现在学习下以Dockerfile自定义image,以tomcat8.0.50为例
1. 编写Dockerfile
cd /apps/dockerbuilder/tomcat8.0.50 && vim dockerfile
# bash image
FROM harbor.nedy.com/atlas/centos7.5-base:7.5.1804
MAINTAINER lv "[email protected]"
# update source
# yum update -y
# Install JDK 8
RUN cd /tmp && curl -O -s download.nedy.com/jdk1.8.0_65.tar.gz && tar xf jdk1.8.0_65.tar.gz -C /usr/local/
ENV JAVA_HOME /usr/local/jdk1.8.0_65
ENV PATH $PATH:/$JAVA_HOME/bin
# Install tomcat8
RUN cd /tmp && curl -O -s download.nedy.com/apache-tomcat-8.0.50.tar.gz && tar xf apache-tomcat-8.0.50.tar.gz && mv apache-tomcat-8.0.50 /usr/local/tomcat
# Add tomcat.sh
ADD tomcat /etc/init.d/tomcat
RUN chmod 755 /etc/init.d/tomcat
# Expose ports
EXPOSE 8080
# Define default command
#ENTRYPOINT cd /usr/local/tomcat/bin && ./startup.sh
CMD /etc/init.d/tomcat start && tail -f /usr/local/tomcat/logs/catalina.out
*注释
? harbor.nedy.com 是我自己的私有镜像服务器地址
? download.nedy.com 是我自己的文件服务器地址
? harbor.nedy.com/atlas/centos7.5-base:7.5.1804 Centos7.5 系统基础镜像
2. tomcat启动文件
cat /apps/dockerbuilder/tomcat8.0.50 /tomcat
#!/bin/bash
export JAVA_HOME=/usr/local/jdk1.8.0_65
export TOMCAT_HOME=/usr/local/tomcat
case $1 in
start)
sh $TOMCAT_HOME/bin/startup.sh
;;
stop)
sh $TOMCAT_HOME/bin/shutdown.sh
;;
restart)
sh $TOMCAT_HOME/bin/shutdown.sh
sh $TOMCAT_HOME/bin/startup.sh
;;
esac
exit 0
3. 验证 Dockerfie
执行 Dockerfie
docker build -t harbor.nedy.com/atlas/tomcat8-jdk8 /apps/dockerbuilder/tomcat8.0.50/
这里我直接加上我的私有镜像服务器标签
启动容器并查看tomcat日志
Docker run -it -p 8888:8080 --name tomcat8.0.50 harbor.nedy.com/atlas/tomcat8-jdk8
参数说明：
-d 后台运行
-it 前台交互式运行
-p 8888:8080 将宿主机的8888端口映射到容器的8080端口
—name tomcat8.0.50 给容器命名为tomcat8.0.50
浏览器访问
http://10.180.160.113:8888
4.上传到镜像服务器上
docker push harbor.nedy.com/atlas/tomcat8-jdk8
