1,Dockerfile的编写

在centos中创建一个目录:/mydata/data/dockertest/,新建Dockerfile文件
vim Dockerfile

# Verison 0.6:

# 基础镜像
FROM chenbb/fofeasy:0.6

# 维护者信息
MAINTAINER cbbing@163.com

# 镜像操作命令
RUN rm -rf /opt/tomcat/webapps/fofeasy
RUN rm -rf /opt/tomcat/webapps/fofeasy.war

ADD fofeasy.war /opt/tomcat/webapps/fofeasy.war

# 容器启动命令
#CMD ["/opt/tomcat/bin/catalina.sh", "run"]

编写完成后:wq保存。

2,构建

基于Dockerfile构建镜像,在Dockerfile文件所在目录下执行

[root@VM_200_249_centos dockertest]# docker build -t chenbb/fofeasy:0.7 .

[root@VM_200_249_centos dockertest]#

注:

chenbb/fofeasy:0.7为新镜像的名字
fofeasy.war文件放到同一目录

[root@VM_200_249_centos dockertest]# ll -lh
总用量 63M
-rw-r--r-- 1 root root 322 3月   3 17:00 Dockerfile
-rw-r--r-- 1 root root 63M 3月   3 16:46 fofeasy.war

3,启动

docker run -d -p 58080:8080 --name javaweb chenbb/javaweb:0.7 /root/run.sh
