The source code and default configuration of the Building Block is available in our GitLab.
Redis consists of 5 Pods:
2 x HAProxy
3 x Redis HA Server
Add the directory
syseleven-redis-ha to your control repository. Add a
.gitlab-ci.yml to the directory with the following content:
include: - project: syseleven/building-blocks/helmfiles/redis-ha file: JobDevelopment.yaml ref: 1.0.4 - project: syseleven/building-blocks/helmfiles/redis-ha file: JobStaging.yaml ref: 1.0.4 - project: syseleven/building-blocks/helmfiles/redis-ha file: JobProduction.yaml ref: 1.0.4
Remove environments you are not using by removing their include.
For a production-grade setup, it is highly recommended to define a maxmemory limit for Redis and resource limit for the pod.
In our experience the formula
maxmemory * 125% <= limits can be used for a stable configuration.
redis: config: maxmemory: 1024MB resources: limits: memory: 1280Mi
This building block consists of multiple components. Each of the components can and must be scaled individually.
See Scaling Redis for upstream documentation.
