Python 2 Compatibility Note. You signed in with another tab or window. That means that we moved from Deployment to StatefulSets. You'll want to use this dashboard now. This should not affect upgrades from previous versions of the chart, as the deployments did not contain any persistence at all. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets, sorted sets, bitmaps and hyperloglogs. Use Git or checkout with SVN using the web URL. For example, image.tag=X.Y.Z. The main features of each chart are the following: To install the chart with the release name my-release: The command deploys Redis on the Kubernetes cluster in the default configuration. The following parameters should be configured to properly enable the TLS support in the chart: First, create the secret with the cetificates files: The chart optionally can start a metrics exporter for prometheus. To perform a backup you will need to connect to one of the nodes and execute: Then you will need to get the created dump file form the redis node: To restore in a new cluster, you will need to change a parameter in the redis.conf file and then upload the dump.rdb to the volume. Type-safe Redis client for Golang. To modify the Redis version used in this chart you can specify a valid image tag using the image.tag parameter. As an alternative, one of the following could be done: Recommended: Create a clone of the Redis Master PVC (for example, using projects like this one). This label will be displayed in the output Another important change is that no values are inherited from master to slaves. The metrics endpoint (port 9121) is exposed in the service. PhpRedis. Specifies annotations to add to ServiceAccount. The metrics exporter has been changed from a separate deployment to a sidecar container, due to the latest changes in the Redis exporter code. Learn more. The simplestconfiguration example is just the host name: This will connect to a single server on the local machine using the default redis port (6379). Additional options are simply appended (comma-delimited). Use slaveof to make a Redis instance a copy of # another Redis server. Find more information in this section. Considerations when upgrading to this version, When deployed with sentinel enabled, only a group of nodes is deployed and the master/slave role is handled in the group. It is strongly recommended to use immutable tags in a production environment. In order to query the current master (no redis master service is exposed), you need to query first the Sentinel cluster. You can use this file instead of the default one. The default image in this release may be switched out for any image containing the redis-server It is the logical successor to BookSleeve,and is the client developed-by (and used-by) Stack Exchange for busy sites like Stack Overflow.

This version causes a change in the Redis Master StatefulSet definition, so the command helm upgrade would not work out of the box. This chart includes a values-production.yaml file where you can find some parameters oriented to production configuration in comparison to the regular values.yaml. To use a password file for Redis you need to create a secret containing the password. Now that the PVC were created, stop it and copy the, Using a version of redis-sentinel prior to. Create a dir with access granted # only to Redis user and configure Redis to create the swap file there. The command, Additional Redis configuration for the slave nodes (this value is evaluated as a template), Array of Redis commands to disable (slave), Redis slave additional command line flags, Turn on and off liveness probe (redis slave pod), Delay before liveness probe is initiated (redis slave pod), How often to perform the probe (redis slave pod), When the probe times out (redis slave pod), Minimum consecutive successes for the probe to be considered successful after having failed (redis slave pod), Turn on and off slave.readiness probe (redis slave pod), Delay before slave.readiness probe is initiated (redis slave pod), Minimum consecutive failures for the probe to be considered failed after having succeeded. For example, in 6.0.0 slaves.readinessProbe.periodSeconds, if empty, would be set to master.readinessProbe.periodSeconds. For write operations, it's necessary to access the Redis Sentinel cluster and query the current master using the command below (using redis-cli or similar: This command will return the address of the current master, which can be accessed from inside the cluster. It also fixes https://github.com/helm/charts/issues/7726 where a deployment extensions/v1beta1 can not be upgraded if spec.selector is not explicitly set. 774. redis-master.conf.
