The Docker configuration for Cal is an effort powered by people within the community., Inc. does not provide official support for Docker, but we will accept fixes and documentation. Use at your own risk.

The Docker configuration can be found in our docker repository.


Make sure you have docker & docker compose installed on the server / system.

Build-time variables

These variables must be provided at the time of the docker build, and can be provided by updating the .env file. Changing these is not required for evaluation, but may be required for running in production. Currently, if you require changes to these variables, you must follow the instructions to build and publish your own image.




Important Run-time variables


Git Submodules

This repository uses a git submodule.

To update the calcom submodule, use the following command:

git submodule update --remote --init

For more advanced usage, please refer to the git documentation:


  • SSL edge termination: If running behind a load balancer which handles SSL certificates, you will need to add the environmental variable NODE_TLS_REJECT_UNAUTHORIZED=0 to prevent requests from being rejected. Only do this if you know what you are doing and trust the services/load-balancers directing traffic to your service.

  • Failed to commit changes: Invalid 'prisma.user.create()': Certain versions may have trouble creating a user if the field metadata is empty. Using an empty json object {} as the field value should resolve this issue. Also, the id field will autoincrement, so you may also try leaving the value of id as empty.
