本文主要是介绍在Ubuntu中Dcoker构建镜像，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
构建镜像
通过Dockerfile创建一个ubuntu带nginx的镜像
root@ubuntu:~# mkdir -p /dockerfile/df_test2
root@ubuntu:~# cd /dockerfile/df_test2/
root@ubuntu:/dockerfile/df_test2# vim Dockerfile
root@ubuntu:/dockerfile/df_test2# cat Dockerfile
# 设置基本的镜像，后续命令都以这个镜像为基础
FROM ubuntu
# 作者信息
MAINTAINER shangwu
# RUN命令会在上面指定的镜像里执行任何命令
RUN apt-get update
RUN apt-get install -y nginx#暴露ssh端口
EXPOSE 80
root@ubuntu:/dockerfile/df_test2# docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
ubuntu-nginx v1 8377a82bd88d 6 minutes ago 232.8 MB
ubuntu latest dc8dd8718e57 10 days ago 119.2 MB执行Dockerfile
root@ubuntu:/dockerfile/df_test2# docker build -t='ubuntu-nginx-df_test2' .
root@ubuntu:/dockerfile/df_test2# docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
ubuntu-nginx-df_test2 latest 266559c6bc7f 2 minutes ago 214.3 MB
ubuntu-nginx v1 8377a82bd88d 13 minutes ago 232.8 MB
ubuntu latest dc8dd8718e57 10 days ago 119.2 MB
root@ubuntu:/dockerfile/df_test2#
通过刚刚创建的进行启动一个容器=nginx-web3
root@ubuntu:/dockerfile/df_test2# docker run -d --name=nginx-web3 -p 80 ubuntu-nginx-df_test2 nginx -g "daemon off;"
