Docker Deployment Project - Demo tomcat

0. Relevant File

• apache-tomcat-9.0.73.tar.gz
• jdk-8u361-linux-x64.tar.gz

1. Write Dockerfile

We will place the apache-tomcat-9.0.73.tar.gz and jdk-8u361-linux-x64.tar.gz files in the same folder.
And in this folder, write the Dockerfile file, with the specific configuration as follows:

FROM centos:7
MAINTAINER hardyhu<1243971719@qq.com>

COPY readme.txt /usr/local/readme.txt

ADD jdk-8u361-linux-x64.tar.gz /usr/local/
ADD apache-tomcat-9.0.73.tar.gz /usr/local/

RUN yum -y install vim

ENV MYPATH /usr/local
WORKDIR $MYPATH

ENV JAVA_HOME /usr/local/jdk1.8.0_361
ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
ENV CATALINA_HOME /usr/local/apache-tomcat-9.0.73
ENV CATALINA_BASH /usr/local/apache-tomcat-9.0.73
ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/lib:$CATALINA_HOME/bin

EXPOSE 8080

CMD /usr/local/apache-tomcat-9.0.73/bin/startup.sh && tail -F /usr/local/apache-tomcat-9.0.73/logs/catalina.out

You can view additional help information in the Dockerfile Help.

Tip: To specify a configuration file other than Dockerfile, you must use the -f option to provide the file name.

2. Build and Run

2.1 Build Image:

docker build -t diytomcat .

The -t represents a tag.

You can view more help information on the build command document.

2.2 Run Container:

docker run -d -p 9091:8080 --name hardyhutomcat -v /home/hardyhu/build/tomcat/test:/usr/local/apache-tomcat-9.0.73/webapps/test -v /home/hardyhu/build/tomcat/tomcatlogs/:/usr/local/apache-tomcat-9.0.73/logs diytomcat

The -d represents running the container in the background and printing its container ID.
