dockerfile部署wordpress

1.将容器直接提交成镜像

[root@localhost ~]# docker commit 8ecc7f6b9c12 nginx:1.1
sha256:9a2bb94ba6d8d952527df616febf3fbc8f842b3b9e28b7011b50c743cd7b233b
[root@localhost ~]# docker images
REPOSITORY   TAG           IMAGE ID       CREATED         SIZE
nginx        1.1           9a2bb94ba6d8   7 seconds ago   236MB
rockylinux   9.3           583a894199be   5 hours ago     181MB

将容器的文件挂载到宿主机目录下，容器删除掉，它的文件也会存在

[root@lvs-server ~]# docker run -itd  -e MYSQL_ROOT_PASSWORD=QianFeng@123 -v /opt/data:/var/lib/mysql  mysql:8.0.38-oraclelinux9
fa63565b79532d028a09fc731496a02a0e442b2367b23c932ee6286e5e39f68d

前面的路径是宿主机的，后面的是容器的

Dockerfile内容：

#写在第一行，定义使用的夫镜像是哪一个

FROM docker.io/library/rockylinux:9.3

#指定作者描述信息

MAINTAINER dagou

# RUN yum install -y epel-release

# RUN yum install -y nginx

#指定变量

# ARG VERSION=1.0

#ADD souce dest

#拷贝文件到镜像内

#1.支持网络资源拷贝，后面要加域名，如：http://www.example.com/file.tar.gz

#2.如果拷贝的是tar包，会自动的将tar包内的东西一同拷贝到镜像内，会自动解压

#1和2不可以同时使用

#给镜像打标签

LABEL MAINTAINER="dagou youxiang:[e-mail] build time='7-20'"

#构建镜像执行的命令

RUN yum -y install wget

#拷贝文件到镜像内

COPY ./nginx.conf /etc/nginx/nginx.conf

#暴露端口

EXPOSE 80 443

#如果是官网的nginx,首先创建一个以.repo结尾的文件，把官网的nginx源放进去

#COPY ./nginx.repo /etc/yum.repos.d/

#声明一个数据目录或者是配置目录，供容器使用(映射)
