创建数据存放目录

[root@localhost compose_lnmt]# mkdir -p /var/www/html/

编写tomcat的dockerfile

[root@localhost compose_lnmt]# mkdir -p tomcat

[root@localhost compose_lnmt]# cd tomcat/

下载tomcat的dockers文件

https://mirrors.bfsu.edu.cn/apache/tomcat/tomcat-8/v8.5.59/bin/apache-tomcat-8.5.59.tar.gz

如果这一步做了下面就不用了

这里上一步做了就可以跳过

在tomcat目录下放一个apache包

[root@localhost tomcat]# ll
总用量 9600
-rw-r--r--. 1 root root 9690027 7月 17 2020 apache-tomcat-8.5.40.tar.gz

[root@localhost tomcat]# vim Dockerfile

[root@localhost tomcat]# cat Dockerfile 
# this docker file

# author: shichao# email: shichao@scajy.cn
FROM centos:7
MAINTAINER  shichao@scajy.cn
ENV VERSION=8.5.40                  看这里根据版本号写
RUN yum install -y gcc gcc-c++ make gd-devel libxml2-devel libcurl-devel libjpeg-devel libpng-devel openssl-devel net-tools wget curl unzip iproute java-1.8.0-openjdk && yum clean all  && rm -rf /var/cache/yum/* 
ADD apache-tomcat-${VERSION}.tar.gz /usr/local/
RUN mv /usr/local/apache-tomcat-${VERSION}   /usr/local/tomcat &&\sed -i '1a JAVA_OPTS="-Djava.security.egd=file:/dev/./urandom"' /usr/local/tomcat/bin/catalina.sh && \ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
ENV PATH /usr/local/tomcat/bin:$PATH
WORKDIR /usr/local/tomcatEXPOSE 8080CMD ["catalina.sh", "run"]

拷贝tomcat数据到容器目录下

mkdir -p /var/www/tomcat

cp -a /usr/local/tomcat/webapps/* /var/www/tomcat/

如果没有

apache-tomcat-8.5.40.tar.gz 把一个apache包解压把文件放到/var/www/tomcat/

[root@localhost tomcat]# ll /var/www/tomcat/
总用量 8
drwxr-x---. 14 root root 4096 8月   4 16:52 docs

切换目录

编写docker compose配置文件

[root@localhost tomcat]# cd ..
