How to show django logging and error log in Cloud Run's log?

Question

I'm using Django, uwsgi and nginx in Cloud Run.

A Cloud Run service can't show django logging and error log. That's why Error Report can't use ,too.

Cloud Run log is like this. It can not see stack trace... I can't know what error happened in the server.

This is my settings.

Django settings.py

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'formatters': {
        'local': {
            'format': "[%(asctime)s] %(levelname)s [%(name)s.%(funcName)s:%(lineno)d] %(message)s"
        },

        'verbose': {
            'format': '{message}',
            'style': '{',
        },
    },
    'filters': {
        'require_debug_false': {
            '()': 'django.utils.log.RequireDebugFalse',
        }
    },
    'handlers': {
        'console': {
            'class': 'logging.StreamHandler',
            'formatter': 'local',
        },
    },
    'root': {
        'handlers': ['console'],
        'level': 'WARNING',
    },
    'loggers': {
        'users': {
            'handlers': ['console'],
            'level': 'DEBUG',
            'propagate': False,
        },
        'django': {
            'handlers': ['console'],
            'level': 'INFO',
            'propagate': False,
        },
        'django.db.backends': {
            'handlers': ['console'],
            'level': 'INFO',
            'propagate': False,
        },
        'mail_admins': {
            'level': 'ERROR',
            'filters': ['require_debug_false'],
            'class': 'django.utils.log.AdminEmailHandler'
        }
    }
}

# Graceful stop, see http://nginx.org/en/docs/control.html
stopsignal=QUIT

Cloud Run get /var and /dev directorys logs, right? document

Why this setting can't get django logging result and error log for example 500 error.

I wrote loggin like this.

logger = logging.getLogger(__name__)
logge.info('hello world')

Howeve this log can not see in Cloud Run's log.

Please help me!

Answer 1

I found my mistake. I didn't change server_name in nginx.conf

I changed this line of the file form

server_name .example.com;

to

server_name MY_DOMAIN;

Then update Cloud Run. I can see the error log now!

Error Report works fine ,too!

Is this means that did not connect nginx?
