Types

type CtrSpecGenOptions

type CtrSpecGenOptions struct {
	// Annotations from the Pod
	Annotations map[string]string
	// Container as read from the pod yaml
	Container v1.Container
	// Image available to use (pulled or found local)
	Image *libimage.Image
	// Volumes for all containers
	Volumes map[string]*KubeVolume
	// PodID of the parent pod
	PodID string
	// PodName of the parent pod
	PodName string
	// PodInfraID as the infrastructure container id
	PodInfraID string
	// ConfigMaps the configuration maps for environment variables
	ConfigMaps []v1.ConfigMap
	// SeccompPaths for finding the seccomp profile path
	SeccompPaths *KubeSeccompPaths
	// RestartPolicy defines the restart policy of the container
	RestartPolicy string

	NetNSIsHost bool
	// SecretManager to access the secrets
	SecretsManager *secrets.SecretsManager
	// LogDriver which should be used for the container
	LogDriver string
	// Labels define key-value pairs of metadata
	Labels map[string]string
	//
	IsInfra bool
	// InitContainerType sets what type the init container is
	// Note: When playing a kube yaml, the inti container type will be set to "always" only
	InitContainerType string
}

type KubeSeccompPaths

type KubeSeccompPaths struct {
	// contains filtered or unexported fields
}

KubeSeccompPaths holds information about a pod YAML's seccomp configuration it holds both container and pod seccomp paths nolint:golint

func InitializeSeccompPaths

func InitializeSeccompPaths(annotations map[string]string, profileRoot string) (*KubeSeccompPaths, error)

InitializeSeccompPaths takes annotations from the pod object metadata and finds annotations pertaining to seccomp it parses both pod and container level if the annotation is of the form "localhost/%s", the seccomp profile will be set to profileRoot/%s

func (*KubeSeccompPaths) FindForContainer

func (k *KubeSeccompPaths) FindForContainer(ctrName string) string

FindForContainer checks whether a container has a seccomp path configured for it if not, it returns the podPath, which should always have a value

type KubeVolume

type KubeVolume struct {
	// Type of volume to create
	Type KubeVolumeType
	// Path for bind mount or volume name for named volume
	Source string
}

Create a KubeVolume from a PersistentVolumeClaimVolumeSource

func VolumeFromSource

func VolumeFromSource(volumeSource v1.VolumeSource) (*KubeVolume, error)

Create a KubeVolume from one of the supported VolumeSource
