Types ¶
type Elemental ¶
type Elemental struct {
// contains filtered or unexported fields
}
Elemental is the struct meant to self-contain most utils and actions related to Elemental, like installing or applying selinux
func NewElemental ¶
func (*Elemental) CheckActiveDeployment ¶
CheckActiveDeployment returns true if at least one of the provided filesystem labels is found within the system
func (*Elemental) CopyCloudConfig ¶
CopyCloudConfig will check if there is a cloud init in the config and store it on the target
func (*Elemental) CopyFileImg ¶ added in v0.2.0
CopyFileImg copies the files target as the source of this image. It also applies the img label over the copied image.
func (Elemental) CreateFileSystemImage ¶
CreateFileSystemImage creates the image file for the given image
func (*Elemental) CreateImgFromTree ¶ added in v0.2.0
CreateImgFromTree creates the given image from with the contents of the tree for the given root.
func (Elemental) DeactivateDevices ¶
DeactivateDevice deactivates unmounted the block devices present within the system. Useful to deactivate LVM volumes, if any, related to the target device.
func (*Elemental) DeployImage ¶
DeployImage will deploy the given image into the target. This method creates the filesystem image file and fills it with the correspondant data
func (*Elemental) DeployImgTree ¶ added in v0.2.0
func (e *Elemental) DeployImgTree(img *v1.Image, root string) (info interface{}, cleaner func() error, err error)
DeployImgTree will deploy the given image into the given root tree. Returns source metadata in info, a tree cleaner function and error. The given root will be a bind mount of a temporary directory into the same filesystem of img.File, this is helpful to make the deployment easily accessible in after-* hooks.
func (*Elemental) DumpSource ¶
func (e *Elemental) DumpSource(target string, imgSrc *v1.ImageSource) (info interface{}, err error)
DumpSource sets the image data according to the image source type
func (Elemental) FindKernelInitrd ¶
FindKernelInitrd finds for kernel and intird files inside the /boot directory of a given root tree path. It assumes kernel and initrd files match certain file name prefixes.
func (*Elemental) FormatPartition ¶
FormatPartition will format an already existing partition
func (Elemental) MountImage ¶
MountImage mounts an image with the given mount options
func (Elemental) MountPartition ¶
MountPartition mounts a partition with the given mount options
func (Elemental) MountPartitions ¶
func (e Elemental) MountPartitions(parts v1.PartitionList) error
MountPartitions mounts configured partitions. Partitions with an unset mountpoint are not mounted. Note umounts must be handled by caller logic.
func (Elemental) MountRWPartition ¶
MountRWPartition mounts, or remounts if needed, a partition with RW permissions
func (*Elemental) PartitionAndFormatDevice ¶
func (e *Elemental) PartitionAndFormatDevice(i *v1.InstallSpec) error
PartitionAndFormatDevice creates a new empty partition table on target disk and applies the configured disk layout by creating and formatting all required partitions
func (*Elemental) SelinuxRelabel ¶
SelinuxRelabel will relabel the system if it finds the binary and the context
func (Elemental) SetDefaultGrubEntry ¶
func (e Elemental) SetDefaultGrubEntry(partMountPoint string, imgMountPoint string, defaultEntry string) error
SetDefaultGrubEntry Sets the default_meny_entry value in RunConfig.GrubOEMEnv file at in State partition mountpoint. If there is not a custom value in the os-release file, we do nothing As the grub config already has a sane default
func (Elemental) UnmountImage ¶
UnmountImage unmounts the given image or does nothing if not mounted
func (Elemental) UnmountPartition ¶
UnmountPartition unmounts the given partition or does nothing if not mounted
func (Elemental) UnmountPartitions ¶
func (e Elemental) UnmountPartitions(parts v1.PartitionList) error
UnmountPartitions unmounts configured partitiosn. Partitions with an unset mountpoint are not unmounted.
func (Elemental) UpdateSourceFormISO ¶ added in v0.2.2
UpdateSourceISO downloads an ISO in a temporary folder, mounts it and updates active image to use the ISO squashfs image as source. Returns a cleaner method to unmount and remove the temporary folder afterwards.
