From eb18b48a7c46456aac8d59940e677636ac03d130 Mon Sep 17 00:00:00 2001 From: Aleksei Sviridkin Date: Tue, 7 Apr 2026 11:26:18 +0300 Subject: [PATCH 01/24] feat(commands): extract GenerateProject for reuse by wizard Extract core project generation logic from init command into an exported GenerateProject function. This enables the upcoming interactive TUI wizard to reuse the same generation logic without duplicating code. Changes: - Add GenerateProject(opts GenerateOptions) function with clean API - Add helper functions: writeFileIfNotExists, writeToFile, writeGitignoreForProject - Simplify interactive_init.go to a stub pending TUI implementation - Add comprehensive tests for GenerateProject covering both presets, force overwrite, invalid preset, and default version Assisted-By: Claude Signed-off-by: Aleksei Sviridkin --- pkg/commands/init.go | 194 ++++++++++++++++++++++++++++++ pkg/commands/init_test.go | 195 +++++++++++++++++++++++++++++++ pkg/commands/interactive_init.go | 36 ++++++ 3 files changed, 425 insertions(+) create mode 100644 pkg/commands/init_test.go create mode 100644 pkg/commands/interactive_init.go diff --git a/pkg/commands/init.go b/pkg/commands/init.go index b3b927dc..b976e888 100644 --- a/pkg/commands/init.go +++ b/pkg/commands/init.go @@ -692,6 +692,200 @@ func init() { // Don't mark preset as required - it's validated in PreRunE based on --encrypt/--decrypt flags } +// GenerateOptions holds options for project generation. +type GenerateOptions struct { + RootDir string + Preset string + ClusterName string + TalosVersion string + Version string // Chart version, e.g. "0.1.0" + Force bool +} + +// GenerateProject creates a new talm project: secrets, talosconfig, preset files, .gitignore, and nodes directory. +// It does not handle encryption — callers should handle that separately if needed. +func GenerateProject(opts GenerateOptions) error { + var ( + versionContract *config.VersionContract + err error + ) + + if opts.TalosVersion != "" { + versionContract, err = config.ParseContractFromVersion(opts.TalosVersion) + if err != nil { + return fmt.Errorf("invalid talos-version: %w", err) + } + } + + secretsBundle, err := secrets.NewBundle(secrets.NewFixedClock(time.Now()), versionContract) + if err != nil { + return fmt.Errorf("failed to create secrets bundle: %w", err) + } + + availablePresets, err := generated.AvailablePresets() + if err != nil { + return fmt.Errorf("failed to get available presets: %w", err) + } + if !isValidPreset(opts.Preset, availablePresets) { + return fmt.Errorf("invalid preset: %s.

wizard.Scanner interface using nmap for host discovery and talosctl for hardware info collection - CommandRunner interface enables mocking exec.Command in tests - Bounded parallelism (max 10 goroutines) for concurrent node queries - Individual node query failures do not abort the overall scan Tests use mock CommandRunner for deterministic, fast execution.

12:05:09 +0300 Subject: [PATCH 05/24] fix(wizard): fix nmap flag and implement real hardware collection - Fix nmap flag: --port is invalid, use -p instead - Rewrite GetNodeInfo to collect hostname, disks, and network interfaces via three separate talosctl commands with JSON output parsing - Add parse_talosctl.go: ParseHostname, ParseDisks, ParseLinks functions that parse NDJSON output from talosctl get commands - Filter non-physical interfaces (loopback, bonds, vlans) - Gracefully handle partial failures (individual command errors don't abort the overall node info collection) - Update all scanner tests for new multi-command flow Assisted-By: Claude Signed-off-by: Aleksei Sviridkin --- pkg/wizard/scan/parse_talosctl.go | 124 ++++++++++++++++ pkg/wizard/scan/parse_talosctl_test.go |

