Langtrace supports multiple authentication methods. Make sure to configure the necessary environment variables for your chosen authentication method(s) in the .env file. For detailed instructions, refer to our Authentication guide.

​
Step 3: Start the services

​
Step 4: Stop the services

docker compose down -v
-v flag is used to delete volumes.
Deleting the volumes also wipes out the data stored in postgres and clickhouse.

docker exec -it langtrace npm run create-tables
If you have made changes to the prisma schema and want to apply the changes to the database, run the following command:
docker exec -it langtrace npm run create-tables
Its likely that you are using an older version of docker-compose. Update docker-compose to the latest version. Certain docker compose schema used in this project are only supported in newer versions of docker-compose. Either you update the docker compose version OR remove the depends_on property that maybe causing the error.
If clickhouse server is not starting, it is likely that the port 8123 is already in use. You can change the port in the docker-compose file.
