Using docker to build tomcat environment

1. create a directory

[root@ticent docker]#mkdir /home/docker

2. Download tomcat

[root@ticent docker]#wget http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.0.45/bin/apache-tomcat-8.0.44.tar.gz

3. Download jdk

[root@ticent docker]# wget http://download.oracle.com/otn-pub/java/jdk/8u131-b11/d54c1d3a095b4ff2b6607d096fa80163/jdk-8u131-linux-x64.tar.gz

4. Extract to current directory

5. Edit Dockerfile

[root@ticent docker]#vi Dockerfile

Click here to fold or open

FROM centos:latest

#install jdk

ADD jdk1.8.0_131 /opt/jdk8

ENV JAVA_HOME /opt/jdk8

ENV PATH $PATH:$JAVA_HOME/bin

RUN mkdir -p "$JAVA_HOME"

#install tomcat

ADD tomcat8 /opt/tomcat8

ENV CATALINA_HOME /opt/tomcat8

ENV PATH $CATALINA_HOME/bin:$PATH

RUN mkdir -p "$CATALINA_HOME"

WORKDIR $CATALINA_HOME

EXPOSE 8080

CMD ["catalina.sh", "run"]

6. Local centos mirror, here centos:latest

7. build images

[root@ticent docker]# docker build -t tomcat8 .

8. Start, tomcat port mapped to 18080

[root@ticent docker]# docker run -d -p 18080:8080 tomcat8

9. View docker progress

[root@ticent docker]# docker ps

10. Visit tomcat

11. into the container

docker exec -it 65f238010b2c /bin/bash

12. In this article, we use centos mirror to manually build jdk and tomcat into the mirror, which makes it easier to customize the runtime environment.
