pushed 
796f67795dd7: Pushed 
d69483a6face: Layer already exists

4. 登錄docker鏡像管理網站查看
   
5. 運行鏡像 docker run -it [your docker repository]/tomcat-centos -port 8090:8080

docker run -it [your docker repository]/tomcat-centos -port 8090:8080
