func FileFromSystemdUnitDropin(unit types.Unit, dropin types.SystemdDropin, runtime bool) (*FetchOp, error)

type Util 

type Util struct {
	DestDir string // directory prefix to use in applying fs paths.
	Root    string // path to rootfs for resolving uids and gids
	IsRoot  bool   // whether or not DestDir is the root filesystem
	Fetcher resource.Fetcher
	*log.Logger
}

Util encapsulates logging and destdir indirection for the util methods.

func (Util) AuthorizeSSHKeys 

func (u Util) AuthorizeSSHKeys(c types.PasswdUser) error

Add the provided SSH public keys to the user's authorized keys.

func (Util) CheckIfUserExists added in v0.15.0 

func (u Util) CheckIfUserExists(c types.PasswdUser) (bool, error)

CheckIfUserExists will return Info log when user is empty

func (Util) CreateGroup 

func (u Util) CreateGroup(g types.PasswdGroup) error

CreateGroup creates the group as described.

func (Util) DeletePathOnOverwrite added in v0.21.0 

func (u Util) DeletePathOnOverwrite(n types.Node) error

func (Util) DisableUnit added in v0.17.0 

func (u Util) DisableUnit(unit types.Unit) error

func (Util) EnableRuntimeUnit added in v0.27.0 

func (u Util) EnableRuntimeUnit(unit types.Unit, target string) error

presets link in /etc, which doesn't make sense for runtime units Related: https://github.com/coreos/ignition/issues/588

func (Util) EnableUnit 

func (u Util) EnableUnit(unit types.Unit) error

func (Util) EnsureUser added in v0.15.0 

func (u Util) EnsureUser(c types.PasswdUser) error

func (Util) JoinPath 

func (u Util) JoinPath(path ...string) (string, error)

JoinPath returns a path into the context ala filepath.Join(d, args) If u.IsRoot is true, it resolves symlinks as if they were rooted at u.DestDir. This means that the resulting path will always be under u.DestDir. If u.IsRoot is false, it fails if a symlink resolves such that it would escape u.DestDir. The last element of the path is never followed.

func (Util) MaskUnit 

func (u Util) MaskUnit(unit types.Unit) error

func (Util) PathExists added in v0.27.0 

func (u Util) PathExists(path string) (bool, error)

PathExists returns true if a node exists within DestDir, false otherwise. Any error other than ENOENT is treated as fatal.

func (Util) PerformFetch added in v0.17.0 

func (u Util) PerformFetch(f *FetchOp) error

PerformFetch performs a fetch operation generated by PrepareFetch, retrieving the file and writing it to disk. Any encountered errors are returned.

func (Util) PrepareFetch added in v0.17.0 

func (u Util) PrepareFetch(l *log.Logger, f types.File) *FetchOp

PrepareFetch converts a given logger, http client, and types.File into a FetchOp. This includes operations such as parsing the source URL, generating a hasher, and performing user/group name lookups. If an error is encountered, the issue will be logged and nil will be returned.

func (Util) ResolveNodeUidAndGid added in v0.21.0 

func (u Util) ResolveNodeUidAndGid(n types.Node, defaultUid, defaultGid int) (int, int, error)

ResolveNodeUidAndGid attempts to convert a types.Node into a concrete uid and gid. If the node has the User.ID field set, that's used for the uid. If the node has the User.Name field set, a username -> uid lookup is performed. If neither are set, it returns the passed in defaultUid. The logic is identical for gids with equivalent fields.

func (Util) SetPasswordHash 

func (u Util) SetPasswordHash(c types.PasswdUser) error

SetPasswordHash sets the password hash of the specified user.
