Custom Dockerfile enables Docker deployment and cluster management of Redis cluster

We know that Redis cluster deployment is very cumbersome, if you start multiple Redis instances on one server, you need a single CP configuration file to the specified directory, and then modify the port and related information. I used to do this a lot. If we use Docker, we can start redis more conveniently, we just need to pass the port parameter, custom a entrypoint script in Dockerfile, the script can receive the parameters of Docker run .... But you can also use the Dockerfile env parameter to customize the port ...

This is the CentOS dockerfile configuration, version is 6.6, my side is mainly lazy, so I played a dockerfile.   Formally, it should be a need to play two dockerfile.  One is the base of the system, and the other is to install Redis through this base ...   The biggest benefit is separating the environment from the underlying environment and the business association ...  The basic environment is to install some gcc, wget, curl, lsof, iostat This common basic tool ... The business environment is, for example, Lnmp (nginx mysql php) or Mongodb ....

manage.sh This script is used to control the Redis port, the script is also simple, is to receive command line parameters, and then for Redis for sed modification ....

#!/bin/bash

CD /apps/Redis

Redis_port = $ 1

Echo $redis_port

CD /apps/Redis

When we started, we just needed docker run-d–name= "Redis-cluster" –net=host Redis_cluster 8000. Here is my process for building the Docker image image and launching the container ...

The 3.0 version is by default Jemalloc memory Manager, so remember to install his associated development package.

Make: * * * [redis-server] Error 1

Enter the Hiredis, Jemalloc, and LUA directories in the Deps directory under the Redis decompression directory to run make.

Make Hiredis Lua

Note The Jemalloc directory first executes the./configure and then the make. Once finished, jump to the SRC directory on the previous layer and continue Make;make install.

If after the installation is complete, still encounter segmentation fault core dumped problem, basically can determine your problem is jemalloc not configured to cause.
