构建Redis主从镜像
2024-08-29 10:48:58
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..tar.gz
RUN rm -rf redis-5.0..tar.gz
RUN cd redis-5.0./;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

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 .
Sending build context to Docker daemon .048kB
Step / : FROM djl/redis
---> 2125f0a93781
Step / : ENTRYPOINT [ "redis-server","--protected-mode no","--logfile /var/log/redis/redis-server.log" ]

Removing intermediate container ccb2ba2280c3
---> 9ccd42433073
Successfully built 9ccd42433073
Successfully tagged djl/redis_primary:latest
验证
# docker images

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 .
[root@localhost redis_replica]# docker build -t djl/redis_replica .
Sending build context to Docker daemon .048kB
Step / : FROM djl/redis

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