Summary

  • add brev ports ls <instance-or-node> for Brev-managed instances and registered nodes
  • display HTTP applications and raw network mappings in human-readable tables, with a documented stable --json contract for automation
  • resolve registered nodes by exact ID or case-insensitive name, with exact IDs taking precedence and caller cancellation propagated to node lookup

Why

Brev-managed port mappings available in the Brev console were not exposed through the CLI, making endpoint and access details harder to inspect from scripts and terminal workflows.

Impact

Users can now inspect each mapping’s real port_id, endpoint, authorization or IP restrictions, public port, destination port, protocol, and type without leaving the CLI. The JSON output can be passed to later port-management commands without parsing the human tables.

Compatibility

For managed instances, this command reads the Brev-managed network configuration returned by GetNetworkInfo. It intentionally does not synthesize the console legacy secure-link or firewall fallback rows: those rows use UI-only IDs and cannot be targeted by the CLI update or delete APIs.

If no Brev-managed network configuration is available, the command returns an actionable error explaining that the instance may still be provisioning or may use legacy network access, and directs the user to the console. A connected or disconnected network member with zero mappings remains a valid empty result ([] with --json).

Validation

  • go test -race ./pkg/cmd/ports ./pkg/cmd
  • make fmtcheck vet lint
  • go build -o /tmp/brev-pr441-three-brev .
  • command-help smoke tests for brev ports and brev ports ls

Summary by CodeRabbit

  • New Features

    • Added brev ports ls to list HTTP applications and network port mappings for instances and external nodes.
    • Supports readable table output and optional JSON formatting.
    • Displays protocols, endpoints, access restrictions, authorization, and destination details.
    • Labels network mappings as NETWORK PORTS and reflects Brev-managed configuration.
  • Bug Fixes

    • Improved instance and external-node lookup, including case-insensitive name matching and clearer errors for missing resources.
    • Added context-aware requests and better handling of unavailable or partial network information.

Walkthrough

The PR adds brev ports ls for listing Brev-managed HTTP and network ports on instances or external nodes. It adds target-resolution improvements, JSON and table output, command registration, tests, and CLI documentation.

Changes

Ports command

Layer / File(s) Summary
Context-aware target resolution
pkg/cmd/util/externalnode.go, pkg/cmd/util/util.go, pkg/cmd/util/externalnode_test.go
Workspace and external-node lookup now propagates context, preserves lookup errors, supports exact-ID precedence, and matches names case-insensitively.
Port retrieval and output
pkg/cmd/ports/ports.go, pkg/cmd/ports/ports_test.go, pkg/cmd/cmd.go
The new ports ls command retrieves instance or node port data, normalizes HTTP and network entries, removes the public kind field, and renders JSON or formatted tables.
Command documentation
.agents/skills/brev-cli/SKILL.md, .agents/skills/brev-cli/reference/commands.md
The CLI documentation describes brev ports ls, its target syntax, output fields, and Brev-managed network configuration.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to 67824

The new ports listing is otherwise mergeable, but the current head retains bounded issues: a documentation lint warning, one error path without project error context, and SSH entries shown under a TCP/UDP-only heading. These may reduce documentation consistency, diagnosability, and output clarity, so merge is reasonable with explicit owner follow-up.

Poem

A rabbit checks the ports at dawn,
HTTP carrots neatly drawn.
Nodes resolve with context bright,
JSON and tables line up right.
“Brev ports ls!” the rabbit sings.

Use breverrors.WrapAndTrace for consistency.

Every other error path in this file wraps errors with breverrors.WrapAndTrace. Line 89 uses fmt.Errorf, so this error carries no stack trace. The added context is useful. Keep the context and wrap the result.
