前提：準(zhǔn)備好基礎(chǔ)Tomcat鏡像，準(zhǔn)備一個(gè)制作鏡像的目錄

1.準(zhǔn)備tomcat需要的xml文件

xxx.xml

<Context path="/xxx" docBase="/opt/product/apps/xxx" workDir="/opt/product/data/works/xxx">
<Resources allowLinking="true"/>
</Context>

2.打包好應(yīng)用代碼 部署文件

apps
這個(gè)目錄下為應(yīng)用文件

3.編寫all.sh文件

這里路徑都是容器里的路徑，將配置文件,日志目錄軟鏈接到掛載目錄，方便修改，可持續(xù)化

#!/bin/bash

export JAVA_HOME=/data/jdk
export PATH=$JAVA_HOME/bin:$PATH

logsDir="/opt/product/data/logs/tomcat-epg"

cd /opt/product/apps/xxx/WEB-INF/conf/
rm -rf config.properties
ln -s /opt/product/xxx/configs/config.properties config.properties

cd /opt/product/apps/xxx/WEB-INF/classes/
rm -rf log4j.properties
ln -s /opt/product/data/configs/log4j.properties log4j.properties

cd /opt/product/apps/xxx/
rm -rf files
ln -s /opt/product/data/xxx-data files

cd /opt/product/tools/tomcat/
rm -rf logs
if [ ! -d $logsDir ]; then
   mkdir -p $logsDir
fi

ln -s /opt/product/data/logs/tomcat-epg /opt/product/tools/tomcat/logs

sh /opt/product/tools/tomcat/bin/catalina.sh run

4.編寫Dockerfile文件

FROM tomcat:v1.0
MAINTAINER gudolf
VOLUME [ "/opt/product/data" ]
ADD xxx.xml /opt/product/tools/tomcat/conf/Catalina/localhost/
ADD ./apps/ /opt/product/apps/
WORKDIR /opt/product/tools/tomcat/bin
ADD all.sh /root/
RUN chmod +x /root/all.sh
ENTRYPOINT ["/root/all.sh"]
CMD ["/usr/sbin/init"]

5.制作鏡像

sudo docker build -t xxx:xxx  ./

6.啟動(dòng)鏡像

sudo docker run --name=xxx -d -ti -p 8080:8080 -v /opt/product/data/xxx:/opt/product/data -v /data/jdk:/data/jdk xxx:xxx
