- Storage recommendations: Kubernetes storage considerations for Elasticsearch workloads.
- Node configuration: Configure the
elasticsearch.ymlof your Elasticsearch nodes. - Volume claim templates: Configure storage in your Elasticsearch nodes.
- Virtual memory: Methods to accomplish Elasticsearch virtual memory system configuration requirement.
- Settings managed by ECK: List of Elasticsearch settings that you shouldn't update.
- Custom configuration files and plugins: Add extra configuration files or install plugins to your Elasticsearch nodes.
- Init containers for plugin downloads: Use Kubernetes init containers to install plugins before starting Elasticsearch.
- Advanced Elasticsearch node scheduling: Integrate standard Kubernetes scheduling options with your Elasticsearch nodes.
- Update strategy: Control how the changes are applied to the cluster.
- Pod disruption budget: Integrate Kubernetes Pod disruption budgets in your cluster.
