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 .

查看镜像
[root@docker-3 mynginx]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE

运行镜像
[root@docker-3 mynginx]# docker run -itd --name nginxv1 -p 80:80 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
FROM daocloud.io/library/centos:7
RUN yum -y install gcc gcc-c++ net-tools make wget \
&& mkdir -p /data/application/ \
&& wget https://download.redis.io/releases/redis-6.2.7.tar.gz \
&& tar zxf redis-6.2.7.tar.gz -C /data/application/
RUN cd /data/application \
&& mv redis-6.2.7/ redis \
&& cd redis/ \
&& make \
&& sed -i -e 's/bind 127.0.0.1 -::1/bind 0.0.0.0/g' ./redis.conf
EXPOSE 6379
ENTRYPOINT /data/application/redis/src/redis-server /data/application/redis/redis.conf
构建
[root@docker-2 myRedis]# docker build -t redis:v1 .

运行容器
[root@docker-2 myRedis]# vim Dockerfile
[root@docker-2 myRedis]# docker images

进入容器运行Redis
[root@docker-2 myRedis]# docker exec -it redis1 /bin/sh
sh-4.2# ls
anaconda-post.log bin data dev etc home lib lib64 media mnt opt proc redis-6.2.7.tar.gz root run sbin srv sys tmp usr var

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
