Docker通过Dockerfile创建Redis、Nginx--详细过程

创建Nginx镜像

我们先创建一个目录，在目录里创建Dockerfile

[root@docker-3 ~]# mkdir mynginx
[root@docker-3 ~]# cd mynginx
[root@docker-3 ~]# vim Dockerfile

Dockerfile的内容

FROM daocloud.io/library/centos:7
RUN buildDeps='readline-devel pcre-devel openssl-devel gcc telnet wget curl make' && \yum -y install $buildDeps && \yum clean all
RUN wget https://nginx.org/download/nginx-1.24.0.tar.gz && \tar zfx nginx-1.24.0.tar.gz -C /opt
RUN cd /opt/nginx-1.24.0 && \mkdir /usr/local/nginx && \./configure --prefix=/usr/local/nginx \--with-http_ssl_module \--with-http_stub_status_module && \make && make install && \rm -rf /usr/local/nginx/html/* && \echo "nihao" > /usr/local/nginx/html/index.html && \cd / && rm -rf /opt/nginx-1.24.0 && \ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
ENV PATH /usr/local/nginx/sbin:$PATH
WORKDIR /usr/local/nginx
EXPOSE 80
CMD ["nginx","-g","daemon off;"]

开始构建，别忘了最后的  . 

[root@docker-3 mynginx]# docker build -t nginx:v1 .

创建Redis镜像

创建目录，在目录里创建Dockerfile

[root@docker-2 ~]# mkdir myRedis
[root@docker-2 ~]# cd myRdis
[root@docker-2 ~]# vim Dockerfile

构建

[root@docker-2 myRedis]# docker build -t redis:v1 .

我这里只修改了配置文件的bind，  如果有需要其他使用sed更改即可
