To ensure high availability of Redis, we recommend using Redis in Cluster mode with at least 3 nodes (must be an odd number of nodes) and using the master-slave model, which means that the number of servers increases to 6. And we need one more node for HAProxy. This container can be used to create a data-sharded, high-availability Redis cluster. There are 3 master nodes and 3 replica nodes. Redis is an open source in-memory remote database that supports many different data structures: strings, hashes, lists, sets, sorted sets, and more. Enter the host name of your Redis server.

To have high availability you need more than one node, and of course you need load balancing. Sentinel requires a number of instances, and works as a group of decision-makers, before deciding which node is up or down and when the failover should be … Redis is an exceptionally fast remote in-memory database solution.

You can see that the UI indicated that you have 4 shards with replication*. We know that there are two categories of Redis clusters: one is Redis Sentinel, a high-availability cluster with only one master database at the same time and data on various instances is consistent; the other is Redis Cluster, a distributed cluster with multiple master databases at the same time and data is sliced and deployed on various master instances. 12.3 — Click on “Delete”. If the Redis pod comes to a stop, or if the OpenShift Container Platform stops it, a new pod is automatically created. It can be used as a database, a cache, and a message broker. Posted on Dec 29, 2019 . In this configuration, every node should have at least 2 cores and 2 GB of RAM. It creates a three node Redis cluster with redis-sentinel and haproxy.

It can provide node monitoring, notification, automatic fault recovery and client configuration discovery services. Install Docker and Docker Compose in testing environment. Memorystore for Redis provides high availability by replicating a primary Redis node to a replica node. To see the failover in action, you need to start the platform and deploy the application: [bash] git clone https://github.com/mvanholsteijn/coreos-container-platform-as-a-service.git cd coreos-container-platform-as-a-service/vagrant vagrant up ./is_platform_ready.sh [/bash] This will start 3 NFS servers and our 3 node CoreOS cluster.

The redis instances listen on the host node ports: 6379-6384. It is a monitoring and management tool for Redis cluster. It supports data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, HyperLogLogs, geospatial indexes with radius queries, and streams. While considering high performance, high availability is also an important consideration. Prerequisite.
