NOTE: DockerHub organization has not yet been renamed.

This image can be found on DockerHub at https://hub.docker.com/r/calendso/calendso

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

#Important Notes

This Docker Image is managed by the Cal.com Community. Support for this image can be found via the repository, located at https://github.com/calcom/docker

Currently, this image is intended for local development/evaluation use only, as there are specific requirements for providing environmental variables at build-time in order to specify a non-localhost BASE_URL. (this is due to the nature of the static site compilation, which embeds the variable values). The ability to update these variables at runtime is in-progress and will be available in the future.

For Production, for the time being, please checkout the repository and build/push your own image privately.


Make sure you have docker & docker compose installed on the server / system. Both are installed by most docker utilities, including Docker Desktop and Rancher Desktop.

Note: docker compose without the hyphen is now the primary method of using docker-compose, per the Docker documentation.

#Getting Started

  1. Clone calcom-docker

    git clone https://github.com/calcom/docker.git calcom-docker
  2. Change into the directory

    cd calcom-docker
  3. Update the calcom submodule.

    git submodule update --remote --init

    Note: DO NOT use recursive submodule update, otherwise you will receive a git authentication error.

  4. Rename .env.example to .env and then update .env

  5. Build the Cal.com docker image:

    Note: Due to application configuration requirements, an available database is currently required during the build process.

    a) If hosting elsewhere, configure the DATABASE_URL in the .env file, and skip the next step

    b) If a local or temporary database is required, start a local database via docker compose.

    docker compose up -d database
  6. Build Cal.com via docker compose

    docker compose build calcom
  7. Start Cal.com via docker compose

    (Most basic users, and for First Run) To run the complete stack, which includes a local Postgres database, Cal.com web app, and Prisma Studio:

    docker compose up -d

    To run Cal.com web app and Prisma Studio against a remote database, ensure that DATABASE_URL is configured for an available database and run:

    docker compose up -d calcom studio

    To run only the Cal.com web app, ensure that DATABASE_URL is configured for an available database and run:

    docker compose up -d calcom

    Note: to run in attached mode for debugging, remove -d from your desired run command.

  8. (First Run) Open a browser to http://localhost:5555 to look at or modify the database content.

    a. Click on the User model to add a new user record.

    b. Fill out the fields (remembering to encrypt your password with BCrypt) and click Save 1 Record to create your first user.

  9. Open a browser to http://localhost:3000 (or your appropriately configured NEXT_PUBLIC_WEBAPP_URL) and login with your just created, first user.


#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: https://git-scm.com/book/en/v2/Git-Tools-Submodules


  • 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.
