Dockerfile、Harbor镜像仓库

一、Dockerfile

1.Dockerfile格式
2.Dockerfile指令
3.Build镜像
4.构建Nginx，PHP，Tomcat基础镜像
5.快速搭建LNMP网站平台

1、Dockerfile格式

2、Dockerfile指令

[ ~]# docker history nginx:1.15

[ ~]#

3、Build镜像

docker  build  　　-t  新构建镜像名称　　-f 指定Dockerfile文件位置      其他配置文件路径
Usage: docker build [OPTIONS] PATH | URL | -[flags]Options:
-t, --tag list # 镜像名称
-f, --file string # 指定Dockerfile文件位置
# docker build .
# docker build -t shykes/myapp .
# docker build -t shykes/myapp -f /path/Dockerfile /path
# docker build -t shykes/myapp http://www.example.com/Dockerfile

[ ~]# vim dockerfile
FROM centos:7
MAINTAINER mxxl
RUN yum install httpd -y
COPY index.html /var/www/html
ENV HTTP_V=2.0
EXPOSE 80
WORKDIR /tmp
CMD ["httpd","-D","FOREGROUND"]
[ ~]# 
[ ~]# vim index.html
haha
[ ~]# docker build -t http:v2 .
REPOSITORY                       TAG                 IMAGE ID            CREATED             SIZE

[ ~]# docker inspect b3217f3dec25 |grep IPAddress
            "SecondaryIPAddresses": null,
            "IPAddress": "172.17.0.2",
                    "IPAddress": "172.17.0.2",
[ ~]# 
[ ~]# curl 172.17.0.2

4、构建业务基础镜像
•构建Nginx基础镜像
•构建PHP基础镜像
•构建Tomcat基础镜像


快速部署LNMP网站平台
1、自定义网络
docker network create lnmp
2、创建Mysql容器
docker run -d \
--name lnmp_mysql \
--net lnmp \
--mount src=mysql-vol,dst=/var/lib/mysql \
-e MYSQL_ROOT_PASSWORD=123456 -e MYSQL_DATABASE=wordpress mysql:5.7 --character-set-server=utf8
3、创建PHP容器
docker run -d --name lnmp_php --net lnmp --mount src=wwwroot,dst=/wwwroot php:v1
4、创建Nginx容器
docker run -d --name lnmp_nginx --net lnmp -p 88:80 \
--mount type=bind,src=$(pwd)/nginx.conf,dst=/usr/local/nginx/conf/nginx.conf --mount src=wwwroot,dst=/wwwroot nginx:v1
5、以wordpress博客为例
https://cn.wordpress.org/wordpress-4.9.4-zh_CN.tar.gz


1、自定义网络
[ ~]# docker network create lnmp
9cdfea34f9cd55af4fca8e2bf3be6ca92cab1ca2632a5ec1178173420d52ccaf
[ ~]#
[ ~]# ls
anaconda-ks.cfg  dockerfile  wordpress-4.9.4-zh_CN.tar.gz
[ ~]# cd dockerfile/
[ dockerfile]# ls
Dockerfile-nginx  Dockerfile-php  Dockerfile-tomcat  nginx.conf  php-fpm.conf  php.ini
2、创建Mysql容器
[ dockerfile]#
docker run -d \
--name lnmp_mysql \
--net lnmp \
--mount src=mysql-vol,dst=/var/lib/mysql \
-e MYSQL_ROOT_PASSWORD=123456 -e MYSQL_DATABASE=wordpress mysql:5.7 --character-set-server=utf8
3、创建PHP容器
[ dockerfile]# cat Dockerfile-php #php镜像构造的dockerfile
FROM centos:7
