func ByteToString ¶
func ReadJSONFile ¶
func WriteJSONFile ¶
WriteJSONFile marshalls and writes the given data to a JSON file
Types ¶
type ContainerConfig ¶
type ContainerConfig struct {
ID string `json:"id"`
Name string `json:"name"`
RootfsImage string `json:"rootfsImage,omitempty"`
RootfsImageRef string `json:"rootfsImageRef,omitempty"`
RootfsImageName string `json:"rootfsImageName,omitempty"`
OCIRuntime string `json:"runtime,omitempty"`
CreatedTime time.Time `json:"createdTime"`
CheckpointedAt time.Time `json:"checkpointedTime"`
RestoredAt time.Time `json:"restoredTime"`
Restored bool `json:"restored"`
}
This is a reduced copy of what Podman uses to store checkpoint metadata
func ReadContainerCheckpointConfigDump ¶
func ReadContainerCheckpointConfigDump(checkpointDirectory string) (*ContainerConfig, string, error)
type ContainerdStatus ¶
type ContainerdStatus struct {
CreatedAt int64
StartedAt int64
FinishedAt int64
ExitCode int32
Pid uint32
Reason string
Message string
}
func ReadContainerCheckpointStatusFile ¶
func ReadContainerCheckpointStatusFile(checkpointDirectory string) (*ContainerdStatus, string, error)
type KubernetesCheckpoint ¶
type KubernetesCheckpoint struct {
Archive string `json:"archive,omitempty"`
Size int64 `json:"size,omitempty"`
Timestamp int64 `json:"timestamp,omitempty"`
}
This structure is used by the KubernetesContainerCheckpointMetadata structure
type KubernetesContainerCheckpointMetadata ¶
type KubernetesContainerCheckpointMetadata struct {
PodFullName string `json:"podFullName,omitempty"`
ContainerName string `json:"containerName,omitempty"`
TotalSize int64 `json:"totalSize,omitempty"`
Checkpoints []KubernetesCheckpoint `json:"checkpoints"`
}
This structure is the basis for Kubernetes to track how many checkpoints for a certain container have been created.
