Description

The REST API endpoint for reading Docker container logs returns HTTP 500 Internal Server Error, making it impossible to retrieve container logs programmatically.

Related issues: #244 (Pull Stack 500), #349 (Pull image 500) — these suggest broader REST API stability issues.

Environment

Komodo Core/Periphery: v2.2.0
Periphery running on TrueNAS Scale (systemd mode)

Reproduction

Have a running container on a server managed by Komodo
Call the REST API to get container logs:

import json, urllib.request

body = json.dumps({"server": "Local", "container": "<container_id>", "tail": 50}).encode()
req = urllib.request.Request("https://komodo.example.com/read/DockerContainerLogs", data=body, method="POST")
req.add_header("Content-Type", "application/json")
req.add_header("X-Api-Key", "...")
req.add_header("X-Api-Secret", "...")
urllib.request.urlopen(req)
# → HTTP Error 500: Internal Server Error

Server returns:

{"error":"unknown variant `DockerContainerLogs`, expected one of `GetVersion`, `GetCoreInfo`, `ListSecrets`, ..."}

Expected behavior

The API should return container logs (stdout + stderr) as a JSON response.

Actual behavior

HTTP 500 with unknown variant error. The error message lists valid endpoint names, but none of them appear to be a container logs endpoint.

Notes

Terminal-based log viewing through the Komodo UI (websocket) works fine.
This is specifically about the REST API — there does not seem to be a valid endpoint for reading container logs.
Related: #1198 (feature request for real-time image pull progress) suggests logging/observability via API is limited.

Suggestion

Either:

Add a working DockerContainerLogs read endpoint that returns container stdout/stderr, or
Document the correct endpoint name if it exists under a different name, or
If logs are only available through websocket terminals, document that limitation.
