Functions

func New

func New() types.Backend

New returns a new Kubernetes Backend.

Types

type BackendOptions

type BackendOptions struct {
	Resources          Resources         `mapstructure:"resources"`
	RuntimeClassName   *string           `mapstructure:"runtimeClassName"`
	ServiceAccountName string            `mapstructure:"serviceAccountName"`
	Labels             map[string]string `mapstructure:"labels"`
	Annotations        map[string]string `mapstructure:"annotations"`
	NodeSelector       map[string]string `mapstructure:"nodeSelector"`
	Tolerations        []Toleration      `mapstructure:"tolerations"`
	SecurityContext    *SecurityContext  `mapstructure:"securityContext"`
}

BackendOptions defines all the advanced options for the kubernetes backend.

type Resources

type Resources struct {
	Requests map[string]string `mapstructure:"requests"`
	Limits   map[string]string `mapstructure:"limits"`
}

Resources defines two maps for kubernetes resource definitions.

type SecProfile

type SecProfile struct {
	Type             SecProfileType `mapstructure:"type"`
	LocalhostProfile string         `mapstructure:"localhostProfile"`
}

type SecProfileType

type SecProfileType string

const (
	SecProfileTypeRuntimeDefault SecProfileType = "RuntimeDefault"
	SecProfileTypeLocalhost      SecProfileType = "Localhost"
)

type SecurityContext

type SecurityContext struct {
	Privileged      *bool       `mapstructure:"privileged"`
	RunAsNonRoot    *bool       `mapstructure:"runAsNonRoot"`
	RunAsUser       *int64      `mapstructure:"runAsUser"`
	RunAsGroup      *int64      `mapstructure:"runAsGroup"`
	FSGroup         *int64      `mapstructure:"fsGroup"`
	SeccompProfile  *SecProfile `mapstructure:"seccompProfile"`
	ApparmorProfile *SecProfile `mapstructure:"apparmorProfile"`
}

type SecurityContextConfig

type SecurityContextConfig struct {
	RunAsNonRoot bool
}

type TaintEffect

type TaintEffect string

const (
	TaintEffectNoSchedule       TaintEffect = "NoSchedule"
	TaintEffectPreferNoSchedule TaintEffect = "PreferNoSchedule"
	TaintEffectNoExecute        TaintEffect = "NoExecute"
)

type Toleration

type Toleration struct {
	Key               string             `mapstructure:"key"`
	Operator          TolerationOperator `mapstructure:"operator"`
	Value             string             `mapstructure:"value"`
	Effect            TaintEffect        `mapstructure:"effect"`
	TolerationSeconds *int64             `mapstructure:"tolerationSeconds"`
