Steps to build specific version Redis server [Docker Edition]

Tadashi Shigeoka ·  Sat, February 9, 2019

I’ll introduce the steps to build a specific version Redis server with Docker.

Prerequisites

  • Redis: want to use version 2.8
  • OS: macOS Mojave
  • redis-cli already installed with brew install redis

Start specific version redis server with docker

Get docker image & initial startup

docker run --name redis2.8 -p 6379:6379 -d redis:2.8

Check redis startup with docker logs

docker logs redis2.8 -f

[1] 13 Feb 06:04:15.744 # Server started, Redis version 2.8.23
[1] 13 Feb 06:04:15.744 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.

[1] 13 Feb 06:04:15.744 * The server is now ready to accept connections on port 6379

Check connection to redis-server with redis-cli

Finally, check connection to the redis-server built on docker via redis-cli command and verify the version. I’ll use the redis-cli command installed on macOS with brew install redis.

$ redis-cli

Redis start/stop commands

Stop redis

docker stop redis2.8

Start redis

docker start redis2.8

That’s all from the Gemba where I occasionally want to use older versions of redis.
