About Customizations for a TimesTen Operator Deployment

The operator.yaml YAML file defines the Deployment to run the TimesTen Operator in a namespace-scoped environment and the cluster_operator.yaml YAML file defines the Deployment to run the TimesTen Operator in a cluster-scoped environment. These files provide customizations that you can make for your specific environment. The customizations that you can make are the same for namespace-scoped and cluster-scoped ennvironments.

The ttoperator and ttclusteroperator Helm charts define the TimesTen Operator deployments using Helm. If you are using Helm, see Use Helm in Your TimesTen Kubernetes Operator Environment.

The following information is specific to YAML manifest files:

To customize the TimesTen Operator, modify either the operator.yaml or cluster_operator.yaml file (modify operator.yaml for namespace-scoped environments or cluster_operator.yaml for cluster-scoped environments). The modifications are as follows:

• image: Container image to run.

• imagePullSecrets: Image pull secret that contains the credentials to access the image registry for the image.

• replicas: Number of TimesTen Operator Pods to run.

• affinity: Section that allows you to define whether the TimesTen Operator runs on amd64 or arm64 Nodes. These Node settings are specific to running in a multi-architecture Kubernetes environment. See About Deploying in a Multi-Architecture Kubernetes Cluster.

• Environment variables for the TimesTen Operator. Even though we recommend that you do not change the default settings, these are the environment variables that are customizable if you so choose:

  • CREATE_SERVICEMONITOR: See Expose Metrics from the TimesTen Kubernetes Operator.

  • EXPOSE_METRICS: See Expose Metrics from the TimesTen Kubernetes Operator.

  • EXPOSE_PROBES: See About Readiness and Liveness Probes.

  • METRICS_SCHEME: See Expose Metrics from the TimesTen Kubernetes Operator.

  • TT_MAX_RECONCILES: See TimesTen Kubernetes Operator Environment Variables.
