temporal-operator

The Kubernetes Operator to deploy and manage Temporal clusters.

Using this operator, deploying a Temporal Cluster on Kubernetes is as easy as deploying the following manifest:

apiVersion: temporal.io/v1beta1
kind: TemporalCluster
metadata:
  name: prod
  namespace: demo
spec:
  version: 1.23.0
  numHistoryShards: 1
  persistence:
    defaultStore:
      sql:
        user: temporal
        pluginName: postgres
        databaseName: temporal
        connectAddr: postgres.demo.svc.cluster.local:5432
        connectProtocol: tcp
      passwordSecretRef:
        name: postgres-password
        key: PASSWORD
    visibilityStore:
      sql:
        user: temporal
        pluginName: postgres
        databaseName: temporal_visibility
        connectAddr: postgres.demo.svc.cluster.local:5432
        connectProtocol: tcp
      passwordSecretRef:
        name: postgres-password
        key: PASSWORD

Documentation

The documentation is available at: https://temporal-operator.pages.dev/.

Quick start

To start using the Operator and deploy you first cluster in a matter of minutes, follow the documentation's getting started guide.

Examples

Somes examples are available to help you get started:

• Temporal Cluster with PostgreSQL
• Temporal Cluster with MySQL
• Temporal Cluster with Cassandra
• Temporal Cluster with PostgreSQL & advanced visibility using ElasticSearch
• Temporal Cluster with mTLS using cert-manager & PostgreSQL as datastore
• Temporal Cluster with mTLS using istio & PostgreSQL as datastore
• Temporal Cluster with mTLS using linkerd & PostgreSQL as datastore

Compatibility matrix

The following table shows operator compatibility with Temporal and Kubernetes. Please note this table only reports end-to-end tests suite coverage, others versions may work.
