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 IMAGE CREATED CREATED BY SIZE COMMENT 53f3fd8007f7 12 months ago /bin/sh -c #(nop) CMD ["nginx" "-g" "daemon… 0B #cmd命令 <missing> 12 months ago /bin/sh -c #(nop) STOPSIGNAL SIGTERM 0B <missing> 12 months ago /bin/sh -c #(nop) EXPOSE 80 0B #EXPOSE 暴露端口 <missing> 12 months ago /bin/sh -c ln -sf /dev/stdout /var/log/nginx… 22B <missing> 12 months ago /bin/sh -c set -x && apt-get update && apt… 54.1MB <missing> 12 months ago /bin/sh -c #(nop) ENV NJS_VERSION=1.15.12.0… 0B #ENV 环境变量 <missing> 12 months ago /bin/sh -c #(nop) ENV NGINX_VERSION=1.15.12… 0B <missing> 12 months ago /bin/sh -c #(nop) LABEL maintainer=NGINX Do… 0B <missing> 12 months ago /bin/sh -c #(nop) CMD ["bash"] 0B #cmd命令 <missing> 12 months ago /bin/sh -c #(nop) ADD file:fcb9328ea4c115670… 55.3MB [ ~]#
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 .

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