12:12:00 +0300 Subject: [PATCH 08/24] feat(wizard): expand node form, add manual entry, wire generation Complete the wizard implementation: - Expand node config form from 4 to 7 fields: role (editable), hostname, disk, interface, address, gateway, DNS - Add validation for all fields on submit (role, hostname, CIDR, gateway IP, DNS IPs) - First node defaults to controlplane, rest to worker (user can change) - Pre-fill fields from discovered hardware (hostname, disk, interface) - Add 'skip scan' flow: press 's' at CIDR step to enter IPs manually - Manual entry validates IPs, pre-selects all entered nodes - Wire generateFn to build ValuesOverrides from WizardResult and call WriteNodeFiles after project generation - Update all tests: 24 TUI tests covering manual entry, validation, role defaults, and view rendering Assisted-By: Claude Signed-off-by: Aleksei Sviridkin --- pkg/commands/interactive_init.go | 51 +++++- pkg/wizard/tui/model.go | 214 +++++++++++++++++++-----

9779fe1e74d5fefdc22433cc723006acb7dc22d2 Mon Sep 17 00:00:00 2001 From: Aleksei Sviridkin Date: Tue, 7 Apr 2026 12:24:18 +0300 Subject: [PATCH 09/24] refactor(wizard): replace os.Exec with native Go TCP scan and gRPC Remove all external binary dependencies (nmap, talosctl) from the scanner in favor of pure Go implementations: - Replace nmap with Go TCP connect scanner (net.DialTimeout) that enumerates CIDR hosts and probes the Talos API port directly - Replace talosctl subprocess calls with Talos machinery gRPC client: c.Version() for hostname, c.Disks() for block devices, c.Memory() for RAM, helpers.ForEachResource for network links - Add extract.go with pure functions for parsing gRPC protobuf responses into wizard domain types - Add tcpscan.go with CIDR host enumeration (handles /24 through /32, skips network and broadcast addresses) - Delete parse.go, parse_test.go, parse_talosctl.go, parse_talosctl_test.go (no longer needed) - TCP scan tested with real localhost TCP listener - gRPC extraction tested with constructed protobuf structs Zero runtime dependencies on external binaries.

Remove unused WizardResult fields (OIDCIssuerURL, NrHugepages) 9. handleBack from configureNode now calls prepareNodeInputs to restore previous node's data in the input fields 10. enumerateHosts /32 uses ipNet.IP consistently instead of ip Non-blocking: - Remove dead filterPhysicalInterfaces function - Fix fragile port in TestScanTCPPort_NoOpenPort (use closed listener) - Guard empty endpoint in buildValuesOverrides All fixes have corresponding tests.

Eliminate global state race in GenerateProject: extract writeGitignoreForDir(rootDir) instead of mutating Config.RootDir 2. Pass cancellable context to scanNetworkCmd; cancel on Ctrl+C to prevent background goroutine leak during network scanning 3. Reject CIDR ranges larger than /16 in enumerateHosts to prevent allocation of millions of IPs (16M+ for /8) 4.

charset=UTF-8 Content-Transfer-Encoding: 8bit 1. writeGitignoreForDir now accepts kubeconfigName parameter instead of reading from global Config state — eliminates race condition 2. TalosScanner.Timeout field is now used in GetNodeInfo (was dead code) 3. initCmd.RunE now calls GenerateProject for core generation, removing ~100 lines of duplicated logic. Dead functions writeSecretsBundleToFile, validateFileExists, writeToDestination removed 4. ValidateHostname length limit fixed: 63 chars (DNS label) not 253 (FQDN) 5. collectNodeInfo returns informative error when TCP scan finds hosts but none respond as Talos nodes via gRPC 6. WriteNodeFiles sanitizes hostname via filepath.Base to prevent path traversal (e.g. '../escape' becomes 'escape') All fixes have corresponding tests.

GenerateProject now skips existing files silently (Force=false) instead of erroring. Fixes regression where 'talm init' on projects with encrypted files would fail because decrypted files already exist. 2. KubeconfigName passed explicitly via GenerateOptions, removing last global Config dependency from GenerateProject. 3. handleBack from stepConfirm decrements currentNodeIdx and calls prepareNodeInputs — fixes out-of-bounds panic. 4. prevStep uses *step pointer to distinguish nil (no previous) from stepSelectPreset (value 0). Error recovery correctly returns to any step including the first one. 5. Esc from stepScanning cancels the scan context and returns to CIDR step. Fixes context leak where background scan goroutines continued after user navigated away. All fixes have corresponding tests.
