func FullConfigProcess ¶

func FullConfigProcess(ctx context.Context, opts Options, patches []string) (*bundle.Bundle, machine.Type, error)

FullConfigProcess handles the full process of creating and updating the Bundle.

func InitializeConfigBundle ¶

func InitializeConfigBundle(opts Options) (*bundle.Bundle, error)

Function to initialize configuration settings

func MergeFileAsPatch ¶ added in v0.25.0

func MergeFileAsPatch(rendered []byte, patchFile string) ([]byte, error)

MergeFileAsPatch overlays the YAML body of patchFile onto rendered using Talos's strategic-merge config patcher.

patchFile is a node file: its first line is the talm modeline (a YAML comment) followed by an arbitrary Talos config patch (typically machine.* fields the user wants pinned per node). When the file contains only the modeline (or is otherwise empty after stripping comments and whitespace) the function returns rendered unchanged — short-circuiting Talos's configpatcher which would otherwise route the empty patch through JSON6902 and reject any multi-document rendered config (the v1.12+ output format) outright.

Note that for non-empty patches the patcher round-trips rendered through its config loader, normalising YAML formatting and dropping comments. This is acceptable for the apply path (the result goes straight to ApplyConfiguration) but unsuitable for human-facing output such as `talm template` — which is why the template subcommand does not call this helper.

func NodeFileHasOverlay ¶ added in v0.25.0

func NodeFileHasOverlay(patchFile string) (bool, error)

NodeFileHasOverlay reports whether a node file carries a non-empty per-node body below its modeline. The apply path uses this to reject multi-node node files that would otherwise stamp the same pinned hostname/address/VIP onto every target.

func NormalizeTemplatePath ¶ added in v0.19.1

func NormalizeTemplatePath(p string) string

NormalizeTemplatePath converts OS-specific path separators to forward slash. Helm engine's Render() returns map keys with forward slashes regardless of OS, so input paths must be normalized to match.

func Render ¶

func Render(ctx context.Context, c *client.Client, opts Options) ([]byte, error)

Render executes the rendering of templates based on the provided options.

func SerializeConfiguration ¶

func SerializeConfiguration(configBundle *bundle.Bundle, machineType machine.Type) ([]byte, error)

Function for serializing the configuration
