Kubernetes - Jimmy Song

When installing on Kubernetes, these configuration settings can be used to override the default Kubernetes configuration. Kubernetes configuration can be set on each component in the install API using the kubeSpec field.

The API allows for customization of every field in the rendered Kubernetes manifests. The more common configuration fields, such as resources and service type, are supported directly; and can be configured like so:

apiVersion: install.tetrate.io/v1alpha1
kind: ManagementPlane
metadata:
  name: managementplane
spec:
  hub: docker.io/tetrate
  components:
    apiServer:
      kubeSpec:
        service:
          type: LoadBalancer
        deployment:
          resources:
            limits:
              memory: 750Mi
            requests:
              memory: 500Mi

All components have a deployment and service object. Some, such as apiServer, also have a job object associated with them. This can be configured in a similar manner:

apiVersion: install.tetrate.io/v1alpha1
kind: ManagementPlane
metadata:
  name: managementplane
spec:
  hub: docker.io/tetrate
  components:
    apiServer:
      kubeSpec:
        job:
          podAnnotations:
            annotation-key: annotation-value

Not all fields in a Kubernetes manifest can be configured directly. This is to avoid re-implementing the entire Kubernetes API within the install API. Instead, the kubeSpec object provides an overlays mechanism. This field is applied after the operator renders the initial manifests and enables support for customization of any field in a rendered manifest.

Overlays can be applied by selecting the Kubernetes object you wish to overlay and then describe a list of patches you wish to apply. For example, to add a hostPort on port 8443 to the frontEnvoy component, do the following:

apiVersion: install.tetrate.io/v1alpha1
kind: ManagementPlane
metadata:
  name: managementplane
spec:
  hub: docker.io/tetrate
  components:
    frontEnvoy:
      kubeSpec:
        overlays:
        - apiVersion: apps/v1
          kind: Deployment
          name: envoy
          patches:
          - path:
          spec.template.spec.containers.[name:envoy].ports.[containerPort:8443].hostPort
            value: 8443

The path refers to the location of the field in the Kubernetes object you with to patch. The format is a.[key1:value1].b.[:value2]. Where [key1:value1] is a selector for a key-value pair to identify a list element and [:value] is a value selector to identify a list element in a leaf list. All path intermediate nodes must exist.

Overlays are inspired by and bear a loose resemblance to [kustomize](https://kustomize.io/). We use the library from the Istio Operator. For more examples of how to construct paths take a look at the tests in the upstream.

Field	Description	Validation Rule
binaryDirectory	string Directory on the host to install the CNI binary. Must be the same as the environment’s `--cni-bin-dir` setting (kubelet parameter).	–
configurationDirectory	string Directory on the host to install the CNI config. Must be the same as the environment’s `--cni-conf-dir` setting (kubelet parameter).	–
chained	bool Whether to deploy the configuration file as a plugin chain or as a standalone file in the configuration directory. Some Kubernetes flavors (e.g. OpenShift) do not support the chain approach.	–
configurationFileName	string Leave unset to auto-find the first file in the `cni-conf-dir` (as kubelet does). Primarily used for testing install-cni plugin configuration. If set, `install-cni` will inject the plugin configuration into this file in the `cni-conf-dir`.	–
clusterRole	string The ClusterRole Istio CNI will bind to in the ControlPlane namespace. This is useful if you use Pod Security Policies and want to allow `istio-cni` to run as privileged Pods.	–
revision	string The revisioned istio-operator that will reconcile the Istio CNI component. A revision can only be specified when Isolation Boundaries are enabled and configured with at least one revision. Revision specified here must be an enabled revision under `xcp.isolationBoundaries`. If not provided, it defaults to the latest enabled revision based on their corresponding tsbVersion. If multiple such revisions are found, revision names are alphabetically sorted and the first revision is considered as the default.	–
