1.准备镜像文件tomcat 压缩包，jdk压缩包
2.如果dockerfile的名字就是Dockerfile的话，就不需要-f写名字了。
FROM centos MAINTAINER test<12345.qq.com> COPY readme.txt /usr/local/readme.txt #拷贝本地的一个文件到镜像里 ADD jdk-8u110-linux-x64.tar.gz /usr/local/ #添加一个压缩包，docker会自动解压 ADD apache-tomcat-9.0.22.tar.gz /usr/local/ RUN yum -y install vim ENV MYPATH /usr/local WORKDIR $MYPATH ENV JAVA_HOME /usr/local/jdk1.8.0_11 ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar ENV CATALINA_HOME /usr/local/apache-tomcat-9.0.22 ENV CATALINA_BASH /usr/local/apache-tomcat-9.0.22 ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/lib:$CATALINA_HOME/bin EXPOSE 8080 #暴露端口8080 CMD /usr/local/apache-tomcat-9.0.22/bin/startup.sh && tail -F /url/local/apache-tomcat-9.0.22/bin/logs/catalina.out
2.docker build -t mytomcat .
直接build
制作好自己的镜像后
1.到docker hub上注册自己的账号
2.确定这个账号可以登录
3.docker login --help
4.登录完毕后提交镜像，docker push
[root@localhost dockerfile]# docker login -u johnmand Password: WARNING! Your password will be stored unencrypted in /root/.docker/config.json. Configure a credential helper to remove this warning. See https://docs.docker.com/engine/reference/commandline/login/#credentials-store Login Succeeded
但是被拒绝了，修改一个名字和tag,push成功了。
