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:7RUN buildDeps='readline-devel pcre-devel openssl-devel gcc telnet wget curl make' && \yum -y install $buildDeps && \yum clean allRUN wget https://nginx.org/download/nginx-1.24.0.tar.gz && \tar zfx nginx-1.24.0.tar.gz -C /optRUN cd /opt/nginx-1.24.0 && \mkdir /usr/local/nginx && \./configure --prefix=/usr/local/nginx \--with-http_ssl_module \--with-http_stub_status_module && \make && make install && \rm -rf /usr/local/nginx/html/* && \echo "nihao" > /usr/local/nginx/html/index.html && \cd / && rm -rf /opt/nginx-1.24.0 && \ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtimeENV PATH /usr/local/nginx/sbin:$PATHWORKDIR /usr/local/nginxEXPOSE 80CMD ["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
FROM daocloud.io/library/centos:7RUN 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.confEXPOSE 6379ENTRYPOINT /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 imagesREPOSITORY TAG IMAGE ID CREATED SIZEredisv115c74862351b 6 days ago672MB[root@docker-2 myRedis]# docker run -itd --name redis1 -p 6379:6379 redis:v1dc76e2462b7ae0a63ed673bc2f247302a1bec336bc6320a5f67c5cd2051ebf41[root@docker-2 myRedis]# docker psCONTAINER ID IMAGECOMMAND CREATED STATUS PORTS NAMESdc76e2462b7a redis:v1 "/bin/sh -c '/data/a…" 4 seconds ago Up 3 seconds 0.0.0.0:6379->6379/tcp, :::6379->6379/tcp redis1

进入容器运行Redis

[root@docker-2 myRedis]# docker exec -it redis1 /bin/shsh-4.2# lsanaconda-post.logbindatadevetchomeliblib64mediamntoptprocredis-6.2.7.tar.gzrootrunsbinsrvsystmpusrvarsh-4.2# cd data/application/redis/sh-4.2# ./src/redis-cli 127.0.0.1:6379> pingPONG127.0.0.1:6379>

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
