How can I have better logs ?

Dagger exposes 2 logging format options:

  • --log-format <auto|plain|tty|json>

The default mode is auto. If you want to keep each actions' logs, use the plain mode

  • --log-level <panic|fatal|error|warn|info|debug|trace>

debug is useful to check whether an explicit dependency has been found between two actions and see CUE DAG at run time.

You can also export these options as env variables:

export DAGGER_LOG_FORMAT="plain"
export DAGGER_LOG_LEVEL="debug"
