Dockerfile构建Tomcat基础镜像
作者：互联网
1、安装docker并修改阿里云仓库地址，并重启
yum -y install docker
service enabled docker
vim /etc/docker/daemon.json
{
"registry-mirrors": ["https://mj9kvemk.mirror.aliyuncs.com"]
}
service restart docker
2、修改/etc/yum.repos.d/CentOS-Base.repo不校验签名
sed -i 's/gpgcheck=1/gpgcheck=0/g' /etc/yum.repos.d/*
yum makecache fast
yum repolist
3、编写Dockerfile
cd /home
[root@VM-0-17-centos home]# cat Dockerfile
FROM centos:7
MAINTAINER wangmiao
ENV VERSION=8.5.39
ENV JAVA_HOME /usr/local/jdk
RUN yum install wget -y
RUN wget http://archive.apache.org/dist/tomcat/tomcat-8/v${VERSION}/bin/apache-tomcat-${VERSION}.tar.gz && \
tar zxf apache-tomcat-${VERSION}.tar.gz && \
mv apache-tomcat-${VERSION} /usr/local/tomcat && \
rm -rf apache-tomcat-${VERSION}.tar.gz /usr/local/tomcat/webapps/*
EXPOSE 8080
CMD ["catalina.sh", "run"]
docker build -t tomcat-8.5.39:v1 .
4、构建镜像
[root@VM-0-17-centos home]# docker build -t tomcat-8.5.39:v1 .
