构建Redis主从镜像

构建Redis的基础镜像，然后基于这个基础镜像构建主Redis镜像和从Redis镜像。

1、构建Redis基础镜像

• 创建redis基础镜像目录

[root@localhost mnt]# mkdir redis_base
[root@localhost mnt]# cd redis_base/

• 创建Dockerfile

# vi Dockerfile

FROM centos:latest
MAINTAINER djl
RUN yum -y install wget
RUN yum -y groupinstall "Development Tools" "Server Platform Development"
RUN wget http://download.redis.io/releases/redis-5.0.3.tar.gz
RUN tar xf redis-5.0.3.tar.gz
RUN rm -rf redis-5.0.3.tar.gz
RUN cd redis-5.0.3/;make install
RUN sed -i "s/bind 127.0.0.1/bind 0.0.0.0/g" /redis-5.0.3/redis.conf
RUN sed -i "s/protected-mode yes/protected-mode no /g" /redis-5.0.3/redis.conf
VOLUME [ "/var/lib/redis","/var/log/redis/" ]
EXPOSE 6379

 构建Redis基础镜像

# docker build -t  djl/redis .

 查看镜像

# docker images

[root@localhost redis_base]# docker images

基于Redis基础镜像构建Redis主镜像

• 创建redis主镜像目录

[root@localhost mnt]# mkdir redis_primary
[root@localhost mnt]# cd redis_primary/
[root@localhost redis_primary]# 

• 创建Dockerfile

# vi Dockerfile

FROM test/redis
FROM djl/redis
ENTRYPOINT [ "redis-server","--protected-mode no","--logfile /var/log/redis/redis-server.log" ]

# docker build -t djl/redis_primary .

[root@localhost redis_primary]# docker build -t djl/redis_primary .

Step 2/2 : ENTRYPOINT [ "redis-server","--protected-mode no","--logfile /var/log/redis/redis-server.log" ]

基于Redis基础镜像构建Redis从镜像

• 创建redis从镜像目录

[root@localhost mnt]# mkdir redis_replica
[root@localhost mnt]# 
[root@localhost mnt]# cd redis_replica
[root@localhost redis_replica]#

• 创建Dockerfile

# vi Dockerfile

FROM test/redis
FROM djl/redis
ENTRYPOINT [ "redis-server","--protected-mode no","--logfile /var/log/redis/redis-replica.log","--slaveof redis_primary 6379" ]

# docker build -t djl/redis_replica .
