How to update CVAT

Before upgrading, please follow the official docker manual and backup all CVAT volumes.

To update CVAT, you should clone or download the new version of CVAT and rebuild the CVAT docker images as usual.

docker-compose build

and run containers:

docker-compose up -d

Sometimes the update process takes a lot of time due to changes in the database schema and data. You can check the current status with docker logs cvat. Please do not terminate the migration and wait till the process is complete.

Make sure there aren't error messages from Elasticsearch:

docker logs cvat_elasticsearch

    ports:

Please don't forget to include this file in docker-compose commands using the -f option (in some cases it can be omitted).
