Overview ¶

Package logger configures structured logging for the agent using log/slog.

Design decisions:

JSON output by default for log aggregation (journald, Loki, Datadog)
Text output when LOG_FORMAT=text (local development)
Level controlled by LOG_LEVEL env var (debug, info, warn, error)
Structured fields: environment, phase, digest, duration included consistently

Phase constants for structured log fields. Using constants prevents typos and enables log-based alerting rules.

Functions ¶

func FromContext ¶

func FromContext(ctx context.Context) *slog.Logger

FromContext retrieves the logger stored in ctx. Falls back to the default slog logger if none is stored.

func Setup ¶

func Setup() *slog.Logger

Setup configures the default global slog logger. Call once at startup before spawning goroutines.

func WithContainerName ¶

func WithContainerName(logger *slog.Logger, containerName string) *slog.Logger

WithContainerName returns a child logger with the environment field pre-set. All log lines emitted from the reconciler for an environment will carry this.

func WithContext ¶

func WithContext(ctx context.Context, logger *slog.Logger) context.Context

WithContext stores logger in ctx, enabling logger retrieval in deep call stacks.
