Logging

dns-updater uses zerolog for logging. Logging is configured in config.yaml under the log section.

Configuration​

log:
  level: info
  type: pretty

log.level​

log.level controls the global log level. It is parsed using zerolog.ParseLevel(...).

If you provide an invalid value, dns-updater falls back to info and emits a warning. Common values include: debug, info, warn, error.

Example:

log:
  level: debug
  type: pretty

log.type​

log.type controls the log output format/destination.

Supported values:

  • pretty Human-readable console output.

  • json Structured JSON logs to stdout (this is also the default if log.type is not recognized).

  • file Currently not a true file logger. The code contains commented example logic for writing to a file, but the current implementation still logs to stdout.

Defaults​

If log is omitted, these defaults are applied:

log:
  level: info
  type: pretty
