While Redis Helm Chart will deploy a master-slave cluster using Redis Sentinel, the Redis Cluster Helm Chart will deploy a Redis Cluster topology with sharding. What changes were introduced in this major version? You can use this file instead of the default one.

If you want to keep your data, you will need to perform a backup and then a restore the data in this new version. able to connect to Redis. “What about BookSleeve?”) please see here. (redis slave pod), Additional labels for redis slave StatefulSet, Additional annotations for redis slave StatefulSet, Additional Environment Variables passed to the pod of the slave's stateful set set, Additional Environment Variables ConfigMappassed to the pod of the slave's stateful set set, Additional Environment Variables Secret passed to the slave's stateful set, Additional annotations for Redis slave pod, Redis slave CPU/Memory resource requests/limits, Toleration labels for Redis slave pod assignment, Timeout for querying the redis sentinel service for the active sentinel list, Timeout for detecting a Redis node is down, Timeout for performing a election failover, Additional Redis configuration for the sentinel nodes (this value is evaluated as a template), Enable static IDs for sentinel replicas (If disabled IDs will be randomly generated on startup), Kubernetes Service nodePort (redis sentinel), Additional labels for redis sentinel service, Kubernetes Service port for Redis read only operations, Kubernetes Service port for Redis sentinel, Kubernetes Service node port for Redis read only operations, Kubernetes Service node port for Redis sentinel, LoadBalancerIP if Redis sentinel service type is, Turn on and off liveness probe (redis sentinel pod), Delay before liveness probe is initiated (redis sentinel pod), How often to perform the probe (redis sentinel container), When the probe times out (redis sentinel container), Minimum consecutive successes for the probe to be considered successful after having failed (redis sentinel container), Turn on and off sentinel.readiness probe (redis sentinel pod), Delay before sentinel.readiness probe is initiated (redis sentinel pod), How often to perform the probe (redis sentinel pod), Minimum consecutive failures for the probe to be considered failed after having succeeded. Finally, it fixes https://github.com/helm/charts/issues/7803 by removing mutable labels in spec.VolumeClaimTemplate.metadata.labels so that it is upgradable. It contains all the supporting project files necessary to work through the book from start to finish. The slaves will be read-replicas of the master. To use a password file for Redis you need to create a secret containing the password. Work fast with our official CLI. For example. Additional options are simply appended (comma-delimited). Redis Slave service: Points to the slaves, where only read operations are allowed. If nothing happens, download Xcode and try again. For example, in 6.0.0 slaves.readinessProbe.periodSeconds, if empty, would be set to master.readinessProbe.periodSeconds. Mastering Redis. The metrics exporter has been changed from a separate deployment to a sidecar container, due to the latest changes in the Redis exporter code. added, causing any subsequent upgrade to fail. a networking plugin that implements the Kubernetes NetworkPolicy spec, See https://github.com/helm/charts/issues/7726. The default image in this release may be switched out for any image containing the redis-server Another important change is that no values are inherited from master to slaves. This label will be displayed in the output Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. Redis provides data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes, and streams.
