logs

Purpose

This is a sample setup to demonstrate how to configure logging to file in a docker environment. Normaly, the Orthanc logs are going to stderr that is captured by the Docker engine. However, when running Orthanc on a NAS with limited Docker tooling, it might be interesting to redirect logs to a folder that is mounted on the NAS.

Description

This demo contains:

• an Orthanc container that is configured to store its logs in /logs folder thanks to the LOGDIR environment variable. We've also disabled logs deindentification thanks to the DeidentifyLogs option. This is helpful, e.g in order to debug C-Find requests.

Starting the setup

• To start the setup, type: docker-compose up --build

demo

• Note: Since logging output is configured towards a folder, Orthanc will not output anything to stderr and therefore no output will be captured by Docker.
• logs are available on your host machine in /tmp/orthanc-logs-docker/
• if using LOGDIR you'll notice that a new log is created at each startup.
• Note: the LOGDIR and LOGFILE environment variables have been introduced in v 21.9.1 of the orthancteam/orthanc images. Make sure to use a more recent version.
