Functions ¶

func AppendVersionTag ¶ added in v0.2.0

func AppendVersionTag(tags *map[string]string)

AppendVersionTag appends the lokoctl-version tag to a given tags map.

func CheckCPUManagerPolicy ¶ added in v0.9.0

func CheckCPUManagerPolicy(wpCPUMgrVals map[string]string) hcl.Diagnostics

CheckCPUManagerPolicy takes a map with key as worker pool name and value as the CPU Manager Policy value. This function checks if the values are valid for Kubernetes.

func CommonControlPlaneCharts ¶ added in v0.4.0

func CommonControlPlaneCharts(c ControlPlanCharts) []helm.LokomotiveChart

CommonControlPlaneCharts returns a list of control plane Helm charts to be deployed for all platforms.

func ControlPlaneChart ¶ added in v0.4.0

func ControlPlaneChart(name string) (*chart.Chart, error)

ControlPlaneChart is a convenience function which returns a pointer to a chart.Chart representing the control plane element named name.

func WorkerPoolNamesUnique ¶ added in v0.6.0

func WorkerPoolNamesUnique(pools []WorkerPool) hcl.Diagnostics

WorkerPoolNamesUnique takes a slice of worker pools and checks if they all have unique names. If not, error diagnostic is returned.

Types ¶

type ControlPlanCharts ¶ added in v0.9.0

type ControlPlanCharts struct {
	Kubelet      bool
	NodeLocalDNS bool
}

ControlPlanCharts struct allows the client to enable/disable specific control plane components based on the user input.

type Meta ¶ added in v0.2.0

type Meta struct {
	AssetDir             string
	ExpectedNodes        int
	Managed              bool
	ControlplaneCharts   []helm.LokomotiveChart
	ControllerModuleName string
	DaemonSets           []Workload
	Deployments          []Workload
}

Meta is a generic information format about the platform.

type Platform ¶

type Platform interface {
	LoadConfig(*hcl.Body, *hcl.EvalContext) hcl.Diagnostics
	Apply(*terraform.Executor) error
	ApplyWithoutParallel(*terraform.Executor) error
	Destroy(*terraform.Executor) error
	Initialize(*terraform.Executor) error
	Meta() Meta
}

Platform describes single environment, where cluster can be installed

type PlatformWithPostApplyHook ¶ added in v0.4.0

type PlatformWithPostApplyHook interface {
	PostApplyHook(kubeconfig []byte) error
}

PlatformWithPostApplyHook runs code after Terraform finishes applying. This allows running sanity checks on the newly created cluster. Implementing this interface is optional for platforms.

type WorkerPool ¶ added in v0.6.0

type WorkerPool interface {
	Name() string
}

WorkerPool describes common functionality between worker pools implementations.

type Workload ¶ added in v0.8.0

type Workload struct {
	Name      string
	Namespace string
}

Workload is a generic struct which can be used to construct a reference to Deployment, DaemonSet, StatefulSet etc. objects.

func CommonDaemonSets ¶ added in v0.8.0

func CommonDaemonSets(controllersCount int, selfHostedKubeletDisabled bool) []Workload

CommonDaemonSets returns common DaemonSets for all Lokomotive platforms.

Number of DaemonSets depends on number of controller nodes in the cluster and if self-hosted kubelet is enabled.

func CommonDeployments ¶ added in v0.8.0

func CommonDeployments(controllersCount int) []Workload

CommonDeployments returns common Deployments for all self-hosted Lokomotive platforms.

Number of Deployments depends on number of controller nodes in the cluster.
