Use Docker to build a Web server for CentOS 7 + Tomcat 7 + Oracle JDK 7

Scenario One: Use wget to download the latest version of Tomcat build when Docker is created

# centos 7 + oracle  jdk 7 + tomcat 7   from  centos:centos7    MAINTAINER yuj <[email protected]>        run yum install -y  java-1.7.0-openjdk.x86_64  wget tar    env tomcat_major_version 7    env  tomcat_minor_version 7.0.63    workdir /opt/    run  wget -o /opt/tomcat7.tar.gz  http://www.us.apache.org/dist/tomcat/tomcat-7/v${tomcat _minor_version}/bin/apache-tomcat-${tomcat_minor_version}.tar.gz  -q && \          tar -xzf /opt/tomcat7.tar.gz && \          rm /opt/tomcat7.tar.gz && \          ln -s apache-tomcat-$TOMCAT _minor_version tomcat    add  create_tomcat_admin_user.sh  /opt/create_tomcat_admin_user.sh    ADD  start.sh /opt/start.sh    env catalina_home /opt/tomcat     expose 8080    cmd ["/opt/start.sh"]

Scenario Two: Build with the Tomcat compression package downloaded on the Docker server (apache-tomcat-7.0.63.tar.gz is used here)

# centos 7 +  oracle  jdk 7 + tomcat 7     from centos:centos7    maintainer yuj <[email protected ]>       run yum install -y   java-1.7.0-openjdk.x86_64 wget tar    env tomcat_major_version 7     ENV TOMCAT_MINOR_VERSION 7.0.63    ADD  Apache-tomcat-7.0.63.tar.gz /opt/    workdir /opt/    run  ln -s  apache-tomcat-$TOMCAT _minor_version tomcat    add  create_tomcat_admin_user.sh  /opt/create_tomcat_admin_user.sh    add  start.sh /opt/start.sh    env catalina_home /opt/tomcat     expose 8080    cmd ["/opt/stArt.sh "]
