    Hello! n8n reads from Docker environment 3 key values:

    1. timezone
    2. key to encrypt all of the credentials
    3. retention logs policy

    From what I can see, since my credentials survive n8n instance restart, item number 2 seems to be good, but since my cron node seems to be executing at the wrong time, the time zone is not - could you please, check / fix that?

    And one more thing - what is the logs retention policy? How many hours of logs are kept?

    Thank you! And special thanks for adding n8n to the apps!

    @potemkin_ai looks like you can set GENERIC_TIMEZONE as suggested by https://docs.n8n.io/getting-started/installation/docker-quickstart.html#setting-timezone . On Cloudron, you can edit /app/data/env using the file manager and restart the app.

        As for the logs, we keep last 10MB of logs per app.

          @girish thank you!

          Is there a way for Cloudron to pick up for that purpose a Time Zone that I'm configuring at the settings page?

            @potemkin_ai Currently, no, but I think that's a good idea worth investigating!

              @girish thanks, yes, that would be very nice, if n8n container's time zone (and probably other services) would be regulated that way.

              As for the logs - I realized that we might speak about different kind of logs here - n8n stores execution logs, that might fill up the disk very quickly: https://community.n8n.io/t/hard-disk-full-where-to-delete-logs/2298

              Here are the environment variables that seems like of the most importance at n8n:

              GENERIC_TIMEZONE=
              WEBHOOK_TUNNEL_URL=https://FQDN/ #this one, to make sure webhook URL will work fine
              N8N_ENCRYPTION_KEY=.. #to avoid loosing credentials on docker restart
              
              #clear execution logs
              EXECUTIONS_DATA_PRUNE=true
              EXECUTIONS_DATA_MAX_AGE=672

                @potemkin_ai ah, i see. Do you think the defaults you have provided are reasonable? If so, I can put them as part of the default install.

                  @girish absolutely!

                  It makes n8n to perform in right timezone, have proper webhook URL, keep credentials (not loosing then during the docker rebuild), avoid disk overflow from the executions log.

                    OK, I have put this as the default for new installations.

                        @potemkin_ai I’m struggling to get the time zone set up. Do you have any suggestions as to what I did wrong? These are my env settings:

                        Set the logging level to 'debug'
                        export EXECUTIONS_DATA_SAVE_MANUAL_EXECUTIONS=true
                        export EXECUTIONS_DATA_SAVE_ON_ERROR=all
                        export EXECUTIONS_DATA_SAVE_ON_SUCCESS=all
                        export N8N_LOG_LEVEL=info
                        
                        GENERIC_TIMEZONE='Europe/Berlin'
                        TZ='Europe/Berlin'
                        WEBHOOK_TUNNEL_URL=https://top.level.domain/
                        N8N_ENCRYPTION_KEY='redacted'
