Dockerfile构建LNMP镜像教程

通过Dockerfile来进行Docker的镜像制作,本文章只演示镜像打包

FROM 使用的镜像，如果没有则会拉取 MAINTAINER 作者 COPY 拷贝文件至镜像指定位置 RUN 镜像制作时执行的命令 CMD 镜像制作启动时执行的命令 准备基础环境

拉取centos7镜像:

[root@master docker]# docker pull centos:7

pull下载过慢可下载tar包并进行导入

[root@master ~]# wget https://file.api.ym68.cc/docker/images/centos_7.tar [root@master ~]# docker load -i centos_7.tar 构建环境 MySQL

编辑Dockerfile文件内容

[root@master mysql]# vim Dockerfile FROM docker.io/centos:7MAINTAINER <admin@ym68.cc> COPY mysql_57//usr/local/mysql_57/ RUN yum -y install openssl-libs

开始build构建Mysql镜像

[root@master mysql]# docker build -t mysql:v5.7.29 ./ Sending build context to Docker daemon 1.694 GB Step 1/4 : FROM docker.io/centos:7 —> b5b4d78bc90c Step 2/4 : MAINTAINER <admin@ym68.cc> —>Using cache —> 06fa3abfc1cf Step 3/4 : COPY mysql_57/ /usr/local/mysql_57/ —> Using cache —> 7e7a1a1a78c4Step 4/4 : RUN yum -y install openssl-libs —> Using cache —> 7d9d2bac5b99Successfully built 7d9d2bac5b99Nginx

编辑Dockerfile文件内容

[root@master nginx]# vim Dockerfile FROM docker.io/centos:7MAINTAINER <admin@ym68.cc> COPY nginx//usr/local/nginx/RUN yum -y install gd-devel pcre-devel openssl openssl-devel

开始build构建Nginx镜像

[root@master nginx]# docker build -t nginx:v1.17.10 ./ PHP

编辑Dockerfile文件内容

[root@master php]# vim Dockerfile FROM docker.io/centos:7 MAINTAINER <admin@ym68.cc> COPY php72/ /usr/local/php72/ RUN yum -y install libpng autoconf libxslt libjpeg-turbo freetype

开始build构建PHP镜像

[root@master php]# docker build -t php:v7.2 ./ 查看结果

查看images列表

[root@master nginx]# docker imagesREPOSITORY TAG IMAGE ID CREATED SIZE nginx v1.18 20dabe80ad0c 2 minutes ago 306 MB php v7.2 1d279f0043d9 31 minutes ago 520 MB mysql v5.7.29 7d9d2bac5b99 49 minutes ago 1.97 GB centos 7 b5b4d78bc90c 4weeks ago203 MB docker.io/centos 7 b5b4d78bc90c 4 weeks ago 203 MB 通过docker-compose启动容器

配置docker-compose

[root@master ~]# wget -O /usr/local/bin/docker-compose https://file.api.ym68.cc/docker/sbin/docker-compose [root@master ~]# chmod +x /usr/local/bin/docker-compose

编辑启动文件并进行配置，根据实际需要进行配置

由于配置是根据自己实际需要进行修改的，此教程仅供参考。如果根据教程来你会缺少配置文件及启动脚本。 [root@master conf]# vim WebSite_All.yaml version: 2.3services: nginx: image: nginx:v1.18 container_name: nginx cpu_count: 1 cpu_percent: 50 cpus: 0.5 cpu_shares: 73 cpuset: 0,1 mem_limit: 512m memswap_limit: 1024m mem_reservation: 125m shm_size: 64M hostname: nginx-servercommand: /bin/bash /usr/local/bin/nginxd start ports: – “80:80” – “443:443” volumes: – /data/nginx/sbin/nginxd.sh:/usr/local/bin/nginxd – /data/nginx/wwwroot:/wwwroot/ – /data/nginx/conf/nginx.conf:/usr/local/nginx/conf/nginx.conf – /data/nginx/ssl/:/usr/local/nginx/ssl/ – /data/nginx/vhost/:/usr/local/nginx/vhost/ – /dev/shm/php-fpm.sock:/dev/shm/php-fpm.sock – /etc/hosts:/etc/hosts networks: website: ipv4_address: 10.173.68.88 mysql_db: container_name: mysql_57 image: mysql:v5.7.29 cpu_count: 1 cpu_percent: 50 cpus: 1 cpu_shares: 73 cpuset: 0,1 mem_limit: 1024m memswap_limit: 2049m mem_reservation: 248m shm_size: 64Mcommand: /bin/bash /usr/local/mysql_57/sbin/mysqld.sh hostname: mysql-server volumes: – /data/mysql/data:/usr/local/mysql_57/data – /data/mysql/conf:/usr/local/mysql_57/conf – /data/mysql/logs:/usr/local/mysql_57/logs – /data/mysql/sbin:/usr/local/mysql_57/sbin – /data/mysql/backup:/usr/local/mysql_57/backup networks: website: ipv4_address: 10.173.68.77 php_fpm: container_name: php image: php:v7.2 cpu_count: 1 cpu_percent: 50 cpus: 1 cpu_shares: 73 cpuset: 0,1 mem_limit: 1024m memswap_limit: 1621m mem_reservation: 248m shm_size: 64M hostname: php-servercommand: /bin/bash /usr/local/bin/phpd start volumes: – /data/php/sbin/phpd:/usr/local/bin/phpd – /data/php/php.ini:/usr/local/php72/php.ini – /data/php/ext/:/usr/local/php72/lib/php/extensions/no-debug-non-zts-20170718/ – /data/php/etc/:/usr/local/php72/etc/ – /data/nginx/wwwroot:/wwwroot/ – /dev/shm/php-fpm.sock:/dev/shm/php-fpm.sock – /etc/hosts:/etc/hosts networks: website: ipv4_address: 10.173.68.99 networks: website: ipam: config: – subnet: 10.173.68.0/24 gateway: 10.173.68.1

启动容器

[root@master conf]# docker-compose -f /data/docker/conf/WebSite_All.yaml up -dCreating network“conf_website” with the default driver Creating nginx … done Creating php … doneCreating mysql_57 …done 上传镜像至dockerhub

登陆docker

[root@master conf]# docker loginLogin with your Docker ID to pushand pull images from Docker Hub. If you dont have a Docker ID, head over to https://hub.docker.com to create one Username: ymcc Password: Login Succeeded

更改tag为用户名开头

[root@master conf]# docker tag mysql:v5.7.29 ymcc/mysql:v5.7.29 [root@master conf]# docker tag php:v7.2 ymcc/php:v7.2 [root@master conf]# docker tag nginx:v1.18 ymcc/nginx:v1.18

上传镜像

[root@master conf]# docker push ymcc/mysql:v5.7.29 [root@master conf]# docker push ymcc/php:v7.2 [root@master conf]# docker push ymcc/nginx:v1.18
