From 3c107e3c79d34cdfb03bc836b39d2f3fc0d6502c Mon Sep 17 00:00:00 2001 From: Elwin Cheng Date: Wed, 18 Feb 2026 14:13:46 -0800 Subject: [PATCH] Add querying container logs API with authentication and tests - Implemented `getJobLogs` endpoint requiring Bearer token authentication. - Added `requireAuth` middleware to enforce authentication for protected routes. - Created comprehensive tests for job logs retrieval, including scenarios for valid and invalid authentication, missing job logs, and query parameters. - Updated `DockerMgr` to support container naming for log retrieval. - Enhanced error handling and logging for better traceability. --- src/api.go | 61 +++++++++++ src/api_test.go | 216 +++++++++++++++++++++++++++++++++++++ src/container_job_test.go | 2 +- src/docker/docker.go | 78 +++++++++++++- src/docker/docker_test.go | 63 +++++++++-- src/int_test.go | 27 +++-- src/job_scheduling_test.go | 2 +- src/supervisor.go | 13 ++- 8 files changed, 435 insertions(+), 27 deletions(-) create mode 100644 src/api_test.go diff --git a/src/api.go b/src/api.go index 15b29d1..219d4d0 100644 --- a/src/api.go +++ b/src/api.go @@ -26,6 +26,7 @@ type App struct { wg sync.WaitGroup log *slog.Logger statusRegistry *StatusRegistry + authToken string // if set, Bearer token required for protected endpoints } func NewApp(redisAddr, gpuType string, log *slog.Logger) *App { @@ -36,6 +37,8 @@ func NewApp(redisAddr, gpuType string, log *slog.Logger) *App { consumerID := fmt.Sprintf("worker_%d", os.Getpid()) supervisor := NewSupervisor(redisAddr, consumerID, gpuType, log) + authToken := os.Getenv("AUTH_TOKEN") + mux := http.NewServeMux() a := &App{ redisClient: client, @@ -44,12 +47,14 @@ func NewApp(redisAddr, gpuType string, log *slog.Logger) *App { httpServer: &http.Server{Addr: ":3000", Handler: mux}, log: log, statusRegistry: statusRegistry, + authToken: authToken, } mux.HandleFunc("/auth/login", a.login) mux.HandleFunc("/auth/refresh", a.refresh) mux.HandleFunc("/jobs", a.handleJobs) mux.HandleFunc("/jobs/status", a.getJobStatus) + mux.HandleFunc("/jobs/logs/", a.requireAuth(a.getJobLogs)) mux.HandleFunc("/supervisors/status", a.getSupervisorStatus) mux.HandleFunc("/supervisors/status/", a.getSupervisorStatusByID) mux.HandleFunc("/supervisors", a.getAllSupervisors) @@ -297,6 +302,62 @@ func (a *App) getSupervisorStatusByID(w http.ResponseWriter, r *http.Request) { } } +// requireAuth wraps a handler and enforces Bearer token authentication. +// If AUTH_TOKEN is not set, returns 503 (logs feature not configured). +// If Authorization header is missing or invalid, returns 401. +func (a *App) requireAuth(next http.HandlerFunc) http.HandlerFunc { + return func(w http.ResponseWriter, r *http.Request) { + if a.authToken == "" { + a.log.Warn("job logs requested but AUTH_TOKEN not configured") + http.Error(w, "Logs require authentication to be configured", http.StatusServiceUnavailable) + return + } + auth := r.Header.Get("Authorization") + if auth == "" { + http.Error(w, "Authorization header required", http.StatusUnauthorized) + return + } + const prefix = "Bearer " + if !strings.HasPrefix(auth, prefix) || strings.TrimSpace(strings.TrimPrefix(auth, prefix)) != a.authToken { + http.Error(w, "Invalid or expired token", http.StatusUnauthorized) + return + } + next(w, r) + } +} + +func (a *App) getJobLogs(w http.ResponseWriter, r *http.Request) { + if r.Method != http.MethodGet { + http.Error(w, "Method not allowed", http.StatusMethodNotAllowed) + return + } + + path := strings.TrimPrefix(r.URL.Path, "/jobs/logs/") + jobID := strings.Trim(path, "/") + if jobID == "" { + jobID = r.URL.Query().Get("id") + } + if jobID == "" { + http.Error(w, "Job ID is required", http.StatusBadRequest) + return + } + + a.log.Info("getJobLogs handler accessed", "job_id", jobID, "remote_address", r.RemoteAddr) + + logs, err := a.supervisor.GetContainerLogsForJob(jobID) + if err != nil { + a.log.Error("failed to get job logs", "job_id", jobID, "error", err) + http.Error(w, fmt.Sprintf("Logs not available for job: %s (container must be running)", jobID), http.StatusNotFound) + return + } + + w.Header().Set("Content-Type", "text/plain;
