Data Services Reference Stack(DSRS) - Redis*

DSRS Redis is packaged as a Docker container based on CentOS 8 and a set of scripts to build components including:

Source code

The latest source code and documentation related to build and deploy the image can be found here:

DSRS Redis Stack

This project is a Redis stack enabled for multinode Kubernetes environment using PMem in fsdax mode for storage.

The source code used for this application can be found in the Redis PMEM repository

You can lookup for image names executing the command docker images. This will list all your available images, if you don’t have a DSRS Redis image, you can build one or download one.

Build DSRS Redis image

To build an image by yourself, install the docker dependencies and run the following command:

docker build --force-rm --no-cache -f Dockerfile -t ${DOCKER_IMAGE} .

Run DSRS Redis as a standalone container

Prior to start the application, you will need to have the PMem in fsdax mode with a file system and mounted in /mnt/dax0. To know how to configure, read the documentation of DSRS

To start the application

docker run --mount type=bind,source=/mnt/dax0,target=/mnt/pmem0 -i -d --name pmem-redis ${DOCKER_IMAGE} --nvm-maxcapacity 200 --nvm-dir /mnt/pmem0 --nvm-threshold 64 --protected-mode no

Deploy DSRS Redis cluster on Kubernetes

Kubernetes setup

As first step you need a Kubernetes cluster running on a Linux distribution supporting Persistent Memory. After setting up Kubernetes, you will need to enable it to support DCPMM suing the pmem-csi driver. To install the driver follow the instructions in the repo file.

Redis operator install

The source code of the redis operator can be found in this repository.

To install the operator, go to you kubernetes control plane and execute the following command:

kubectl create -f

Redis operator usage

After installing the operator you are ready to deploy redisfailover instances using a yaml file, there is an example for persistent memory here. You can download it and change the source of the image to wherever DSRS Redis image is located. We have created our own yaml based on this example, you can find it in this repo with the name: test/redis-failover.yml

In the test/redis-failover.yml there is a placeholder for the image name, substitute the word PMEM_REDIS_IMAGE with the name of the DSRS redis image.

To start a redisfailover instance in Kubernetes using our yaml, move the file to the kubernetes server, then run:

kubectl create -f redis-failover.yml

Known issues

There is an issue of the sentinels not having enough memory to create the InitContainer. The issue has been reported here. The current workaround is to build the image increasing the limits for the InitContainer memory to 32Mb

Note If you already have a redis-operator, you will need to delete it before installing a new one.
