1. Make JAVA running environment image

My basic image is based on the official website centos 7.2.It can not be downloaded in advance.

# docker pull docker.io/centos

[root@R210] # mkdir-p / opt/Dockerfile/JRE1.7

[root@R210 ~] # cd / opt/Dockerfile/JRE1.7

[root@R210 jre1.7] # ls

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

[root@R210 jre1.7] # cat Dockerfile

FROM centos:latest

two。 Make Tomcat image of production environment

[root@R210] # mkdir-p / opt/Dockerfile/tomcat7

[root@R210 ~] # cd / opt/Dockerfile/tomcat7

[root@R210 tomcat7] # ls

Apache-tomcat-7.0.70.tar.gz Dockerfile

[root@R210 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 a mirror image

[root@R210 tomcat7] # docker build-t tomcat7:7.0.70.

Launch a tomcat container from the image, deploy the test program to / www/app1/webapps and access it from the browser

[root@R210] # docker run-d-p 8002 name mytomcat7 8080-- name mytomcat7-v / www/app1/webapps/:/tomcat/webapps tomcat7:7.0.70

3. Make database mariadb mirror

[root@XSMM mk_mariadb] # ls

Dockerfile mariadb-func.sh mariadb.repo run.sh

[root@XSMM-WEB mk_mariadb] # cat Dockerfile
