Redpanda CRD Reference

Custom resource definitions for the Redpanda resource. Use the Redpanda resource to create and manage Redpanda clusters with the Redpanda Operator.

cluster.redpanda.com/v1alpha1

Package v1alpha1 defines the v1alpha1 schema for the Redpanda API. It is part of an evolving API architecture, representing an initial stage that may be subject to change based on user feedback and further development.

Resource Types

Admin

Admin configures settings for the Admin API listeners.

Appears in:
Field Description

external object (keys:string, values:ExternalListener)

Defines settings for the external listener.

port integer

Specifies the container port number for the internal listener.

Configures TLS settings for the internal listener.

Auth

Appears in:
Field Description

sasl SASL

Configures SASL authentication in the Helm values.

Budget

Budget configures the management of disruptions affecting the Pods in the StatefulSet.

Appears in:
Field Description

maxUnavailable integer

CPU

CPU configures CPU resources for containers. See https://docs.redpanda.com/current/manage/kubernetes/manage-resources/.

Appears in:
Field Description

cores Quantity

Specifies the number of CPU cores available to the application. Redpanda makes use of a thread per core model. For details, see https://docs.redpanda.com/current/get-started/architecture/#thread-per-core-model. For this reason, Redpanda should only be given full cores. Note: You can increase cores, but decreasing cores is not currently supported. See the GitHub issue:https://github.com/redpanda-data/redpanda/issues/350. This setting is equivalent to --smp, resources.requests.cpu, and resources.limits.cpu. For production, use 4 or greater.

overprovisioned boolean

Specifies whether Redpanda assumes it has all of the provisioned CPU. This should be true unless the container has CPU affinity. Equivalent to: --idle-poll-time-us 0, --thread-affinity 0, and --poll-aio 0. If the value of full cores in resources.cpu.cores is less than 1, this setting is set to true.

Certificate

Certificate configures TLS certificates.
