From f66472fd37904921f92429e408a74a848c1e5af1 Mon Sep 17 00:00:00 2001 From: Jon Chery Date: Mon, 3 Aug 2026 19:59:51 +0000 Subject: [PATCH] feat(P03): doctor os + doctor proxmox + audit logging Extends orca doctor with two new checks (REQ-052): - doctor os: re-runs OS detection from /etc/os-release, compares to stored localhost node's os field. Drift = WARN (re-run orca init); match = PASS; missing localhost node = FAIL. - doctor proxmox: iterates kind=proxmox nodes, SSH-probes each with `pveversion` (3s timeout per node, clones Network() pattern). Zero proxmox nodes = WARN; reachable = PASS; unreachable = FAIL. Changes: - internal/osdetect: new shared package (Detect + ParseID) extracted from internal/cli to avoid import cycle (cli + doctor both need it) - internal/cli/osdetect.go: thin wrapper delegating to osdetect package - internal/doctor/doctor.go: OS() and Proxmox() checks; All() extended; probeProxmoxPVEVersion uses orca SSH key + knownhosts TOFU - internal/cli/doctor.go: doctor os + doctor proxmox subcommands (--json) - internal/doctor/doctor_test.go: 5 new tests (OS match/drift/missing, proxmox no-nodes/unreachable) E2E: orca init -> orca doctor shows 6 PASS / 1 WARN (proxmox=none) / 1 FAIL (network=daemon not running). doctor os --json valid. ---ci--- project: orca phase: 3 milestone: v0.6 status: execute ---/ci--- --- .ciagent/CHECKPOINT.json | 6 +- internal/cli/doctor.go | 30 ++++- internal/cli/osdetect.go | 60 +--------- internal/cli/osdetect_test.go | 140 ++-------------------- internal/doctor/doctor.go | 179 +++++++++++++++++++++++++++++ internal/doctor/doctor_test.go | 151 ++++++++++++++++++++++++ internal/osdetect/osdetect.go | 63 ++++++++++ internal/osdetect/osdetect_test.go | 103 +++++++++++++++++ 8 files changed, 544 insertions(+), 188 deletions(-) create mode 100644 internal/osdetect/osdetect.go create mode 100644 internal/osdetect/osdetect_test.go diff --git a/.ciagent/CHECKPOINT.json b/.ciagent/CHECKPOINT.json index 0225dd8..aff31ba 100644 --- a/.ciagent/CHECKPOINT.json +++ b/.ciagent/CHECKPOINT.json @@ -1,11 +1,11 @@ { - "phase": 2, - "stage": "verify", + "phase": 3, + "stage": "execute", "milestone": "v0.6", "milestone_slug": "node-bootstrap-proxmox", "phase_role": "execution", "attempts": 0, - "updated_at": "2026-08-03T19:57:00Z", + "updated_at": "2026-08-03T20:00:00Z", "milestone_complete": false, "next_milestone": null } \ No newline at end of file diff --git a/internal/cli/doctor.go b/internal/cli/doctor.go index 15f0e39..41da7a9 100644 --- a/internal/cli/doctor.go +++ b/internal/cli/doctor.go @@ -69,7 +69,35 @@ var doctorDBCmd = &cobra.Command{ }, } +var doctorOSCmd = &cobra.Command{ + Use: "os", + Short: "Run the OS detection self-check (v0.6 P03)", + RunE: func(cmd *cobra.Command, args []string) error { + c := doctor.OS() + r, msg := c.Run(cmd.Context()) + if jsonOutput { + return printJSON(doctor.CheckResult{Name: c.Name, Result: r, Message: msg}) + } + fmt.Fprintf(cmd.OutOrStdout(), "%-20s %-5s %s\n", c.Name, r, msg) + return nil + }, +} + +var doctorProxmoxCmd = &cobra.Command{ + Use: "proxmox", + Short: "Run the proxmox node reachability self-check (v0.6 P03)", + RunE: func(cmd *cobra.Command, args []string) error { + c := doctor.Proxmox() + r, msg := c.Run(cmd.Context()) + if jsonOutput { + return printJSON(doctor.CheckResult{Name: c.Name, Result: r, Message: msg}) + } + fmt.Fprintf(cmd.OutOrStdout(), "%-20s %-5s %s\n", c.Name, r, msg) + return nil + }, +} + func init() { - doctorCmd.AddCommand(doctorCertCmd, doctorNetworkCmd, doctorDBCmd) + doctorCmd.AddCommand(doctorCertCmd, doctorNetworkCmd, doctorDBCmd, doctorOSCmd, doctorProxmoxCmd) rootCmd.AddCommand(doctorCmd) } diff --git a/internal/cli/osdetect.go b/internal/cli/osdetect.go index 62b396e..f9716aa 100644 --- a/internal/cli/osdetect.go +++ b/internal/cli/osdetect.go @@ -1,60 +1,10 @@ package cli -import ( - "bufio" - "os" - "strings" -) +import "git.cloudinit.dev/coreci/orca/internal/osdetect" -// osReleasePaths are checked in order for the os-release file.
