docker基于ubuntu镜像自动化部署war

环境

docker：Docker version 17.11.0-ce
ubuntu: 14.04
java: 8
tomcat: 7

docker化，并上传至harbor

1. Dockerfile

    FROM ubuntu:14.04
   
    MAINTAINER    xiaojie
    
    ADD jdk-8u71-linux-x64.tar.gz /usr/local/
    
    ADD apache-tomcat-7.0.70.tar.gz  /usr/local/
    
    ADD  tomcat-users.xml /usr/local/apache-tomcat-7.0.70/conf/
    
    ADD  settings.xml /usr/local/apache-tomcat-7.0.70/conf/
    
    ADD  demo.war /usr/local/apache-tomcat-7.0.70/webapps/
    
    ENV JAVA_HOME /usr/local/jdk1.8.0_71
    
    ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
    
    ENV CATALINA_HOME /usr/local/apache-tomcat-7.0.70
    
    ENV CATALINA_BASE /usr/local/apache-tomcat-7.0.70
    
    ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/lib:$CATALINA_HOME/bin
    
    EXPOSE 8080
    
    ENTRYPOINT ["/usr/local/apache-tomcat-7.0.70/bin/catalina.sh", "run" ]

2. tomcat-users.xml

<?xml version='1.0' encoding='utf-8'?>

  <tomcat-users>
    <role rolename="manager-gui"/>
     <role rolename="manager-script"/>
        <user username="demo" password="demo11111"                                   roles="manager-gui,manager-script"/>
    </tomcat-users>

1. settings.xml

    <?xml version="1.0"encoding="UTF-8"?><settings><servers>
    <server>
        <id>TomcatServer</id>
        <username>demo</username>
        <password> demo11111</password>
    </server></servers></settings>

1. build, run

    docker stop demo-container
    docker rm demo-container
    docker build -t demo/tomcat .
    docker run --name demo-container -d -p 8080:8080 demo/tomcat

2. push之前需要将harbor地址加入到信任中，vi /etc/default/docker

   DOCKER_OPTS="$DOCKER_OPTS --insecure-registry ...:8888"

3. push至私有harbor库

    docker login -u demo -p password123   **.**.**.**:8888
    docker tag demo/tomcat **.**.**.**:8888/demo/tomcat
    docker push **.**.**.**:8888/demo/tomcat

坑点

1. 保持tomcat版本、java版本和开发环境一样，不然可能会有莫名的问题
