Making Docker Images

1, make the Java running Environment image

My base image is based on the official CentOS 7.2 version of the website, no advance download is possible.

#docker Pull Docker.io/centos

[Email protected] ~]# mkdir-p/opt/dockerfile/jre1.7

[Email protected] ~]# cd/opt/dockerfile/jre1.7

[[email protected] jre1.7]# ls

Dockerfile server-jre-7u80-linux-x64.tar.gz

[email protected] jre1.7]# cat Dockerfile

From Centos:latest

2. Making production environment Tomcat image

[Email protected] ~]# mkdir-p/OPT/DOCKERFILE/TOMCAT7

[Email protected] ~]# CD/OPT/DOCKERFILE/TOMCAT7

[[email protected] tomcat7]# ls

Apache-tomcat-7.0.70.tar.gz Dockerfile

[email protected] tomcat7]# cat Dockerfile

from java7:7u80maintainer yyenv tomcat_version 7.0.70env catalina_home / tomcatenv app_dir ${catalina_home}/webapps/run rpm --rebuilddb      && yum --setopt=tsflags=nodocs -y install     apr  tomcat-native     && rm -rf /var/cache/yum/* & & yum clean all#run wget -q https://archive.apache.org/dist/tomcat/tomcat-${ tomcat_major_version}/v${tomcat_minor_version}/bin/apache-tomcat-${tomcat_minor_version}.tar.gz#https:// archive.apache.org/dist/tomcat/tomcat-7/v7.0.70/bin/apache-tomcat-7.0.70.tar.gzcopy apache-tomcat-${ tomcat_version}.tar.gz apache-tomcat-{tomcat_version}.tar.gzrun tar zxf apache-tomcat-*. tar.gz &&     rm apache-tomcat-*.tar.gz &&      mv apache-tomcat* tomcat &&     rm -rf tomcat/webapps/* &&      sed -i  '/protocol= ' ajp\/1.3 '/d '  /tomcat/conf/server.xml     expose 8080 entrypoint ["/tomcat/bin/catalina.sh", "Run"]ONBUILD ADD  . ${app_dir}

Make image

[[email protected] tomcat7] #docker build-t tomcat7:7.0.70.

Launches a Tomcat container from the mirror, deploys the test program to/www/app1/webapps and accesses it from the browser
