站長資訊網(wǎng)退到tomcat目錄下，新建兩個業(yè)務用的目錄文件
[root@node6 /data/dockerfile/web/tomcat/tomcat-base]#cd ..
[root@node6 /data/dockerfile/web/tomcat]#mkdir tomcat-app1
[root@node6 /data/dockerfile/web/tomcat]#mkdir tomcat-app2
進入Tomcat-app1目錄下創(chuàng)建Dockerfile文件
[root@node6 /data/dockerfile/web/tomcat]#cd tomcat-app1
[root@node6 /data/dockerfile/web/tomcat/tomcat-app1]#vim Dockerfile

LABEL maintainer "mr.luo "
RUN mkdir -p /data/tomcat/webapps/myapp && useradd tomcat
ADD index.html /data/tomcat/webapps/myapp
ADD run_tomcat.sh /apps/tomcat/bin/run_tomcat.sh
COPY server.xml /apps/tomcat/conf/server.xml
RUN chown -R tomcat.tomcat /apps /data/tomcat/webapps
EXPOSE 8080
CMD ["/apps/tomcat/bin/run_tomcat.sh"]
創(chuàng)建測試文件
[root@node6 /data/dockerfile/web/tomcat/tomcat-app1]#vim index.html
tomcat testapp1
拷貝server.xml文件到當前目錄下。
[root@node6 /data/dockerfile/web/tomcat/tomcat-app1]#cp /usr/local/apache-tomcat-8.5.33/conf/server.xml ./
編輯server.xml文件修改host的路徑
[root@node6 /data/dockerfile/web/tomcat/tomcat-app1]#vim server.xml
創(chuàng)建tomcat啟動腳本、并給腳本添加執(zhí)行權(quán)限
[root@node6 /data/dockerfile/web/tomcat/tomcat-app1]#vim run_tomcat.sh
#!/bin/bash
echo "1.1.1.1 abc.test.com" >> /etc/hosts
echo "nameserver 223.5.5.5" > /etc/resolv.conf
su – tomcat -c "/apps/tomcat/bin/catalina.sh start"
su – tomcat -c "tail -f /etc/hosts"
# 給腳本添加執(zhí)行權(quán)限
[root@node6 /data/dockerfile/web/tomcat/tomcat-app1]#chmod +x run_tomcat.sh
創(chuàng)建docker build 腳本
[root@node6 /data/dockerfile/web/tomcat/tomcat-app1]#vim build-command.sh
#!/bin/bash
# Dockerfile build shell
docker build -t 172.20.7.50/baseimages/centos-tomcat-web:app1 .

啟動剛制作好的鏡像，測試tomcat是否制作成功
[root@node6 /data/dockerfile/web/tomcat/tomcat-app1]#docker run –name tom1 -it -d -p 8801:8080 172.20.7.50/baseimages/centotomcat-web:app1
6b77dd85d8a74b7475bd3340e501d3bcd0019ffdad2ea0505ca371f52c3d2ae6

制作第二個就非常簡單了只需要在第一個上面改下名稱即可
先拷貝tomcat-app1下所有文件到tomcat-app2下即可
[root@node6 /data/dockerfile/web/tomcat/tomcat-app1]# cd ..
[root@node6 /data/dockerfile/web/tomcat]#cp -rf tomcat-app1/* tomcat-app2/
修改index.html標識為tomcat testapp2即可
[root@node6 /data/dockerfile/web/tomcat/tomcat-app2]#vim index.html
tomcat testapp2
修改docker build腳本centos-tomcat-web:app1改成centos-tomcat-web:app2即可，表示這是app2的鏡像
[root@node6 /data/dockerfile/web/tomcat/tomcat-app2]#vim build-command.sh
#!/bin/bash
# Dockerfile build shell
docker build -t 172.20.7.50/baseimages/centos-tomcat-web:app2 .
查看所有文件，上述除了build-command.sh、index.html需要修改其它不用動保持原樣
